WEBVTT 00:00.050 --> 00:00.560 Hello guys. 00:00.560 --> 00:01.640 Welcome to this section. 00:01.640 --> 00:03.800 In this one we're going to develop enemies. 00:03.800 --> 00:08.240 And I think now development will go much faster because now we know a lot of things. 00:08.240 --> 00:10.550 We learned how to work with timers coroutines. 00:10.550 --> 00:14.600 We know how to move rigidbody with velocity, how to flip the character, all of that things. 00:14.600 --> 00:16.610 So now I'm going to show you how to do stuff. 00:16.610 --> 00:21.710 But things that I explained before I'm not going to, you know, tap on them as much as it was before. 00:21.710 --> 00:22.010 Yeah. 00:22.010 --> 00:23.630 So get ready for development. 00:23.630 --> 00:24.530 Let's go. 00:24.560 --> 00:26.930 We're going to go to Graphics Enemies. 00:26.930 --> 00:29.990 And here we have a bunch of enemies. 00:30.020 --> 00:33.710 We're not going to develop all of them, but we're going to develop a lot. 00:33.710 --> 00:38.900 And I want to start with simple I want to start with a mushroom enemy because it's quite simple. 00:38.900 --> 00:41.270 It just walks left and right and you can hit the enemy. 00:41.270 --> 00:41.840 That's it. 00:41.840 --> 00:46.550 We also need to keep in mind that we're going to develop not one enemy, but a bunch of them, and they're 00:46.550 --> 00:48.440 going to have similar functionality. 00:48.440 --> 00:53.930 Because of that, we better prepare some sort of inheritance that can be used by multiple enemies. 00:53.930 --> 01:00.680 As example, we have this mushroom that will run left and right with this animation over here. 01:00.860 --> 01:03.530 Also, we're going to have an enemy like um. 01:04.530 --> 01:12.630 Let's say rhino horns are going to run left and right, and we could type movement for both of them 01:12.630 --> 01:20.100 in two different scripts, but also we could make one movement function and then just use it on Rhino 01:20.100 --> 01:23.100 and on the mushroom getting me here. 01:23.100 --> 01:25.260 So we're going to develop a mushroom first. 01:25.260 --> 01:26.610 But we're going to do that. 01:26.880 --> 01:31.200 And we're going to keep in mind that we're going to need some of the script by other enemies. 01:31.200 --> 01:32.070 All right. 01:33.260 --> 01:35.600 As always, I offer you to start with simple. 01:35.600 --> 01:38.270 Let's set up controller and animations. 01:38.300 --> 01:41.030 I'm going to go to animations over here. 01:41.030 --> 01:44.030 Let's make a new folder for uh. 01:44.030 --> 01:45.560 Actually we don't need a folder for now. 01:45.560 --> 01:47.270 We can develop things here. 01:47.270 --> 01:49.280 Then we can arrange them into a folder. 01:49.610 --> 01:51.710 Let's do animator controller. 01:51.710 --> 01:55.010 This is going to be enemy mushroom. 01:56.090 --> 01:58.580 We type it together like so and we mushroom AC. 01:59.970 --> 02:02.430 Then we're going to do. 02:02.430 --> 02:02.970 Sorry. 02:02.970 --> 02:04.770 We need to go to graphics. 02:05.250 --> 02:06.360 Enemies. 02:06.360 --> 02:07.980 Let's find mushroom. 02:08.520 --> 02:11.640 Let's take the, uh, idle sprite place. 02:11.640 --> 02:14.250 It here is going to be enemy. 02:15.030 --> 02:15.990 Mushroom. 02:17.700 --> 02:19.710 We're going to give it a layer of, uh. 02:20.460 --> 02:22.140 Enemy just like that. 02:22.140 --> 02:23.730 So now it's going to be visible. 02:23.730 --> 02:24.780 Oh, we need to. 02:24.810 --> 02:25.050 Yeah. 02:25.050 --> 02:28.080 Let's take the sprites and make pixel per unit 16. 02:28.080 --> 02:28.920 Great. 02:28.920 --> 02:31.020 So now we have a mushroom enemy. 02:31.530 --> 02:34.500 We also want to give it a layer of the enemy. 02:34.920 --> 02:35.790 This is important. 02:35.790 --> 02:36.780 We're going to use it later on. 02:36.780 --> 02:38.400 So I'm going to do add layer. 02:38.400 --> 02:40.530 And over here we're going to do enemy. 02:40.530 --> 02:43.320 And since now we're using a couple of different layers. 02:43.320 --> 02:47.970 Let's select the player and give him layer of a player. 02:51.980 --> 02:52.670 Like so. 02:52.670 --> 02:58.880 So this one gonna have player and now this object only for the enemy. 02:58.880 --> 03:00.470 We're going to do enemy. 03:00.620 --> 03:01.730 Great. 03:02.340 --> 03:05.850 Now what do we need for this enemy animator controller? 03:05.850 --> 03:08.220 So we're going to drag it on the enemy like so. 03:08.250 --> 03:12.120 We also want to have a bunch of animations and let's prepare animations. 03:12.120 --> 03:15.960 Now when I do create assets animations. 03:15.960 --> 03:21.600 And over here I'm going to do Enemy mushroom and it's going to be idle. 03:23.560 --> 03:24.940 Let's go to graphics. 03:25.270 --> 03:26.290 Enemies. 03:27.380 --> 03:29.600 Mushroom idol. 03:31.670 --> 03:33.380 The sample array is going to be 20. 03:34.690 --> 03:37.390 Then we're going to need a new clip. 03:37.390 --> 03:39.670 Enemy mushroom. 03:39.730 --> 03:40.210 Uh. 03:40.990 --> 03:41.920 Move. 03:42.640 --> 03:44.530 You're going to have this run animation. 03:46.100 --> 03:47.330 Can I place them here? 03:47.330 --> 03:49.190 Sample rate 20. 03:49.670 --> 03:53.150 Let me make it a bit smaller and I'm going to stretch the window. 03:53.150 --> 03:54.860 So this is the run animation. 03:54.860 --> 03:58.160 And also we're going to have a hit animation. 03:58.160 --> 04:01.070 So we're going to do enemy. 04:01.810 --> 04:02.950 Mushroom. 04:03.070 --> 04:04.030 Let's just call it hit. 04:04.030 --> 04:05.320 Enemy mushroom hit. 04:07.180 --> 04:09.430 Can I take these sprites and place them here? 04:09.430 --> 04:11.470 Sample rate 20. 04:11.500 --> 04:12.460 Nice. 04:12.490 --> 04:14.530 Now let's go to animator of this one. 04:14.530 --> 04:20.080 And for the movement and idle I think I'm going to use the blend tree would be the easiest one right. 04:20.230 --> 04:24.280 Uh because we're going to use velocity rigid body velocity for this enemy. 04:24.280 --> 04:29.260 So let's make a blend tree and name it as move idle. 04:29.260 --> 04:31.270 And that's what we did for the player. 04:31.270 --> 04:32.350 Oh I hate this bug. 04:32.350 --> 04:33.700 This happens all the time. 04:33.700 --> 04:35.380 Move idle. 04:35.380 --> 04:39.280 Uh, I need to restart unity so I can rename this blend tree. 04:39.280 --> 04:40.810 Just give me a minute. 04:41.810 --> 04:43.670 Okay, let's try again. 04:44.670 --> 04:45.840 Idle move. 04:46.560 --> 04:47.220 Good. 04:47.220 --> 04:53.880 Now inside we're going to have two motions one two and let's do three. 04:54.030 --> 05:00.360 Automate threshold and check is going to be mushroom I cannot see anything. 05:00.360 --> 05:01.740 Mushroom move. 05:04.370 --> 05:06.860 Mushroom idol and. 05:07.810 --> 05:09.490 Mushroom move. 05:09.490 --> 05:10.810 I'm going to extend it like so. 05:10.810 --> 05:15.790 So you can see the names you're going to have minus one zero one. 05:15.790 --> 05:18.190 Now if you open preview over here. 05:18.870 --> 05:20.430 And click play. 05:20.460 --> 05:20.970 Oh. 05:21.000 --> 05:21.540 What's up? 05:21.540 --> 05:22.620 Why it's not available. 05:28.020 --> 05:28.650 Yeah. 05:28.770 --> 05:30.330 We need to select it again okay. 05:30.330 --> 05:33.600 So he's moving on the zero. 05:33.600 --> 05:34.890 He's standing. 05:35.910 --> 05:37.320 Then he's moving again. 05:37.470 --> 05:38.340 Cool. 05:38.340 --> 05:39.510 Very cool. 05:39.540 --> 05:42.390 Now let's rename this to x velocity. 05:42.390 --> 05:46.050 And this is the parameter we're going to control on the mushroom. 05:46.140 --> 05:48.810 Now let's go to the base layer. 05:49.560 --> 05:51.570 Take this enemy mushroom hit. 05:51.570 --> 05:53.100 This should be a default. 05:53.100 --> 05:56.640 Then we're going to transfer to enemy mushroom with a trigger. 05:58.720 --> 06:00.700 Trigger hit just like that. 06:00.700 --> 06:01.240 Why not? 06:02.650 --> 06:03.430 Trigger. 06:03.430 --> 06:06.970 Hit exit time and check transition duration zero. 06:06.970 --> 06:12.190 And I suppose we're going to destroy the object or make him fall after we hit the enemy. 06:12.190 --> 06:15.970 This is how it's going to be on a preview of these assets. 06:15.970 --> 06:18.760 You actually can see how enemies are dying. 06:18.760 --> 06:20.440 Let me just quickly find it over here. 06:20.440 --> 06:24.520 You can see when we jump in on the enemy, they sort of fallen off the level. 06:24.520 --> 06:27.760 They do a bit of a rotation, they lose in Collider and they just fall in. 06:27.760 --> 06:29.650 So probably that's what we can do. 06:29.650 --> 06:30.250 Let's see. 06:30.250 --> 06:34.420 Maybe we'll take a different approach because we already know how to make objects fall off the level. 06:34.420 --> 06:34.870 Right. 06:34.870 --> 06:36.610 The falling platform does that. 06:36.610 --> 06:39.160 We just disable colliders and it falls off the level. 06:39.160 --> 06:41.590 So it's not really different from what we've seen just now. 06:41.590 --> 06:42.310 Okay. 06:42.310 --> 06:45.040 So now we need a mushroom script. 06:45.740 --> 06:47.270 An anime script. 06:47.270 --> 06:51.560 Let's go to scripts and I'm going to make C sharp script. 06:51.800 --> 06:52.730 Enemy. 06:54.020 --> 06:56.210 Then I'm going to make C sharp script. 06:59.400 --> 07:01.470 Enemy mushroom. 07:03.840 --> 07:05.550 Here we have enemy mushroom. 07:05.550 --> 07:07.260 Why am I doing it like that? 07:07.260 --> 07:13.800 Well, we're going to put enemy mushroom on the enemy mushroom, and we're going to do the common thing 07:13.800 --> 07:14.850 on the enemy script. 07:14.850 --> 07:17.520 And enemy mushroom will inherit from the enemy. 07:17.520 --> 07:18.870 Let me show you the example. 07:18.870 --> 07:20.700 Let's do inheritance from the enemy. 07:20.700 --> 07:23.850 And we know that most of the enemies are going to have a movement speed. 07:23.850 --> 07:24.360 Right? 07:24.360 --> 07:27.870 I'm going to close all by this and I'm going to find enemy script. 07:29.310 --> 07:35.280 So if most of the enemies have movement speed, then we don't need to make movement speed variable on 07:35.280 --> 07:36.240 each new enemy. 07:36.240 --> 07:38.700 We can do it only once by making it here. 07:38.700 --> 07:40.530 Let's make serialize field. 07:41.100 --> 07:42.540 Uh, protected float. 07:42.540 --> 07:44.010 Move speed. 07:45.100 --> 07:46.300 Now let's save this. 07:46.300 --> 07:47.920 Let's go back to unity. 07:49.440 --> 07:52.710 And we can see that move speed is there for the enemy mushroom. 07:52.710 --> 07:58.770 So now further on when we create new enemy and we need some bunch of parameters that are common between 07:58.770 --> 08:03.090 different enemies, we can easily just make it on the enemy script and use it by others. 08:03.210 --> 08:07.950 Let's go ahead and keep development of the enemy mushroom through the enemy script. 08:07.950 --> 08:12.150 We know that other enemies, not only enemy mushroom, going to have an animator. 08:12.150 --> 08:18.960 So let's do protected animator anim, and probably most of them going to have rigid body. 08:18.960 --> 08:22.170 So let's do protected rigid body RB. 08:22.860 --> 08:28.110 And then we're going to open our wake that we can override because later on we might need to override 08:28.110 --> 08:28.500 our wake. 08:28.500 --> 08:31.560 So I'm going to do protected virtual void awake. 08:31.590 --> 08:35.580 This will allow me to override the method on the enemy mushroom. 08:35.580 --> 08:38.190 As example we can go to enemy mushroom. 08:38.190 --> 08:41.910 And here we can just type override awake. 08:43.010 --> 08:49.130 And this will be a new awake that has functionality of the enemies awake. 08:50.980 --> 08:51.790 Cool. 08:51.850 --> 08:53.770 Now let's go to enemy again. 08:53.770 --> 08:59.740 And over here we're going to do Anim Getcomponent of the animator and RB Getcomponent of Rigidbody. 08:59.980 --> 09:01.030 Very nice. 09:01.060 --> 09:03.040 Now let's say we want to move the enemy. 09:03.040 --> 09:08.860 We could make one script that other enemies would use for the movement, but we are not sure yet how 09:08.860 --> 09:10.420 other enemy is going to act. 09:10.420 --> 09:13.570 If we're going to need to use script on those enemies as well. 09:13.570 --> 09:18.970 That's why for now, I'm going to do handle movement on the enemy mushroom only I'm going to do private, 09:19.090 --> 09:21.940 uh, void handle movement. 09:21.940 --> 09:24.820 And in the handle movement we're going to do RB velocity. 09:24.820 --> 09:30.670 And as you can see it is available to this script because we have it as protected on the enemy over 09:30.670 --> 09:31.300 here. 09:31.990 --> 09:34.780 So velocity equals to new vector two. 09:34.780 --> 09:36.430 And here we have move speed. 09:36.430 --> 09:39.010 And then we're going to do rb velocity dot y. 09:39.010 --> 09:41.500 It also would be nice to know facing direction. 09:41.500 --> 09:44.980 So we can define where enemy should move left or right. 09:44.980 --> 09:47.080 So let's go to enemy over here. 09:47.080 --> 09:53.380 And let's make a protected int facing direction. 09:53.380 --> 09:58.390 And if you remember our mushroom is facing to the left as well as most of the enemies. 09:58.390 --> 10:00.550 So I'm going to make it minus one by default. 10:00.550 --> 10:06.340 Let's save this then on the enemy mushroom we can do multiply by facing direction. 10:07.630 --> 10:09.460 Now we need an update. 10:09.520 --> 10:10.420 Update. 10:10.420 --> 10:11.920 Handle movement. 10:12.750 --> 10:13.650 Cool. 10:13.650 --> 10:15.360 Now let's go. 10:15.360 --> 10:18.300 Uh, actually, we need to update the animations as well. 10:18.300 --> 10:19.260 Would be nice. 10:19.260 --> 10:27.030 So I'm going to do anim set float of x velocity to the RB velocity dot x. 10:28.190 --> 10:29.390 Very nice. 10:29.420 --> 10:31.250 Let's go back to unity. 10:31.280 --> 10:35.870 This enemy needs to have a collider so we can give it different colliders. 10:35.870 --> 10:37.160 Let's try. 10:37.730 --> 10:39.800 Let's try Box Collider for now. 10:40.850 --> 10:42.410 And we're going to just. 10:43.930 --> 10:48.790 Decrease it to the size of this maybe is going to be a body collider. 10:48.790 --> 10:51.700 We're going to use it to detect collision around the mushroom. 10:51.700 --> 10:55.780 So he will not fall through the ground or he will not pass by walls. 10:55.780 --> 10:57.700 And we also need a rigid body on this one. 10:57.700 --> 10:59.680 So I'm going to do rigid body 2D. 11:00.710 --> 11:02.990 Let's do interpolate collision detection. 11:02.990 --> 11:04.100 Continuous. 11:04.700 --> 11:06.770 Now we can go to play mode. 11:07.100 --> 11:08.510 He's going to stand there. 11:09.940 --> 11:11.170 In the idle. 11:11.320 --> 11:12.490 Oh, what is that? 11:13.290 --> 11:16.080 Variable of a waypoint have not been assigned. 11:16.810 --> 11:17.290 Over here. 11:17.290 --> 11:18.670 We need to remove none. 11:23.360 --> 11:24.950 Okay, so now mushroom stands there. 11:24.950 --> 11:28.700 I can give him movespeed of two and he's moving to the left. 11:29.300 --> 11:30.170 A very funny guy. 11:30.170 --> 11:30.770 I like it. 11:30.770 --> 11:34.280 So he walks like that and then falls down. 11:34.280 --> 11:38.780 What do we need now is to detect the ground in front of the mushroom. 11:38.780 --> 11:46.220 And then if there is no ground in front of him like so, then he'll be like, okay, I need to go to 11:46.220 --> 11:47.930 another side and he's going to flip. 11:47.930 --> 11:52.430 So if that's what we need, then we need collision detection on the mushroom. 11:52.430 --> 11:56.000 And we need a flip method just like we had on the player. 11:56.960 --> 12:02.060 Also, I think that lots of enemies are going to need a collision detection probably. 12:02.060 --> 12:05.120 So I'm going to make a header over here. 12:06.090 --> 12:06.750 Header. 12:06.780 --> 12:08.790 Basic collision. 12:08.790 --> 12:10.260 Let's do serialize field. 12:10.740 --> 12:11.880 Protected. 12:12.850 --> 12:17.860 Float and it's going to be, uh, ground check distance. 12:17.860 --> 12:19.990 And now it's going to be 1.1. 12:19.990 --> 12:21.700 So let's do it as a default value. 12:21.700 --> 12:26.950 Then we need serialize field protected float wall check distance. 12:27.280 --> 12:29.140 Uh let's do 0.7 F by default. 12:29.140 --> 12:30.850 But we can always adjust. 12:30.880 --> 12:32.350 We're also going to need a layer. 12:32.350 --> 12:37.750 So protected layer mask what is ground. 12:37.750 --> 12:40.930 And we cannot check the ground under the mushroom. 12:40.930 --> 12:43.570 We need to make ground check in front of him. 12:43.570 --> 12:47.020 Because of that we're going to have serialized field protected transform. 12:47.860 --> 12:50.590 Uh, ground check. 12:50.710 --> 12:51.700 Just like that. 12:52.360 --> 12:55.030 And I think that's good for now. 12:55.030 --> 12:57.010 Now let's go ahead and make a method. 12:57.010 --> 12:59.110 And I feel a little bit lazy. 12:59.110 --> 13:01.780 So I'm going to go to the player script. 13:03.080 --> 13:04.430 All the way down. 13:05.410 --> 13:07.180 We have this handle collision. 13:07.180 --> 13:09.790 We have our flip methods. 13:09.790 --> 13:11.140 So we're going to take them. 13:11.140 --> 13:14.230 Let's take these three copy it. 13:14.230 --> 13:16.720 Go to enemy face them in. 13:17.230 --> 13:20.230 Also we need this handle collision method. 13:20.230 --> 13:21.640 Let's copy this. 13:21.670 --> 13:25.660 Go to enemy and paste it over here. 13:25.660 --> 13:28.570 Now we need to fix this bunch of errors and it's going to be good. 13:28.570 --> 13:30.850 We have a boolean that we need to create. 13:30.850 --> 13:35.530 Let's go and make protected bool facing right. 13:35.530 --> 13:39.550 And it's going to be false by default because we know mushroom is facing left. 13:40.860 --> 13:44.460 Now for these booleans over here we need. 13:46.270 --> 13:52.030 Private and let's do protected protected bull is wall detected. 13:52.030 --> 13:56.440 And also I want to have protected bull is ground detected. 13:57.460 --> 13:58.900 We can go down. 14:01.190 --> 14:05.390 And over here we're going to type is ground detected. 14:06.790 --> 14:07.660 Nice. 14:07.660 --> 14:09.370 Now for the ground check. 14:09.370 --> 14:13.240 Instead of transform, we're going to use ground check position. 14:14.130 --> 14:14.910 Very good. 14:14.910 --> 14:19.050 Also, we need to change it here for the gizmos ground check position. 14:20.580 --> 14:22.170 Ground check position. 14:22.950 --> 14:24.240 Ground check position. 14:25.580 --> 14:26.060 Cool. 14:26.060 --> 14:30.110 So now we have collision check and gizmos check on the enemy. 14:30.230 --> 14:36.710 This is the handle flip method, which will act a bit differently according to the enemy we have. 14:36.710 --> 14:38.330 Let me quickly explain. 14:38.720 --> 14:45.590 If a mushroom is moving to the left, then probably we have to just adjust, you know, like set, handle, 14:45.590 --> 14:48.830 flip according to the velocity of the rigid body on the x. 14:48.830 --> 14:52.730 But there is such enemy as a, uh, bat. 14:53.330 --> 14:54.110 As example. 14:54.110 --> 14:54.440 Yeah. 14:54.440 --> 14:56.420 Graphics enemies bet. 14:56.960 --> 15:02.180 And this enemy will fly towards the player when it detects the player. 15:02.180 --> 15:05.210 And here we're not going to have our base velocity. 15:05.210 --> 15:08.930 We're probably going to use move towards, just like we did with the trap. 15:08.930 --> 15:15.980 So for that we cannot use our base velocity, but we can use position of the player to flip the enemy 15:15.980 --> 15:17.720 to know where he needs to face. 15:17.720 --> 15:21.110 So as you can see, it can be different for different enemies. 15:21.110 --> 15:27.440 Because of that, I'm going to pass a variable over here, float x value and we're going to use x value. 15:28.320 --> 15:28.800 Here. 15:28.800 --> 15:32.520 So now this method is flexible can be used with any x we have. 15:32.520 --> 15:33.300 Cool. 15:34.580 --> 15:35.810 We have a lot. 15:35.810 --> 15:36.800 Um. 15:39.280 --> 15:41.050 I'm going to go to enemy mushroom. 15:41.410 --> 15:44.200 I'm going to call handle collision over here. 15:44.850 --> 15:45.810 Oh, it's not available. 15:45.810 --> 15:48.000 Okay, let's go to enemy. 15:48.240 --> 15:51.870 Make this as protected virtual void. 15:52.950 --> 15:54.690 Gizmo is going to work like that, I think. 15:54.690 --> 15:55.800 So we don't need it. 15:55.800 --> 16:03.480 And the flip can be as protected virtual void and better make it, uh, for the flip as well. 16:04.730 --> 16:07.100 Nice nice nice nice. 16:07.100 --> 16:09.110 So so far nothing new. 16:09.110 --> 16:10.910 We had this functionality on the player. 16:10.910 --> 16:17.120 We know how it works and just on the enemies script, so it can be used by many enemies and how it can 16:17.120 --> 16:18.380 be used by many enemies. 16:18.380 --> 16:20.270 I'm going to show you on the enemy mushroom. 16:20.270 --> 16:22.670 So now we can type here handle collision. 16:24.660 --> 16:31.680 And now in the update we can check if no is ground detected means we do not have anything in front of 16:31.680 --> 16:36.390 the mushroom, and it's time to flip the mushroom so he can walk to another side. 16:36.390 --> 16:38.130 Let's do flip over here. 16:38.430 --> 16:40.140 Now I'm going to save it. 16:40.500 --> 16:41.940 Go back to unity. 16:43.360 --> 16:43.900 Over here. 16:43.900 --> 16:47.260 We need to make an empty transform for the mushroom. 16:47.290 --> 16:50.260 Let's do create empty ground. 16:50.260 --> 16:51.160 Check. 16:51.370 --> 16:53.830 And I'm going to assign it over here. 16:53.830 --> 16:56.020 And also we need to choose what is ground. 16:57.790 --> 16:58.480 Nice. 16:58.480 --> 17:01.030 Now the ground check is far enough. 17:01.030 --> 17:01.450 It's okay. 17:01.450 --> 17:04.420 So 1.1 was good for the wall check. 17:06.040 --> 17:09.850 Yeah, point nine will be okay. 17:09.850 --> 17:14.860 Now, if I'm not wrong and I'm pretty sure I'm right, we need to hit the play button. 17:14.860 --> 17:20.050 Mushroom will walk up to here, and then he'll decide to flip back because there is no ground in front 17:20.050 --> 17:20.560 of him. 17:21.500 --> 17:26.480 We only need to take this ground check and move it forward like so. 17:26.810 --> 17:28.880 Just so we're doing check in front of him. 17:28.880 --> 17:30.380 Let's go. 17:30.380 --> 17:32.210 And mushroom is there. 17:32.210 --> 17:35.810 And then he's like haha and walks back. 17:35.810 --> 17:36.710 Perfect. 17:36.710 --> 17:39.920 Now we want to flip the mushroom when he's facing the wall. 17:40.310 --> 17:42.650 Let's go back to the script. 17:43.310 --> 17:47.030 And over here we're going to do or is well detected. 17:47.210 --> 17:48.230 Nice. 17:48.230 --> 17:51.710 Now you're going to flip, uh, when he faces the wall as well. 17:51.860 --> 17:56.690 Then next thing I want to do is to give him a bit of the idle time. 17:56.690 --> 18:02.630 I want him to walk up to the wall or ledge and wait for a while. 18:02.630 --> 18:04.790 Let me quickly check the flip with the wall. 18:07.240 --> 18:07.600 Yeah. 18:07.600 --> 18:08.350 Good. 18:11.340 --> 18:15.390 So to add the idle time, we're going to do something that we did before. 18:15.390 --> 18:17.820 We're going to use time dot delta time and a timer. 18:17.850 --> 18:20.100 Let me quickly explain how it's going to work. 18:20.100 --> 18:23.250 And I think we might need this idle time on other enemies. 18:23.250 --> 18:31.200 So I'm going to go ahead here and make serialized field private or sorry, let's do protected float 18:31.200 --> 18:32.730 idle time. 18:32.730 --> 18:33.930 And. 18:34.720 --> 18:39.730 And let's do protected float, idle timer. 18:40.060 --> 18:42.610 And it's going to be very easy to make a mistake like that. 18:42.730 --> 18:47.740 Let's do, uh, let's do idle timer and idle duration. 18:48.360 --> 18:53.700 Although I like idle time better, we need to be sure we don't make mistake in the future. 18:53.700 --> 18:54.180 Okay. 18:54.300 --> 18:57.720 Let me maybe do serialize field so we can see how it's working. 18:57.720 --> 18:58.320 Okay. 18:58.320 --> 19:00.780 And I'm going to just. 19:02.390 --> 19:05.480 Let's do protected virtual update. 19:06.360 --> 19:07.170 Avoid. 19:07.170 --> 19:07.890 Sorry. 19:09.380 --> 19:10.700 Void update. 19:11.060 --> 19:12.230 What's up man? 19:13.070 --> 19:13.550 Yeah. 19:13.550 --> 19:14.210 Okay. 19:14.390 --> 19:15.230 Update. 19:15.530 --> 19:16.460 And. 19:17.400 --> 19:18.720 On the enemy mushroom. 19:18.720 --> 19:22.200 Instead of doing private void, we can do override update. 19:22.230 --> 19:27.390 Protected override okay, so now this is overriding the update we have here. 19:27.390 --> 19:30.690 But because we did not type base it's not going to work. 19:30.690 --> 19:33.240 We just need to type base update. 19:33.240 --> 19:37.200 Now it's going to have functionality of the base update from the enemy. 19:37.200 --> 19:42.630 And in the base update we can do idle timer minus equals time dot delta time. 19:42.630 --> 19:45.120 So we're going to decrease the value all the time. 19:45.210 --> 19:47.700 Let's save this. 19:48.150 --> 19:50.550 Let's go back to uh unity. 19:50.550 --> 19:52.140 And I'm going to show you what we're going to do. 19:54.030 --> 19:56.400 So you can see idle timer is decreasing. 19:56.430 --> 20:00.840 Once we set value to positive let's say duration will be two. 20:00.840 --> 20:02.730 And we're going to give here two. 20:02.880 --> 20:04.950 This is the time you're going to stand on the ground. 20:04.950 --> 20:06.000 We're not going to walk. 20:06.000 --> 20:09.240 And then once it's less than zero then we can walk again. 20:09.240 --> 20:10.320 That's the goal. 20:10.680 --> 20:11.910 How are we going to achieve this. 20:11.910 --> 20:17.820 Let's go to enemy mushroom and we can override the flip method. 20:18.210 --> 20:20.310 Override flip. 20:20.310 --> 20:27.120 And once we flip we're going to do idle timer equals to idle duration. 20:27.120 --> 20:33.420 So every time we flip the character we're also going to uh set idle timer to idle duration. 20:33.420 --> 20:37.440 If you would like you can just open curly brackets and do it here. 20:37.440 --> 20:38.670 That would work as well. 20:41.100 --> 20:42.630 Probably makes more sense. 20:44.970 --> 20:48.810 And then we need to stop movement. 20:48.810 --> 20:55.830 If idle timer is, uh, less than zero, we can do that simply by going to handle movement and type. 20:55.830 --> 20:59.880 If idle timer is less than zero, then return. 20:59.880 --> 21:05.430 Uh, so every time we flip, we're going to set idle time and mushroom going to stand and wait. 21:05.430 --> 21:08.100 Let's give it idle duration of 1.5. 21:08.100 --> 21:09.300 And let's see this. 21:10.130 --> 21:11.810 You're gonna walk there. 21:13.270 --> 21:14.440 Come on, man, why? 21:14.440 --> 21:15.460 He's not working. 21:15.490 --> 21:16.600 Did I make a mistake? 21:16.600 --> 21:18.160 I think I did make a mistake. 21:29.250 --> 21:29.610 Yeah. 21:29.610 --> 21:32.400 If idle time are bigger than zero, then we return. 21:32.400 --> 21:34.680 So if we still have idle time, we cannot walk. 21:34.710 --> 21:36.390 Yes, this is how it should be. 21:36.390 --> 21:37.350 I'm sorry. 21:37.470 --> 21:39.450 This is how it should be. 21:39.930 --> 21:41.100 Let's go. 21:45.990 --> 21:53.100 And he works there and then he's like flipping and waiting for a while, then walks back. 21:53.880 --> 21:55.860 Also, I've seen a bit of a slide. 21:55.860 --> 21:57.390 I didn't really like that. 21:59.210 --> 22:01.370 Uh, let me make his speed faster. 22:02.770 --> 22:06.760 And he's like, well, that's not what we need. 22:07.030 --> 22:09.460 Uh, let's go to enemy mushroom. 22:09.940 --> 22:11.260 And I think. 22:11.710 --> 22:17.320 We can do RB velocity equals to new vector or just vector zero vector zero. 22:17.320 --> 22:21.010 So we're going to stop his velocity once he is leaping. 22:21.280 --> 22:22.750 Yeah that would be a bit better. 22:22.750 --> 22:26.200 Also, let's apply this only if ground is detected. 22:29.270 --> 22:32.750 And that would remove Jitterin when he's falling off the ground. 22:33.050 --> 22:34.250 Let's go back. 22:35.010 --> 22:37.890 Let's say he moves faster and then he is like stopping. 22:38.840 --> 22:39.890 Okay. 22:42.290 --> 22:43.430 Very good. 22:45.760 --> 22:46.330 Nice. 22:46.330 --> 22:51.070 I'm going to give it smooth speed of, uh, two because I like how it worked. 22:51.430 --> 22:52.630 Let me check something. 22:52.630 --> 22:54.850 I want to see if he's in the air. 22:54.850 --> 22:55.900 What's he going to do? 22:57.020 --> 22:59.210 For any reason he could be in the air. 22:59.840 --> 23:01.310 He's flipping endlessly. 23:02.470 --> 23:03.910 Okay. 23:04.210 --> 23:05.710 How could we stop this? 23:05.920 --> 23:08.500 Well, just to be sure, let's do this. 23:08.500 --> 23:16.330 We're gonna go to enemy and rename this to Ground forward detected or ground in front. 23:16.510 --> 23:20.650 Um, is in front detected. 23:20.650 --> 23:24.640 And then we're going to make one more check for the ground that it's going to be two different checks. 23:24.640 --> 23:27.310 Private ball is grounded. 23:27.310 --> 23:31.540 Then we're going to go back to the handle. 23:31.540 --> 23:35.080 Collision and do is grounded equals to physics. 23:37.410 --> 23:38.940 2D raycast. 23:40.790 --> 23:45.770 And this one can be done from a transform position vector two dot down. 23:47.090 --> 23:49.880 Uh, ground check distance as well, I think. 23:49.880 --> 23:50.930 What is ground? 23:50.930 --> 23:51.770 Nice. 23:51.770 --> 23:53.840 And then we're going to need the gizmos. 23:53.840 --> 23:56.930 So I'm going to just duplicate this line of code. 23:58.230 --> 24:00.270 Change it to a transform position. 24:00.270 --> 24:03.240 So we basically add in one more collision check. 24:03.240 --> 24:07.320 And if character is not grounded, he will not be able to flip. 24:10.080 --> 24:10.740 Yeah. 24:10.740 --> 24:12.150 This is what I want to do. 24:12.650 --> 24:15.170 So everything works the same over here. 24:15.320 --> 24:17.810 Except that over here. 24:22.120 --> 24:22.390 How? 24:22.390 --> 24:24.400 Maybe even here I can do. 24:24.970 --> 24:25.180 Wait. 24:25.480 --> 24:26.740 Let's do if. 24:27.450 --> 24:30.270 He is grounded equals to false, then return. 24:31.000 --> 24:31.630 Yeah. 24:33.010 --> 24:34.960 And then we do need it over here. 24:36.230 --> 24:37.700 But now we're going to check how it's working. 24:37.700 --> 24:38.600 Then I'm going to take a look. 24:38.600 --> 24:42.920 If we clean this up and we're going to move to the next video, and I know it took a bit longer than 24:42.920 --> 24:47.600 it like we wish it would take, but we did set up for other enemies. 24:47.600 --> 24:49.730 So it's good. 24:49.760 --> 24:50.660 Now he's walking. 24:50.660 --> 24:53.780 They're leaping, going back. 24:53.780 --> 24:58.670 If I take him and pull him into the air, he's going to just fall. 24:58.700 --> 24:59.240 Cool. 24:59.240 --> 25:00.170 This is what we need. 25:00.170 --> 25:00.740 All right? 25:00.740 --> 25:01.340 I like it. 25:01.340 --> 25:01.760 Now. 25:01.760 --> 25:04.520 If you would like, you could make him like. 25:04.520 --> 25:05.180 You would make. 25:05.210 --> 25:09.080 You could make a possibility of a trampoline bounce in the enemies. 25:09.560 --> 25:11.660 But that would take another ten minutes. 25:11.660 --> 25:13.730 And I want to spend time on other enemies. 25:13.730 --> 25:18.890 Maybe we can do this with a polish, but if you want to do it yourself, you basically make a method 25:18.890 --> 25:21.710 for the enemy mushroom, same as we did for the player. 25:21.860 --> 25:22.820 Like. 25:24.180 --> 25:25.080 This one. 25:25.500 --> 25:26.520 Push method. 25:26.520 --> 25:27.480 Where is the push? 25:29.730 --> 25:30.150 Push. 25:30.150 --> 25:33.900 So you take this functionality, give it to the enemy mushroom. 25:33.900 --> 25:36.330 Then on a trampoline you detect if. 25:38.740 --> 25:43.960 Player or enemy walked into the trampoline and then just call the method and bounce. 25:43.960 --> 25:46.180 The mushroom would be fun I'm sure. 25:46.360 --> 25:48.610 Anyway, this is a great job! 25:48.610 --> 25:50.080 Thank you so much for paying attention. 25:50.080 --> 25:51.640 Oh, let me hide this timer. 25:54.970 --> 25:56.020 We don't need serialize field. 25:56.020 --> 25:57.670 Now we know how it works. 25:57.670 --> 25:59.110 And on enemy mushroom. 25:59.110 --> 25:59.710 Give me a second. 25:59.710 --> 26:01.540 I'll see if we can clean this up. 26:02.430 --> 26:02.760 Okay. 26:02.760 --> 26:04.230 We don't need a wake. 26:12.170 --> 26:22.940 And I think we can we can remove this from here, extract it as a extract method and they'll turn around. 26:22.940 --> 26:25.970 That's what I wanted to call and I'll do if. 26:26.890 --> 26:27.220 Uh. 26:27.940 --> 26:29.230 He's grounded. 26:29.350 --> 26:31.720 Poles then return. 26:32.840 --> 26:35.000 Or maybe let's just do if is grounded. 26:36.660 --> 26:38.100 Then handle turnaround. 26:38.100 --> 26:38.910 Okay? 26:39.000 --> 26:42.060 Yeah, this is a bit cleaner, I like it. 26:42.060 --> 26:45.270 This should be for the, like, handle animations. 26:45.270 --> 26:46.110 Could we do that? 26:46.110 --> 26:47.220 What do you think? 26:47.220 --> 26:48.810 Well, let's keep it like that for now. 26:48.810 --> 26:49.320 It's good. 26:49.320 --> 26:50.730 I'll see you in the next video.
