WEBVTT 00:00.280 --> 00:01.600 We have a little bug. 00:01.640 --> 00:03.880 Let me show you that to you. 00:03.880 --> 00:07.200 So let's click on this play button in the top to play our game. 00:07.520 --> 00:10.480 Let's jump over top of this anime game. 00:10.520 --> 00:12.080 Object anime. 00:12.080 --> 00:15.880 Just not gonna look towards in the direction player is going. 00:15.880 --> 00:19.840 So we need to flip our enemy in the direction player is going. 00:19.880 --> 00:24.000 Once our player gets in attack range of this enemy one. 00:24.000 --> 00:24.800 Let me show you. 00:24.800 --> 00:27.720 As you can see, it's playing the arrow animation clip. 00:27.720 --> 00:34.480 So if I jump over on it, uh, as you can see, enemy is not looking to the right direction. 00:34.800 --> 00:36.840 The player is just going. 00:36.840 --> 00:40.480 So we need to flip this enemy in the right direction as well. 00:40.520 --> 00:46.640 If the, uh, if the player is, uh, player is going to the right direction. 00:46.640 --> 00:48.360 So let's get out of play mode. 00:48.360 --> 00:53.800 So what we will do, we're just going to create a parameter to just keep track of which direction this 00:53.840 --> 00:55.520 enemy is facing. 00:55.520 --> 01:00.840 And then we're going to check we also need our player transform or basically player position. 01:01.170 --> 01:09.330 And we also are just going to create our parameter in order to check which direction this enemy is facing. 01:09.410 --> 01:13.130 So let's open up our enemy script by double clicking on it. 01:13.130 --> 01:17.290 And let's go to top of our class and let's create those two variables. 01:17.370 --> 01:20.210 So the first thing we need our player position. 01:20.210 --> 01:22.730 So let's create another serialized field. 01:23.930 --> 01:28.650 For position we need to type transform serialized field private. 01:29.010 --> 01:32.610 And this will be transform simply position. 01:32.610 --> 01:35.770 And we can call this one something like player position. 01:35.770 --> 01:37.610 Or let's simply call it player. 01:37.850 --> 01:41.290 And the second thing we need are our parameter. 01:41.290 --> 01:45.890 In order to keep track of which direction our enemy is facing. 01:45.890 --> 01:48.410 So let's create another private parameter. 01:48.410 --> 01:53.090 It doesn't need to be public and that will be bool, which can be true or false. 01:53.090 --> 01:57.570 And we can call this one something like facing left facing left. 01:57.570 --> 01:59.770 And we're going to close that up with semicolon. 01:59.970 --> 02:02.460 And we will move over to this stat function. 02:02.460 --> 02:06.260 So we do know that stat function get called in the start of the game. 02:06.260 --> 02:10.500 So in this start of the game we're gonna set facing left equal to true. 02:10.780 --> 02:12.900 And let's close that up with semicolon. 02:12.900 --> 02:14.180 Why we have done this. 02:14.180 --> 02:16.060 If we move over to unity. 02:16.100 --> 02:19.140 As you can see we're looking to the left direction. 02:19.140 --> 02:23.740 So that's why facing left in the start of the game I just set equal to true. 02:23.780 --> 02:24.820 As you can see. 02:24.980 --> 02:27.740 Now we're going to save our script by Ctrl s. 02:27.780 --> 02:31.140 Now let's move over to unity and let's have a look. 02:31.500 --> 02:35.740 So we will be able to notice that uh notice that. 02:35.740 --> 02:42.940 So underneath our enemy one script a another filter is gonna pop up and it will, it will say something 02:42.940 --> 02:44.340 like player transform. 02:44.340 --> 02:48.980 So we need to drag our player transform or player position into that field. 02:48.980 --> 02:53.100 So we will have the player reference, uh player position reference. 02:53.100 --> 02:58.540 And after that we can just flip our enemy one in the direction player is going. 02:58.740 --> 03:05.300 So just wait a moment and once it's done, we can just drag the reference into that slot underneath 03:05.300 --> 03:06.980 our enemy one script. 03:07.140 --> 03:13.500 So now our script just gets compiled, as you can see, and we can see underneath our enemy. 03:13.540 --> 03:19.180 One script underneath our attack title player and it says None Transform. 03:19.180 --> 03:23.660 So let's select the player GameObject in the hierarchy and let's drag it over to that field. 03:23.700 --> 03:29.340 Now we can see we have the player transform, or you can simply say we have player position and now 03:29.340 --> 03:30.660 we can just flip that. 03:30.660 --> 03:37.020 So let's open up our enemy one script one more time, and let's make a function in order to basically 03:37.020 --> 03:38.340 flip our enemy. 03:38.340 --> 03:40.660 So let's make it somewhere around here. 03:40.940 --> 03:43.220 So for function we're going to type y. 03:43.260 --> 03:45.940 And we can call this function to something like flip. 03:46.140 --> 03:48.940 And let's make first bracket and some curly brackets. 03:49.140 --> 03:51.380 And what we want to check over here. 03:51.380 --> 03:57.820 We basically want to check that this uh let's suppose if I select my player and then select this move 03:57.860 --> 03:58.860 tool in the scene view. 03:58.860 --> 04:05.990 And let's move it somewhere around here, as you can see in this In this time, the player position 04:05.990 --> 04:10.910 in the x axis will be greater than position in the x axis, as you can see. 04:11.110 --> 04:18.390 So enemy x position will be lesser than enemy player X position less than our player x position. 04:18.670 --> 04:22.510 So what we can simply do right over here we we will check. 04:22.510 --> 04:23.750 So first thing we will check. 04:23.750 --> 04:27.630 So let's make if condition then first bracket and some curly brackets. 04:27.710 --> 04:29.710 So what we want to check over here. 04:29.710 --> 04:38.390 We basically want to check if our transform dot position dot x if it's lesser than player. 04:38.390 --> 04:40.990 So we will going to player than position. 04:40.990 --> 04:43.190 And we're going to access the x axis. 04:43.270 --> 04:49.270 So what we're doing over here we basically checking if a transform dot position dot x basically means 04:49.270 --> 04:51.470 enemy position in the x axis. 04:51.510 --> 04:54.670 If it's lesser than player position in the x axis. 04:54.670 --> 05:00.390 As you can see, we are going over to player and then accessing the position and then accessing the 05:00.390 --> 05:07.080 x position, and we checking if our enemy position in the x axis is lesser than player position in the 05:07.080 --> 05:08.000 x axis. 05:08.000 --> 05:13.720 So if the player is somewhere around here, as you can see, it's going to be play enemy position in 05:13.760 --> 05:19.040 the x axis will be lesser than player position in the x axis, as you can see. 05:19.440 --> 05:24.360 At the same time, we will check if our enemy is facing to the left direction. 05:24.360 --> 05:28.920 If that is the case, then we need to flip our enemy to the right direction. 05:28.920 --> 05:30.600 So we also want to check. 05:30.960 --> 05:31.960 So what we will do. 05:31.960 --> 05:34.160 So we're going to put this an end condition. 05:34.160 --> 05:37.880 And we will check if our facing left is true. 05:37.880 --> 05:44.120 So you can if you just leave it like this it basically means true basically means that this enemy is 05:44.120 --> 05:45.720 looking to the left direction. 05:45.720 --> 05:51.520 And we do know that in the start of the game, we just said that facing left to true means we are looking 05:51.520 --> 05:52.680 to the left direction. 05:52.880 --> 05:58.280 So right now what we have to do, we need to flip this enemy to the right direction, and we need to 05:58.320 --> 06:01.240 set that facing left parameter to true false. 06:01.440 --> 06:05.850 Uh, because once we gonna flip this admin to the right direction? 06:05.850 --> 06:08.650 Facing left parameter will be false base. 06:08.770 --> 06:15.410 Or you can say this enemy one will be no longer able to look to look towards to the left direction. 06:15.410 --> 06:16.610 So that is the thing. 06:16.810 --> 06:18.290 And to flip this enemy. 06:18.290 --> 06:24.250 So if I select my enemy one inch the hierarchy, then go over to Inspector Transform and then rotation 06:24.250 --> 06:25.130 and in the y. 06:25.130 --> 06:31.970 If we set it to something like -180, as you can see, as soon as we put this enemy just gets flipped 06:31.970 --> 06:33.330 to the right direction. 06:33.370 --> 06:37.930 Basically, we're doing the same thing as we have done inside this player script. 06:37.930 --> 06:39.650 So we're gonna do the same thing. 06:39.650 --> 06:41.010 So I'm going to set back to zero. 06:41.010 --> 06:44.250 So we basically have to access the Euler angles. 06:44.250 --> 06:47.690 So I'm going to select my player and let's move it over here. 06:48.050 --> 06:54.930 So if our enemy position in the x axis is lesser than player position in the x axis, at the same time 06:54.970 --> 06:57.570 our enemy is looking to the left direction. 06:57.570 --> 06:59.050 So if that is the case. 06:59.050 --> 07:01.890 So what we need to do, we need to flip our enemy. 07:02.090 --> 07:05.740 And in order to flip our enemy, we need to use this transformer. 07:05.780 --> 07:11.100 Euler angles which gonna have x x axis, y axis and the z axis. 07:11.100 --> 07:20.100 So we will set equal to a new vector three which gonna have x axis y axis, sorry y axis and z axis. 07:20.100 --> 07:22.180 And let's close that up with semicolon. 07:22.180 --> 07:28.340 So if we put in the y -180 as you seen it's just gonna flips to the right direction. 07:28.340 --> 07:30.700 So in the Y we're going to put -188. 07:30.860 --> 07:33.060 And in the zero we don't sorry. 07:33.100 --> 07:36.660 In the z axis we don't want to do anything at all. 07:36.660 --> 07:39.580 So that's why we're gonna put zero f in the z axis. 07:39.580 --> 07:42.620 And we will do the same thing in the x axis. 07:42.620 --> 07:49.500 And after flipping this enemy to the right direction, we need to set that facing left parameter to 07:49.540 --> 07:49.980 false. 07:49.980 --> 07:50.420 Why? 07:50.460 --> 07:54.820 Because this enemy will no longer able to look towards to the left direction. 07:54.820 --> 08:00.860 So that's why after flipping, we're gonna, uh, we're gonna set that facing left parameter to false. 08:00.860 --> 08:05.500 So after flipping we will set our facing left lab equal to false. 08:05.940 --> 08:07.980 Let's set equal to false. 08:08.140 --> 08:10.220 And now we need to call this flip function. 08:10.220 --> 08:12.660 But when we should call this flip function. 08:12.660 --> 08:17.940 Once this player game object gets in attack range of this enemy game object. 08:17.980 --> 08:19.980 Basically we need to call it over here. 08:19.980 --> 08:25.660 As you can see, if call info true basically means our player gets in attack range. 08:25.700 --> 08:28.540 Now what we will do we will call the flip function. 08:28.540 --> 08:29.700 Let's make first bracket. 08:29.700 --> 08:32.540 Then close that up with semicolon and flip function. 08:32.540 --> 08:34.540 Just gonna do this do these things. 08:34.540 --> 08:39.660 Firstly it's going to check the distance uh distance in the x axis. 08:39.700 --> 08:42.940 If it's lesser than player position in the x axis. 08:42.980 --> 08:46.060 At the same time enemy is looking to the left direction. 08:46.060 --> 08:52.660 Then we flipping our enemy to the right direction and after flipping we just setting setting this facing 08:52.660 --> 08:53.380 left to false. 08:53.380 --> 08:57.260 Because in that moment we're going to look towards to the right direction. 08:57.260 --> 09:00.460 So that's why we set facing left parameter to false. 09:00.460 --> 09:03.620 Once we flip our enemy to the right direction. 09:03.620 --> 09:06.590 And now we're going to press down Ctrl S to save our script. 09:06.590 --> 09:08.470 And now let's move over to unity. 09:08.870 --> 09:15.630 So as soon as our player just gonna surpass our enemy one GameObject in the x axis, you will see this 09:15.670 --> 09:20.670 enemy just flips to the right direction or in the direction the player is going. 09:20.710 --> 09:23.350 Basically, it's gonna flip to the right direction. 09:24.030 --> 09:29.630 And so just wait a little moment and once it's done, we can just go ahead and check. 09:29.910 --> 09:30.990 Check that out. 09:31.310 --> 09:38.430 And now I'm going to take my player and I'm gonna move it a little bit further away from this enemy 09:38.470 --> 09:39.510 one GameObject. 09:39.510 --> 09:43.630 So let's click on this play button in the top in order to play our game. 09:43.630 --> 09:45.590 And let's have a look on this. 09:48.990 --> 09:56.350 So just wait a moment and let's get in attack range and let's surpass this enemy. 09:56.350 --> 10:02.910 So if we surpass this enemy, as you can see, as soon as we have done it, enemy is now looking to 10:02.950 --> 10:04.150 the right direction. 10:04.350 --> 10:10.440 But if we move to the move over to the left direction, this enemy is not flipping at all. 10:10.480 --> 10:12.720 Back to our left direction. 10:12.720 --> 10:15.280 So we also need to set this y to zero. 10:15.400 --> 10:21.080 So if I select my enemy one inch the hierarchy, then go over to Inspector and set this y rotation to 10:21.120 --> 10:21.560 zero. 10:21.680 --> 10:26.440 As you can see, as soon as we're going to do it, it's going to flip to the left direction one more 10:26.440 --> 10:26.840 time. 10:26.880 --> 10:28.280 Basically this enemy. 10:28.280 --> 10:30.760 So we also need to set back this y to zero. 10:30.920 --> 10:35.080 And also we need to set back our facing lab parameter to true. 10:35.120 --> 10:35.520 Why? 10:35.720 --> 10:40.520 Because as you can see in this moment we will look towards to the left direction. 10:40.520 --> 10:43.240 So that's why we need to flip our sorry. 10:43.360 --> 10:46.800 So that's why we need to set facing lab parameter to true. 10:46.840 --> 10:47.720 One more time. 10:47.720 --> 10:51.840 Because in this condition we just want to look towards to the left direction. 10:51.840 --> 10:57.600 So firstly we need to check the distance distance between them in the x axis as. 10:57.640 --> 10:59.120 Then we can just do that. 10:59.120 --> 11:02.720 So let's get out of play mode and let's move over to our script. 11:02.760 --> 11:04.520 And over here we will check. 11:04.520 --> 11:07.130 So we're going to use this else if condition. 11:07.130 --> 11:08.330 So else if. 11:08.370 --> 11:11.010 Let's make first bracket and some curly brackets. 11:11.010 --> 11:11.450 So what. 11:11.450 --> 11:12.930 We want to check over here. 11:12.930 --> 11:20.050 We basically want to check if our current position of this enemy is greater than x in the x axis, is 11:20.050 --> 11:27.370 greater than player position in the x axis, and basically means player is over here, then what? 11:27.370 --> 11:29.130 We need to do this, we need to. 11:29.170 --> 11:34.930 If the enemy is looking to the right direction, then firstly we need to set back this y to zero. 11:34.930 --> 11:39.010 And if we set it as you can see it's going to look towards to the left direction. 11:39.130 --> 11:42.850 And also we need to set back that facing left parameter to true. 11:42.890 --> 11:48.210 Because in this situation, as you can see we're gonna look towards to the left direction. 11:48.210 --> 11:50.210 So now we're going to do that thing. 11:50.210 --> 11:57.130 So else if we will check if our transform dot position dot x basically means current position of that 11:57.130 --> 12:03.570 enemy in the x axis a if it's a if it's greater than player position in the x axis. 12:03.570 --> 12:05.010 So we will go to player. 12:05.010 --> 12:09.380 Then we're going to access the position, then we're gonna access the X position. 12:09.380 --> 12:12.820 If it's the case, means player is somewhere over here. 12:12.820 --> 12:15.940 And sorry, enemy is somewhere over here. 12:15.940 --> 12:17.460 And player is here. 12:17.460 --> 12:24.260 So as you can see, player, an enemy in the x axis is going to be greater than player in the x axis. 12:24.260 --> 12:26.740 And we're checking over here as you can see. 12:26.900 --> 12:29.940 So current position of that enemy in the x axis. 12:29.980 --> 12:34.940 If it's greater than player position in the x axis at the same time we will check. 12:34.940 --> 12:42.300 So we're going to use this in condition and we will check if we just look if this enemy is looking to 12:42.300 --> 12:46.420 the right direction basically means facing left parameter is false. 12:46.420 --> 12:48.220 So what we will do we will check. 12:48.260 --> 12:52.460 If so you need to put this exclamation mark basically means a. 12:52.460 --> 12:56.460 And then you have to type the parameter name which is facing left. 12:56.500 --> 13:01.820 It basically means that it's simply means that facing left parameter is false. 13:01.820 --> 13:04.060 Or you can simply do these things as well. 13:04.060 --> 13:10.590 Which is facing left equals equals to false basically means that our enemy one is looking to the right 13:10.590 --> 13:13.710 direction, or we can simply do these things. 13:13.710 --> 13:15.950 It also means the same thing. 13:16.270 --> 13:20.270 We can just put exclamation mark right in front of this facing left. 13:20.430 --> 13:26.870 It basically means that facing left parameter is false, means our enemy is looking to the right direction. 13:26.870 --> 13:28.710 So right now what we have to do. 13:28.750 --> 13:31.070 Firstly, we need to set back y to zero. 13:31.310 --> 13:36.190 So this enemy one just going to flip towards to the left direction one more time. 13:36.190 --> 13:39.630 And after it we need to set that facing left to true. 13:39.630 --> 13:44.070 Because uh, if we flip our enemy to the left direction. 13:44.070 --> 13:48.310 So this enemy is just going to look towards to the left direction as you can see. 13:48.310 --> 13:49.150 So that's why. 13:49.190 --> 13:55.110 So we will simply copy this line of code by Ctrl C and let's paste it over here by Ctrl V. 13:55.310 --> 13:57.030 So we will set in the Y. 13:57.310 --> 13:59.510 So let's set back to zero F. 13:59.710 --> 14:05.150 And after flipping this enemy to the left direction we're going to set this facing left parameter to 14:05.190 --> 14:05.590 true. 14:05.590 --> 14:09.830 Because in this situation we're just going to look towards to the left direction. 14:09.990 --> 14:13.630 And now let's press down Ctrl S in order to save our script. 14:13.670 --> 14:15.750 And now let's move over to unity. 14:16.030 --> 14:23.950 So as soon as we're going to surpass our enemy one inch the x axis, then enemy one just looks to the 14:23.950 --> 14:24.710 right direction. 14:24.710 --> 14:30.590 But once our player is left direction from this enemy GameObject, then this enemy is just going to 14:30.590 --> 14:32.470 look towards to the left direction. 14:32.470 --> 14:38.030 Or you can simply say in the direction player is going enemy just gonna follow that. 14:38.070 --> 14:40.430 But or enemy just gonna flip that. 14:41.390 --> 14:45.310 So let's click on this play button in the top in order to play our game. 14:45.510 --> 14:49.510 And let's get inside attack range of this enemy one game object. 14:49.630 --> 14:55.110 So once we're gonna over here somewhere around here, then enemy is just going to look to the right 14:55.110 --> 14:55.870 direction. 14:55.870 --> 14:57.590 So let's take a look on this. 14:57.670 --> 15:04.150 So now if I surpass my player game object, as you can see, as soon as we doing this, enemy just looks 15:04.150 --> 15:05.510 to the right direction. 15:05.510 --> 15:08.400 But once we move to the left direction. 15:08.920 --> 15:10.640 We can see this enemy. 15:10.680 --> 15:14.520 It's now just a flip to the left direction as well. 15:14.520 --> 15:22.280 And if I just do it one more time, we can see now the the enemy just facing the direction in the direction 15:22.320 --> 15:23.520 player is going. 15:23.560 --> 15:30.680 Once our a our player in attack range, and if we just get outside of the attack range then this enemy 15:30.680 --> 15:31.840 just doing nothing. 15:31.880 --> 15:37.840 It just standing and then playing the idle animation clip over again and again. 15:37.840 --> 15:44.720 But once we get in attack range, it's just playing the attack arrow fire animation clip, and we can 15:44.720 --> 15:51.600 see that enemy one is now just looking towards or just flipping in the direction player is going, because 15:51.600 --> 15:58.120 we're doing inside this flip function, as you can see, and we only calling this flip function once 15:58.120 --> 16:02.200 our player get in attack range, as you can notice right over here. 16:02.720 --> 16:07.560 So I hope you get the idea that how you can do it and I'm gonna get out of play mode.
