WEBVTT 00:00.040 --> 00:05.080 Let's open up our anime to script in order to move this anime to game object. 00:05.320 --> 00:07.560 Uh, so so let's do that. 00:07.560 --> 00:15.280 So we will open up our anime script and let's go to top of our class and let's declare some variable. 00:15.280 --> 00:19.040 So we need the speed with how much speed we want to move. 00:19.040 --> 00:20.440 So let's do that. 00:20.440 --> 00:22.840 So firstly I'm going to give it a title. 00:23.440 --> 00:24.880 So just wait. 00:24.960 --> 00:28.040 It's lagging a little bit I really apologize for it. 00:28.440 --> 00:29.840 So just wait a moment. 00:32.400 --> 00:34.600 Uh let's now it's done. 00:34.600 --> 00:36.720 So let's go to top of our class. 00:36.720 --> 00:37.960 Let's give it a header. 00:38.440 --> 00:42.320 So header basically we just firstly we need to make square brackets. 00:42.520 --> 00:48.240 And then we have to type this header header and make this first bracket. 00:48.240 --> 00:50.920 And in quotation we can give the title. 00:50.920 --> 00:54.800 So let's say something like movement like that. 00:54.840 --> 00:58.440 Let's create a serialized field uh private. 00:58.840 --> 01:00.360 And this will be speed. 01:00.360 --> 01:02.570 So this will be a float parameter. 01:02.570 --> 01:04.570 And we can call this one something like. 01:04.610 --> 01:05.490 Move spit. 01:05.490 --> 01:08.890 Or let's simply call it work spit work spit. 01:08.890 --> 01:09.970 Something like that. 01:10.170 --> 01:16.290 And by default I'm going to give a default value something around uh, two f or two unit. 01:16.530 --> 01:20.050 And now what we will do we will move over to this update function. 01:20.210 --> 01:23.050 So this update function runs every single frame. 01:23.050 --> 01:26.370 So every single frame we need to move our enemy. 01:26.370 --> 01:30.090 So I want to move this enemy to GameObject to the left direction. 01:30.250 --> 01:37.770 And in order to move that what we have to do we basically need to use this transform dot translate function 01:37.810 --> 01:41.290 transform dot translate and then make this first bracket. 01:41.290 --> 01:42.890 So transform basically what. 01:42.930 --> 01:49.290 Basically this means we're just going over to this transform component of this enemy two GameObject. 01:49.290 --> 01:52.890 And we're using this translate function in order to move. 01:53.050 --> 01:58.930 And this translate function in brackets is going to take the direction in which direction you want to 01:58.970 --> 01:59.450 move. 01:59.450 --> 02:06.550 So since we want to move to the left direction so we can simply put a vector two dot left vector two 02:06.710 --> 02:14.830 dot left vector two dot left basically means -one inch the x and zero in the y, because we don't want 02:14.830 --> 02:19.190 to move this enemy to GameObject at all in the y direction. 02:19.190 --> 02:25.150 So and we want to move this enemy to GameObject to the left direction in the x axis. 02:25.150 --> 02:29.430 So that's why we put vector two dot vector two dot left. 02:29.470 --> 02:31.830 It's basically means -one inch the x. 02:31.830 --> 02:36.590 So it will be negative direction and one and zero in the y. 02:36.830 --> 02:43.430 And what we will do, we will multiply this with our time delta time to make frame rate constant because 02:43.430 --> 02:45.430 we are doing inside this update function. 02:45.430 --> 02:50.390 So we need to make our speed constant every single frame. 02:50.390 --> 02:53.550 So that's why we're going to multiply with time dot delta time. 02:53.550 --> 02:55.710 And let's close that up with semicolon. 02:55.710 --> 02:59.150 And we also want to multiply these things with our speed. 02:59.150 --> 03:06.160 So we can just move a little bit faster, or with how much speed we just want to move our enemy to game 03:06.200 --> 03:06.800 object. 03:06.800 --> 03:10.120 So let's multiply this whole thing with our workspace. 03:10.320 --> 03:13.280 And now we're going to press down Ctrl S to save our script. 03:13.280 --> 03:15.120 And now let's move over to unity. 03:15.320 --> 03:22.320 And you will see as soon as are we gonna start our game, this enemy, we're just gonna start moving 03:22.360 --> 03:25.040 to the left direction for this enemy to. 03:25.080 --> 03:27.920 I'm just gonna create an another ground. 03:27.920 --> 03:32.320 Simply, I'm gonna duplicate this ground GameObject from the hierarchy tab. 03:32.640 --> 03:37.000 And that ground, I want to check with this enemy to game object. 03:37.000 --> 03:40.360 So that's why uh, so we're going to do that. 03:40.360 --> 03:46.080 Or we can just simply, uh, we can do it, uh, in this ground as well. 03:46.080 --> 03:50.000 So I'm going to make the jump height of this player game object a little bit up. 03:50.040 --> 03:57.440 I'm gonna bump up the jump height of this player game object in order to jump, jump over top of this 03:57.440 --> 04:02.660 enemy game object so we can easily pass through it, and it's taking a longer time. 04:02.660 --> 04:04.060 Now it's fine. 04:04.460 --> 04:08.660 And as soon as our anime script just gets compiled, sorry. 04:09.100 --> 04:15.980 If I move over to unity, we can see underneath our anime script, we can see the title, which is movement, 04:15.980 --> 04:17.820 and we can see the work speed. 04:17.820 --> 04:19.420 By default we set it to two. 04:19.660 --> 04:25.460 And now what we're gonna do, uh, I'm going to make the jump height a little bit up, and I'm going 04:25.500 --> 04:28.220 to bump up the jump height of this player game object. 04:28.220 --> 04:32.380 So I will select simply select my player game object in a hierarchy. 04:32.660 --> 04:38.620 Let's go over to Inspector then player skip and a jump height over here I'm going to make it something 04:38.620 --> 04:39.980 like 25. 04:40.420 --> 04:42.740 So now that's uh that's great. 04:42.740 --> 04:48.100 And if I just go ahead and then click on this play button, you will see this, uh, anime two game 04:48.140 --> 04:48.500 object. 04:48.500 --> 04:52.580 Just gonna move as soon as the game just gonna start. 04:52.580 --> 04:59.060 It will start moving to the left direction with work speed that we created, uh, the work speed. 04:59.060 --> 05:05.750 And we can see indeed this animated GameObject just moving to the left side, uh, with our work speed. 05:05.750 --> 05:07.910 But it's get fall down over here. 05:08.070 --> 05:15.510 So once the enemy something over here at the end of our round, then we need to flip this enemy to the 05:15.510 --> 05:16.510 right direction. 05:16.790 --> 05:20.190 But before we do, we're gonna do a little bit one thing. 05:20.190 --> 05:22.270 So we're gonna get out of play mode. 05:22.310 --> 05:29.230 What we basically want to do, uh, we want to create a circle around this enemy to game object, uh, 05:29.630 --> 05:30.790 enemy to game object. 05:30.790 --> 05:37.470 And if this, uh, if this, uh, player game object, just get inside of this enemy game object attack 05:37.470 --> 05:41.390 range or in that circle, then we're gonna attack on this. 05:41.630 --> 05:43.950 Uh, we're gonna play the attack animation clip. 05:43.950 --> 05:48.470 Basically, we're gonna do the same thing as we have done with enemy one game object. 05:48.750 --> 05:52.590 Uh, I guess, but before we do, let's do the flip thing. 05:52.870 --> 05:54.350 Uh, so let's do it. 05:54.350 --> 05:57.310 So we will move over to our enemy two script. 05:57.310 --> 06:02.840 Basically, we will open up our animated script by double clicking on it, and let's go to top of our 06:02.840 --> 06:05.480 class and let's declare some variable. 06:05.480 --> 06:07.040 So we're going to shoot out a ray. 06:07.600 --> 06:13.480 Shoot out a ray from somewhere over here in front of this enemy two game object. 06:13.480 --> 06:16.840 And if that ray don't collide with this ground game object. 06:16.840 --> 06:20.280 So something over here, it's not gonna collide at all. 06:20.280 --> 06:24.720 So in that moment, what we're gonna do, we're gonna flip this enemy to the right direction. 06:24.920 --> 06:29.320 And in order to create the ray, we need to use a function called raycast. 06:29.480 --> 06:29.840 So. 06:30.280 --> 06:36.000 But before we do, let's create a variable in order to keep track of which direction this enemy two 06:36.040 --> 06:37.840 is are facing. 06:38.040 --> 06:41.400 So as we can notice, it's facing to the left direction. 06:41.400 --> 06:47.280 So we're going to create a private bool parameter to just keep track of which direction this enemy is 06:47.280 --> 06:47.960 looking. 06:47.960 --> 06:51.320 So let's go to our script and let's make a private. 06:52.320 --> 06:54.760 This will be bool which can be true or false. 06:54.760 --> 06:57.200 And we can call this one facing left. 06:57.240 --> 06:59.900 Sorry, we need to do it over here. 06:59.900 --> 07:03.100 So let's call this one facing left. 07:03.260 --> 07:05.740 And let's close that up with semicolon. 07:05.740 --> 07:08.460 And now I'm going to move over to this start function. 07:08.460 --> 07:12.940 So in the start of the game I'm going to set my facing left equal to true. 07:13.220 --> 07:14.300 Equal to true. 07:14.300 --> 07:16.780 And let's close that up with semicolon y. 07:16.780 --> 07:18.700 We set it to true in this start of the game. 07:18.700 --> 07:24.500 Because in the start of the game this enemy as you can see it's looking to the left direction. 07:24.500 --> 07:31.220 So that's why in the start of the game I just set, I just said that facing left parameter to true as 07:31.220 --> 07:32.140 you can notice. 07:32.140 --> 07:35.740 And now what we have to do, we need to create a shoot out the ray. 07:35.940 --> 07:41.220 And in order to shoot out the ray we need to use a function called physics 2D raycast. 07:41.340 --> 07:44.420 So let's do that and we're going to do it update function. 07:44.420 --> 07:46.380 Or we can make a function for it. 07:46.380 --> 07:48.300 But let's do it over here. 07:48.300 --> 07:51.900 Instead of creating a separate function for this. 07:52.980 --> 08:00.870 And to to shoot out the ray we need to use this physics 2D dot raycast function and this raycast function 08:00.870 --> 08:01.990 as a first argument. 08:01.990 --> 08:05.550 It's going to take the position from where you want to shoot out the ray. 08:05.590 --> 08:10.990 So we're going to create a point, basically an empty shell game object of this animator game object 08:10.990 --> 08:12.390 somewhere around here. 08:12.510 --> 08:15.070 And from that frame, we're gonna shoot out the ray. 08:15.350 --> 08:16.230 Shoot out the ray. 08:16.910 --> 08:19.670 So we need we need to create that point. 08:19.670 --> 08:21.550 And the second thing it's going to take. 08:21.550 --> 08:24.710 So if we just move over, it's going to take the direction. 08:24.710 --> 08:27.550 So we're going to shoot out in the down direction. 08:27.790 --> 08:31.750 And the third argument it's going to take the distance basically length of the ray. 08:31.750 --> 08:34.510 So we need to specify that as well. 08:34.710 --> 08:40.350 And the third and the fourth argument it's going to take the layer mask basically with which game object 08:40.350 --> 08:42.550 we want we want to check with. 08:42.590 --> 08:44.150 So we're going to check with this ground. 08:44.190 --> 08:46.830 So as a layer mask we're going to choose this ground. 08:46.910 --> 08:49.950 So we need those variable before we shoot out the ray. 08:49.950 --> 08:52.950 So let's make this one comment by double forward slash. 08:52.990 --> 08:55.030 And let's go to top of our class. 08:55.030 --> 08:58.680 And let's uh let's assign those variable first. 08:58.760 --> 09:01.360 So before we do let's give it a title. 09:01.360 --> 09:03.000 So let's create this header. 09:03.240 --> 09:06.680 And we can call this one something like ground detection. 09:06.680 --> 09:08.760 So let's call ground detection. 09:08.800 --> 09:11.600 The title we're giving is ground detection. 09:12.160 --> 09:18.880 Uh detection I really apologize if the spelling is wrong I think it's, uh fine. 09:18.880 --> 09:20.360 So now what we have to do. 09:20.360 --> 09:21.880 We need to grab the reference. 09:21.880 --> 09:24.080 So first thing we need our position. 09:24.080 --> 09:27.280 So let's create a serialized field private. 09:27.560 --> 09:34.240 And for position we need to try this transform which is responsible for position rotation and scale. 09:34.440 --> 09:39.080 And we can call this one something like ground point or check point. 09:39.400 --> 09:42.400 Uh so let's call shootout ground check point. 09:42.400 --> 09:48.280 So let's call it ground ground check point check point. 09:48.280 --> 09:51.640 Or we can simply call it check point as well. 09:51.640 --> 09:54.400 So let's call it instead ground Check Point. 09:54.400 --> 09:57.860 So I'm going to call this one Crown Shake. 09:57.900 --> 09:58.620 Point. 09:59.820 --> 10:00.300 Point. 10:00.300 --> 10:03.340 And the second thing it's going to take the direction. 10:03.340 --> 10:05.620 So we don't need to create that parameter. 10:05.620 --> 10:07.260 Since we're going to use vector two. 10:07.260 --> 10:13.980 Dot down basically means uh one in the uh sorry y in the y minus one. 10:13.980 --> 10:17.020 So it's going to be negative and zero in the x. 10:17.020 --> 10:21.260 So means basically means that it's just going to shoot out in the down direction. 10:21.260 --> 10:23.460 So we don't need to specify that. 10:23.660 --> 10:28.020 So we will uh so we can just move over to our third argument. 10:28.020 --> 10:31.820 So we need to specify the length of the array or distance. 10:31.820 --> 10:35.020 So let's create another serialized field private. 10:35.020 --> 10:36.580 And this will be float. 10:36.580 --> 10:38.740 And we can call this one array length. 10:38.940 --> 10:41.580 Or let's call it distance instead. 10:41.820 --> 10:43.660 So let's call this one distance. 10:43.660 --> 10:49.380 And by default I'm going to set it to something like zero point 5FA little bit less number. 10:49.620 --> 10:52.500 Or we can just go with 0.3 as well. 10:52.860 --> 10:54.020 Something like that. 10:54.020 --> 10:56.740 And the fourth argument we need the layer mask. 10:56.740 --> 11:01.190 So let's create another serialized field private, private. 11:01.190 --> 11:02.990 And this will be Layer Mask. 11:02.990 --> 11:08.670 And we can call this something like target layer or let's call it what is Crown. 11:09.030 --> 11:10.430 What is crown. 11:10.470 --> 11:12.670 And now let's close that off with semicolon. 11:12.950 --> 11:15.950 And let's press down Ctrl S to save our script. 11:15.950 --> 11:17.630 And let's head over to unity. 11:18.070 --> 11:21.550 So we need to assign those variable by one by one. 11:21.550 --> 11:24.910 So the first thing just gonna pop up our ground checkpoint. 11:24.910 --> 11:31.950 So we will create an empty game object or an empty game object inside this animator game object. 11:32.150 --> 11:38.470 And we're going to make that one child, uh, since, uh, we want to shoot out the ray from that point. 11:38.470 --> 11:43.390 So we're gonna create an empty child game object inside this anime game object. 11:43.750 --> 11:49.670 So as you can see, as soon as our animator script just gets compiled, we can see ground detection 11:49.670 --> 11:54.590 title, and we have the ground checkpoint as well as the distance and what is ground. 11:54.590 --> 11:55.710 So we have this. 11:55.710 --> 11:57.450 So let's create the point first. 11:57.450 --> 12:00.370 So I'm going to select my enemy two GameObject in the hierarchy. 12:00.530 --> 12:01.890 Let's right click on it. 12:01.930 --> 12:04.810 Let's create an empty empty game object. 12:04.810 --> 12:10.490 And we can call this GameObject something like Round Checkpoint as we name it the variable earlier. 12:10.490 --> 12:15.010 So I'm going to call it Ground Checkpoint and make sure you go to Inspector. 12:15.050 --> 12:16.050 Then click here. 12:16.170 --> 12:18.690 Click here if you want to choose an icon. 12:18.690 --> 12:22.010 So let's choose this yellow one, something like that. 12:22.010 --> 12:24.490 And let's select this move tool from the scene view. 12:24.490 --> 12:30.890 And let's move it in front of this you can simply say in front of this enemy two GameObject somewhere 12:31.130 --> 12:32.410 over here. 12:32.410 --> 12:35.050 So from this point we want to shoot out the ray. 12:35.050 --> 12:36.650 So that's why we created. 12:36.650 --> 12:40.050 So now we will select our enemy two GameObject in the hierarchy. 12:40.250 --> 12:45.490 And let's select this ground checkpoint and drag it over to this ground checkpoint field. 12:45.530 --> 12:48.850 Now we have the ground checkpoint or basically this position. 12:48.850 --> 12:51.450 And we are ready to shoot out the ray. 12:51.690 --> 12:52.650 And what is ground? 12:52.650 --> 12:56.090 We're going to choose our ground since we want to check with this ground. 12:56.090 --> 12:59.780 But before you choose your crown, make sure you select your crown. 12:59.780 --> 13:02.140 Then go over to Inspector and Layer. 13:02.140 --> 13:08.340 You can see it will be default, so just click on click on add layer, name the layer, whatever you 13:08.340 --> 13:08.740 want. 13:08.780 --> 13:13.900 So call it something like Crown and after that make sure you select that game object one more time. 13:13.900 --> 13:22.020 So in our case Crown and go over to Inspector and Assign with the layer that you recently created. 13:22.020 --> 13:26.500 So as you can notice, I assigned this ground as a ground layer. 13:26.500 --> 13:28.420 We can notice in Inspector. 13:28.420 --> 13:31.460 So I will head over to my animator game object. 13:31.460 --> 13:37.180 And what is ground I'm gonna choose this ground says since the ray I want to check with this ground 13:37.220 --> 13:37.980 game object. 13:38.300 --> 13:41.820 And also we need to move over to this overrides in inspector. 13:41.860 --> 13:42.900 Then apply all. 13:42.900 --> 13:48.220 So the changes we made, it's going to be saved into this animator GameObject prefab as well. 13:48.460 --> 13:54.820 And now we're gonna open up our animator script because we have all of the reference by now and we are 13:54.820 --> 13:56.260 ready to create the ray. 13:56.260 --> 13:56.430 rate. 13:56.630 --> 14:01.270 So we're going to remove these two, uh slashes forward slashes. 14:01.430 --> 14:04.630 So this physics 2D raycast as a first argument. 14:04.630 --> 14:07.550 It's going to take the point from where we want to shoot out. 14:07.550 --> 14:13.270 So we're going to pass our current checkpoint dot position because from this position we want to shoot 14:13.270 --> 14:14.190 out that way. 14:14.350 --> 14:16.710 And the second thing it's going to take the direction. 14:16.710 --> 14:19.190 So we're going to put this vector to dot down. 14:19.230 --> 14:24.190 Vector two dot down basically means that minus one and -one inch the y. 14:24.230 --> 14:27.190 So it's going to be down and zero in the x. 14:27.190 --> 14:31.750 So since we don't want to shoot out the ray in the x axis or horizontally. 14:31.750 --> 14:34.390 So that's why we pass vector to dot down. 14:34.430 --> 14:38.070 It basically means x into zero and -one inch the y. 14:38.110 --> 14:40.270 So it's going to be in the down direction. 14:40.510 --> 14:45.350 And this and the third argument it's going to take the distance or the length of the ray. 14:45.630 --> 14:49.630 So we're going to pass our distance or basically length of the ray. 14:49.630 --> 14:55.270 And the fourth argument it's going to take the layer mask uh basically which with which game object 14:55.270 --> 14:56.970 we want to check with. 14:56.970 --> 14:58.930 So I'm going to pass my what is ground. 14:58.930 --> 15:01.010 And we do know that what is ground. 15:01.130 --> 15:03.570 Uh, as a I have chosen this crown. 15:03.570 --> 15:04.850 So we're going to check the rate. 15:04.850 --> 15:07.210 Just going to check with that ground game object. 15:07.210 --> 15:12.930 So this function physics 2D dot raycast, it's gonna shoot out the ray from this position in the down 15:12.970 --> 15:14.730 direction with this much of length. 15:14.730 --> 15:16.970 And it's going to check with our ground. 15:16.970 --> 15:18.570 So now what we have to do. 15:18.570 --> 15:22.770 So this right over here, it's gonna give us true or false value. 15:22.770 --> 15:28.410 So what we will do we're going to store it into a raycast variable because this is a ray. 15:28.610 --> 15:32.010 So that's why we need to put it a variable which should be recast. 15:32.050 --> 15:37.850 So what we have to do we need to type this raycast hit variable type hit 2d variable. 15:37.850 --> 15:39.850 And we have to name the parameter. 15:39.850 --> 15:42.770 So we can simply call it something like hit info. 15:43.050 --> 15:44.530 So let's call it hit info. 15:44.530 --> 15:46.530 And let's set equal to this. 15:46.530 --> 15:49.530 So we need to store into this raycast hit 2d. 15:49.570 --> 15:49.970 Why. 15:50.010 --> 15:52.650 Because this physics 2D raycast is a. 15:52.850 --> 15:54.610 It's gonna work like a ray. 15:54.650 --> 15:58.420 So that's why we need to store the result into this array cache. 15:58.420 --> 16:03.220 Hit 2d parameter and we just call it call that parameter. 16:03.220 --> 16:04.060 Hit info. 16:04.260 --> 16:10.500 So this hit info can be true or false depending upon if the array is colliding with this crown or not. 16:10.540 --> 16:13.900 If it's, then this right over here gonna be true. 16:13.900 --> 16:16.420 So that's why this hit info just going to be true. 16:16.420 --> 16:19.300 Because we directly setting it as you can notice. 16:19.660 --> 16:25.740 Uh, and if the ray don't collide with this, uh, this crown, then it's gonna give us false value. 16:25.740 --> 16:28.580 So this right over here, uh, gonna be false. 16:28.580 --> 16:32.020 So that's why this hit info parameter just gonna be false. 16:32.020 --> 16:38.340 So what we want to do now in the next, uh, in the next section, we want to check if the ray don't 16:38.340 --> 16:39.700 collide with that crown. 16:39.700 --> 16:41.060 So what are we gonna do? 16:41.100 --> 16:42.700 We're gonna use this if condition. 16:42.700 --> 16:45.580 So let's make first bracket and some curly brackets. 16:45.580 --> 16:47.340 So what we want to check over here. 16:47.340 --> 16:51.260 We basically want to check if hit info is equals. 16:51.300 --> 16:52.620 Equals to false. 16:52.620 --> 16:56.800 Basically means that this ray that we created from this point. 16:56.800 --> 16:59.240 It's not colliding with this ground game object. 16:59.240 --> 17:03.320 And we do know that if the enemy is somewhere over here. 17:03.320 --> 17:09.800 So if I take my enemy GameObject somewhere here, as you can notice right over here, the rain not gonna 17:09.800 --> 17:12.400 collide at all with this ground game object. 17:12.800 --> 17:19.360 So in that moment, what we're doing, as you can see if I hit info is equals equals to false basically 17:19.360 --> 17:21.080 means the ray is not colliding. 17:21.240 --> 17:24.400 And over here it's not gonna collide at all. 17:24.400 --> 17:25.960 So now what we need to do. 17:26.000 --> 17:30.840 We basically need to flip this enemy to GameObject to the right direction. 17:30.840 --> 17:33.920 But before we do, let's, uh, basically print out a message. 17:33.920 --> 17:40.280 So I'm gonna move my enemy over here and to print out the message, we're going to type this, uh, 17:40.320 --> 17:43.040 debug debug dot log. 17:43.200 --> 17:47.640 And we can simply say something like flip enemy to the right direction. 17:47.640 --> 17:55.120 So let's say something like flip enemy to the right, right direction. 17:55.970 --> 17:57.010 Direction. 17:57.650 --> 17:58.370 Direction. 17:58.370 --> 18:00.530 And let's close that up with semicolon. 18:00.530 --> 18:01.930 So whenever the rain. 18:01.970 --> 18:07.130 Not going to collide with this crown then this message just going to pop up because we're checking over 18:07.130 --> 18:07.650 here. 18:07.650 --> 18:14.810 If hit info equals equals to false basically means that Ray not colliding with that crown game object 18:14.810 --> 18:15.570 at all. 18:15.610 --> 18:18.490 Now I'm going to press Ctrl s to save my script. 18:18.490 --> 18:20.290 And now let's move over to unity. 18:20.530 --> 18:28.010 So as soon as, uh, we will be at the end of this crown, basically that enemy two game object, then 18:28.010 --> 18:33.530 that message just going to pop up right away says, uh, flip enemy to the right direction. 18:33.690 --> 18:37.410 But the problem is that we're not gonna able to see our Ray. 18:37.890 --> 18:44.770 Uh, so as you can see, script just gets compiled, but the problem is that we're not able to see our 18:44.770 --> 18:46.610 way, and we just want to see. 18:46.610 --> 18:48.010 So it's gonna be perfect. 18:48.010 --> 18:54.250 And we do know that in order to create it, we need to use a function calls on draw gizmo selected. 18:54.250 --> 18:59.460 So let's use that in order to see the array or in order to draw the array. 18:59.460 --> 19:02.860 So we're going to open up our animator script by double clicking on it. 19:02.860 --> 19:07.300 And let's go to bottom somewhere over here you can make it anywhere. 19:07.820 --> 19:09.740 It doesn't need to be in order. 19:09.740 --> 19:13.660 So you can just make wherever you would like to go with. 19:13.940 --> 19:17.780 So we have to use this on draw gizmo selected function. 19:17.980 --> 19:20.820 And this function just going to draw what we want to draw. 19:20.820 --> 19:25.980 And this function just unity in build function means a unity just going to call itself. 19:26.140 --> 19:27.780 So we want to draw the array. 19:27.780 --> 19:33.060 But before we want to draw the array we need to check if we assign it this ground check point or not 19:33.700 --> 19:35.260 ground check point or not. 19:35.300 --> 19:38.180 Basically let's use let's draw the array. 19:38.860 --> 19:44.900 So firstly we will check if we assign it that uh basically that ground check point or not. 19:44.900 --> 19:47.660 So what we will do, we will use this if condition. 19:47.660 --> 19:52.420 So let's make first bracket and some curly brackets and what we want to check over here. 19:52.460 --> 19:55.800 We basically want to check if our ground checkpoint. 19:55.800 --> 19:57.840 If it's not equal to null. 19:58.120 --> 19:59.680 What this basically means. 19:59.680 --> 20:03.480 So you need to use this exclamation mark and then this equal sign. 20:03.600 --> 20:10.400 So if ground checkpoint is not equal to null it basically means that this ground check field right over 20:10.400 --> 20:15.000 here underneath our enemy two script is not empty. 20:15.040 --> 20:18.640 Basically we just drag it this ground checkpoint to this ground checkpoint. 20:18.720 --> 20:24.360 So as you can see, if ground checkpoint is not equal to null basically means that we assign it. 20:24.400 --> 20:27.160 So now we're going to draw the draw the ray. 20:27.200 --> 20:32.160 Else we're not going to draw the ray because we need a reference of this ground checkpoint. 20:32.200 --> 20:34.000 After that we can draw the ray. 20:34.040 --> 20:39.360 So that's why before we drawing we're checking if ground checkpoint is not equal to null. 20:39.400 --> 20:44.520 Basically means we just drag it our ground check to ground checkpoint field. 20:44.560 --> 20:47.240 Basically we have the reference of that position. 20:47.240 --> 20:49.680 And now we are ready to draw the ray. 20:49.720 --> 20:52.960 And in order to draw the ray we need to use this gizmos. 20:53.320 --> 21:02.290 Sorry we need to use these gizmos dot draw ray function and this draw ray function as a first argument. 21:02.290 --> 21:05.370 It's going to take the point from where you want to draw. 21:05.370 --> 21:09.850 So we will pass our ground check point and we have to access the position. 21:09.850 --> 21:11.850 So we're going to type this dot position. 21:11.850 --> 21:14.410 And the second thing it's going to take the direction. 21:14.410 --> 21:17.090 So we will pass this vector to dot down. 21:17.130 --> 21:24.890 It's basically means uh minus one is zero in the XX0 in the x and minus one in the y. 21:24.930 --> 21:27.050 So basically means in the down direction. 21:27.250 --> 21:33.490 And we will multiply this, uh, direction with our length of the ray so we can see our ray. 21:33.610 --> 21:39.570 So we will multiply our direction with the length of the ray which is in our case distance. 21:39.570 --> 21:42.090 And now we're going to close that off with semicolon. 21:42.090 --> 21:44.450 So I want to draw with yellow color. 21:44.450 --> 21:48.010 So that's why before I draw I want to specify the color. 21:48.010 --> 21:53.570 If you don't specify then it's just gonna draw the ray with white color. 21:53.570 --> 21:58.740 But if you want to choose a different color so you can do that before you draw the ray. 21:58.900 --> 22:00.620 So I want to choose an. 22:00.660 --> 22:04.780 In order to choose the color, we need to use this gizmos dot color function. 22:04.940 --> 22:06.980 Sorry, this gizmos dot color. 22:07.260 --> 22:10.140 And you can set equal to color that you like. 22:10.140 --> 22:14.940 So I'm going to set color dot yellow a yellow something like that. 22:14.940 --> 22:17.500 And let's close that up with semicolon. 22:17.500 --> 22:21.260 And we're going to press down control S in order to save our scape. 22:21.380 --> 22:26.780 And if we move over to unity as soon as our enemy two script just gonna compiles. 22:26.780 --> 22:34.700 You able to see the ray by now because we just using that on draw gizmo selected function in order to 22:34.740 --> 22:35.660 draw the ray. 22:35.660 --> 22:38.420 So just wait a little moment and you will see that. 22:39.660 --> 22:43.620 And we can play around with the distance basically length of the ray. 22:43.620 --> 22:45.180 And by now we can notice. 22:45.180 --> 22:50.580 So if I select my animator GameObject in the hierarchy and select this move tool in the scene view and 22:50.580 --> 22:53.940 move it somewhere over here, we can see the ray by now. 22:54.080 --> 22:56.960 so I want to make the length a little bit. 22:57.000 --> 22:57.760 I just want to. 22:57.800 --> 22:58.920 Bump up the value. 22:59.040 --> 23:03.440 So I will move over to this distance parameter underneath my animator script. 23:03.440 --> 23:05.640 And let's make it something around one. 23:05.840 --> 23:07.000 And this is fine. 23:07.000 --> 23:09.200 So I'm gonna move it somewhere around here. 23:09.400 --> 23:15.680 And if the enemy is somewhere around here, so they're not gonna collide with this game object. 23:15.680 --> 23:20.360 So that message just going to pop up says flip enemy to the right direction. 23:20.360 --> 23:21.680 So let's have a look on that. 23:21.680 --> 23:23.520 So I'm going to select my console tab. 23:23.520 --> 23:27.600 And let's click on this play button in the top in order to play our game. 23:27.960 --> 23:35.240 And you will see as soon as we will be at the end of the edge of the of this ground, you will see that 23:35.240 --> 23:39.840 message just going to pop up says flip enemy to the right direction. 23:40.760 --> 23:43.560 So if I just jump over, you will see. 23:43.920 --> 23:50.080 As you can see, as soon as we we are here, the message just gets pop up. 23:50.080 --> 23:54.650 And still the message just getting pop up says flip enemy to the right direction. 23:54.650 --> 23:54.970 Why? 23:55.010 --> 23:58.730 Because the ray not colliding with this ground, as you can see. 23:58.970 --> 24:01.050 So I'm gonna get out of play mode. 24:01.050 --> 24:05.650 So instead of doing this, we need to flip this enemy to the right direction. 24:05.650 --> 24:12.130 So if I select my enemy to GameObject in the hierarchy, then go over to Inspector Transform and Rotation 24:12.410 --> 24:14.450 add rotation and in the y. 24:14.490 --> 24:22.090 If I put 180 or -180, as you can see, as soon as we put it, it flips to the right direction. 24:22.090 --> 24:25.010 So we basically need to change the Euler angles. 24:25.010 --> 24:31.090 So we basically do gonna do the same thing as we have done with our enemy one game object. 24:31.090 --> 24:33.330 So we're gonna approach the same way. 24:33.370 --> 24:34.930 So I'm going to set back to zero. 24:35.130 --> 24:38.690 So to do that instead of printing out message we need to flip. 24:38.850 --> 24:43.090 So let's double click on this message in order to move over to that line of code. 24:43.090 --> 24:46.930 So instead of printing out message we just want to flip. 24:47.090 --> 24:48.530 And in order to flip. 24:48.530 --> 24:52.050 But before we flip we need to check which direction we going. 24:52.250 --> 24:57.110 So as you can notice, this enemy just facing to facing left. 24:57.150 --> 25:01.030 Basically this enemy looking to the left direction. 25:01.030 --> 25:06.630 So before we flip, we also need to check in which direction this enemy is facing. 25:06.910 --> 25:09.950 So before we flip we will check. 25:10.150 --> 25:11.790 So let's use this if condition. 25:11.830 --> 25:14.430 Let's make first bracket and some curly brackets. 25:14.430 --> 25:16.270 And what we want to check over here. 25:16.270 --> 25:21.230 We basically want to check if facing left is true equals equals to true. 25:21.470 --> 25:27.350 Or you can just leave like this basically means that this enemy is looking to the left direction. 25:27.350 --> 25:31.590 So what we need to do now so the enemy is gonna be over here. 25:31.590 --> 25:34.670 So basically we need to move over to Euler angles. 25:34.670 --> 25:37.550 And we need to set the y to -180. 25:37.590 --> 25:41.630 And we do know once we're gonna set that it's going to flip to the right direction. 25:41.630 --> 25:46.830 And after flipping to the right direction we need to set that facing left parameter to false. 25:46.830 --> 25:47.230 Why? 25:47.390 --> 25:53.640 Because if I set it to -180 or 180 sorry Of 180. 25:54.000 --> 25:59.840 So in this situation, this enemy will no longer just gonna face to the left direction. 25:59.840 --> 26:05.240 So that's why after flipping this enemy, we need to set the facing left parameter to false. 26:05.240 --> 26:10.960 Because in that moment, this enemy would two game object just gonna look to the right direction. 26:10.960 --> 26:11.680 So that's why. 26:11.680 --> 26:13.240 So I'm going to set back to zero. 26:13.640 --> 26:16.120 And let's move it somewhere around here. 26:16.280 --> 26:18.000 And let's go to our script. 26:18.000 --> 26:23.560 So to flip that we need to use this transform then dot Euler angles. 26:23.560 --> 26:27.640 And this is going to have x x y and z angle. 26:27.840 --> 26:29.400 So sorry z axis. 26:29.400 --> 26:33.080 So we're going to set equal to new vector three which also going to have. 26:33.080 --> 26:38.000 So which also gonna have x axis y axis and the z axis. 26:38.000 --> 26:43.960 So in the y what we need to do we need to put a we basically need to put one ATF. 26:44.120 --> 26:50.560 And we do know that as soon as we're gonna put one ATF minus one ATF, it's gonna flip to the right 26:50.560 --> 26:51.200 direction. 26:51.200 --> 26:54.170 And we don't want to mess around z axis. 26:54.170 --> 26:56.570 So we're going to put zero f in Z. 26:56.570 --> 26:59.930 And we're going to do the same thing in the x axis zero f. 27:00.130 --> 27:04.530 And now after flipping this we need to set this facing left parameter to false. 27:04.570 --> 27:05.010 Why? 27:05.170 --> 27:10.450 Because as soon as we're gonna flip this enemy to the right direction, it's no longer able to look 27:10.450 --> 27:11.690 to the left direction. 27:11.690 --> 27:17.210 So that's why after flipping this, now, we're gonna set facing left equal to false. 27:17.730 --> 27:18.090 False. 27:18.130 --> 27:20.330 And let's close that up with semicolon. 27:20.330 --> 27:24.810 And now I'm going to press down Ctrl s on my keyboard in order to save my script. 27:24.810 --> 27:26.570 And then move over to unity. 27:26.610 --> 27:33.170 You will see as soon as this enemy is just going to be at the end of this crown, this enemy just kind 27:33.170 --> 27:35.210 of flips to the right direction. 27:35.730 --> 27:37.370 So let's have a look on that. 27:37.370 --> 27:44.610 So just wait a moment and I'm going to take this enemy over here and let's have a look. 27:44.610 --> 27:47.050 So let's click on this play button in the top. 27:47.050 --> 27:49.130 And in order to play our game. 27:49.130 --> 27:51.010 And let's take a look on this. 27:56.830 --> 27:58.430 So just wait a moment. 27:59.870 --> 28:01.510 And if we jump over. 28:01.510 --> 28:04.150 So it's gonna flip as soon as we can see. 28:04.190 --> 28:11.230 As soon as enemy was over here, it just get flipped to the right direction and we can see if we just 28:11.230 --> 28:16.550 select my enemy two GameObject in the hierarchy, move over to Inspector Transform and Rotation. 28:16.550 --> 28:19.150 We can see in the Y is 180. 28:19.350 --> 28:27.270 And now if the enemy is somewhere over here, we again need to set the Y to zero. 28:27.430 --> 28:33.630 So what we basically have to do if the enemy is over here, let's suppose it's looking to the right 28:33.630 --> 28:34.390 direction. 28:34.390 --> 28:36.790 So enemy just gonna be over here. 28:36.790 --> 28:40.390 So they're not gonna collide with this ground game object at all. 28:40.390 --> 28:44.230 So what we need to do now, we need to set back y to zero. 28:44.230 --> 28:50.150 And we do know that if we set back to zero, we can see this enemy just gonna look to the left direction 28:50.190 --> 28:51.510 one more time. 28:51.510 --> 28:57.960 So we need to set back to zero as well as after, uh, flipping this enemy to the left direction, we 28:57.960 --> 29:00.640 need to set that facing left parameter to true. 29:01.040 --> 29:01.400 Why? 29:01.640 --> 29:06.680 Because as you can see, as soon as we're gonna flip to the left direction, we will look to the left 29:06.680 --> 29:07.200 direction. 29:07.200 --> 29:11.200 So that's why we need to set that parameter one more time to true. 29:11.200 --> 29:14.280 So that's why we created that facing layer parameter. 29:14.280 --> 29:19.680 In order to check which direction this enemy to game object is facing. 29:19.840 --> 29:21.360 So basically that is the thing. 29:21.360 --> 29:22.440 So let's do it. 29:22.440 --> 29:26.400 So now what we're going to do, we're going to open up our enemy script once again. 29:26.400 --> 29:35.400 And we will check else if our enemy if our enemy looking to the left or sorry if our enemy is looking 29:35.440 --> 29:36.840 to the right direction. 29:36.880 --> 29:42.600 So then what we're going to do, we we can simply copy this line of code by Ctrl C, and we can simply 29:42.600 --> 29:44.720 paste it over here by Ctrl V. 29:44.960 --> 29:48.480 So in the Y what we can do, we can simply put zero f. 29:48.480 --> 29:53.810 And we do know that as soon as we're going to put zero F it's gonna flip to the left direction. 29:53.810 --> 29:58.970 And after flipping to the left direction, we're gonna set this facing left parameter right over here 29:58.970 --> 30:00.930 to true once again. 30:00.930 --> 30:02.450 So we're gonna set it to true. 30:02.450 --> 30:06.050 So firstly what we're checking we're checking if hit info is false. 30:06.050 --> 30:09.730 Basically means the array is not colliding with this ground. 30:09.730 --> 30:13.930 And in the else condition we're checking if we're looking to the right direction. 30:13.930 --> 30:16.210 Then we're setting again to zero. 30:16.610 --> 30:20.690 And after that we're setting facing left parameter to true as you can see. 30:20.890 --> 30:22.650 So now we are done. 30:22.810 --> 30:30.210 And let's press down Ctrl S to save our script I'm going to press Ctrl S to save my escape. 30:30.290 --> 30:32.410 And now let's move over to unity. 30:32.410 --> 30:37.090 So you will able to notice this armature schooner petrel around this ground. 30:37.290 --> 30:37.890 Uh ground. 30:37.930 --> 30:39.730 It's one one. 30:39.930 --> 30:43.890 It's gonna gonna be at the end of the left direction. 30:43.890 --> 30:46.010 It's gonna flip to the right direction. 30:46.050 --> 30:49.730 Basically, this enemy is just gonna start moving to the right direction. 30:49.730 --> 30:53.070 If the enemy to Two is something over here. 30:53.070 --> 30:54.310 So let's check it. 30:54.310 --> 30:58.550 And let's click on this play button in the top in order to play our game. 30:58.550 --> 31:00.510 And let's take a look on this. 31:00.510 --> 31:06.510 So this anime two is just gonna patrol around this ground, uh, depending upon which direction it's 31:06.510 --> 31:06.870 going. 31:06.910 --> 31:09.750 If it's at the end, then it's gonna flip itself. 31:09.950 --> 31:11.270 So let's have a look. 31:11.270 --> 31:15.350 So if I jump over it, we can see it's gonna flip. 31:15.350 --> 31:17.430 Now it's flipped to the right direction. 31:17.710 --> 31:24.270 And if we if the enemy is here, it's gonna flip one more time to the left direction, as you can see. 31:24.310 --> 31:24.830 Indeed. 31:25.230 --> 31:30.990 And if I pause my game by clicking on this pause button in the top, then go over to Inspector. 31:31.030 --> 31:35.670 As you can see in the Y, we just set rotation back to zero. 31:35.950 --> 31:42.710 And if if you want to see that private parameter which is bool parameter that we created which is facing 31:42.710 --> 31:45.310 left, then you need to move over to inspector. 31:45.310 --> 31:47.230 In the top right you can see three dots. 31:47.230 --> 31:50.190 So just click there and then click on this debug mode. 31:50.190 --> 31:54.840 And now we're going to able to notice our, uh, private parameters. 31:54.840 --> 32:00.760 And we can see facing left as soon as we click on that debug mode underneath our enemy two script, 32:00.760 --> 32:02.960 we can notice facing left is checked. 32:02.960 --> 32:07.160 Basically means we just set back to true, uh, set back to true. 32:07.160 --> 32:08.680 And we can check that out. 32:08.680 --> 32:14.280 And you will see this parameter just going to be uncheck or check basically means true or false depending 32:14.280 --> 32:17.040 upon which direction this enemy is going. 32:17.080 --> 32:23.280 As you can see, as soon as enemy is over here then this facing left just getting true because it's 32:23.280 --> 32:24.880 looking to the left direction. 32:24.880 --> 32:33.480 And once the enemy, sorry, once the enemy is, uh, somewhere around here, uh, then the facing left 32:33.520 --> 32:39.840 just gets false because this enemy just flips to the right direction, as you can notice underneath 32:39.840 --> 32:41.160 your enemy to script. 32:41.160 --> 32:45.840 And let's suppose you just want to go back in inspector mode then what you can do. 32:45.840 --> 32:50.120 So firstly I'm going to get out of play mode by clicking on this play button in the top. 32:50.360 --> 32:51.340 And to go back. 32:51.380 --> 32:55.700 Just go over to Inspector one more time and then go over to top right. 32:55.700 --> 33:01.620 Click on that three dots and then click on this normal in order to go back in normal mode. 33:01.980 --> 33:10.260 And one thing I have to mention that if you don't use this hit info, basically, if you just put exclamation 33:10.260 --> 33:15.420 mark right in front of this hit info parameter, it basically means the same thing. 33:15.460 --> 33:17.820 Basically means hit info is false. 33:17.820 --> 33:21.860 So you can simply just put this exclamation mark. 33:21.900 --> 33:25.660 It basically means false or it's basically the same thing. 33:25.780 --> 33:29.300 Hit info equals equals to false means the same thing. 33:29.580 --> 33:35.340 So I hope you get the idea that how you can do it and make sure if you change anything inside this anime 33:35.620 --> 33:40.300 script in the hierarchy, then go over to Inspector Overrides and then apply all. 33:40.460 --> 33:47.020 And also you also press down Ctrl S on your keyboard in order to save your project. 33:48.500 --> 33:51.500 So I hope you get the idea that how you can do it.
