WEBVTT 00:00.000 --> 00:00.420 Hello guys. 00:00.420 --> 00:01.410 Welcome to the video. 00:01.410 --> 00:04.500 In this one we're going to make a falling platform. 00:04.500 --> 00:06.330 The script is very easy to do. 00:06.330 --> 00:11.400 And this is basically a practice of all what we did before like sort of a combination of it. 00:11.400 --> 00:16.080 I will explain as much as I can when we doing some new things, but things that we did before, I'm 00:16.080 --> 00:17.100 not going to explain much. 00:17.100 --> 00:17.760 All right. 00:18.210 --> 00:20.250 So let's make the falling platform. 00:20.250 --> 00:21.720 It's going to fly in the air. 00:21.720 --> 00:24.510 Then when a player steps on the platform, it's going to fall. 00:24.510 --> 00:26.790 And that's basically all the functionality. 00:27.060 --> 00:28.530 First we need to make GameObject. 00:28.530 --> 00:29.400 So let's do it. 00:29.400 --> 00:31.110 Graphic traps. 00:31.980 --> 00:37.140 Uh following platform, select them both and set pixel per unit to 16. 00:37.530 --> 00:44.280 Then let's take one of the sprites, drag them into the scene, make certain layer uh, trap. 00:45.570 --> 00:54.990 We also need a rigid body on this one rigid body 2D and let's name it as trap Olin platform. 00:54.990 --> 00:57.540 And let me quickly say, why do we need a rigid body. 00:57.540 --> 00:59.670 So we're going to set it to kinematic. 00:59.670 --> 01:02.790 And it's not going to be affected by physics or anything like that. 01:02.790 --> 01:05.520 And it's going to stand over there for example. 01:05.520 --> 01:05.940 Right. 01:05.940 --> 01:11.010 But when we want it to fall, we're going to switch body type from kinematic to dynamic, and it's going 01:11.010 --> 01:11.760 to fall like that. 01:11.760 --> 01:15.210 So that's the only reason we need a rigid body on this platform. 01:15.210 --> 01:20.670 Let's change collision detection to continuous and interpolate interpolate. 01:20.970 --> 01:21.960 Nice. 01:21.960 --> 01:26.880 Now we also need a box collider so we can stand on the platform just like that. 01:26.880 --> 01:29.130 And we need to set layer to ground. 01:29.580 --> 01:31.050 There are other things we need to do. 01:31.050 --> 01:38.430 But first let's set up animations and we're going to go to asset animations traps controllers make a 01:38.430 --> 01:39.180 new one. 01:40.710 --> 01:43.380 Trampoline platform. 01:44.370 --> 01:46.470 Let's put it on the platform. 01:46.470 --> 01:47.760 Yeah, we have animator. 01:47.760 --> 01:48.210 Nice. 01:48.210 --> 01:49.350 Now we need animations. 01:49.350 --> 01:53.490 Let's create and inotropes trap. 01:53.610 --> 01:55.620 All in platform. 01:55.890 --> 01:56.880 Uh, active. 01:58.840 --> 02:01.630 Can I go to graphics traps following platform? 02:01.630 --> 02:03.820 Take these sprites on. 02:03.820 --> 02:04.990 Put them here. 02:04.990 --> 02:06.940 Sample array 20. 02:06.940 --> 02:08.620 Then we need new clip. 02:08.800 --> 02:13.300 And I'm just here I'm just going to select this one and change active to. 02:14.700 --> 02:16.500 Of save it. 02:16.500 --> 02:20.010 Take the off sprite, put it here on the animator. 02:20.010 --> 02:22.050 We're going to select active by default. 02:22.050 --> 02:25.290 And then we're going to transfer to platform off with a trigger. 02:25.960 --> 02:27.130 Deactivate. 02:27.160 --> 02:28.900 Deactivate. 02:31.250 --> 02:33.380 Trigger has exit time and check. 02:34.010 --> 02:35.750 Transition duration zero. 02:35.780 --> 02:36.920 Very nice. 02:36.920 --> 02:38.750 And that's all for the setup. 02:38.780 --> 02:40.280 Now we need a script for this. 02:40.310 --> 02:47.390 I'm going to go to scripts make a new C sharp script trap fallen platform. 02:47.720 --> 02:52.940 The functionality is somewhat similar to the trap soul because we have a movement on this platform, 02:52.940 --> 02:58.070 but I don't see really a reason to make entire inheritance just for one method. 02:58.070 --> 03:02.030 So I think we're just going to write everything from scratch, uh, how it's going to work. 03:02.030 --> 03:06.800 If we just go to play mode right now, it's going to spin the propeller over there, but it doesn't 03:06.800 --> 03:07.910 look like it's flying. 03:07.910 --> 03:09.500 It's standing there flat. 03:09.500 --> 03:15.590 So what I want to do here is to save position above the platform and below the platform. 03:15.590 --> 03:21.380 And this will be the travel distance for the platform and platform going to move between these two positions 03:21.380 --> 03:22.100 real fast. 03:22.100 --> 03:23.870 And it's going to look like it's flying. 03:24.110 --> 03:29.990 So first let's go ahead and save the position just so you understand how it's going to work I'm going 03:29.990 --> 03:34.370 to make public vector three uh waypoints and then we're going to hide it. 03:34.370 --> 03:37.250 But first I want you to see how it's working altogether. 03:37.250 --> 03:39.140 Let's just make it as array. 03:40.170 --> 03:45.120 And let's make serialize field private float travel distance. 03:45.120 --> 03:49.680 And we need serialize field private float, maybe speed just like that. 03:49.680 --> 03:52.770 And I'm going to make it equals to point 75 F by default. 03:52.770 --> 03:55.050 Because it's going to be really small value there. 03:55.200 --> 03:56.370 Now. 03:57.110 --> 03:58.940 In the start over here. 03:58.940 --> 04:00.350 I'm going to do this. 04:00.500 --> 04:02.240 Actually, let's make a method real quick. 04:02.240 --> 04:04.340 Setup way. 04:05.230 --> 04:05.890 Points. 04:05.890 --> 04:06.370 Sorry. 04:06.370 --> 04:07.750 It should be a void over here. 04:07.780 --> 04:08.290 Void? 04:08.290 --> 04:08.680 Yeah. 04:08.680 --> 04:10.600 So how do we set up waypoints? 04:10.600 --> 04:18.010 We're going to have, uh, waypoint array with the length of two because we only need two waypoints 04:18.010 --> 04:18.700 up and down. 04:18.700 --> 04:19.330 Right. 04:19.510 --> 04:22.450 And then I'm going to take waypoint equals to zero. 04:22.450 --> 04:25.570 And I'm going to set it equals to transform position. 04:26.730 --> 04:28.950 Plus the offset for the Y. 04:28.980 --> 04:31.560 So actually first let's decide on the offset. 04:31.560 --> 04:32.820 And this is how it's going to be. 04:32.820 --> 04:39.360 Plot y offset is equals to travel distance divided by two y like that. 04:39.360 --> 04:43.470 Well let's say travel distance of the platform is one. 04:43.470 --> 04:46.500 We want to move it up and down. 04:46.500 --> 04:49.620 But when platform starts it is starting over here. 04:49.620 --> 04:56.880 And if we want to get travel distance of one we just need waypoint on minus five and waypoint on the 04:56.880 --> 04:57.210 five. 04:57.210 --> 05:02.970 Basically we just uh, take the travel distance and divide it by half and then set in one position half 05:02.970 --> 05:04.500 below and half above. 05:04.800 --> 05:05.880 This is how it is. 05:06.030 --> 05:12.390 So waypoint zero is equals to transform.position plus new Vector3 zero y offset zero. 05:12.390 --> 05:13.650 And then. 05:14.340 --> 05:19.740 Second waypoint, with the index one going to use minus y offset. 05:20.130 --> 05:21.060 Very nice. 05:21.060 --> 05:25.470 Let's go ahead to start method and call setup waypoints. 05:25.470 --> 05:28.080 And I just want to show you how it's going to work. 05:28.080 --> 05:30.120 We're going to go back to unity. 05:34.600 --> 05:35.200 Over here. 05:35.200 --> 05:37.870 I want to set the position of the platform to zero. 05:38.440 --> 05:39.520 Just for example. 05:39.520 --> 05:40.510 So it is here. 05:40.510 --> 05:42.850 It has y zero and travel distance. 05:42.850 --> 05:44.440 Let it be one. 05:44.770 --> 05:46.060 Let's go to play mode. 05:47.610 --> 05:51.570 And over here we can see that x position is the same as before. 05:51.570 --> 05:55.080 But y position has zero five and -0 five. 05:55.080 --> 06:01.170 So now when we ask this platform to move to one of the waypoints, it's going to move to minus five. 06:01.910 --> 06:07.010 Then to five minus five, five, minus five five and it's going to look like it's flying. 06:07.010 --> 06:09.230 Basically this is what we need to do. 06:09.260 --> 06:12.170 So now we know how the waypoints are working. 06:12.170 --> 06:13.220 How do we set up them. 06:13.220 --> 06:17.660 I'm going to make it private and I'm going to make update. 06:18.260 --> 06:22.730 And below the update I need method private void handle movement. 06:22.730 --> 06:23.750 Let it be like that. 06:23.750 --> 06:27.650 So here we're going to do Transform.position equals to vector two. 06:27.680 --> 06:34.460 Move towards from Transform.position to a waypoint with a fly speed. 06:34.460 --> 06:36.140 Sorry, we need an index. 06:36.140 --> 06:37.190 I forgot the index. 06:37.190 --> 06:43.880 So let's do private int we point index okay. 06:43.880 --> 06:44.720 Very nice. 06:44.720 --> 06:47.600 So over here we're going to use waypoint index. 06:47.600 --> 06:52.430 And speed will be just speed multiplied by time dot delta time. 06:52.430 --> 06:53.300 Nice. 06:53.300 --> 06:56.330 Now we're going to check if we are close enough to the waypoint. 06:56.330 --> 06:57.770 If uh vector2. 06:57.770 --> 07:05.600 The distance from transform.position to a waypoint index less than 0.1 F, then we are close enough. 07:05.690 --> 07:08.660 We can take waypoint index and do plus plus. 07:08.660 --> 07:16.580 And if waypoint index is bigger or equals to waypoint length, then waypoint index equals to zero is 07:16.580 --> 07:17.960 going to handle movement. 07:18.470 --> 07:21.380 I'm going to call this method in the update handle movement. 07:21.710 --> 07:28.220 And just in case we need to switch it off at some point I'm going to make a boolean over here. 07:28.220 --> 07:30.140 Private bool can move. 07:30.140 --> 07:30.890 Uh yeah. 07:30.890 --> 07:33.950 Let's make it public for now so we can see it later on. 07:33.950 --> 07:34.970 I'm going to hide it. 07:37.410 --> 07:43.050 And over here, if can move equals to false, then return. 07:43.290 --> 07:47.220 Let's save this and let's go see how does it work right now. 07:48.390 --> 07:53.070 So I'm going to set travel distance really low like 0.6 maybe. 07:53.070 --> 07:55.050 And I'm going to set Canmove true. 07:55.050 --> 07:58.380 And we're going to see platform in the action. 07:59.300 --> 08:01.850 And now it's looking nice and like, you know. 08:02.700 --> 08:08.370 Low t reading like how it works if you set lower travel distance to something like 0.4. 08:08.400 --> 08:09.600 Going to be even better. 08:12.270 --> 08:13.050 Yeah. 08:13.080 --> 08:18.630 Now the goal is to land on the platform and detect that we landed on the platform. 08:18.630 --> 08:19.320 Right. 08:20.210 --> 08:24.440 Uh, I'm going to place platform over here and player over here. 08:24.950 --> 08:28.520 So how are we going to detect that player touched the platform? 08:28.520 --> 08:29.750 There are many ways to do that. 08:29.750 --> 08:33.080 And one of them would be to use Trigger Collider. 08:34.640 --> 08:40.190 I think I didn't show you this before, but you can actually add two colliders to the game object and 08:40.190 --> 08:46.010 set one of them as is trigger, and this collider will trigger a method on trigger enter. 08:46.010 --> 08:48.230 We just need to focus on the platform. 08:49.720 --> 08:51.550 Click Edit Collider. 08:52.990 --> 08:56.800 And we need to squeeze it from the sides and from the below. 08:58.000 --> 09:03.790 So this trigger cannot be reached from the sides or from below, because there is a common collider 09:03.790 --> 09:05.530 that will block the movement. 09:05.530 --> 09:09.250 But from the above, it's supposed to be, you know, available. 09:09.250 --> 09:12.490 So over here I'm going to just slightly increase it. 09:12.490 --> 09:17.890 And if you're not sure which collider you are changing, you can see values over here in the collider. 09:17.890 --> 09:22.570 And by dragging them I can see that I'm changing values of the Trigger Collider. 09:22.570 --> 09:23.230 Okay. 09:23.590 --> 09:31.240 So now this collider cannot be entered from the sides or from the below, but it's supposed to be available 09:31.240 --> 09:33.040 from the above of the platform. 09:33.040 --> 09:36.040 So we're going to take the collider and just slightly increase it. 09:36.040 --> 09:39.100 Like so really like just by a bit. 09:39.100 --> 09:44.080 If you're not sure which collider you are changing, you take a look at the variables over here and 09:44.080 --> 09:46.540 if they are changing means you're changing the trigger. 09:47.330 --> 09:48.560 You can see that right? 09:48.590 --> 09:49.100 Okay. 09:49.100 --> 09:51.530 So I'm going to make it somewhat like this. 09:51.530 --> 09:54.410 And let's move this collider over here. 09:54.710 --> 09:57.050 Now we can snap them like so. 09:57.140 --> 09:59.150 And I just want to make sure it is working. 09:59.150 --> 10:01.610 So I'm going to go ahead make on trigger. 10:01.610 --> 10:04.220 Enter on trigger enter to D. 10:05.630 --> 10:07.850 Sheila, I know it's going to work, but I want to. 10:07.880 --> 10:09.170 I want you to see it. 10:09.170 --> 10:09.560 Let's do. 10:09.560 --> 10:10.400 Player. 10:11.120 --> 10:14.360 Player equals to collision GameObject Getcomponent. 10:14.390 --> 10:15.140 Our player. 10:17.040 --> 10:20.700 And if player not equals to null, then debug log. 10:21.240 --> 10:23.490 Platform should fall. 10:23.970 --> 10:24.750 Okay. 10:24.750 --> 10:26.220 Gonna save it. 10:26.670 --> 10:27.600 Go back. 10:29.580 --> 10:31.470 And let me jump on the platform. 10:36.220 --> 10:36.610 Boom. 10:37.650 --> 10:38.970 Platform should fall. 10:39.270 --> 10:40.440 Very nice. 10:40.440 --> 10:43.710 So how do we achieve the falling of the platform? 10:44.220 --> 10:46.230 I think it should fall with a delay. 10:46.260 --> 10:47.580 Not immediately. 10:47.580 --> 10:49.980 And for that we could use a coroutine. 10:49.980 --> 10:53.280 Or we could use, um, invoke. 10:53.310 --> 10:56.190 I never showed you what is invoke, but it also can be used. 10:56.190 --> 10:57.750 So I think it's the time. 10:57.750 --> 11:01.920 Let's go ahead and quickly make a header platform. 11:01.920 --> 11:04.110 All details something like that. 11:04.110 --> 11:07.020 And over here we need serialize field, private float. 11:07.230 --> 11:09.270 Uh whole delay. 11:09.270 --> 11:11.640 I'm going to make it 0.5 by default. 11:11.640 --> 11:12.510 Nice. 11:12.510 --> 11:15.300 Now we're going to make a method. 11:16.320 --> 11:20.010 Private void drop off platform. 11:21.270 --> 11:25.590 Oh let's use switch off platform better. 11:25.830 --> 11:30.090 And in the switch off platform we're going to switch body type of the rigid body. 11:30.090 --> 11:32.280 And also going to increase gravity scale. 11:32.280 --> 11:38.040 So it falls faster I guess and animation should be triggered I guess for that we need a bunch of components. 11:38.130 --> 11:40.890 So let's go ahead and get components over here. 11:42.000 --> 11:49.140 Private Animator, anim Revit Rigidbody, 2d, ARB and we need colliders on the object so we can switch 11:49.140 --> 11:49.740 them off. 11:49.740 --> 11:53.190 And player would not be able to stand on the platform anymore. 11:53.190 --> 11:59.340 So I'm going to do Private Box Collider 2D, but I'm going to make it as array because we have two colliders 11:59.340 --> 12:03.300 and I'm going to just call it colliders then in the wake. 12:04.780 --> 12:10.150 We're going to do anim Getcomponent of animator Richard by the getcomponent of rigidbody. 12:10.150 --> 12:16.420 And for colliders we're going to do equals to getcomponent with the plural over here. 12:16.450 --> 12:16.810 All right. 12:16.810 --> 12:19.870 With the letter S get components of box Collider. 12:20.600 --> 12:24.290 So they all will be in the variables saved. 12:24.290 --> 12:26.000 Now we can go back to the. 12:26.510 --> 12:28.370 Switch off platform over here. 12:28.370 --> 12:33.020 We're going to do anim set trigger off deactivate. 12:33.020 --> 12:36.980 Then RB is kinematic equals to false. 12:36.980 --> 12:44.420 Also I want to set gravity scale to something like 3.5 and RB drag equals 2.5. 12:44.420 --> 12:45.710 This will add a bit of. 12:45.710 --> 12:48.830 The resistance of the air will make it more natural. 12:48.830 --> 12:52.700 And also we want to take let's do for each loop. 12:52.700 --> 12:56.930 And here we're going to use Box Collider as a variable box collider 2D. 12:56.930 --> 13:03.110 So for each box Collider Collider in colliders that we collected before. 13:04.350 --> 13:09.060 We're going to do collider enable enabled equals to false. 13:09.060 --> 13:10.980 So this will switch off the collider. 13:11.010 --> 13:12.030 Very nice. 13:12.030 --> 13:15.030 Now as I said before we should call this method with a delay. 13:15.060 --> 13:16.350 This is how you call method. 13:16.350 --> 13:18.930 With a delay you can type invoke. 13:19.660 --> 13:25.240 Then in a quotation marks, you need to type the name of a method like this switch of platform. 13:25.240 --> 13:31.570 And then after a comma, you give it time as a delay and we have something drop delay. 13:32.280 --> 13:33.090 What's the variable? 13:33.090 --> 13:33.990 Full delay. 13:34.020 --> 13:38.280 Okay, uh, before we go and test this, I want to say something here. 13:38.280 --> 13:41.820 It is not very good practice to type methods in quotation marks. 13:41.820 --> 13:43.710 And this is what I learned with experience. 13:43.710 --> 13:46.110 Because you can make a mistake over here. 13:46.110 --> 13:47.040 It will not work. 13:47.040 --> 13:50.820 Also, you may change methods name later on and it will not change it over here. 13:50.820 --> 13:53.370 So it's really difficult to keep track of this. 13:53.370 --> 13:59.070 So instead we can type name of parenthesis switch off platform. 13:59.460 --> 14:00.450 I'm gonna work as well. 14:00.450 --> 14:03.810 But now if you change method it's going to change it here as well. 14:04.290 --> 14:09.120 Okay let's save this and let's go and see how platform is falling. 14:15.900 --> 14:17.550 So it is flying over there. 14:17.550 --> 14:18.930 I'm going to jump on the platform. 14:18.930 --> 14:19.560 Boom! 14:20.010 --> 14:21.060 And it falls. 14:22.030 --> 14:23.320 Not that bad. 14:23.320 --> 14:25.180 Yeah, I like it. 14:25.570 --> 14:27.250 Was sort of jittering, I think. 14:27.250 --> 14:30.520 So I just need to see it once again because felt glitchy. 14:31.840 --> 14:33.580 I'm going to just take the platform. 14:39.360 --> 14:42.240 Also, you'll see that all of the platforms are flying together. 14:42.240 --> 14:44.820 Now we're going to fix it with a randomizer. 14:44.820 --> 14:46.200 But first let's see it. 14:49.710 --> 14:51.660 Oh, you see how it's struggling to fall. 14:51.660 --> 14:53.910 And I know why it's struggling to fall. 14:53.940 --> 14:56.010 Because it's affected by gravity. 14:56.010 --> 15:01.050 But also it is trying to move with a this handle movement. 15:01.770 --> 15:07.650 So we need to go to the switch off platform and make and move equals to false. 15:08.130 --> 15:08.610 Yeah. 15:09.830 --> 15:11.630 Uh, let's go ahead. 15:11.780 --> 15:12.980 Double check this. 15:20.340 --> 15:21.030 Yeah. 15:21.800 --> 15:23.840 Better, I like it. 15:26.120 --> 15:29.450 Now there are a couple of things I want to do to improve this mechanic. 15:29.450 --> 15:31.550 One of them is to. 15:32.180 --> 15:35.870 Make some sort of impact when you touching the platform. 15:35.870 --> 15:39.440 And second one is to add difference for the movement. 15:39.440 --> 15:44.990 So different platforms flies with a different, you know, cycle because as of now they all fly in synchronically 15:44.990 --> 15:46.190 and I don't like it. 15:47.170 --> 15:48.820 And let's go back to the script. 15:48.820 --> 15:53.230 So regarding the delay for different platforms we're going to go ahead. 15:54.450 --> 15:57.720 And, uh, make a method private void. 15:58.530 --> 16:01.050 Activate platform. 16:01.820 --> 16:03.800 In which we're going to give it a delay. 16:03.800 --> 16:05.390 So let's do float. 16:05.390 --> 16:10.910 Random delay equals to random range. 16:12.890 --> 16:18.710 Range from zero to let's say 0.6 F, so it's about half of the second. 16:18.710 --> 16:22.940 And it can be widely between 0 and 0.5 F actually 0.59 F. 16:22.970 --> 16:23.450 Yeah. 16:23.450 --> 16:26.120 And that will give it different movement for each platform. 16:26.120 --> 16:28.520 And then over here I'm going to do oh wait a second. 16:28.520 --> 16:29.810 This should not be here. 16:29.810 --> 16:31.940 This should be here in the start. 16:32.950 --> 16:33.700 Yeah. 16:33.850 --> 16:35.470 And this one will just do. 16:36.530 --> 16:39.350 And move equals to true just like that. 16:39.350 --> 16:40.880 And we're going to invoke. 16:42.240 --> 16:46.530 Name of activate platform with a random delay. 16:46.560 --> 16:47.100 Yeah. 16:47.100 --> 16:51.330 Also, I have a trick how to make it all cleaner, but I'm going to show it to you later on. 16:51.480 --> 16:55.590 Uh, now we need to make the impact when you touch the platform. 16:57.300 --> 17:02.070 Let's make a variable sterilized field private float impact speed. 17:02.070 --> 17:05.250 I'm going to make it equals to three by default because I know it's going to work. 17:05.250 --> 17:09.720 And also we need serialize field private float impact duration. 17:09.720 --> 17:12.240 And also I know 0.15 is a good value. 17:12.240 --> 17:15.810 So this is how fast the platform will move when you touch it. 17:15.810 --> 17:19.110 And this for how long platform will move when you touch it. 17:19.110 --> 17:23.340 And we also need a timer private float impact timer. 17:23.340 --> 17:24.900 Now this is how it's going to work. 17:24.900 --> 17:27.180 We're going to decrease timer all the time. 17:27.180 --> 17:31.680 And then when we set value to a positive value then we're going to be decreased from a positive value 17:31.680 --> 17:32.520 to negative. 17:32.520 --> 17:35.910 And a while value is positive we're going to move the platform. 17:36.850 --> 17:38.710 Let's go and make a method. 17:40.990 --> 17:42.100 Somewhere here. 17:42.550 --> 17:47.860 Private void handle impact in which we're going to do this. 17:47.860 --> 17:53.500 If impact timer is less than zero, then return. 17:53.920 --> 17:55.210 Also, we're going to do. 17:55.210 --> 17:57.220 Actually, let me just show you how it's going to work. 17:57.220 --> 18:00.460 I'm going to do impact timer minus equals time dot delta time. 18:00.460 --> 18:05.170 Since delta time is sort of a time in seconds, we're going to decrease this timer all the time while 18:05.170 --> 18:06.190 it is bigger than zero. 18:06.190 --> 18:08.470 If it's less than zero it's not going to work. 18:08.680 --> 18:10.180 I'm going to do debug log. 18:12.250 --> 18:13.420 Move platform. 18:16.070 --> 18:19.610 Now let me make this value public so I can show you how it's going to work. 18:21.870 --> 18:23.640 Let's go to unity. 18:29.470 --> 18:31.450 We can see we have impact timer. 18:31.450 --> 18:34.720 And if I set it to a positive value like three. 18:36.530 --> 18:36.740 Huh? 18:37.040 --> 18:39.350 Oh, I forgot to call method in the update. 18:39.350 --> 18:40.220 I'm so sorry. 18:41.520 --> 18:42.090 Did I not? 18:42.090 --> 18:43.620 Yeah I did not okay. 18:43.650 --> 18:44.610 Update. 18:45.060 --> 18:46.980 Handle impact okay. 18:52.870 --> 18:59.020 So I have a bug timer and if I set it, let's say to three you're going to see how it's decreasing itself. 18:59.580 --> 19:04.530 And we can just move platform down while the timer decreasing itself. 19:05.270 --> 19:11.660 And if we set it to 0.1 while this is happening, we're going to move the platform or another value. 19:11.660 --> 19:15.110 Basically, while value is positive, we're moving the platform down. 19:15.560 --> 19:17.210 So we're going to go over here. 19:17.840 --> 19:25.190 And do transform position equals to vector to move towards from, transform position to and we just 19:25.190 --> 19:29.810 need a position below the platform like current position minus ten on the Y. 19:29.840 --> 19:30.530 Something like that. 19:30.530 --> 19:38.630 So I'm going to do to uh transform position plus vector three dot down multiply it by some number like 19:38.630 --> 19:39.170 ten. 19:39.170 --> 19:42.710 You just need a vector three below the current one we have. 19:42.710 --> 19:48.650 And it's going to have speed that we use to do impact is impact speed. 19:49.490 --> 19:50.150 Impact. 19:50.150 --> 19:52.160 Speed multiplied by time. 19:52.310 --> 19:53.180 Delta time. 19:53.630 --> 19:56.150 I'm going to press enter over here so you can see it. 19:56.150 --> 19:59.300 And that's all what we need to do for the impact actually. 19:59.880 --> 20:01.440 Nice nice, nice nice. 20:01.440 --> 20:05.790 Now we only want to start the timer every time we enter in the trigger. 20:05.790 --> 20:07.170 So I'm going to do this. 20:07.890 --> 20:11.790 Impact timer equals to impact duration. 20:11.790 --> 20:17.160 And also we want to trigger this only once because if we do not switch off possibility of triggering 20:17.160 --> 20:20.760 the impact then you will just push platform down all the time. 20:21.060 --> 20:22.560 So let's go. 20:24.320 --> 20:25.670 Make this private. 20:26.570 --> 20:27.620 Here I'm going to do space. 20:27.620 --> 20:31.070 So it's different and let's do privatebool. 20:32.580 --> 20:35.010 Impact, uh, happened? 20:35.010 --> 20:36.600 Maybe impact happened. 20:36.600 --> 20:37.320 Okay. 20:37.470 --> 20:38.430 Impact happened. 20:39.070 --> 20:41.020 So it's going to be false by default. 20:41.350 --> 20:42.280 But then. 20:43.450 --> 20:44.320 Over here. 20:44.320 --> 20:52.030 Actually, maybe over here, if impact happened, then return cannot be impacted anymore. 20:52.570 --> 20:56.440 And on the enter we're going to do impact happened equals to true. 20:56.440 --> 20:58.630 So we can trigger it only once. 20:58.630 --> 20:59.890 Let's save this. 20:59.890 --> 21:02.080 Let's go back to unity. 21:04.570 --> 21:07.030 I'm going to duplicate the platform. 21:07.330 --> 21:08.920 Hey, duplicate. 21:08.920 --> 21:09.640 Yeah. 21:10.090 --> 21:13.540 And let's maybe place a couple of more here. 21:17.050 --> 21:18.550 So we have platforms. 21:18.760 --> 21:21.880 They line weight, they line together. 21:21.880 --> 21:22.270 Why? 21:22.270 --> 21:24.010 Why they are flying together. 21:25.620 --> 21:27.090 Want them to fly differently. 21:27.090 --> 21:28.200 Let me double check. 21:29.690 --> 21:33.320 Now, because this can move is set to true by default. 21:33.320 --> 21:36.050 Let's select the platforms and make them false. 21:40.360 --> 21:40.840 Yeah. 21:40.840 --> 21:42.460 Now they're flying differently. 21:42.790 --> 21:44.110 I'm going to jump on the platform. 21:44.110 --> 21:45.940 There is impact and it's falling. 21:46.300 --> 21:47.620 Very pretty impact. 21:47.620 --> 21:48.700 I really like it. 21:49.490 --> 21:51.080 Feels natural. 21:51.170 --> 21:51.530 Boom! 21:51.830 --> 21:52.820 And it's falling. 21:56.990 --> 21:57.620 Yay! 21:57.650 --> 21:59.840 So fallen platform is finished. 22:00.410 --> 22:02.690 Took a bit of time, but I hope you like it. 22:02.690 --> 22:03.470 How it works. 22:03.470 --> 22:04.430 I'm going to switch. 22:04.430 --> 22:07.730 I mean, delete this and let's go. 22:07.730 --> 22:08.690 Here. 22:08.690 --> 22:09.350 Hide. 22:09.350 --> 22:10.580 This can move. 22:10.580 --> 22:11.210 Boolean. 22:13.080 --> 22:13.470 Private. 22:13.470 --> 22:15.720 Also, let's make sure it is false by default. 22:16.860 --> 22:17.940 And then. 22:19.010 --> 22:21.830 Oh, I promise to you how to clean this up. 22:21.830 --> 22:28.070 So actually, you can turn a start method into a coroutine and unity will start method anyway. 22:28.070 --> 22:32.210 So if it's a coroutine, coroutine of the start method will be started as well. 22:32.210 --> 22:34.640 So we can do I enumerator over here. 22:34.640 --> 22:37.520 Then we can do calculation of delay. 22:37.520 --> 22:40.970 Then we can do yield return new waitforseconds of random delay. 22:40.970 --> 22:43.550 And then we can make can move equals to true. 22:44.000 --> 22:47.540 I don't know if it's a good idea, but there is a possibility to do that. 22:47.540 --> 22:50.360 And I wanted you to know about this one okay. 22:50.360 --> 22:51.500 Let's save this. 22:51.500 --> 22:55.100 Let's go ahead and make prefab out of the fallen platform. 22:57.390 --> 23:03.150 If you want to recreate the platform after the fallen, you can do it the same way as we did with the 23:03.150 --> 23:03.690 arrow. 23:03.720 --> 23:08.190 You already know how to do that, so I'm just going to make it as a prefab. 23:09.770 --> 23:11.000 Gonna test it once again. 23:11.000 --> 23:13.610 And I'm going to say thank you for paying attention. 23:13.610 --> 23:15.410 Let's go to the next video.
