WEBVTT 00:00.000 --> 00:00.510 Hello guys. 00:00.510 --> 00:01.440 Welcome to the video. 00:01.440 --> 00:05.610 In this one I want to show you one of the traps we are going to make. 00:05.610 --> 00:10.020 This is more like a moving trampoline rather than a trap. 00:10.020 --> 00:11.160 But still it is nice. 00:11.160 --> 00:12.510 And I want to show you how to do that. 00:12.510 --> 00:17.520 Okay, so I think I'm going to place this trampoline over here while we're testing it. 00:17.520 --> 00:21.090 So I'm going to just delete this trap from here. 00:21.090 --> 00:22.140 I don't need it. 00:22.260 --> 00:29.010 And I want to take this block over here, select it, and I want to move it to the left just a bit. 00:29.010 --> 00:33.000 So I have sort of a space to jump up okay. 00:33.000 --> 00:36.750 Now let's go to Asset graphic. 00:38.900 --> 00:40.490 We need traps. 00:40.490 --> 00:42.410 And there is this trampoline. 00:42.500 --> 00:45.920 So this has an idol and jump animation. 00:45.920 --> 00:49.490 We're going to select both of them dual pixel per unit 16. 00:49.940 --> 00:52.160 And I'm going to drag one of them here. 00:52.160 --> 00:54.620 Let's change certain layer to. 00:55.300 --> 00:56.740 Uh, trap. 00:57.190 --> 01:00.880 I think we can have all of the components on one game object for this one. 01:00.880 --> 01:04.540 So I'm going to do trap trampoline. 01:04.660 --> 01:05.620 All right. 01:06.100 --> 01:13.090 Now let's go to Assets Animations here I think it's time to create folder for traps. 01:13.770 --> 01:14.700 Sorry. 01:14.700 --> 01:15.540 This should be. 01:16.340 --> 01:17.210 Trumps. 01:17.210 --> 01:19.490 Let me take this. 01:19.490 --> 01:26.960 Put it into a folder and inside I want to make an animator controller for Trump. 01:26.960 --> 01:28.610 Trampoline. 01:28.640 --> 01:31.100 AC animator controller. 01:31.680 --> 01:34.320 Then I drag it on the object. 01:35.440 --> 01:39.280 And also we need a box collider for this one. 01:39.550 --> 01:41.230 But this one going to be a trigger. 01:41.230 --> 01:43.210 Let me focus on a trap. 01:43.450 --> 01:43.960 Yeah. 01:43.960 --> 01:46.690 And uh, we're going to just. 01:47.980 --> 01:53.710 Place it somewhere here and trigger Collider for this one will be somewhere here. 01:53.710 --> 01:55.600 Okay, this is good. 01:56.110 --> 01:59.710 Now let's go and make some animations. 01:59.710 --> 02:00.820 It's over here. 02:00.820 --> 02:01.780 Create. 02:02.140 --> 02:05.890 I'm going to do trampoline idle. 02:07.220 --> 02:08.870 We're going to go to graphics. 02:09.420 --> 02:14.400 Trump's trampoline, could the ideal one then create a new one? 02:15.410 --> 02:16.520 Trumbo. 02:17.120 --> 02:19.700 Lane activated. 02:19.760 --> 02:20.300 Okay. 02:20.300 --> 02:23.090 And for this, we need these sprites over here. 02:23.090 --> 02:24.770 Sample rate going to be. 02:25.720 --> 02:28.540 20 and let me see the animation. 02:30.330 --> 02:31.920 Yeah, this is good, I think. 02:31.950 --> 02:33.660 You okay? 02:33.780 --> 02:36.270 Let's select this animation. 02:37.860 --> 02:38.970 Uh, traps. 02:40.040 --> 02:42.350 Trampoline activated. 02:42.350 --> 02:46.160 And I'm going to uncheck loop time because I need it to be activated only once. 02:46.400 --> 02:47.510 Just to be sure. 02:49.180 --> 02:52.720 Then on the animator, I think we just need a trigger. 02:52.720 --> 02:53.950 Activate. 02:56.310 --> 03:00.030 And we're going to make transition to activate it with a trigger. 03:01.260 --> 03:06.420 Activate has exit time and check transition duration zero, but transition back. 03:06.420 --> 03:10.860 Going to have an exit time of one with the transition duration zero. 03:11.010 --> 03:12.090 Nice. 03:12.120 --> 03:17.850 Now we need a script that will detect player and push it up when we need to. 03:17.880 --> 03:23.610 For that, I'm going to make a new method on the player script because we need to push player from outside 03:23.610 --> 03:29.430 of a script, but functionality can be inside just like a knockback and we are something similar. 03:29.700 --> 03:30.930 Let's go. 03:32.200 --> 03:33.220 Somewhere. 03:33.220 --> 03:35.170 Maybe, I don't know. 03:35.170 --> 03:36.130 Over here. 03:36.790 --> 03:40.000 I'm going to do public void push. 03:40.090 --> 03:44.860 And for the push we're going to need vector two direction. 03:44.860 --> 03:49.990 So this will define the power that will say how much we're going to push the player. 03:51.510 --> 03:57.900 And we're going to need to pass float duration, because I want to take away control from the player 03:57.900 --> 03:59.250 while we're pushing him. 03:59.250 --> 04:01.350 We're not going to use this only for the trampoline. 04:01.350 --> 04:03.210 We're also going to use this for another trap. 04:03.210 --> 04:05.040 So this will be multifunctional. 04:05.040 --> 04:10.830 And if you don't want to have duration, we can simply pass maybe a zero by default. 04:10.830 --> 04:14.070 So if you don't pass any value to this method it will be zero. 04:14.070 --> 04:18.090 Then we need a private eye enumerator. 04:18.090 --> 04:19.500 We need a coroutine. 04:20.160 --> 04:21.810 Push core. 04:22.080 --> 04:23.520 Core. 04:24.560 --> 04:25.310 Teen. 04:25.790 --> 04:27.230 And this. 04:27.850 --> 04:33.010 Will also take two parameters vector two direction and float duration. 04:33.010 --> 04:37.450 And then we're going to do can be controlled equals to false. 04:37.980 --> 04:39.780 Then we're going to push RB. 04:39.780 --> 04:44.670 But before we do that, I want to reset velocity that player had before we pushed him. 04:44.670 --> 04:51.120 So I'm going to do RB velocity equals to vector 2.0 which is zero zero. 04:51.120 --> 04:53.580 So we're going to stop any velocity we had. 04:53.580 --> 04:55.860 And we're going to give it a new velocity. 04:55.860 --> 05:02.520 And this time I want to use RB add force into direction. 05:02.520 --> 05:04.650 And we're going to type force mode. 05:06.170 --> 05:07.010 Impulse. 05:07.190 --> 05:14.960 So impulse force mode will add an instant velocity to the player, and it's going to be a bit more, 05:14.990 --> 05:19.310 I would say natural because force will be applied by physics engine. 05:19.310 --> 05:22.220 So it's going to be like real nicely. 05:22.220 --> 05:25.070 It's going to feel physically correct. 05:25.070 --> 05:25.700 Yeah. 05:25.910 --> 05:31.100 And then we're going to do yield return new wait for a seconds of duration. 05:31.100 --> 05:33.380 And then we're going to do can be controlled. 05:33.380 --> 05:34.130 True. 05:34.400 --> 05:34.940 All right. 05:34.940 --> 05:36.800 So this is a push coroutine. 05:36.890 --> 05:39.380 And we're going to start it over here. 05:39.380 --> 05:42.950 Start coroutine push coroutine. 05:43.070 --> 05:45.800 And we're going to pass direction and duration. 05:46.160 --> 05:46.790 Very well. 05:46.790 --> 05:48.980 Nothing else for now but. 05:50.050 --> 05:50.650 Sorry. 05:50.650 --> 05:53.230 Maybe you need to see this before we do this. 05:53.230 --> 05:55.720 I also want to go to the update. 05:57.680 --> 06:03.890 And here, if we return from a method and player cannot be controlled, we still need to update his 06:03.890 --> 06:04.520 animations. 06:04.520 --> 06:12.050 But I don't want to break execution order over here, so I'll just call this handle animation. 06:14.210 --> 06:16.880 And I will call handle collision. 06:17.700 --> 06:18.300 Just in case. 06:18.300 --> 06:22.020 So maybe if he'll be pushed into the wall, he can just do a wall slide. 06:22.020 --> 06:22.590 Okay. 06:22.860 --> 06:23.670 Very nice. 06:23.670 --> 06:25.530 That's all the code we need here. 06:25.530 --> 06:28.110 Now let's go back to unity. 06:28.110 --> 06:35.070 And in the scripts we want to make C sharp script trap, trampoline. 06:35.070 --> 06:36.150 It's not really a trap. 06:36.150 --> 06:40.680 It doesn't do anything bad, I guess, but let's keep it within one, you know? 06:40.950 --> 06:41.370 Uh. 06:43.930 --> 06:48.310 Spectrum, I don't know, like all together, all of them will be traps. 06:48.310 --> 06:49.090 Yeah. 06:49.090 --> 06:53.800 So on this trap, we need to detect if player entered the trigger. 06:53.800 --> 06:57.430 So on trigger enter 2D, um player. 06:57.430 --> 06:59.620 Player equals to man. 06:59.620 --> 07:01.150 Now I wish I would use just tag. 07:01.150 --> 07:03.340 I think it would be more. 07:03.610 --> 07:05.770 I think it would be faster to type. 07:06.190 --> 07:11.980 Yeah this one then if player not equals to null then player push. 07:12.560 --> 07:15.230 And here we need to pass a bunch of variables. 07:15.770 --> 07:24.980 So one of them will be, uh, serialized field private vector two push direction and serialized field. 07:24.980 --> 07:26.660 Private float. 07:27.080 --> 07:28.610 It's going to be, um. 07:30.920 --> 07:34.610 Duration, and I want to make it 0.5 by default. 07:36.350 --> 07:37.070 Yeah. 07:37.310 --> 07:39.590 Also, I have an idea. 07:39.590 --> 07:46.430 But before I tell you about this idea, let's just try push direction and duration here. 07:46.430 --> 07:50.480 Yeah, let's just save this and let's go back to unity. 07:52.390 --> 07:54.310 Now there is this trampoline. 07:54.520 --> 07:56.770 Oh, something else here I forgot. 07:57.600 --> 08:00.540 Let's go to script. 08:00.540 --> 08:04.530 Make a private animator anim. 08:05.190 --> 08:11.250 And over here I'm going to do anim set trigger. 08:11.830 --> 08:12.730 Activate. 08:13.270 --> 08:15.640 And we need to get component of that activate. 08:15.640 --> 08:17.140 I think we can just do return. 08:17.140 --> 08:17.770 Why not? 08:19.010 --> 08:19.430 Yet to come. 08:19.700 --> 08:20.000 Wait. 08:20.000 --> 08:20.990 This will be. 08:20.990 --> 08:21.230 Yeah. 08:21.230 --> 08:23.630 This can be activated a couple of times, not just once. 08:23.630 --> 08:24.890 So I'll do. 08:26.430 --> 08:27.270 Awake. 08:28.970 --> 08:30.710 And you get component of animator. 08:30.740 --> 08:31.490 Nice. 08:31.490 --> 08:32.780 Now let's save this. 08:32.780 --> 08:34.730 Let's go back to unity. 08:36.650 --> 08:43.520 I'm just going to put the script on the trampoline like so, and push direction will define how far 08:43.520 --> 08:47.210 it is pushed to the left or right on the x. 08:47.210 --> 08:53.780 So this is x velocity and y velocity will define push up I think for this one it's not supposed to be 08:53.780 --> 08:57.260 pushed uh, to the left or right only up. 08:57.260 --> 09:01.730 So I'm going to put maybe 25 on the Y. 09:02.810 --> 09:04.640 Let's go to the game window. 09:07.310 --> 09:08.120 And. 09:10.090 --> 09:10.870 A subway. 09:12.310 --> 09:13.480 Oh is trigger. 09:14.280 --> 09:15.810 Let's do is trigger. 09:16.390 --> 09:21.820 And now I'm supposed to be able to walk into this trampoline and I'm going to be pushed up. 09:22.090 --> 09:23.230 Yay! 09:23.530 --> 09:24.370 Check this out. 09:24.370 --> 09:25.510 Man, this is so fun! 09:27.190 --> 09:27.820 Hahaha! 09:28.210 --> 09:33.460 I love it so much and you still can control the character after the push. 09:34.220 --> 09:34.910 Yeah. 09:36.480 --> 09:37.560 This is so good. 09:37.560 --> 09:38.670 I love it so much. 09:38.670 --> 09:45.810 Now this object, by the look of it, supposed to push the player only into direction. 09:45.810 --> 09:47.760 It is like going up right? 09:47.760 --> 09:51.390 And we can see the animation is going into this direction. 09:51.840 --> 09:58.260 Uh, luckily for us, we can see that up vector of this object is also going up. 09:59.960 --> 10:02.510 That's the transform of it. 10:02.510 --> 10:06.020 And we can see the yellow arrow or green green arrow. 10:06.020 --> 10:06.320 Sorry. 10:06.320 --> 10:07.130 I'm colorblind. 10:07.130 --> 10:09.440 It's difficult for me to define colors. 10:09.440 --> 10:10.400 I think it's green. 10:10.400 --> 10:12.470 So green arrow pointing up. 10:12.650 --> 10:16.100 That is a y of the object. 10:18.500 --> 10:19.010 Yeah. 10:19.010 --> 10:23.030 If we go here and click 2D now, it's going to be 3D. 10:23.030 --> 10:26.420 And we can see that green is responsible for the arrow up. 10:26.420 --> 10:28.910 So we can go to the script. 10:29.270 --> 10:39.410 And instead of using push direction like that we can use vector dot up and we can multiply it by power. 10:39.410 --> 10:41.780 Let's do serialize field private. 10:42.600 --> 10:43.410 Load. 10:44.370 --> 10:45.810 Push power. 10:46.780 --> 10:47.500 Nice. 10:47.500 --> 10:53.020 Now I don't need a push direction because anyway, we're not controlling X over here. 10:53.020 --> 10:54.310 We only controlling y. 10:54.310 --> 10:59.350 So by typing vector two dot up we're going to have zero and one. 10:59.350 --> 11:05.140 And we can just multiply it by push power just like that. 11:05.500 --> 11:07.090 Let me remove this one. 11:08.160 --> 11:11.250 And sorry, this one should be multiplied by push power. 11:11.790 --> 11:14.100 Now I can save this. 11:14.610 --> 11:22.980 And because this arrow is pointing up and we push in player according to the place where arrow is pointing, 11:22.980 --> 11:24.360 let me do 25. 11:24.360 --> 11:26.100 Push power over here. 11:26.280 --> 11:26.790 Yeah. 11:26.790 --> 11:27.690 We can. 11:27.690 --> 11:28.500 Sorry. 11:29.620 --> 11:34.240 We can take this trampoline and we can rotate it, maybe like that. 11:34.810 --> 11:42.790 And now when we rotate in the object, and now once object is rotated just a bit, his up vector goes 11:42.790 --> 11:43.600 to the left. 11:43.600 --> 11:49.180 If yours looks different, you need to go here and change from global to local. 11:49.180 --> 11:53.350 Okay, so we can rotate object let's say by 90 degree. 11:53.350 --> 11:56.800 And now the up arrow goes here. 11:56.800 --> 12:04.360 And because we push in player with the vector dot up multiplied by push power play are going to be pushed 12:04.360 --> 12:05.170 to the left. 12:05.170 --> 12:07.600 And we do need to adjust vector over here. 12:07.600 --> 12:09.130 We can just rotate the drop. 12:09.130 --> 12:11.260 And that will do everything for us. 12:11.260 --> 12:13.840 Now let's go ahead and try this. 12:14.990 --> 12:15.680 Oh, no. 12:16.940 --> 12:18.560 Didn't work for some reason. 12:18.590 --> 12:20.300 Wait, let me check that. 12:23.460 --> 12:24.390 Supposed to work. 12:24.390 --> 12:25.890 I just tested this. 12:25.890 --> 12:27.570 I'm doing something wrong. 12:29.710 --> 12:31.420 Vector two dot app. 12:32.710 --> 12:33.550 Oh, sorry. 12:33.550 --> 12:34.120 Not vector. 12:34.120 --> 12:35.110 I am so sorry. 12:35.140 --> 12:36.760 Transform app. 12:36.760 --> 12:41.710 We need to use transform app because we want to have up direction of this object. 12:41.710 --> 12:42.220 Yeah. 12:42.580 --> 12:43.420 My bad. 12:43.420 --> 12:45.430 So now this is how it's going to be. 12:46.170 --> 12:50.910 And because this is transform up for this object, this is going to be multiplied with a push power. 12:50.910 --> 12:54.900 And now we go here and queue. 12:55.410 --> 12:58.830 And very cool I love it so much. 12:58.830 --> 13:01.530 So this is it for the trampoline. 13:01.770 --> 13:04.710 Let me make it as a prefab and let me try something. 13:04.710 --> 13:11.790 I'm going to make it as a prefab and let's say this one will be zero over here I'm going to apply. 13:11.790 --> 13:13.470 Oh it's not needed okay. 13:13.560 --> 13:18.360 And another trap I want to place over here. 13:22.570 --> 13:28.060 This is this feels, um, wrong because we don't have any platform here. 13:29.080 --> 13:30.760 Well, let's say we have a platform there. 13:30.760 --> 13:32.200 Why not just quickly? 13:34.790 --> 13:35.600 Just like that. 13:36.260 --> 13:39.740 And now we can make some sort of chain of movement. 13:41.160 --> 13:41.850 You. 13:43.290 --> 13:45.480 And this is so fun, I love it. 13:50.210 --> 13:50.780 Yeah. 13:50.780 --> 13:51.230 Cool. 13:51.230 --> 13:51.710 Right? 13:51.710 --> 13:55.910 And if you want to increase the push power, you can just change the variable over here. 13:55.940 --> 14:00.230 Now I'm going to remove this I'm just going to place this somewhere. 14:01.300 --> 14:03.250 Like at someplace interesting. 14:05.230 --> 14:06.460 Maybe just here. 14:07.550 --> 14:08.330 Why not? 14:09.440 --> 14:09.620 Yeah. 14:09.620 --> 14:10.490 Let it be there. 14:10.520 --> 14:16.520 Now I'm going to, uh, save the project, and we're going to go to the next video.
