WEBVTT 00:00.080 --> 00:00.500 Hello guys. 00:00.500 --> 00:01.520 Welcome to the video. 00:01.520 --> 00:05.030 In this one I want to show you how to set up difficulty for the game. 00:05.030 --> 00:09.650 You're going to have a very simple setup, but it's pretty fun to make and pretty fun to play I believe. 00:09.650 --> 00:14.270 So what we're going to do here, we're going to have easy, normal and hard mode. 00:14.360 --> 00:17.450 Easy mode will be is the same as we have the game now. 00:17.450 --> 00:22.160 On a normal mode, you're going to lose fruits every time you get in damage or every time you fall into 00:22.160 --> 00:22.700 a dead zone. 00:22.700 --> 00:25.550 And if you have zero fruits, we're going to restart the level. 00:25.550 --> 00:30.440 And on a hard mode, no matter how you got the damage, you're going to restart the level from the beginning. 00:30.440 --> 00:31.700 That's what I want to do. 00:31.820 --> 00:35.360 So how are we going to pass info to the game? 00:36.390 --> 00:41.790 So first let's set up the difficulty so we can set the difficulty and pass it to the main scene. 00:42.180 --> 00:45.000 And I think we have two options here. 00:45.000 --> 00:47.940 One of them is to create a difficulty manager. 00:47.940 --> 00:55.440 Another option is to just rename this skin manager to Settings Manager and have everything in one script. 00:55.440 --> 00:58.740 There is no right or wrong choice here, but I'm a bit limited. 00:58.770 --> 01:04.740 I want this course to be as understandable as it can be, and I know that sometimes people go in the 01:04.740 --> 01:08.280 end of the section and they download the project, and it may happen. 01:08.280 --> 01:13.530 It will be difficult for them to find that skin manager was renamed to Setting Manager. 01:13.530 --> 01:15.270 It can take some time to figure out. 01:15.270 --> 01:18.150 So I want to make a new game object for this. 01:18.150 --> 01:24.030 But for personal project most likely I will do everything like setting manager and I would save everything 01:24.030 --> 01:24.300 there. 01:24.300 --> 01:27.810 Maybe we can do that later on on a cleanup or on the Polish stage. 01:28.110 --> 01:30.450 Now, uh, let me do this. 01:30.450 --> 01:35.130 Let's go and make empty object difficulty manager. 01:36.870 --> 01:38.520 Then we're going to need a script. 01:41.130 --> 01:43.440 Difficulty manager. 01:48.160 --> 01:50.050 I'm going to drag it here. 01:50.560 --> 01:52.330 Let's go inside of the script. 01:57.090 --> 02:00.660 And at the top we're going to declare the enum public enum. 02:01.670 --> 02:04.310 Difficulty, uh, type. 02:06.200 --> 02:07.580 It's going to be easy. 02:08.190 --> 02:09.210 Normal. 02:09.910 --> 02:10.510 Hard. 02:11.220 --> 02:18.810 Then we're going to make it as public static difficulty manager instance, and we're going to need a 02:18.810 --> 02:21.450 wake from a screen manager over here. 02:21.450 --> 02:23.790 That's why I said we can do everything in one script. 02:27.300 --> 02:29.490 Because they pretty much have same functionality. 02:30.150 --> 02:31.350 Uh, yeah. 02:31.350 --> 02:32.010 What is it?

09:10.120 --> 09:10.870 Yes. 09:13.090 --> 09:15.190 And this all looks a bit confusing. 09:15.190 --> 09:17.290 So we can take this into a method. 09:18.700 --> 09:20.620 Extract method and do. 09:21.510 --> 09:24.900 Uh, update game difficulty. 09:25.260 --> 09:25.950 All right. 09:28.800 --> 09:30.540 Now you can see me on the screen. 09:31.230 --> 09:32.940 This all looks good to me. 09:33.480 --> 09:37.830 And maybe we can just drag this over here to make it prettier. 09:41.130 --> 09:44.010 Now we need to use difficulty and game manager as well. 09:44.010 --> 09:44.940 So. 09:46.950 --> 09:53.460 I think we can make some sort of damage method that will decide what is going to happen with the player 09:53.460 --> 09:55.020 when he's getting damage. 09:55.020 --> 09:56.850 Let me move this below update. 09:56.850 --> 09:57.420 Okay. 10:00.200 --> 10:01.100 Over here. 10:01.400 --> 10:03.260 So I'm going to make a. 10:03.860 --> 10:05.870 Private void damage. 10:05.870 --> 10:07.550 Maybe we're going to need to make it public. 10:07.550 --> 10:09.800 But let's see when we get in damage. 10:09.800 --> 10:14.240 If game difficulty is equal to normal, we're going to do something. 10:14.240 --> 10:16.040 Then we're going to return from a method. 10:16.430 --> 10:21.440 For example, we're going to deduct fruit from a fruit collected on a game manager. 10:21.440 --> 10:23.900 And I know that variable is public over here. 10:23.900 --> 10:24.860 Fruits collected. 10:24.860 --> 10:27.590 But I did it only so we can see it is working. 10:27.590 --> 10:32.870 Overall it's better to keep it private since we still testing and developing the game. 10:32.870 --> 10:34.160 I'm going to keep it public. 10:35.640 --> 10:40.890 But to get the value or deduct the value, I'm going to make a method because that's a good practice. 10:42.200 --> 10:43.220 To do so. 10:43.220 --> 10:49.040 So over here I'm going to make public void remove route. 10:49.960 --> 10:50.830 And this will do. 10:50.860 --> 10:59.890 Fruits collected minus minus in game UI update fruit UI fruits collected total fruits and I want to 10:59.890 --> 11:06.790 make a public int fruits collected and it's going to return me fruits collected. 11:07.120 --> 11:07.780 Okay. 11:07.780 --> 11:08.860 Very nice. 11:09.220 --> 11:12.280 Now let's go back to player with this method. 11:12.820 --> 11:15.280 Let's go back over here. 11:15.640 --> 11:23.080 And when we get in damage and if game mode is normal we're going to do a game manager remove fruit. 11:23.350 --> 11:26.260 And then we want to check if we have fruits at all. 11:26.290 --> 11:29.170 Because if we don't have fruits we need to restart the game. 11:29.170 --> 11:32.650 So I'm going to do if uh game manager. 11:33.380 --> 11:41.420 Fruits collected is less or equals to zero, then we suppose to restart level. 11:43.000 --> 11:43.810 All right. 11:44.430 --> 11:48.750 And then after all of this, we're going to return. 11:49.290 --> 11:54.930 And then over here we're going to make another if statement if game difficulty equals to. 11:55.890 --> 11:56.580 Hard. 11:57.520 --> 11:58.480 Then we can just. 11:59.760 --> 12:01.410 Restart level. 12:01.800 --> 12:02.640 Just like that. 12:02.640 --> 12:04.080 No need to remove roots. 12:04.110 --> 12:05.400 No need to do anything. 12:05.400 --> 12:06.750 Because this is the hard mode. 12:06.750 --> 12:07.980 You have to be careful. 12:07.980 --> 12:09.630 You cannot get any damage. 12:09.750 --> 12:12.510 Now, when can we call this damage method? 12:13.490 --> 12:18.530 I think we need to call it when we get a knock back, and also when we fallen into a dead zone. 12:19.130 --> 12:20.390 So. 12:21.980 --> 12:23.540 Uh, for the knockback. 12:23.540 --> 12:24.530 It's easy. 12:25.640 --> 12:27.650 Knockback method is here. 12:27.650 --> 12:32.060 So we can just call it here or we can go to damage trigger. 12:34.730 --> 12:36.110 And just call it here. 12:36.720 --> 12:38.820 Right, but we would need to make it public. 12:39.390 --> 12:42.510 But we would know where do we call damage methods? 12:42.510 --> 12:44.280 So I kind of like this idea. 12:45.210 --> 12:47.670 Let's go here and make it public. 12:47.850 --> 12:55.020 So now we have public void damage on a damage trigger over here we can not only call knockback. 12:56.150 --> 13:01.910 And also we can do player damage and we need to go to the. 13:04.080 --> 13:04.890 Uh. 13:04.890 --> 13:05.970 That's all. 13:06.630 --> 13:07.470 Over here. 13:09.870 --> 13:12.780 And coal layer damage. 13:14.000 --> 13:14.900 All righty. 13:15.560 --> 13:16.640 Very nice. 13:16.640 --> 13:23.360 Now we don't want to respawn player if game is hard, so maybe we can just do the check inside of a 13:23.360 --> 13:24.230 game manager. 13:24.230 --> 13:25.910 Yeah, now this is all good. 13:25.910 --> 13:28.700 It's supposed to work, but I don't want to check it now. 13:28.700 --> 13:31.970 I want to set up a level restart and check it all together. 13:31.970 --> 13:33.620 So let's go to Game Manager. 13:37.320 --> 13:38.280 Um. 13:43.360 --> 13:44.080 Over here. 13:44.080 --> 13:46.030 I'm going to make private void. 13:47.930 --> 13:52.610 Load current scene and it will do. 13:52.640 --> 13:53.780 Scene manager. 13:55.250 --> 13:55.880 Load. 13:55.880 --> 13:58.040 Scene of a level. 14:01.890 --> 14:03.870 Last current level index. 14:04.140 --> 14:06.780 And then I want to make a public method. 14:07.670 --> 14:18.800 Public void restart level in which we're going to do UI in game dot instance fade effect. 14:20.680 --> 14:21.280 What's up?

15:53.250 --> 15:54.120 Yes. 15:56.810 --> 15:58.250 This is how it's going to be. 15:58.460 --> 16:05.120 Now, all of this supposed to work, we only need to call restart level on the player inside of a damage 16:05.120 --> 16:05.780 method. 16:05.780 --> 16:07.460 So let's go there. 16:09.760 --> 16:11.410 I'm going to do game manager. 16:11.890 --> 16:13.570 Restart level. 16:13.660 --> 16:15.160 And over here. 16:15.760 --> 16:16.540 Game manager. 16:16.540 --> 16:18.280 Restart level. 16:19.070 --> 16:20.000 All righty. 16:20.790 --> 16:21.720 Going to save this. 16:21.720 --> 16:24.000 And finally, this is ready. 16:24.450 --> 16:31.380 Oh, by the way, how it is working right now, if we have one fruit and we get in damage, then we 16:31.380 --> 16:32.430 will restart the level. 16:32.430 --> 16:33.810 That's not what I want. 16:33.810 --> 16:35.430 So let's. 16:37.310 --> 16:38.750 Let's do it like so. 16:38.750 --> 16:40.430 Let's do else. 16:40.940 --> 16:42.110 Remove fruit. 16:42.470 --> 16:43.550 So if you have. 16:44.670 --> 16:46.230 Cero or less, we're going to restart. 16:46.230 --> 16:48.660 Otherwise we're just going to remove fruit and nothing else. 16:48.870 --> 16:49.950 It should be better. 16:50.650 --> 16:51.310 Yeah. 16:51.340 --> 16:53.140 Let's go to unity now. 16:56.500 --> 16:58.150 I'm going to select my difficulty manager. 16:58.150 --> 16:59.560 I'm going to choose normal. 16:59.560 --> 17:00.880 I'm going to go to play mode. 17:05.240 --> 17:07.190 So I have one fruit getting damage. 17:07.190 --> 17:09.410 I lost it getting damage again. 17:10.250 --> 17:12.440 And my character did not die. 17:12.440 --> 17:13.820 But we restart the scene. 17:13.850 --> 17:15.830 Okay, I'm going to see how we can fix it. 17:15.830 --> 17:17.840 Let me try to jump into a bit. 17:20.000 --> 17:21.230 Now there is no dead zone. 17:23.230 --> 17:24.280 That's on. 17:30.730 --> 17:33.160 I know I have to start over. 17:38.030 --> 17:39.560 Jumping into a pit. 17:40.770 --> 17:41.850 Restarting. 17:42.030 --> 17:43.470 Okay, this is good. 17:43.470 --> 17:49.170 The only fix is to kill the player when he's getting damage like that. 17:49.170 --> 17:52.410 I like it now let's fix that problem with the knockback. 17:52.410 --> 17:56.970 So when you get knocked without HP or fruits, you're going to die immediately. 18:00.410 --> 18:01.640 Let's go over here. 18:01.640 --> 18:06.290 I'm going to just call method die here like that and over here as well. 18:06.290 --> 18:06.680 Die. 18:07.250 --> 18:07.730 Yeah. 18:14.330 --> 18:18.230 And over here we call damage before knockback on a damage trigger. 18:18.500 --> 18:19.910 I guess this is important. 18:24.550 --> 18:26.050 Don't forget to do this. 18:29.680 --> 18:30.070 Now. 18:30.070 --> 18:31.090 It should be good. 18:31.150 --> 18:33.760 Let me try to start game in a hard mode. 18:35.250 --> 18:36.180 Hard mode. 18:39.650 --> 18:45.620 Now, even though I have a fruit, I'm going to get damage and died and have to start over. 18:49.260 --> 18:49.980 Okay. 18:50.160 --> 18:52.050 What if I do normal mode?

19:15.170 --> 19:21.080 Lastly, I think the fade is too long when you die because this is the platformer game and I believe 19:21.080 --> 19:23.240 player would want to start over faster. 19:23.240 --> 19:27.350 So let's just go to game Manager over here. 19:27.950 --> 19:29.060 And. 19:31.480 --> 19:33.970 When we restart the scene. 19:36.600 --> 19:37.380 Over here. 19:37.380 --> 19:42.960 I'm going to do just a 0.75 F, so it's going to be faster. 19:42.990 --> 19:43.830 Okay. 19:43.830 --> 19:46.770 Hey guys, I just realized I forgot to show you something. 19:46.770 --> 19:48.360 Something very nice. 19:48.720 --> 19:51.180 Uh, let's go to the main menu. 19:51.660 --> 19:58.350 And over here I want to display what the difficulty does, like sort of a text over here that would 19:58.350 --> 20:02.850 say, hey, easy mode does this, normal mode does this. 20:02.850 --> 20:05.370 So how is it going to work?
