WEBVTT 00:00.000 --> 00:00.480 Hello guys. 00:00.480 --> 00:01.440 Welcome to the video. 00:01.440 --> 00:04.560 In this one we need to work on a co-op camera. 00:04.560 --> 00:08.370 This means we will have to adjust the camera system quite a bit. 00:08.370 --> 00:11.280 It may take long, maybe 15 to 20 minutes. 00:11.280 --> 00:12.120 I'm not sure. 00:12.120 --> 00:13.620 The testing took a lot. 00:13.620 --> 00:14.880 So yeah, this. 00:14.880 --> 00:16.200 What are we going to do in this video? 00:16.200 --> 00:17.520 What the goal is. 00:17.520 --> 00:18.900 Let's define the goal. 00:18.900 --> 00:22.740 Our goal is to fit both players in the camera's view. 00:22.740 --> 00:25.710 Also, we want it to be a bit dynamic and active. 00:25.710 --> 00:29.190 And also we have a goal of making the camera follow one of the players. 00:29.190 --> 00:34.200 If only one of the players are in the game right now, and then when there is two players in the game, 00:34.200 --> 00:39.570 like when second player join in the game, then we need to center a camera between two players. 00:39.570 --> 00:45.810 And also if two players are going too far from each other, we want to zoom out the camera so it can 00:45.810 --> 00:48.570 see entire level and both players as well. 00:48.840 --> 00:50.610 Okay, that sounds like a lot. 00:50.610 --> 00:51.780 It's kind of a lot. 00:51.780 --> 00:54.090 So let's get to business, okay. 00:55.450 --> 01:02.740 First of all, we want to go ahead to this camera trigger and we want to disable these lines of code 01:02.740 --> 01:07.450 over here just for now, because they will enable and disable camera whenever they want. 01:07.450 --> 01:08.500 And we do need to do that. 01:08.500 --> 01:11.290 As of now we want to have manual control of everything. 01:11.560 --> 01:15.670 Also let's go to level camera and let's comment out this one. 01:16.790 --> 01:17.750 Very good. 01:17.780 --> 01:21.980 Now, first, uh, let's do something simple. 01:21.980 --> 01:24.050 Let's zoom out the camera. 01:24.050 --> 01:29.270 When players are getting too far from each other, or if, to be precise, when they getting out of 01:29.270 --> 01:30.650 the view of the camera. 01:31.190 --> 01:34.820 Uh, to show you what I mean by that, I'm going to make. 01:35.690 --> 01:41.360 An object camera center point, and it's going to be exactly in the center of the level. 01:41.420 --> 01:42.980 Now let's go to play mode. 01:45.280 --> 01:47.170 I'm gonna make two players. 01:48.880 --> 01:53.200 And let me take the camera and zoom in, maybe like eight. 01:54.260 --> 01:55.190 And let me make it. 01:55.190 --> 01:57.260 Follow the camera center point. 01:57.960 --> 01:58.620 Okay. 02:00.130 --> 02:02.110 So this is the center point. 02:02.440 --> 02:09.460 And let's say one player goes here, he exits the area and second player goes somewhere here. 02:10.530 --> 02:11.970 Right there. 02:11.970 --> 02:13.440 I cannot get there anyway. 02:13.440 --> 02:19.470 Now we want to zoom out the camera so both of them will stay in the view of the camera inside of the 02:19.470 --> 02:20.070 frame. 02:20.070 --> 02:21.540 How could we achieve that? 02:21.540 --> 02:24.540 Well, I found a solution, I guess. 02:24.540 --> 02:29.040 And before I show you that, I want to let you know that there is a component that's supposed to take 02:29.040 --> 02:34.860 care of this, you can go to extensions over here and there is a group framing, but I do not like how 02:34.860 --> 02:36.360 it works for me. 02:36.360 --> 02:38.820 I feel like it's moving too much. 02:38.820 --> 02:41.850 It just always shakes here and there, left and right. 02:42.770 --> 02:48.470 And there are not many parameters to set up this thing, so I prefer to use custom solution that is 02:48.470 --> 02:50.420 more suitable for our game. 02:50.420 --> 02:51.680 This is what we're going to do. 02:51.710 --> 02:53.660 We're going to make a new script. 02:54.920 --> 02:57.380 Level camera view. 03:00.040 --> 03:02.920 And we want to put Collider on the camera. 03:04.640 --> 03:09.860 Box Collider 2D and let's make it is trigger over here. 03:10.310 --> 03:15.590 Now let's adjust the size of a trigger, and it's going to be the frame that player are supposed to 03:15.590 --> 03:18.410 be in before we change the view. 03:18.530 --> 03:23.780 Let's say it's going to be 27 on the X and 18 on the Y. 03:25.410 --> 03:27.840 I know because I tried, so I know the values. 03:27.930 --> 03:32.850 Let's give offset on the y 2.2 and I want to see the box size. 03:32.880 --> 03:34.650 Um looks okay. 03:34.650 --> 03:36.240 Let's just try with this box size. 03:36.240 --> 03:37.860 Then we can adjust it if we want to. 03:37.890 --> 03:39.810 Now the goal is very simple. 03:39.870 --> 03:43.470 We want to go to the script of Level camera view. 03:43.470 --> 03:46.440 Let's put it on the cinemachine camera over here. 03:46.920 --> 03:47.520 And inside. 03:47.520 --> 03:52.770 We want to keep track of how many players are in the trigger at the moment, and if they're in the trigger, 03:52.770 --> 03:54.450 it means they're in the camera view. 03:55.200 --> 04:02.460 Okay, we could theoretically make the box size of a collider according to the size of the lens on the 04:02.460 --> 04:05.430 cinemachine, but I think it's an overkill. 04:05.430 --> 04:06.390 I don't really want to do it. 04:06.390 --> 04:07.830 I'll just do manual setup. 04:08.780 --> 04:11.000 So let me take the camera trigger. 04:11.000 --> 04:13.610 I want to take these methods from here. 04:13.610 --> 04:16.460 I'm going to copy go to Level Camera view. 04:16.460 --> 04:18.710 Paste this in over here. 04:19.820 --> 04:24.650 And then we need a variable just like we did in the last video private int. 04:25.350 --> 04:27.540 Players in view. 04:28.780 --> 04:32.650 Then over here we're going to do players in view Plus plus. 04:32.650 --> 04:40.240 And if players in view is bigger or equals to level camera and we need player list here. 04:40.240 --> 04:45.010 So I'm going to yeah we need player list here to know how many players there are supposed to be. 04:45.430 --> 04:47.500 Well as of now let's use player manager. 04:47.530 --> 04:48.190 All right. 04:48.980 --> 04:51.320 I'm going to do player manager instance. 04:51.320 --> 04:52.490 Get player list. 04:53.000 --> 04:54.020 What's up with you? 04:55.200 --> 04:56.910 Now we need to do dot count. 04:56.910 --> 05:02.760 So if players in view are the same amount as it's supposed to be, we can decrease the size of the lengths. 05:02.760 --> 05:04.770 We can take a closer look at the players. 05:04.770 --> 05:07.800 So we need to decrease size of lens. 05:08.310 --> 05:12.960 Then on the exit we want to do players in view minus minus. 05:12.960 --> 05:19.260 And if players in view is less than player manager dot instance get player list. 05:20.110 --> 05:21.190 Dot count. 05:21.310 --> 05:24.460 Then we need to, uh, zoom out the camera. 05:24.460 --> 05:26.560 So we need to increase the lens size. 05:27.520 --> 05:35.740 Increase the lens size, and we could directly do level camera cinemachine and increase the lens size, 05:35.740 --> 05:37.330 but that would be too snappy. 05:37.330 --> 05:40.300 I want to have a smooth change of value. 05:40.300 --> 05:46.480 That's why we're going to go to level camera and make a method that may look complicated, but actually 05:46.480 --> 05:47.590 it's super simple. 05:47.590 --> 05:48.220 All right. 05:49.100 --> 05:55.160 Let's go ahead and make a value private float target lens size. 05:55.160 --> 05:59.330 And I want to make it, uh, a serialized field because I want to show you how it works. 05:59.810 --> 06:01.490 Then in the. 06:02.420 --> 06:10.460 We're going to open up the gate and below let's make a method private void update lens size if needed. 06:10.670 --> 06:17.150 Okay, now inside of this method we want to check what is the current lens size we want to do. 06:17.150 --> 06:24.530 Float current lens size equals to Cinemachine lens orthographic size. 06:27.180 --> 06:28.680 Now we have current land size. 06:28.680 --> 06:33.090 We want to check if, uh, it is different from a target land size. 06:33.090 --> 06:38.520 We can do that by just checking the difference and seeing if this difference is bigger than very small 06:38.520 --> 06:38.910 value. 06:38.910 --> 06:44.730 Also, if we just take the difference between two values, it's going to be either negative or positive. 06:44.730 --> 06:47.610 But we want this check to work for both cases. 06:47.610 --> 06:54.870 For that we need to take math F absolute math f absolute absolute will always return you a positive 06:54.870 --> 06:55.230 value. 06:55.230 --> 06:56.970 And that is just perfect for us. 06:56.970 --> 07:02.340 Let's open a parenthesis and do current land size minus target land size. 07:02.340 --> 07:09.000 And if positive value of the difference is bigger than 0.5 f, it means it is different and we need 07:09.000 --> 07:10.920 to bring them closer to each other. 07:10.920 --> 07:16.800 If to be precise, we want to change land size and make it equals to target land size. 07:16.800 --> 07:19.800 We can do that smoothly with the help of a lerp. 07:19.800 --> 07:21.030 We're going to do float. 07:21.030 --> 07:30.570 New lens size equals to math f dot lerp from current land size to a target lens size. 07:30.570 --> 07:39.210 And let's do time step of 0.5 f, multiply it by time dot delta time so it will be smooth and nice. 07:39.270 --> 07:44.370 And then we want to take cinemachine lens orthographic size equals to new lens size. 07:44.370 --> 07:48.270 And because of that it's going to smoothly increase or decrease the lens size. 07:48.270 --> 07:48.870 You'll see. 07:48.870 --> 07:54.630 Now also if difference is not very big, like if difference is very small, then we can just snap it 07:54.630 --> 07:56.280 to the value that we want to have. 07:56.280 --> 08:03.180 Cinemachine lens orthographic size equals to target lens size. 08:03.420 --> 08:06.570 Okay, now let's update this value in the update. 08:07.650 --> 08:09.810 Update lens size if needed. 08:09.810 --> 08:13.170 I'm going to save it and I want to go to update. 08:13.170 --> 08:15.660 I mean to unity and show you how it works. 08:15.660 --> 08:18.120 Now we're going to go to Level Camera. 08:20.490 --> 08:24.780 And let's say we know the land size now is nine, or actually it is ten. 08:24.780 --> 08:26.340 Let's make it as nine. 08:28.370 --> 08:29.090 And over here. 08:29.090 --> 08:31.220 Target lenses by default is nine. 08:31.760 --> 08:33.230 Now let's go to play mode. 08:35.670 --> 08:38.760 And we can see camera is not moving, everything is fine. 08:38.760 --> 08:42.120 And if we change the target value to ten. 08:43.430 --> 08:45.650 It's going to zoom out just like that. 08:45.650 --> 08:48.740 If you change target value to lower like five. 08:48.770 --> 08:50.120 It's going to zoom in. 08:50.120 --> 08:55.250 So this allows you to have method that changes zoom of the camera when you want to. 08:57.050 --> 09:02.870 And now we can just change this value through the method to make camera zoomed in or zoomed out. 09:02.870 --> 09:07.250 And that will depend on the amount of players we have in the camera's view. 09:08.040 --> 09:12.420 Let's make a method public void change camera. 09:13.560 --> 09:15.090 Lens size. 09:15.090 --> 09:20.940 We're going to pass a float size and we're going to do target lens size equals to size. 09:23.040 --> 09:23.760 Nice. 09:23.760 --> 09:26.100 Now let's go back to this level camera view. 09:26.700 --> 09:30.360 And over here we want to change value to uh. 09:31.230 --> 09:32.250 Different one. 09:32.250 --> 09:36.330 Well, we can hard code the value or we can make a variable. 09:36.840 --> 09:39.750 That is up to you I think. 09:39.750 --> 09:39.930 Yeah. 09:39.930 --> 09:41.850 Let's do variables on a level camera. 09:44.410 --> 09:51.490 Let's make public float mean camera size and public float max camera size. 09:51.610 --> 09:52.690 Now I'm going to save it. 09:52.690 --> 09:54.910 And I'm going to go back to level Camera view. 09:55.270 --> 09:57.340 And over here we're going to do level camera. 09:59.380 --> 10:02.590 Change camera lens size to level camera. 10:03.220 --> 10:04.840 And here we zoom in in. 10:04.840 --> 10:07.420 So I'm going to do mean camera size. 10:08.020 --> 10:15.880 Over here we're going to do level camera change camera lens size to level camera max camera size okay. 10:15.880 --> 10:17.200 This is supposed to work. 10:17.200 --> 10:20.440 Let me remove this and let's go ahead and try this. 10:25.910 --> 10:27.770 Oh, I forgot to change values. 10:28.810 --> 10:30.880 Let's do a minimum camera size nine. 10:30.880 --> 10:32.740 Maximum camera size ten. 10:33.250 --> 10:35.200 Also, we don't need to see this value anymore. 10:35.200 --> 10:36.340 We know how it works. 10:36.340 --> 10:39.490 So I'm going to go back here I'm going to hide it. 10:40.700 --> 10:44.900 And just in case, I'm going to go to awake and I'm going to do target lens size. 10:46.780 --> 10:51.070 Equals to um cinemachine lens. 10:51.310 --> 10:52.390 Orthographic size. 10:52.390 --> 10:56.350 So by default it will take value that we have on the camera at the moment. 10:56.380 --> 10:56.830 Okay. 10:56.830 --> 10:58.690 So we don't have to change it every time. 11:01.060 --> 11:02.560 Now I'm going to go to play mode. 11:04.760 --> 11:06.770 Camera will look in the center. 11:07.160 --> 11:12.320 I will add the player and then I'll try to walk out of the area. 11:12.590 --> 11:14.210 The area is. 11:14.810 --> 11:15.590 Where is it? 11:16.560 --> 11:18.780 The area is over here. 11:18.780 --> 11:21.840 This is the collider that is barely visible and I'll try to. 11:22.900 --> 11:24.460 Jump out of that area. 11:26.940 --> 11:27.990 I cannot jump there. 11:27.990 --> 11:33.570 Well, I can go here and we can see that camera is zooming out slowly, which is very nice and very 11:33.570 --> 11:34.200 pretty. 11:34.230 --> 11:38.880 Now I'm going to go back and we zooming in so we can see both players. 11:39.670 --> 11:40.810 Very cool, I love it. 11:40.810 --> 11:42.520 Let me try to work out again. 11:43.990 --> 11:45.220 And we zoom in out. 11:45.250 --> 11:46.630 It feels a bit snappy. 11:47.350 --> 11:49.180 I wonder why it should be smooth. 11:49.210 --> 11:52.180 Maybe just because of the structure of the level. 11:52.180 --> 11:54.430 Well, it doesn't really matter because we're going to adjust it more. 11:54.430 --> 11:58.330 And that will fix the problem with the shaking over there like we see right now. 11:59.890 --> 12:01.780 Okay, so what is the next goal? 12:02.200 --> 12:05.170 Now we cannot keep camera just in the center like that. 12:05.170 --> 12:07.300 I want it to be a bit dynamic. 12:07.300 --> 12:08.680 I want it to move around. 12:09.580 --> 12:11.620 And for that we can place camera. 12:12.420 --> 12:16.530 Center between two points if there are two players in the game. 12:16.830 --> 12:18.270 If we want to do that. 12:19.310 --> 12:26.240 We need to go to level camera, and we need to check how many players there are in the game right now. 12:28.090 --> 12:34.120 Um, we can make a private list of player. 12:37.620 --> 12:39.060 Player list. 12:39.730 --> 12:42.910 And let's let's maybe make it public. 12:44.080 --> 12:47.050 Public yet private set. 12:50.040 --> 12:54.480 Now we can use this list on a level camera view over here instead of player manager. 12:55.820 --> 12:59.270 Mobile camera player list dot count. 12:59.270 --> 13:00.560 Same goes here. 13:04.180 --> 13:06.730 The on camera player list count. 13:07.150 --> 13:07.990 Nice. 13:08.110 --> 13:11.380 And then let's go to level camera and adjust it slightly. 13:15.370 --> 13:18.520 First of all, we want to have the center point. 13:19.940 --> 13:21.950 So I'm going to make satellites field private. 13:21.980 --> 13:25.520 Transform camera center point. 13:25.520 --> 13:28.430 And this is the point we're going to place between two players. 13:28.550 --> 13:32.720 Now let's go and make a method that would update camera status. 13:32.720 --> 13:38.510 And we can update camera status every time player joins or disconnects from the game. 13:38.870 --> 13:41.240 I'm going to make a method over here. 13:42.400 --> 13:49.030 Private void update camera status in which we want to update, uh, list. 13:49.030 --> 13:52.270 So I'm going to do player list equals to player manager. 13:52.270 --> 13:54.910 That instance get player list. 13:54.910 --> 14:01.630 Then we want to see if player list count is bigger than one, means we have more than one player in 14:01.630 --> 14:02.200 the game. 14:02.200 --> 14:06.010 And if that's the case then we want to focus camera on a center point. 14:06.010 --> 14:09.430 I'm going to set new target camera center point. 14:09.580 --> 14:11.620 Also you can see we have a misspelling over there. 14:11.620 --> 14:12.790 So I'm going to fix it. 14:15.940 --> 14:20.680 Then else means if we don't have more than one player in the game, we're going to focus camera on the 14:20.680 --> 14:22.240 first player in the list. 14:22.240 --> 14:28.270 Set new target layer list with a zero dot transform very well. 14:28.420 --> 14:30.700 So this will update the camera status. 14:30.700 --> 14:32.410 We just need to call this method. 14:33.150 --> 14:36.270 Uh, like at the right moment of the game. 14:37.150 --> 14:40.990 I think it's better to do this when player dies or respawns. 14:40.990 --> 14:43.660 So I'm going to go all the way below over here. 14:44.230 --> 14:45.880 And I'm going to do on enable. 14:47.860 --> 14:48.790 Player manager. 14:49.390 --> 14:49.780 Uh. 14:49.780 --> 14:50.620 On player. 14:50.620 --> 14:51.370 Respawn. 14:51.970 --> 14:52.810 Plus equals. 14:52.810 --> 14:53.380 Update. 14:53.380 --> 14:54.640 Camera status. 14:55.620 --> 14:59.820 Player manager on player death update camera status. 14:59.820 --> 15:01.650 Also we need to unsubscribe from this. 15:01.650 --> 15:03.240 So on disable. 15:04.050 --> 15:06.030 Let's take these two lines of code. 15:06.150 --> 15:07.410 Paste them in here. 15:08.630 --> 15:09.140 And do. 15:09.140 --> 15:09.950 Minus. 15:10.310 --> 15:11.240 Minus. 15:11.510 --> 15:14.060 Okay, let's save this. 15:14.390 --> 15:16.040 Uh, let's go back. 15:17.880 --> 15:20.460 And we could call it in the update. 15:20.460 --> 15:22.950 And this supposed to do half of the job. 15:23.460 --> 15:30.150 We also want to find a midpoint between two players and place this center point between two players. 15:34.100 --> 15:36.200 Actually, it's not that difficult to do. 15:36.620 --> 15:39.050 Let's make a method. 15:40.130 --> 15:45.110 Public void update center point position. 15:45.620 --> 15:49.130 And over here we just want to get transform of two players. 15:49.130 --> 15:52.370 Find the midpoint between them and then place camera there. 15:52.370 --> 15:57.500 To do that we need to have reference to players transform and we could get them from the list. 15:57.500 --> 16:02.480 But I want to have a clear variable so we understand what it does and why we use it like that. 16:02.480 --> 16:07.010 So I'm going to do private transform P1 private transform P2. 16:08.250 --> 16:08.640 Let's do. 16:08.640 --> 16:09.630 Player one. 16:10.200 --> 16:11.190 Player two. 16:11.370 --> 16:12.150 Okay. 16:12.360 --> 16:14.520 Now we're going to go to this. 16:14.640 --> 16:21.660 Oh, and also I want to have a boolean that says private bool camera focused on center. 16:23.310 --> 16:24.990 Now let's go to this method. 16:24.990 --> 16:29.190 And if we have more than one player in the game and we updated the list, then we want to do player 16:29.190 --> 16:34.740 one equals to player list zero transform player two player list. 16:35.380 --> 16:39.820 One transform and camera focused on center. 16:39.820 --> 16:40.450 True. 16:40.810 --> 16:43.630 If you don't have the players camera focused on center. 16:43.630 --> 16:44.530 False. 16:44.530 --> 16:45.430 Very nice. 16:45.430 --> 16:48.520 Let's save this and let's go back to this method. 16:48.520 --> 16:53.020 First of all, if camera focused on center is equals to false, we're going to return from here. 16:53.020 --> 16:55.240 So we're not going to update center position. 16:55.240 --> 16:58.960 And if we do then we need to do Vector3 midpoint. 16:58.960 --> 17:01.570 And this will be middle point between two players. 17:01.720 --> 17:04.840 We can easily get it by typing player one. 17:05.880 --> 17:13.200 Dot position plus player two dot position divided by two, and this will give us a middle point between 17:13.200 --> 17:14.250 two objects. 17:14.250 --> 17:19.530 And now we can take a camera center point dot position equals to midpoint. 17:19.530 --> 17:23.310 Now the goal is to update position at all times. 17:23.310 --> 17:26.250 But I think I don't want to do this in the update. 17:27.330 --> 17:28.620 That could be too often. 17:28.620 --> 17:33.210 So let's go to awake over here and let's invoke this method with repeating. 17:33.570 --> 17:35.130 Invoke repeating. 17:35.160 --> 17:40.170 You're going to do name of update camera center point position. 17:41.630 --> 17:42.560 And zero delay. 17:42.560 --> 17:43.610 Repeat rate. 17:44.680 --> 17:45.670 Point one F. 17:46.030 --> 17:48.400 This is pretty often, but not too often. 17:48.460 --> 17:52.090 Okay, so yeah, it was kind of fast. 17:52.090 --> 17:53.380 I'm sorry if it was fast. 17:53.380 --> 17:55.690 I just, you know, I'm going to tell you a secret. 17:55.690 --> 17:59.230 I'm recording this video for the fourth time's. 17:59.230 --> 18:04.990 Yeah, I did try 4 or 5 times and I couldn't get the flow right where I am explaining everything in 18:04.990 --> 18:06.610 a needed and needed order. 18:06.610 --> 18:09.610 So I had to start over again and again. 18:09.610 --> 18:10.270 Again and again. 18:10.270 --> 18:13.420 And that might be why I'm going a little bit fast here. 18:13.420 --> 18:17.890 I hope you can forgive me for that, especially in the end of the course. 18:18.220 --> 18:18.970 Yeah. 18:18.970 --> 18:20.260 By the way, congratulations. 18:20.260 --> 18:21.460 We are finishing up soon. 18:22.460 --> 18:24.080 Now let's go back to unity. 18:24.620 --> 18:27.860 And we have this camera center point over here. 18:27.860 --> 18:30.980 So I'm going to just assign it into this field. 18:30.980 --> 18:32.450 And I want to take center point. 18:32.450 --> 18:35.180 And I want to give it a gizmo so I can see it. 18:35.750 --> 18:37.730 Now this is supposed to do the job. 18:37.730 --> 18:38.930 Let's go to play mode. 18:43.030 --> 18:44.440 There is one player. 18:44.920 --> 18:46.000 Very nice. 18:46.570 --> 18:50.980 It is focused on the player and it feels pretty dynamic, I like it. 18:51.130 --> 18:54.820 Now I'm going to add another player and now camera is between them. 18:54.820 --> 18:58.240 We can enable gizmos and we can see the dot over here. 18:58.300 --> 19:00.730 If I go there and if I. 19:02.320 --> 19:04.060 Maybe jump over the player camera. 19:04.090 --> 19:04.900 Going to be dynamic. 19:04.900 --> 19:07.150 It's going to move to the sides. 19:07.300 --> 19:08.920 Very nice I love it. 19:10.090 --> 19:10.390 And. 19:10.390 --> 19:11.680 Yeah, I got here. 19:11.710 --> 19:16.000 Now, let me try to walk away from the player and it's supposed to zoom out. 19:16.000 --> 19:17.290 Yeah, it did zoom out. 19:17.290 --> 19:18.640 Very nice and clean. 19:18.790 --> 19:20.950 Almost unnoticeable really. 19:20.950 --> 19:23.140 We can see two players in the level. 19:23.140 --> 19:26.380 And if I come closer, it's going to nicely zoom in. 19:28.480 --> 19:35.020 Also, you probably noticed that just now I could see a bit of a, uh, blue background over here. 19:36.710 --> 19:40.310 It may happen sometimes because camera, you know, it's very difficult to manage. 19:40.310 --> 19:41.990 There are so many things considered. 19:41.990 --> 19:47.810 And what you could do is just draw the level around the playable area over here. 19:47.810 --> 19:50.870 Just add some parts to hide it. 19:52.440 --> 19:53.310 Just like that. 19:53.960 --> 19:57.590 Also, you could go to, um. 19:59.140 --> 20:01.600 Main camera over here. 20:01.600 --> 20:07.690 Find the background and take Color Picker and choose background. 20:08.170 --> 20:09.430 Uh, just like this one. 20:09.430 --> 20:10.840 Let's just click it on it. 20:11.840 --> 20:15.950 Okay now in the game, even if you don't have area there. 20:17.600 --> 20:20.180 It will look just like a background of the level. 20:20.210 --> 20:22.160 Let me show you that I'm going to just. 20:24.170 --> 20:26.990 Remove here everything. 20:29.640 --> 20:32.610 Here you can see it looks dark blue, so it's fine. 20:32.610 --> 20:37.230 So if it is outside of the level, it's going to just show you this background and it does not look 20:37.230 --> 20:38.220 like a bug. 20:39.150 --> 20:39.960 Okay. 20:39.960 --> 20:40.890 Very well. 20:42.030 --> 20:42.570 Now. 20:42.570 --> 20:43.770 We did a lot. 20:43.860 --> 20:49.020 I can see it's about 20 minutes now, but we still have to do one more adjustment here. 20:49.020 --> 20:51.180 And to do this adjustment, we better go. 20:51.180 --> 20:53.370 We better go to another level. 20:54.800 --> 20:57.290 Now let's take camera manager level camera. 20:57.290 --> 20:59.240 Let's apply overrides. 21:00.180 --> 21:00.750 Apply. 21:00.750 --> 21:05.220 So now this camera has everything that is needed to make it work. 21:05.220 --> 21:08.190 And we can go to scene level four. 21:08.190 --> 21:09.450 I'm going to save it. 21:09.450 --> 21:12.660 And on this level we have two areas. 21:13.110 --> 21:15.210 Area one and area two. 21:15.240 --> 21:20.910 Now I don't want one of the players to go further without second player joining him. 21:20.910 --> 21:26.250 If there is only one player entered next room, then he's supposed to wait for the first player to enter. 21:26.250 --> 21:28.710 This is what we need to do, how it's going to be. 21:28.710 --> 21:31.140 We're going to place invisible colliders. 21:31.140 --> 21:36.720 The player cannot pass by and we're going to disable this colliders only when two players entered the 21:36.720 --> 21:37.290 room. 21:39.010 --> 21:39.910 The rom rom. 21:39.910 --> 21:40.330 Yeah. 21:40.720 --> 21:44.680 So this one we're going to do we're going to go. 21:47.250 --> 21:48.570 We're going to go. 21:50.400 --> 21:51.540 Let's say here. 21:51.540 --> 21:55.050 Let's make 2D object sprite square. 21:56.610 --> 21:58.770 I'm going to name it as, uh, maybe. 21:59.510 --> 22:01.460 Level limits. 22:01.820 --> 22:06.200 Not sure it's supposed to be under the camera, but this is a pretty good place for it because functionality 22:06.200 --> 22:07.100 going to be here. 22:08.140 --> 22:12.010 And we're going to just take these limits and let's say place it somewhere. 22:13.330 --> 22:14.020 Here. 22:14.230 --> 22:17.770 Let's do player minus one so I can see it. 22:18.100 --> 22:19.450 And I'm going to just. 22:20.370 --> 22:21.990 Make it white like that. 22:23.090 --> 22:25.460 Also let me take checkpoint and move it here. 22:25.940 --> 22:27.560 So now we have this level limit. 22:27.920 --> 22:29.240 It is a collider. 22:29.240 --> 22:35.630 We want to add box Collider 2D here and we want it to be unpassable only for players. 22:35.630 --> 22:37.460 So let's make a layer. 22:39.360 --> 22:40.710 Layers. 22:40.920 --> 22:42.090 Limits. 22:42.540 --> 22:45.360 We're going to go to Edit Project Settings. 22:45.990 --> 22:50.310 And over here we need to disable collision for everything but a player. 22:51.090 --> 22:51.840 Nice. 22:51.840 --> 22:52.920 Gonna close it. 22:54.810 --> 22:57.330 And then we need to go to. 22:57.360 --> 22:57.960 I'm sorry. 22:57.960 --> 22:58.890 I need to think a bit. 22:58.890 --> 23:03.720 We need to go to level camera because I think we can centralize everything and then just call method 23:03.720 --> 23:04.470 from here. 23:04.980 --> 23:06.600 And we want to make array. 23:08.370 --> 23:09.390 Serialize field. 23:09.390 --> 23:10.050 Private. 23:10.900 --> 23:11.890 I'm going to do it here. 23:11.890 --> 23:15.880 Collider 2D array limits. 23:16.390 --> 23:20.200 Then we want to make a method that will disable or enable these limits. 23:21.660 --> 23:22.890 So. 23:23.910 --> 23:24.870 What are we going to do? 23:28.670 --> 23:30.410 Over here we have enable camera. 23:30.440 --> 23:36.170 I'm also going to do a public void enable limits. 23:37.090 --> 23:45.850 Bool enable, then we're going to do for each var collider in colliders are in limits we're going to 23:45.850 --> 23:46.960 do Collider. 23:50.900 --> 23:52.250 Collider enabled. 23:52.250 --> 23:52.910 Enable. 23:55.240 --> 23:57.850 So this one can disable or enable limits. 23:57.850 --> 24:02.920 Also, since we're doing this, let's make a variable that says that camera is enabled. 24:03.280 --> 24:04.180 I'm going to do. 24:05.680 --> 24:05.860 Right. 24:05.860 --> 24:08.950 Red bull camera active maybe like that. 24:08.950 --> 24:13.690 And I want to disable all of the functionality if camera is not active. 24:13.690 --> 24:15.550 So if camera active. 24:16.330 --> 24:21.220 False return then over here as well if camera active. 24:21.220 --> 24:22.060 False. 24:23.500 --> 24:26.080 Return and. 24:28.490 --> 24:29.570 Over here as well. 24:29.570 --> 24:32.960 If camera active polls return. 24:33.410 --> 24:34.130 Nice. 24:36.280 --> 24:37.600 And this one should be okay. 24:37.600 --> 24:38.860 We don't need to update this one. 24:38.860 --> 24:41.800 This one will not be called because we need to return in the update. 24:41.800 --> 24:46.330 We just need to go here and do camera active equals to enable. 24:47.170 --> 24:47.980 Nice. 24:48.070 --> 24:50.440 Now let's go back to level camera trigger. 24:50.440 --> 24:51.790 The one we had before. 24:52.120 --> 24:53.740 It is over here. 24:53.890 --> 24:58.420 And we did enable camera if player entered the area. 24:58.420 --> 24:59.920 And then we disable the camera. 24:59.920 --> 25:02.260 If player exit the trigger. 25:02.260 --> 25:08.920 Now we want to disable the camera only if two players are exiting the trigger or two players entering 25:08.920 --> 25:12.850 the trigger, and actually the amount of players that is supposed to be in the game right now. 25:12.850 --> 25:14.560 So this is what I'm going to do. 25:14.560 --> 25:17.320 I'm going to make private int. 25:18.360 --> 25:20.070 Players in. 25:20.920 --> 25:21.730 Trigger. 25:22.680 --> 25:26.850 Then every time somebody enters the trigger, we're going to do player sin, trigger plus plus. 25:26.850 --> 25:28.830 Then we want to open if statement. 25:28.830 --> 25:34.230 And inside of this if statement we're going to do if player sin trigger is equals to level camera player 25:34.230 --> 25:39.300 list dot count then level camera enable. 25:40.380 --> 25:40.950 Tamara. 25:41.280 --> 25:42.060 True. 25:42.090 --> 25:45.510 Then we need level camera enable limits. 25:45.510 --> 25:49.020 True because we want to block exits out of this room. 25:49.320 --> 25:56.520 Then this one can be removed and we can go over here and do player scene trigger minus, minus. 25:56.520 --> 26:03.090 And then if player since trigger is equals to zero means there is no players in the room anymore, we 26:03.090 --> 26:07.080 can, uh, unlock the doors and we can disable the camera. 26:07.080 --> 26:09.750 So I'm going to do level camera, enable camera. 26:10.620 --> 26:13.320 Balls and level camera enable limits. 26:13.320 --> 26:14.070 False. 26:14.100 --> 26:16.380 Okay, let's save this. 26:16.380 --> 26:20.070 Let's go back to unity. 26:21.350 --> 26:24.560 And I'm going to have a level limit over here. 26:27.230 --> 26:28.730 For this room. 26:28.730 --> 26:33.800 And this one basically means that we cannot exit from here until there is two players on the level. 26:33.800 --> 26:35.180 Okay, that's the idea. 26:38.170 --> 26:41.050 Uh, something like this should be fine. 26:42.400 --> 26:43.120 Okay. 26:43.330 --> 26:47.470 And then for this camera over here, let me duplicate it. 26:48.630 --> 26:49.950 Actually, I think we can just. 26:51.350 --> 26:52.790 Apply overrides. 26:52.820 --> 26:54.500 Now this one has level limit. 26:54.500 --> 26:55.970 I'm going to enable camera. 26:55.970 --> 26:57.530 I'm going to take level limit. 26:57.530 --> 26:59.720 And I'm going to place it over here. 26:59.720 --> 27:01.460 So we cannot go back alone. 27:01.460 --> 27:03.590 We can go back only together. 27:03.590 --> 27:07.370 You getting the point right for this area. 27:07.370 --> 27:12.080 Exit is blocked over here for this area. 27:12.500 --> 27:14.240 Exit is blocked over here. 27:14.240 --> 27:19.580 And if you have more exits, you can just add another game object and assign it into the. 27:20.660 --> 27:21.650 Array over here. 27:21.650 --> 27:23.060 Let me assign it here. 27:23.060 --> 27:25.580 And for this room should be here. 27:26.120 --> 27:26.870 Okay. 27:28.990 --> 27:30.010 Very good. 27:30.040 --> 27:32.500 Now everything's supposed to work. 27:32.500 --> 27:35.110 I think we did pretty much everything that we need. 27:35.110 --> 27:37.210 And let's go and try this. 27:38.160 --> 27:39.150 Can I go to game mode? 27:39.180 --> 27:40.590 Going to go to play mode. 27:40.590 --> 27:42.660 Oh, wait a second, I think I forgot something. 27:42.660 --> 27:47.580 We need to take level limits and we need to change layer to players limit. 27:48.210 --> 27:50.370 Now I'm going to apply overrides again. 27:51.250 --> 27:53.140 Let's enable second camera. 27:54.270 --> 27:55.440 That looks good to me. 27:56.010 --> 27:57.450 Now let's go to play mode. 27:57.840 --> 27:59.910 Also why it is showing this view right now. 28:05.900 --> 28:09.080 Let me do minus one over here so it does not bother me. 28:09.080 --> 28:09.710 Okay. 28:09.710 --> 28:11.300 So it has less priority. 28:11.330 --> 28:13.190 Now let's go to play mode. 28:15.490 --> 28:20.260 I'm going to join the player, and I can see that camera did not focus on the player. 28:20.860 --> 28:21.550 Okay. 28:21.550 --> 28:23.170 Maybe I made a mistake. 28:23.170 --> 28:24.670 Let's go to level camera. 28:27.000 --> 28:27.240 Uh. 28:27.240 --> 28:28.020 Over here. 28:28.020 --> 28:30.630 Let's not return when we update camera status. 28:30.630 --> 28:32.250 I think this what breaks. 28:33.200 --> 28:34.220 The deal. 28:34.220 --> 28:35.180 Going to save it? 28:35.180 --> 28:36.530 I'm going to try again. 28:39.610 --> 28:42.880 Let's go to Game View and let's go to play mode. 28:46.410 --> 28:46.830 All right. 28:46.830 --> 28:48.090 There is player one. 28:48.270 --> 28:50.160 Camera follows the player one. 28:50.580 --> 28:51.600 Very nice. 28:51.630 --> 28:53.280 Now let's make a second one. 28:53.280 --> 28:55.050 And there is a second player. 28:55.620 --> 28:56.250 Okay. 28:56.250 --> 28:57.150 Very good. 28:58.510 --> 29:00.520 Now let's try to walk here. 29:00.550 --> 29:01.990 Camera zooming out. 29:01.990 --> 29:04.540 I like it so we can see both of them. 29:05.120 --> 29:07.370 Now let me get the second layer there. 29:10.320 --> 29:12.420 I know Mushroom Hill. 29:13.970 --> 29:14.540 Now. 29:14.540 --> 29:16.100 First player goes here. 29:16.830 --> 29:17.400 Oh. 29:18.350 --> 29:20.210 It should be disabled by default. 29:20.540 --> 29:21.980 Now let me go there. 29:22.340 --> 29:23.720 Let me take level limits. 29:23.750 --> 29:25.160 Let me disable it. 29:27.880 --> 29:32.860 I just disabled the door from a second level because this one should be disabled by default. 29:32.890 --> 29:36.010 Okay, so I can go there, but I cannot go further. 29:36.010 --> 29:37.390 I can only return. 29:37.870 --> 29:39.040 This is good. 29:39.070 --> 29:41.650 Now let's try to walk there together. 29:42.520 --> 29:46.510 And yes, we did change the view to another level. 29:46.510 --> 29:47.800 This is all good. 29:47.800 --> 29:50.500 And also, if we want we can walk back. 29:50.500 --> 29:51.460 Let's go by the. 29:52.790 --> 29:54.500 And both of us here. 29:55.240 --> 29:56.050 Okay. 29:56.930 --> 29:57.560 Very nice. 29:57.560 --> 30:00.320 It works, I love it, I love the system. 30:00.320 --> 30:02.750 This looks so cool and feels so nice. 30:03.440 --> 30:04.460 Uh, let's. 30:05.680 --> 30:11.860 Go to level camera and in the wake I'm going to disable level limits. 30:12.940 --> 30:13.240 Wait. 30:13.240 --> 30:14.920 Enable limits. 30:15.760 --> 30:16.060 Polls. 30:16.060 --> 30:20.680 So we're going to disable limits in their wake, but then we're going to enable them when player is 30:20.680 --> 30:22.420 joining the game. 30:22.420 --> 30:22.930 Right. 30:32.540 --> 30:34.070 Okay, I think that's it. 30:34.100 --> 30:35.810 Now let's take these limits. 30:37.400 --> 30:39.440 Let's make them transparent. 30:40.580 --> 30:42.440 Just like that, so it's not visible. 30:42.440 --> 30:44.840 And let's go to the next video. 30:45.140 --> 30:45.830 Yay!
