WEBVTT 00:00.000 --> 00:00.450 Hello guys. 00:00.450 --> 00:01.440 Welcome to the video. 00:01.440 --> 00:04.260 So in this one I want to make respond for the player. 00:04.260 --> 00:08.550 So when he dies he can get on the starting position or something like that. 00:08.550 --> 00:13.260 There are a couple of things we need to do to make it work, but they all are very simple. 00:13.260 --> 00:13.920 Okay. 00:16.070 --> 00:20.480 First, let's make a respawn point so we can use it. 00:20.510 --> 00:22.220 I'm going to go to graphics. 00:22.520 --> 00:27.260 Uh items checkpoints start over here. 00:27.260 --> 00:29.930 We need to be sure they have pixel per unit 16. 00:29.930 --> 00:32.240 So let's, uh, select them. 00:32.920 --> 00:35.740 And make sure you have pixel per unit 16 over here. 00:35.770 --> 00:38.710 Now let's take sprite of the idle one. 00:38.710 --> 00:39.820 Just like that. 00:44.970 --> 00:50.100 I think we can take it and choose layers layer for this one. 00:50.950 --> 00:51.250 Now. 00:51.250 --> 00:51.490 Wait. 00:51.490 --> 00:56.530 Maybe it should be like, maybe enemy should pass by this one and we should see the enemies. 00:56.620 --> 01:00.070 So I think let's put it on the ground. 01:01.770 --> 01:02.340 Let's do it. 01:02.340 --> 01:04.260 Order in layer one. 01:04.950 --> 01:05.760 Okay. 01:06.170 --> 01:06.890 Yeah. 01:07.780 --> 01:08.920 Or is it item. 01:08.920 --> 01:09.370 Yeah. 01:09.370 --> 01:12.520 It's an I think it's an item. 01:13.360 --> 01:13.780 Okay. 01:13.780 --> 01:14.950 Let's keep it as an item. 01:14.950 --> 01:18.520 And then once we have enemies we're going to see what is better working for this one. 01:18.760 --> 01:23.230 And just to be sure it is behind other fruits, I'm going to do minus one here. 01:23.230 --> 01:23.890 Okay. 01:23.890 --> 01:29.800 So now we have a starting point that is on the layer of items I mean certain layer. 01:29.800 --> 01:35.320 And now we need to rename this to something like Start Point. 01:35.320 --> 01:37.810 This is the place where we're going to start the game. 01:39.760 --> 01:43.690 And for this one, we don't need anything else for now, so this is just fine. 01:43.720 --> 01:45.880 Let's go to the game manager. 01:45.880 --> 01:47.380 We need to open the script. 01:47.380 --> 01:49.480 Or actually, let me show you something. 01:49.570 --> 01:50.170 Over here. 01:50.170 --> 01:54.370 We have reference to the player, but when player dies. 01:56.170 --> 02:00.520 This reference is missing, so we need to refill this reference as well. 02:01.480 --> 02:02.920 Let's go back to script. 02:05.070 --> 02:06.870 And over here I'm going to do header. 02:09.310 --> 02:10.210 Player. 02:10.210 --> 02:11.890 Then we need serialize field. 02:11.890 --> 02:13.330 Private GameObject. 02:18.070 --> 02:19.870 I'm going to name it player. 02:21.940 --> 02:22.690 Prefab. 02:22.690 --> 02:26.290 So we have prefab of a player and we can respawn him. 02:28.730 --> 02:29.840 Then we need to realize. 02:29.840 --> 02:30.320 Field. 02:30.320 --> 02:30.830 Private. 02:30.830 --> 02:31.790 Transform. 02:32.540 --> 02:37.670 Respawn point, so we know position where a player should be after he responds. 02:37.880 --> 02:42.830 Now let's go ahead over here and make a public void. 02:42.830 --> 02:47.480 Respawn player and inside we need to do GameObject. 02:47.630 --> 02:56.420 New player equals to instantiate player prefab, add respawn point, dot position. 02:56.420 --> 03:02.000 And we don't need to type dot transform here because respawn point is a transform itself. 03:02.570 --> 03:04.580 And then we're not going to change rotation. 03:04.580 --> 03:06.920 So it's going to be quaternion dot identity. 03:07.810 --> 03:08.770 Very nice. 03:08.770 --> 03:13.390 Now, as you remember, I said that we need to refill this parameter over here because we're going to 03:13.390 --> 03:15.190 use it later on in different places. 03:15.190 --> 03:23.890 So one of the ways to do that would be to change this game object to just player over here. 03:25.250 --> 03:25.460 Oh. 03:25.460 --> 03:26.330 I'm sorry. 03:27.230 --> 03:28.040 Just like that. 03:28.040 --> 03:31.010 So now this reference is this reference. 03:31.010 --> 03:32.810 And we're going to instantiate the object. 03:32.810 --> 03:35.000 But this one is a game object. 03:36.110 --> 03:40.040 But nevertheless we can type dot get component. 03:41.300 --> 03:49.130 Of a player and it would create an object, and also it would get component and assign it to this variable 03:49.130 --> 03:50.030 over here. 03:50.030 --> 03:51.440 But I don't like it. 03:51.440 --> 03:55.970 I don't like to do it this way because it's kind of, I would say cluttered. 03:56.000 --> 03:57.920 I want it to be more readable. 03:57.920 --> 04:01.160 That's why I'm going to do this. 04:01.850 --> 04:06.230 I'm going to make it as a GameObject new player. 04:06.230 --> 04:10.460 And then I'm going to do player equals to new player. 04:11.600 --> 04:14.480 Get component of a player and that's it. 04:14.480 --> 04:16.340 This is very nice and very clean. 04:17.580 --> 04:21.510 Now let's save this and let's go to Dead Zone. 04:22.080 --> 04:29.190 And over here, after we die, we're going to do game manager dot instance respond player. 04:29.190 --> 04:30.180 Just that. 04:30.180 --> 04:33.120 Now let's go ahead and see how does this work. 04:34.260 --> 04:36.240 Oh, sorry, I forgot to do something. 04:37.220 --> 04:41.570 We need to take this start point, move it to respawn point over here. 04:41.630 --> 04:44.720 Also, maybe let's take Game Manager and move it all the way above. 04:45.140 --> 04:49.700 Then we need to go to assets prefab and we need to make prefab of a player. 04:49.700 --> 04:51.470 We can just drag it like so. 04:53.680 --> 04:58.210 Then on a game manager, we're going to take the prefab and give it over here. 04:58.780 --> 04:59.650 Very cool. 04:59.680 --> 05:04.540 Now let's go to the game mode and let's just jump into a dead zone. 05:04.540 --> 05:07.780 And we have a new player every time we die. 05:08.560 --> 05:09.790 Very cool. 05:10.620 --> 05:14.730 Now I want to make it a bit prettier because I don't like how it looks right now. 05:14.730 --> 05:19.680 One of the ways to do that would be to add a delay for eastbound. 05:20.560 --> 05:23.500 So let's make a variable serialized field. 05:23.500 --> 05:24.790 Private float. 05:24.790 --> 05:25.810 Respond. 05:25.810 --> 05:26.590 Delay. 05:28.020 --> 05:39.390 Then we're going to go over here and make a private I enumerator respawn CoroCoro coroutine. 05:39.390 --> 05:46.230 And over here we're going to do yield return new wait for a seconds of respawn delay. 05:46.440 --> 05:48.600 And then we're going to take these two lines of code. 05:48.600 --> 05:49.620 Cut them out. 05:50.740 --> 05:52.240 And place them in here. 05:52.540 --> 05:55.300 And this method would only start a coroutine. 05:56.720 --> 05:58.430 Startcoroutine. 05:58.460 --> 05:59.450 Respawn. 05:59.450 --> 06:00.440 Coroutine. 06:00.590 --> 06:03.830 So now we respawning player with a coroutine. 06:04.400 --> 06:08.630 But this coroutine is private, so we cannot call it outside of a script. 06:08.870 --> 06:12.950 That's why we have this public method that is called respawn player. 06:12.950 --> 06:15.800 And this method will start a coroutine. 06:15.830 --> 06:18.170 Now let's go ahead and check the delay. 06:20.310 --> 06:23.190 I'm going to give it a value of 1.5 seconds. 06:23.190 --> 06:25.410 That's, uh, good enough, I think. 06:25.950 --> 06:27.360 And you. 06:28.330 --> 06:29.440 You okay? 06:29.440 --> 06:30.430 Very cool. 06:30.460 --> 06:32.980 Now let's make visuals for the respawn. 06:32.980 --> 06:38.200 This time we do need to instantiate any visual effect because I have a better way. 06:38.230 --> 06:39.730 We're going to go to assets. 06:39.940 --> 06:41.110 Uh, sorry. 06:41.110 --> 06:45.490 We're going to go to Players Animator and we're going to create new clip. 06:45.880 --> 06:49.330 Then we're going to go to Animations Folder Player. 06:49.330 --> 06:52.600 And over here we're going to do player respawn. 06:53.600 --> 06:54.350 Nice. 06:54.350 --> 06:55.790 Now let's save it. 06:57.980 --> 07:05.330 We're going to go to graphics main character, take this appearance sprites and place them over here. 07:05.330 --> 07:07.310 Sample rate will be 20. 07:09.530 --> 07:10.100 Yeah. 07:10.100 --> 07:11.060 Very cool. 07:11.060 --> 07:17.000 And on the animator, we're going to take this newly created animation and we're going to click right 07:17.000 --> 07:19.490 button and choose Set Default. 07:21.900 --> 07:28.530 Now this is a default animation that is played when object is created or, you know, just starting 07:28.530 --> 07:29.490 the life cycle. 07:29.490 --> 07:32.610 And from here we're going to make transition to idle move. 07:33.470 --> 07:35.540 With an exit time one. 07:36.960 --> 07:39.120 Transition duration zero. 07:40.060 --> 07:40.780 Okay. 07:40.780 --> 07:44.650 Now let's go back to Game Window. 07:44.650 --> 07:47.230 And we can see this effect at the start. 07:47.530 --> 07:49.180 And even when I die. 07:50.530 --> 07:51.370 It is there. 07:51.370 --> 07:58.510 The only issue is that I don't really like how he's affected by gravity and how he can move while he's 07:58.510 --> 08:00.910 respawning, just in that animation. 08:00.910 --> 08:02.230 So I want to fix it. 08:02.230 --> 08:03.700 You're going to go to player. 08:04.630 --> 08:11.290 Over here, and let's make some sort of a method that says, actually, I think we can just make a method 08:11.290 --> 08:14.890 that would say something like respawn is finished or not. 08:14.920 --> 08:16.210 Just simple as that. 08:16.240 --> 08:16.900 What do we need to do? 08:16.900 --> 08:17.740 Let's do it. 08:17.830 --> 08:21.160 I'm going to go ahead somewhere here. 08:22.230 --> 08:27.450 And I want to make a boolean that would say if I can move, we already have is knocked, but I don't 08:27.450 --> 08:31.500 want to use is knocked for the respawn because it just has a different name. 08:31.500 --> 08:33.930 So it can be very confusing why it is there. 08:33.930 --> 08:37.380 I'm just going to go ahead over here and make a private bool. 08:38.480 --> 08:40.640 Can be controlled. 08:41.560 --> 08:43.450 Maybe even I'll place it above. 08:43.450 --> 08:44.200 Just like so. 08:44.200 --> 08:44.860 Yeah. 08:45.040 --> 08:48.310 And by default it's going to be false. 08:49.740 --> 08:51.750 Let's save this then. 08:51.750 --> 08:58.080 Let's go ahead and below the update I'm going to do public void respawn finished. 08:58.440 --> 09:03.300 And inside of this method we want to check if it is finished or not. 09:03.300 --> 09:07.590 And actually instead of checking we can pass the value into the parentheses. 09:07.590 --> 09:10.620 Let's just type away here bool finished. 09:10.620 --> 09:14.880 And now whenever we call this method we can just pass boolean through. 09:14.880 --> 09:16.920 The parentheses could be something like this. 09:16.920 --> 09:22.140 Respawn finished true or respond finished false. 09:22.140 --> 09:24.510 And this value would be passed over here. 09:24.510 --> 09:28.500 And now we can use this value over here as a local variable. 09:28.500 --> 09:29.550 Very cool. 09:31.140 --> 09:38.280 I want to make a float gravity scale and I would make it equals to arb gravity scale. 09:38.760 --> 09:40.260 We're just going to save the value. 09:40.500 --> 09:42.510 Then over here I'm going to do. 09:42.510 --> 09:52.770 If finished then ARB gravity scale equals to gravity scale and can be controlled equals to true. 09:52.770 --> 09:53.670 Else. 09:54.850 --> 09:56.110 We're going to do. 09:56.890 --> 10:02.350 Our big gravity scale equals to zero can be controlled, equals to false. 10:03.380 --> 10:04.400 Just like that. 10:05.930 --> 10:09.530 And then over here before is knocked. 10:09.530 --> 10:15.410 We're going to do if can be controlled equals to false then return. 10:15.680 --> 10:16.640 Simple as that. 10:16.640 --> 10:20.000 Also it would be a good idea to disable Collider I guess. 10:20.000 --> 10:23.870 So we don't get knocked while we respawn in just in case. 10:23.870 --> 10:25.190 So. 10:26.040 --> 10:26.550 Yeah. 10:26.550 --> 10:31.590 Let's go ahead over here and get private Capsule Collider 2D. 10:31.590 --> 10:33.060 I'm going to call it CD. 10:35.100 --> 10:42.120 Then in the awake we're going to do CD equals to get component of a capsule collider 2D. 10:43.630 --> 10:45.100 Then. 10:45.610 --> 10:46.060 I'm sorry. 10:46.060 --> 10:46.960 That was too quick. 10:46.960 --> 10:47.170 Yeah. 10:48.120 --> 10:48.930 Just like that. 10:50.460 --> 10:52.800 Then inside of this method I would do. 10:54.000 --> 10:57.330 I CD enabled, we can disable a component. 10:57.690 --> 10:58.740 Equals to true. 10:58.740 --> 11:02.670 And over here it would be CD enabled equals to false. 11:03.300 --> 11:04.170 Very nice. 11:04.170 --> 11:05.910 Now we have a goal. 11:05.910 --> 11:12.360 We need to call this method at the beginning of the respawn animation and set it to false. 11:12.360 --> 11:16.530 And then oh by the way, this would not work. 11:16.980 --> 11:18.600 This would not work. 11:18.960 --> 11:19.410 Um. 11:20.400 --> 11:21.030 Yeah. 11:21.510 --> 11:23.280 We need to do something else here. 11:23.310 --> 11:27.150 Let's go and make private float. 11:27.180 --> 11:29.970 Default gravity scale. 11:30.000 --> 11:31.950 I'll just place it into a movement. 11:32.070 --> 11:32.490 Yeah. 11:32.490 --> 11:33.900 We cannot make local variable. 11:33.900 --> 11:35.520 I'm going to quickly explain why. 11:37.830 --> 11:38.880 Over here. 11:38.880 --> 11:42.420 First we would call it with a value of false over here. 11:42.420 --> 11:43.080 Yeah. 11:43.080 --> 11:44.190 And. 11:46.000 --> 11:50.200 If we do that, we're going to say our gravity scale equals to current gravity scale. 11:50.200 --> 11:53.320 And next time we call this method with a value of. 11:54.040 --> 11:54.790 True. 11:56.050 --> 12:01.570 This value would be reassigned again, because this is called in the beginning of the method, and because 12:01.570 --> 12:08.680 we have our great scale zero because we set it to zero when it was false, this would assign it to zero, 12:09.160 --> 12:12.130 and then this value would be used over here as a zero. 12:12.160 --> 12:12.580 Yes. 12:12.580 --> 12:14.920 So we cannot do a local variable. 12:15.070 --> 12:16.390 We need to. 12:17.620 --> 12:18.310 Do. 12:19.120 --> 12:21.250 Default gravity scale over here. 12:23.100 --> 12:24.150 Very nice. 12:24.150 --> 12:26.880 Now we can go to the start method. 12:26.880 --> 12:28.230 We don't have a start method. 12:28.230 --> 12:29.160 We're going to make it. 12:30.040 --> 12:35.080 And in the start I'm going to do default gravity scale equals to ARB gravity scale. 12:35.080 --> 12:40.060 And then I would do respawn finished false. 12:40.060 --> 12:43.870 So this would just give it default values. 12:43.870 --> 12:46.420 So this will just uh sorry. 12:46.420 --> 12:47.230 Let's just. 12:47.850 --> 12:48.720 Do it like so. 12:48.720 --> 12:49.260 Yeah. 12:49.590 --> 12:55.320 So because I'm calling this method with a false false value will be passed over here because of that, 12:55.320 --> 12:59.970 this if statement will not work and else statement will work. 12:59.970 --> 13:03.990 And over here we're going to set gravity scale to zero can be controlled false. 13:03.990 --> 13:05.880 Collider enabled false. 13:07.430 --> 13:10.580 So because of that, player is not going to fall. 13:10.580 --> 13:15.140 He's just going to stand in the air and he will be invincible for some time. 13:15.140 --> 13:15.980 Right. 13:15.980 --> 13:17.420 Let's go and try this. 13:17.870 --> 13:19.940 I'm going to go to play mode and. 13:21.240 --> 13:22.530 I cannot control it. 13:26.420 --> 13:27.350 Very cool. 13:27.350 --> 13:29.240 And also Collider is disabled. 13:29.240 --> 13:29.990 Yes. 13:29.990 --> 13:38.360 Now we have a goal to call this method over here with the value true whenever we are ready and we can 13:38.360 --> 13:41.210 do it with the animation trigger, right? 13:41.210 --> 13:42.590 We could go to. 13:43.920 --> 13:45.690 Animator animation. 13:45.690 --> 13:47.880 Find this player. 13:47.880 --> 13:50.280 Respawn and. 13:52.240 --> 13:52.930 In the end. 13:52.930 --> 13:55.690 Over here, we can add an event. 13:57.310 --> 14:03.130 The only problem is we cannot add event to this game object from a player. 14:03.520 --> 14:09.940 Events are available only when script and animator are on the same game object, just like we have with 14:09.940 --> 14:11.170 a visual effect. 14:12.360 --> 14:13.230 Over here. 14:13.230 --> 14:19.890 We have animator and script together, and that's why this animator on this object can call method from 14:19.890 --> 14:20.760 this script. 14:20.760 --> 14:24.870 But over here, this one has no script and this one has no animator. 14:24.870 --> 14:29.670 So we cannot just directly call method on this animator from this script. 14:29.670 --> 14:30.630 But. 14:31.480 --> 14:33.040 We can go to scripts. 14:34.150 --> 14:37.990 And make new C sharp script player. 14:37.990 --> 14:40.180 Animation events. 14:45.070 --> 14:48.190 So over here I have player animation events. 14:49.190 --> 14:51.410 Now I'm going to type private player. 14:51.410 --> 14:52.400 Player. 14:53.690 --> 14:54.920 In their wake. 14:54.920 --> 15:00.230 I'm going to get player equals to get component in parent of a player. 15:01.680 --> 15:05.760 And this will get a variable player in the parent. 15:05.760 --> 15:06.810 We can go back. 15:08.470 --> 15:12.070 And just go to play mode and see it in a debug window. 15:12.070 --> 15:12.970 Animator. 15:12.970 --> 15:15.040 Sorry, we need to put the script on. 15:15.310 --> 15:16.900 Let's put the script. 15:17.550 --> 15:19.050 Then let's go to play mode. 15:21.650 --> 15:22.490 Debug. 15:22.490 --> 15:25.430 And over here I have player reference. 15:26.000 --> 15:26.990 Very cool. 15:27.050 --> 15:29.180 Now we can go back to this one. 15:29.920 --> 15:31.780 Uh, player animation events. 15:33.370 --> 15:45.700 And I'm going to make an event public void finish respawn which would do just player finish player respawn. 15:45.700 --> 15:46.360 Finished. 15:46.360 --> 15:47.020 True. 15:47.560 --> 15:52.420 So this script will call method from a player which would finish respawn. 15:52.420 --> 15:57.040 And we're going to call this method on the event that will do the job for us. 15:57.070 --> 15:59.620 Okay, let's go back to unity. 16:02.050 --> 16:03.010 On the animator. 16:03.010 --> 16:05.500 Let's switch to normal mode. 16:06.450 --> 16:09.750 And then we're going to find player respawn. 16:09.750 --> 16:15.030 And at this event over here we're going to do player animation events method. 16:15.700 --> 16:16.090 Finish. 16:16.090 --> 16:16.750 Respond. 16:17.410 --> 16:21.070 Now let's select the player and apply overrides. 16:22.460 --> 16:23.810 And let's go to play mode. 16:26.780 --> 16:27.920 I'm going to jump. 16:30.530 --> 16:31.340 Very cool. 16:31.340 --> 16:36.920 I cannot be controlled while I am respawning, but I can be controlled after and I'm falling only when 16:36.920 --> 16:37.550 I'm ready. 16:37.550 --> 16:39.020 I think this is a cool effect. 16:39.020 --> 16:40.160 I like it a lot. 16:46.210 --> 16:50.710 Well, this is good for now and I'll see you in the next video.
