WEBVTT 00:00.000 --> 00:00.920 What we need to do. 00:00.960 --> 00:03.560 We need to chase our player game object. 00:03.560 --> 00:09.040 So if I just go ahead and then click on this play button, you will see as soon as we collide with the 00:09.040 --> 00:11.360 circle enemy just gonna stops. 00:11.360 --> 00:18.200 So so what we want to do, we want to chase our player game object A with little bit high speed. 00:18.440 --> 00:19.480 So let's have a look. 00:19.720 --> 00:23.960 So if I get closer to it as you can see enemy stops moving. 00:24.080 --> 00:31.160 And if I move over to my console tab we can see a message just pop up says player in attack range instead 00:31.160 --> 00:32.760 of printing out message. 00:32.800 --> 00:35.680 Firstly we just want to get closer to this enemy. 00:35.920 --> 00:37.440 Sorry player game object. 00:37.600 --> 00:46.040 So we're gonna get a get closer to some certain distance, uh, from this uh, from our enemy game object. 00:46.200 --> 00:48.960 So let's get out of play mode and let's do that. 00:48.960 --> 00:54.440 So what we will do, we will open up this, uh, message by double click on it in our console tab. 00:54.600 --> 01:02.680 As you can see, we just printing out message, uh, message right over here says a player in attack 01:02.680 --> 01:03.320 range. 01:03.320 --> 01:09.280 So what we want to do right over here, instead of printing out message, we want to chase our player 01:09.320 --> 01:10.120 game object. 01:10.120 --> 01:17.280 So what we can simply do, we can go to top of our class and we can make a variable for our speed. 01:17.280 --> 01:22.120 So let's go to top of our animator script and let's create a serialized field. 01:22.400 --> 01:26.240 So let's create a serialized field private. 01:26.560 --> 01:28.520 And this will be float. 01:28.520 --> 01:31.440 And we can call this one something like Chase speed. 01:31.480 --> 01:33.280 So let's call it Chase speed. 01:33.280 --> 01:37.200 And by default I'm gonna give it something like four f. 01:37.200 --> 01:39.840 So we have given work speed to two. 01:40.160 --> 01:43.320 So that's why I'm just giving speed to four. 01:43.360 --> 01:45.640 As you can see right over here. 01:45.640 --> 01:51.360 Because we're gonna chase our player game object a little bit with a little bit high speed. 01:51.360 --> 01:52.880 So that is the reason. 01:52.880 --> 01:55.560 So now let's move over to this else condition. 01:55.560 --> 01:59.000 So else if we are in attack range. 01:59.240 --> 02:04.750 Attack range if our player in attack range now, what we're going to do, we're going to set the position. 02:04.750 --> 02:10.990 So transform dot position and transform dot position over here basically means current position of that 02:10.990 --> 02:12.430 enemy to game object. 02:12.430 --> 02:18.750 And we're going to set the position equal to vector two vector two dot move towards function. 02:18.750 --> 02:21.350 And this function basically it's going to move. 02:21.350 --> 02:27.230 So first thing it's going to take the current position where you are where you right now. 02:27.230 --> 02:31.110 And the second thing it's going to take the target position where you want to go. 02:31.230 --> 02:34.710 And the third argument it's going to take the speed with how much speed. 02:34.750 --> 02:37.350 You just want to move over to that point. 02:37.350 --> 02:42.750 So what we want to do as a first argument, we're going to type this transform dot position, which 02:42.750 --> 02:46.550 is current position of our enemy to game object. 02:46.550 --> 02:49.070 Second thing it's going to take the target position. 02:49.070 --> 02:52.310 So the target position will be our player position. 02:52.310 --> 02:55.310 So that's why we're going to type this player dot position. 02:55.550 --> 02:58.310 And the third argument it's going to take the speed. 02:58.310 --> 03:02.510 So we will pass our chase speed and make sure you multiply with that time. 03:02.550 --> 03:08.150 Dot delta time to make it frame rate independence and then close that off with semicolon. 03:08.150 --> 03:14.030 And if we save our script and move over to unity, you will see as soon as we're gonna collide with 03:14.030 --> 03:20.590 that circle, this enemy two GameObject just gonna chase our player GameObject with four unit of speed 03:20.590 --> 03:21.870 as we specified. 03:22.070 --> 03:23.670 So this Transform.position. 03:23.670 --> 03:29.830 Basically, we're setting the current position of that enemy to GameObject equal to this as you can 03:29.830 --> 03:30.310 notice. 03:30.590 --> 03:32.830 So now it should be work fine. 03:32.830 --> 03:34.270 So let's have a look on it. 03:34.590 --> 03:39.390 So as soon as we collide with that circle enemy enemy two GameObject. 03:39.390 --> 03:46.030 Just gonna chase our player GameObject with our Chase speed Chase speed amount. 03:46.030 --> 03:52.990 So just wait a moment to compile our script and once the compilation is done, we can check that out. 03:52.990 --> 03:57.790 So just wait a little moment and just wait a moment. 03:57.790 --> 04:04.790 And we also need to stop, uh, moving our enemy to game object once it gets some certain distance. 04:05.070 --> 04:09.270 Uh, to our player game object, we need to stop doing that. 04:09.270 --> 04:11.990 But before we do, let's, uh, let me show you. 04:11.990 --> 04:15.350 So it's going to take a few seconds to compile our script. 04:15.710 --> 04:21.550 I really apologize, it's just taking a little bit longer time since I have slow system. 04:21.550 --> 04:27.510 So now the compilation is done and I'm going to select my player game object and let's move it somewhere 04:27.510 --> 04:32.150 over here by selecting this move tool or this tool in the scene view. 04:32.470 --> 04:34.630 And let's check that out. 04:34.790 --> 04:40.590 And if I just go ahead and then click on this play button, you will see this uh animated game object 04:40.590 --> 04:45.270 just going to chase our player, uh, game object with little bit faster. 04:45.270 --> 04:48.630 And we can see underneath our enemy to skip the chase speed. 04:48.670 --> 04:54.150 By default we have given four, and now we can see as soon as we colliding with the circle, we can 04:54.150 --> 05:00.870 see, uh, by now that, uh, this, uh, enemy two game object just chasing our player, but the problem 05:00.870 --> 05:03.950 is that it's just pushing our player. 05:03.950 --> 05:05.670 So we need to stop doing that. 05:05.670 --> 05:10.230 Basically, we need to stop moving our this enemy to game object. 05:10.230 --> 05:15.950 Once it's get a some certain distance with our player game object. 05:15.950 --> 05:18.030 So we need to stop doing that. 05:18.030 --> 05:19.790 So let's get out of play mode for it. 05:19.830 --> 05:21.750 We will go over to script. 05:21.750 --> 05:27.310 So before we chase our player game object we just want to check the distance between them. 05:27.550 --> 05:32.630 So if it's some certain distance then this enemy need to stop chasing. 05:32.630 --> 05:36.950 And then this enemy to game object need to play the attack animation clip. 05:36.950 --> 05:38.070 So we're going to do that. 05:38.070 --> 05:41.630 So before we just we just want to check the distance between them. 05:41.950 --> 05:48.750 So we're going to create a retrieve distance parameter which is basically the distance we want to check 05:48.790 --> 05:53.230 between our this player game object and this enemy game object. 05:53.230 --> 05:57.430 So let's go to the top of our class and let's create another variable. 05:58.230 --> 06:02.180 And we can make it over here in attack check in title. 06:02.180 --> 06:03.660 So let's make it here. 06:03.860 --> 06:09.060 So we're going to make serialized field and that will be Private Float. 06:09.060 --> 06:12.380 And we can call this one something like retrieve distance. 06:12.380 --> 06:16.420 So I'm going to call it retrieve retrieve distance. 06:16.540 --> 06:20.380 And if I misspelling it I really apologize for it. 06:20.380 --> 06:24.700 And by default I'm going to say some set something like 2.5 F. 06:24.700 --> 06:26.860 And let's close that up with semicolon. 06:27.060 --> 06:29.540 So this will be our retrieve distance. 06:29.540 --> 06:31.860 So now let's move over to else condition. 06:31.860 --> 06:38.060 So before we chase our player game object we're going to check the distance between our player and enemy 06:38.060 --> 06:38.980 to game object. 06:38.980 --> 06:40.580 So we're going to use this if condition. 06:40.580 --> 06:43.220 Let's make first bracket and some curly brackets. 06:43.220 --> 06:45.100 So what we are going to do over here. 06:45.100 --> 06:48.660 We're going to check the distance between our player and the enemy. 06:48.700 --> 06:53.340 To check we're going to use this vector to dot distance distance function. 06:53.340 --> 06:55.740 And this vector two dot distance function. 06:55.740 --> 07:00.780 Just going to take two arguments two arguments basically two positions. 07:00.780 --> 07:03.780 And and it's going to compare between them. 07:03.780 --> 07:10.780 So first position I'm going to pass transform dot position which is basically means to a position enemy 07:10.780 --> 07:12.220 to current position. 07:12.220 --> 07:16.540 And the second position we want to check with our player position. 07:16.540 --> 07:18.980 So we're going to type this player dot position. 07:19.180 --> 07:26.220 And if the this and now if the distance between our enemy two and player position if it's greater than 07:26.220 --> 07:33.180 our retrieve distance if that is the case basically means that our this enemy two, this enemy two and 07:33.180 --> 07:40.020 this player game object either the distance between them if it's greater than retrieve distance means 07:40.060 --> 07:46.740 this player and this this enemy two game object still not yet closer to this player game object. 07:46.740 --> 07:50.660 So what we need to do, what we need to do in that moment. 07:50.660 --> 07:52.340 We need to chase our player. 07:52.340 --> 07:57.180 So that's why we're going to put this line of code inside this if condition. 07:57.180 --> 08:02.100 Because over here we're checking taking our enemy in our player game object? 08:02.140 --> 08:07.140 If the distance between is still greater than retrieved, distance means this. 08:07.300 --> 08:14.220 This enemy two game object is still not a get closer or not something like over here. 08:14.500 --> 08:17.740 Uh, so then what we're gonna do, we're going to chase. 08:17.740 --> 08:23.980 So that's why we will put this line of code by control X, and let's put it over here by control V. 08:24.140 --> 08:29.620 So we're checking if the distance between our enemy and this player, if it's greater than retrieve 08:29.620 --> 08:36.500 distance means our enemy two game object is still not, uh, too much closer to our player game object 08:36.540 --> 08:38.420 then what we are doing, we chasing. 08:38.420 --> 08:44.540 But let's suppose the distance between our player, this player game object, and this enemy two game 08:44.580 --> 08:46.660 object is now lesser than retrieved. 08:46.660 --> 08:49.940 Distance means it just gets too closer. 08:49.940 --> 08:54.580 So now what we have to do, we basically need to stop, uh, moving. 08:54.580 --> 09:01.850 So that's why in the else condition so else if our distance between our player and that enemy two game 09:01.890 --> 09:08.250 object is a it's lesser than retrieve distance means it's now close to our player game object. 09:08.250 --> 09:10.370 So it's what it's need to do. 09:10.410 --> 09:16.170 This enemy two game object need to attack on this player game object because it's now closer to this 09:16.170 --> 09:17.530 player game object. 09:17.530 --> 09:19.930 So for now we're gonna print out a message. 09:19.930 --> 09:23.330 So for that we're going to type Debug.log for printing out message. 09:23.370 --> 09:27.130 Say let's say something like play attack animation play. 09:27.330 --> 09:36.610 Let's say something like play enemy enemy to attack attack animation and attack animation. 09:36.610 --> 09:38.770 And let's close that up with semicolon. 09:38.770 --> 09:41.730 And we're going to press down Ctrl S to save our script. 09:41.930 --> 09:45.570 So firstly what we're doing we just using this else condition. 09:45.610 --> 09:52.610 Else if our player player game object just get in attack range then what we're doing we just moving. 09:52.610 --> 09:58.690 But before we are moving our enemy to to game object or basically chasing our player, we We're just 09:58.690 --> 10:00.490 checking the distance between them. 10:00.530 --> 10:04.890 If it is still greater than retrieve distance means it's not a. 10:05.130 --> 10:11.370 Our game object is still not get too much closer to player game object than we're chasing. 10:11.370 --> 10:17.490 And if it's too much close by now, then we're just printing out this message says play an enemy to 10:17.530 --> 10:18.930 Attack animation clip. 10:18.930 --> 10:19.570 Uh, sorry. 10:19.850 --> 10:22.090 Uh, we play enemy to attack. 10:22.090 --> 10:23.330 Animation message. 10:23.490 --> 10:24.410 Just gonna pop up. 10:24.410 --> 10:30.730 If the distance between our player and this enemy to game object is now too much close, or it's less 10:30.730 --> 10:36.050 than basically that retrieve distance and we can notice underneath our enemy to script. 10:36.050 --> 10:37.570 So now let's take that out. 10:37.570 --> 10:44.170 So if I just go add and then click on this play button in the top in order to play our uh, our game, 10:44.170 --> 10:47.810 you will see if uh, firstly our enemy to game object. 10:47.810 --> 10:50.650 Just gonna chase our player game object. 10:50.650 --> 10:55.130 But once it's just gonna get too much close basically, as you can see. 10:55.130 --> 11:01.490 So over here, if the distance, uh, basically the distance between our enemy two and this player is 11:01.490 --> 11:05.050 now lesser than retrieve distance a retrieve distance. 11:05.050 --> 11:08.970 And in that moment, what we are doing, we just simply printing out this message. 11:08.970 --> 11:13.450 As you can see, play enemy to attack animation instead of chasing. 11:13.490 --> 11:20.930 As you can see as basically our play, this enemy just stops moving once it's get too much close, uh, 11:21.170 --> 11:27.850 close or the retrieve distance is now lesser than between our this enemy two game object and this player 11:27.890 --> 11:28.770 game object. 11:28.770 --> 11:31.770 I want to increase the retrieve distance parameter. 11:31.930 --> 11:39.650 So I want to stop my enemy somewhere over here a little bit further away from this player game object. 11:39.650 --> 11:45.730 So that's why we can just increase the retrieve distance parameter parameter a little bit up. 11:45.730 --> 11:48.570 So I'm going to get out of play mode and retrieve distance. 11:48.610 --> 11:52.210 I'm going to choose something around four and change speed. 11:52.210 --> 11:54.770 I'm going to do something like 2.5. 11:55.610 --> 11:57.890 And the speed should be 1.2. 11:58.120 --> 12:02.400 I just want to move a little bit and I'm going to select my player game object. 12:02.400 --> 12:05.360 And let's move it over here somewhere here. 12:05.360 --> 12:09.360 And let's click on this play button in the top in order to play our game. 12:09.360 --> 12:12.400 So you will see as soon as this player game object. 12:12.560 --> 12:13.800 Sorry, sorry. 12:13.960 --> 12:20.560 As soon as this animator game object gets closer to this player game object, it's just gonna stop if 12:20.560 --> 12:23.280 the distance between is greater than retrieve. 12:23.400 --> 12:30.320 As you can see now, the now our animator game object stops moving because the distance between our 12:30.320 --> 12:35.200 player and this animator game object is lesser than that retrieve distance. 12:35.200 --> 12:42.120 But if the distance is greater than retrieve distance, basically the distance between our enemy to 12:42.160 --> 12:48.000 and this player, if it's still greater than retrieve distance, then we just chasing our player. 12:48.000 --> 12:54.240 But if the distance between our enemy to and the player if it's lesser than, lesser than than what 12:54.240 --> 13:00.600 we're doing in else condition else the distance between our this, uh, this player game object and 13:00.600 --> 13:04.360 this enemy two game object is now less than retrieved distance. 13:04.360 --> 13:10.600 Then we simply printing out this message in the console tab saying like playing enemy to attack animation. 13:11.040 --> 13:13.680 So I hope you get the idea that how you can do it. 13:13.680 --> 13:15.240 But we have a problem. 13:15.240 --> 13:22.240 If we jump over, we can see this enemy two game object, uh, trying to jump as well. 13:22.240 --> 13:23.920 So we need to stop doing. 13:23.960 --> 13:28.520 We want to, uh, chase our player game object only in the x axis. 13:28.520 --> 13:31.400 Or you can simply say in the horizontally. 13:31.440 --> 13:38.240 We don't want this enemy to game object to chase our player game object vertically or in the y axis. 13:38.240 --> 13:41.720 So what we're going to do we for that we're going to do the scripting. 13:41.720 --> 13:43.360 So let's get out of play mode. 13:43.360 --> 13:47.680 So we only want to chase our player game object in the x axis. 13:47.680 --> 13:50.440 Or you can simply say in the horizontally. 13:50.440 --> 13:55.880 So for that what we need to do we basically need to replace this player dot position, basically the 13:55.880 --> 13:58.160 target position where we want to go. 13:58.160 --> 13:59.960 So we need to replace this. 13:59.960 --> 14:01.680 So how we can replace this. 14:01.720 --> 14:04.440 For that we're going to create a vector two parameter. 14:04.440 --> 14:07.880 And we're going to call that parameter to something like a target. 14:07.880 --> 14:10.000 So let's create a vector two parameter. 14:10.000 --> 14:14.920 And we can call this one to something like target or target position. 14:14.920 --> 14:17.960 And we're going to set equal to a new vector two. 14:18.160 --> 14:22.400 And this vector two is just going to have x axis and y axis. 14:22.640 --> 14:28.760 So we only want to follow our player this player game object in the x axis or horizontally. 14:28.760 --> 14:32.120 So that's why we're going to replace this x with our player. 14:32.120 --> 14:35.600 So we will go to player dot position dot x. 14:35.640 --> 14:38.400 Basically we just accessing the player position. 14:38.600 --> 14:44.720 And in the in the y we don't want to follow our player game object at all in the vertically. 14:44.720 --> 14:47.280 Or you can simply say in the y axis. 14:47.280 --> 14:52.680 So that's why in the y what we're going to do, we're going to pass transform dot position dot y. 14:52.880 --> 14:59.160 It is basically means that current position of that enemy to game object itself in the y axis. 14:59.160 --> 15:00.560 So this target post. 15:00.560 --> 15:06.520 So basically this target post vector just gonna follow our player in the x axis only. 15:06.520 --> 15:10.840 As you can see we just replace x with our player dot position. 15:10.840 --> 15:15.440 Dot x means we're just gonna follow our player in the x axis only. 15:15.440 --> 15:18.320 And we're not doing at all in the y axis. 15:18.320 --> 15:20.520 So we just pass transform dot position. 15:20.520 --> 15:26.360 Dot y basically means that current position of this enemy to game object in the y axis. 15:26.360 --> 15:31.440 So this enemy two game object not gonna follow our player in the y axis. 15:31.440 --> 15:36.800 And now what we have to do, we need to replace this player dot position with this target pose. 15:36.800 --> 15:37.960 And this target pose. 15:37.960 --> 15:41.720 Vector is just gonna follow our player in the x axis only. 15:41.720 --> 15:44.760 And it's not gonna do in the y axis. 15:44.760 --> 15:48.440 So we're gonna replace this player dot position basically the target pose. 15:48.560 --> 15:53.000 So this vector2 dot move towards function as a second argument. 15:53.000 --> 15:54.720 It's gonna take the target pose. 15:54.720 --> 15:58.190 So we will pass our this pose which is our target post. 15:58.190 --> 16:00.190 So we're going to pass our target post. 16:00.190 --> 16:05.750 And we do know that this target post parameter, this vector to target post parameter. 16:05.750 --> 16:07.550 Just going to follow our player. 16:07.590 --> 16:11.230 Basically this player GameObject in the x axis only. 16:11.230 --> 16:14.830 And now we're going to press down Ctrl S in order to save our script. 16:14.830 --> 16:16.710 And now let's move over to unity. 16:16.870 --> 16:22.510 And by now we're not gonna be able to see or not gonna able to notice that thing. 16:22.830 --> 16:29.750 Basically, our enemy two GameObject not gonna follow our player GameObject in the Y axis or vertically. 16:29.790 --> 16:33.390 It's gonna follow in the x axis or horizontally. 16:33.390 --> 16:39.710 So that's why we just created that factor two parameter to just follow our player, uh, GameObject 16:39.710 --> 16:41.470 in the x axis only. 16:41.630 --> 16:47.190 And now if we go ahead and then hit this play button in the top, you will see this play this enemy 16:47.190 --> 16:48.030 two game object. 16:48.030 --> 16:54.590 By now it's gonna follow our player GameObject in the horizontally or in the x axis only. 16:54.590 --> 16:58.430 So let's have a look on this Is and we're going to jump over it. 16:58.470 --> 17:04.070 And we can see by now this enemy two game object is not jumping in. 17:04.110 --> 17:08.470 Basically, it's not moving in the y axis or vertically. 17:08.670 --> 17:16.710 And when once we get in attack basically closer to this enemy to game object or this enemy to game object, 17:16.750 --> 17:18.870 get closer to this player game object. 17:18.870 --> 17:25.790 As you can see, we just printing out a message in our console tab says play a play enemy to attack 17:25.790 --> 17:26.830 animation clip. 17:26.830 --> 17:32.990 But once we get a little bit away from this enemy two game object, we can see it's now changing because 17:32.990 --> 17:35.990 the position is greater than retrieved distance. 17:35.990 --> 17:42.670 But the position between our player and this enemy to if it's lesser than retrieved distance than what 17:42.670 --> 17:43.310 we're doing. 17:43.310 --> 17:49.190 So in that moment we just printing out the message in the console says play enemy to attack animation. 17:49.230 --> 17:53.390 Basically, we can simply assume that the distance is too much close. 17:53.390 --> 17:59.550 So that's why we just printing out this message instead of chasing our player game object, but the 17:59.550 --> 18:05.190 distance between our this enemy to and this player, if it's greater than retrieve distance basically 18:05.190 --> 18:13.710 means sorry and basically means the basically means that our player and this enemy to basically little 18:13.750 --> 18:15.030 bit further away. 18:15.030 --> 18:21.510 So in that moment, if I just cut this and then move over to my enemy to script what we can, what we're 18:21.510 --> 18:27.470 doing in that moment, we're just chasing our player game object in the x axis only, as you can see, 18:27.510 --> 18:34.030 if the distance between our enemy and this player game object, if it's greater than retrieve distance, 18:34.030 --> 18:39.910 basically means the distance between our player and this enemy to is not too much close yet. 18:39.910 --> 18:43.270 So that's why we chasing our player game object. 18:43.270 --> 18:51.150 But if it's too much close, basically the the distance between is now lesser than this retrieve distance 18:51.150 --> 18:52.190 so else condition. 18:52.190 --> 18:59.300 If the if our enemy to game object and the player game object is still to, uh, basically, uh, too 18:59.300 --> 19:00.060 much close. 19:00.100 --> 19:06.460 Then we're just printing out this message in the console, says play Enemy to attack animation message 19:06.460 --> 19:08.060 in our console tab. 19:08.060 --> 19:14.940 So I hope you get the idea that what we are just doing and what we have to do, uh, we now need to 19:14.940 --> 19:18.820 play the attack animation clip of this enemy two game object. 19:18.820 --> 19:25.060 Once it's get in attack range, and if the distance between is now too much close, then this enemy 19:25.060 --> 19:31.780 two game object need to play the attack to animation clip instead of playing the walking animation clip 19:31.780 --> 19:33.460 over again and again. 19:33.460 --> 19:38.500 So I'm gonna get out of play mode, and I hope you get the idea that how you can do it and make sure 19:38.500 --> 19:44.180 you select your enemy two game object and this player then go over to Inspector Overrides and then apply 19:44.180 --> 19:44.620 all. 19:44.620 --> 19:51.740 So if you change something around inside this enemy two script or anything or with any component, so 19:51.740 --> 19:57.060 the changes can just gonna be saved into this enemy two GameObject prefab as well.
