WEBVTT 00:00.020 --> 00:00.440 Hello guys. 00:00.440 --> 00:01.310 Welcome to the video. 00:01.310 --> 00:06.380 In this one we need to adapt skin selection for two players so you can choose skin for the first player 00:06.380 --> 00:08.990 and for the second one it's going to be not that difficult to do. 00:08.990 --> 00:10.340 Just takes a bit of a time. 00:10.340 --> 00:12.320 And I think we can start right now. 00:12.320 --> 00:14.540 So we need to go to the main menu scene. 00:15.920 --> 00:18.530 And then we need to find this kin selection. 00:18.530 --> 00:20.780 And I want to explain how it's going to work. 00:22.780 --> 00:27.400 So I need this menu character animator. 00:28.330 --> 00:29.230 Layers. 00:29.230 --> 00:30.970 And then we need skin selection. 00:31.030 --> 00:31.780 Okay. 00:32.860 --> 00:38.920 So look, as of now we have skin index number that cannot be bigger than max index. 00:38.920 --> 00:42.520 And then we switch it from minimum to maximum or an opposite. 00:42.520 --> 00:46.390 And then with this number we choose layer on the animator. 00:46.390 --> 00:50.020 And at the same time we send same number to the skin manager. 00:50.020 --> 00:56.230 This is what we do now instead of this I want to have a list of numbers so we can find an element, 00:56.230 --> 01:02.830 check which skin ID that element has and then choose skin from that because we cannot just leave it 01:02.830 --> 01:03.940 as it is right now. 01:03.940 --> 01:09.880 We need to be able to remove one of the skins from the list when it is already chosen by player, because 01:09.880 --> 01:13.240 we don't want players to have two same skins, right? 01:13.240 --> 01:14.620 Uh, this is how it's going to be. 01:14.650 --> 01:19.960 We're going to go to us skin selection, and I'm going to do a little bit of a change here. 01:20.260 --> 01:21.850 Uh, we're going to make a header. 01:25.030 --> 01:28.150 UI skin details, maybe like that. 01:28.150 --> 01:30.640 Then I want to take skin index. 01:30.640 --> 01:31.870 Move it here. 01:33.330 --> 01:37.710 And we're going to rename it to Current Skin Index. 01:38.160 --> 01:43.500 After that we're going to need serialized field list of integers. 01:43.800 --> 01:46.200 And we're going to name it as skin index. 01:46.200 --> 01:52.290 Then we don't need the max index anymore because we're going to use skin index dot count as a maximum 01:52.290 --> 01:52.920 value. 01:52.920 --> 01:55.410 So I'm going to remove it from here okay. 01:56.890 --> 01:57.880 Very nice. 01:57.880 --> 02:04.720 Now let's go down to the next skin and previous skin and change method slightly. 02:05.320 --> 02:07.240 Uh, we're going to go here. 02:08.870 --> 02:15.320 So instead of using max index, we're going to use, um skin index dot count. 02:15.320 --> 02:17.510 And we need to do minus one here. 02:18.020 --> 02:19.940 Then over here we need to do. 02:21.040 --> 02:21.970 In index. 02:22.690 --> 02:24.730 Dot count minus one. 02:25.150 --> 02:31.390 We do minus one because if we have four elements in the list, then last element would have number three, 02:31.390 --> 02:32.080 not four. 02:32.080 --> 02:36.520 And if we want to choose the last one which is supposed to be three, then we need to do minus one. 02:36.520 --> 02:37.060 All right. 02:37.060 --> 02:42.250 So this half of the job here then let's go to update skin display. 02:44.580 --> 02:51.270 And over here I want to make an integer int nu skin index, which will be equals to. 02:54.650 --> 03:00.050 Skin index with a current skin index just like that. 03:00.680 --> 03:05.270 Uh, maybe let's rename this to Selected skin index. 03:05.690 --> 03:07.100 Now over here. 03:07.100 --> 03:07.280 Oh. 03:07.280 --> 03:08.810 I'm sorry, what was that? 03:10.960 --> 03:12.220 What was that? 03:12.640 --> 03:19.630 Then over here, instead of current skin index that we used before, we need to use selected skin index. 03:19.630 --> 03:21.550 If it doesn't make sense, just wait a bit. 03:21.550 --> 03:24.430 I'm going to show it to you in unity and you'll understand it. 03:25.920 --> 03:27.630 So we're using it here. 03:27.630 --> 03:34.890 And also now we need to check if skin list with the selected skin index is unlocked. 03:36.310 --> 03:42.610 And then over here we need to choose selected skin index like that. 03:44.000 --> 03:44.870 Very good. 03:44.870 --> 03:46.970 Now let's save everything. 03:46.970 --> 03:48.740 Let's go back to unity. 03:50.690 --> 03:51.230 Over here. 03:51.230 --> 03:54.380 We can see we've got a list of indexes. 03:54.410 --> 04:03.050 Let's make size four and we have first, second, third and fourth element with the index of 01234. 04:03.050 --> 04:04.580 So this one's going to be zero. 04:04.580 --> 04:05.510 This one's going to be one. 04:05.510 --> 04:06.350 This one's going to be two. 04:06.380 --> 04:07.670 This one's going to be three. 04:07.670 --> 04:14.690 And this is how it is before we just took a number to choose a layer on the animator and skin in the 04:14.690 --> 04:15.590 skin manager. 04:15.590 --> 04:18.860 Now we're going to choose an element in the list. 04:18.860 --> 04:23.840 And then we're going to see which number this element has to make a final decision. 04:25.470 --> 04:27.990 Um, let's go to play mode. 04:29.690 --> 04:34.940 I'm going to show it to you so we can switch skins and we can see we switch in current skin index. 04:34.940 --> 04:40.400 And as I mentioned before, we took this number and used it directly over here. 04:40.400 --> 04:43.850 And also we passed this number directly to the skin manager. 04:43.850 --> 04:46.040 What we're doing now is something different. 04:46.040 --> 04:50.390 We take this number to choose element in the list over here. 04:50.390 --> 04:52.160 And we chose number three. 04:52.160 --> 04:55.940 And we can see that element three has skin index three. 04:55.940 --> 04:59.600 But let's say first layer chose um. 05:00.590 --> 05:01.400 Musk dude. 05:01.640 --> 05:07.610 And we want to remove musk dude from the selection now because this one was chosen by the first player. 05:07.610 --> 05:11.210 So we're gonna select the skin we're going to pass in photo skin manager. 05:11.210 --> 05:15.410 And after that we're going to remove this element from the list like that. 05:15.410 --> 05:22.430 Now zero element will have zero element one will have one and element two will have three. 05:22.430 --> 05:26.780 And now when you switch between them you can only switch between these three. 05:26.780 --> 05:32.540 And again this is why it's important to have a list because now current skin index will send us to element 05:32.540 --> 05:33.710 two in the list. 05:33.710 --> 05:36.890 And element two will have skin index of number three. 05:37.160 --> 05:37.970 And. 05:38.910 --> 05:39.360 Basically. 05:39.360 --> 05:39.750 That's it. 05:39.750 --> 05:40.770 That's what we're doing. 05:40.770 --> 05:44.070 Then we're taking this number and we're giving it to Skin Manager. 05:44.070 --> 05:47.760 And we also given this number to the animator layer. 05:47.880 --> 05:48.450 Okay. 05:48.990 --> 05:49.920 Very nice. 05:53.340 --> 05:55.950 Now let's go ahead and make functionality further. 05:56.340 --> 06:02.250 Uh, first of all, I would like to reset skin selection when we press back button. 06:04.490 --> 06:06.320 Uh, we need to go. 06:08.680 --> 06:12.010 Uh, maybe somewhere here we're going to make private void. 06:12.430 --> 06:14.890 Reset skin choices. 06:15.660 --> 06:19.440 Actually, this should be public because we're going to attach this method to the back button. 06:19.950 --> 06:22.320 Or we could just call it on enable. 06:22.320 --> 06:23.610 Yeah that's what we're going to do. 06:23.610 --> 06:24.960 Let's keep it private. 06:24.960 --> 06:30.690 So over here we want to take a list of skin index skin index list. 06:30.690 --> 06:34.500 And we're going to make it equals to new list of integers. 06:34.500 --> 06:39.450 In this way we're going to refresh the list every time we enable UI. 06:39.480 --> 06:41.400 After that we're going to make for loop. 06:43.120 --> 06:46.360 And as a length we're going to use skin list. 06:46.630 --> 06:48.220 Skin list dot length. 06:48.250 --> 06:53.680 So it means we're going to set up skin index list according to the amount of skins we have in the skin 06:53.680 --> 06:54.640 list array. 06:54.640 --> 06:56.980 And over here we're going to do skin index. 06:58.130 --> 06:59.930 AD and we just want to add an index. 06:59.930 --> 07:01.910 So we're going to add I over there. 07:01.910 --> 07:04.910 This one will reset the list and it will fill it up with numbers. 07:04.910 --> 07:09.260 Every time you enable UI we just need to go to UN enable. 07:10.710 --> 07:11.640 Over here. 07:11.640 --> 07:18.870 And we're going to do reset skin choices also, just in case we can do this in the week before we load 07:18.870 --> 07:23.790 skin unlocks, not to break the system, reset skin choices. 07:24.360 --> 07:25.110 Nice. 07:26.800 --> 07:27.610 This is good. 07:27.610 --> 07:33.340 Now we need to make a functionality that would help us to choose skins for the player for the first 07:33.340 --> 07:36.970 one, and for the second one we have this select skin method. 07:36.970 --> 07:39.220 And if we did not unlock the skin, we're going to buy it. 07:39.220 --> 07:43.420 But if we did unlock the skill we're going to select it just to make code cleaner. 07:43.420 --> 07:47.080 I'm going to take these two lines of code and I'm going to rub them into a method. 07:48.140 --> 07:49.310 Select. 07:49.640 --> 07:49.970 Um. 07:52.080 --> 07:53.970 Now we already have select skin. 07:55.260 --> 07:56.670 Let's do it like that. 07:58.430 --> 08:01.550 Let's rename this to Select Skin button. 08:02.350 --> 08:04.450 And this one going to be Select skin. 08:05.970 --> 08:06.690 All right. 08:06.690 --> 08:07.650 Very nice. 08:08.370 --> 08:11.610 Uh, now we're going to have to reassign this button, but it's fine. 08:11.610 --> 08:13.980 It's not that difficult to do over here. 08:13.980 --> 08:15.210 We need to check something. 08:15.210 --> 08:20.310 We need to check if this is the first player pressing the button or the second one. 08:20.310 --> 08:24.750 Basically, we want to check for which player currently we selecting the skin. 08:24.750 --> 08:30.570 If current player index is lower than maximum player count, then we still selecting the skin. 08:30.570 --> 08:32.580 We can just confirm it and save the info. 08:32.580 --> 08:38.490 But if we choosing the last skin for the last player, then we're going to switch UI. 08:38.580 --> 08:39.840 To do all of that. 08:39.840 --> 08:45.150 We need to keep track of player index that we currently have while we are in the UI. 08:45.150 --> 08:46.800 So this is how we're going to do that. 08:47.070 --> 08:49.470 We're going to go here and we're going to make public values. 08:49.470 --> 08:50.760 I just want you to see them. 08:50.760 --> 08:53.130 But later we're going to hide the values. 08:53.130 --> 08:54.360 You're going to do public. 08:56.000 --> 09:03.200 Int max player count and then public int current player index. 09:03.200 --> 09:06.800 Maybe let's be consistent and let's rename this to index. 09:07.280 --> 09:12.140 So max player index and current player index these two values that we're going to use. 09:12.500 --> 09:17.510 And let's go to reset skin choices and update these values just in case. 09:18.690 --> 09:26.280 So over here in the reset skin choices I'm going to do um, max player index is equals to player manager 09:26.760 --> 09:29.130 instance max player count. 09:29.130 --> 09:34.710 And then I'm going to do current skin index equals to zero. 09:35.560 --> 09:38.860 And I guess this one should be minus one, right? 09:38.860 --> 09:43.270 Because we do max player count on the player manager from one, not from zero. 09:43.270 --> 09:44.890 Okay, let's see how it's going to work. 09:44.890 --> 09:45.940 Should be fine. 09:47.630 --> 09:48.890 So now we have current. 09:48.890 --> 09:50.930 Sorry, this should be current player index. 09:50.930 --> 09:52.280 Current player index. 09:52.280 --> 09:59.210 So now we have uh information about current player index and maximum player index we can go to skin 09:59.210 --> 10:00.200 selection. 10:00.940 --> 10:01.810 Method. 10:02.610 --> 10:03.660 Inside of this method. 10:03.660 --> 10:06.810 First we want to get the selected skin index. 10:06.810 --> 10:08.970 I'm going to do it in a very simple way. 10:08.970 --> 10:15.930 In selected skin index equals to skin index with the current skin index. 10:15.930 --> 10:20.760 So now we have number from the list that we need to use to choose the skin. 10:20.760 --> 10:21.870 Then we're going to do. 10:21.870 --> 10:29.550 If current player index is less than max player index it means we still choosing skin not for the last 10:29.550 --> 10:32.340 player, but for the previous one for the first player. 10:32.340 --> 10:35.370 And if that's the case, we can just choose the skin. 10:36.360 --> 10:39.930 You're going to drag this line of code over here, you're going to pass. 10:40.600 --> 10:44.740 Selected skin ID, and as a player, we're going to just pass. 10:45.010 --> 10:47.980 Uh, current player index like that. 10:49.030 --> 10:52.180 And then we want to increase current layer index. 10:52.180 --> 10:57.730 And in this way, next time we press in this button we're going to choose skin for the next player. 10:57.730 --> 10:59.800 Then over here we're going to do else. 10:59.800 --> 11:07.720 And inside of this else statement we're just going to select the skin for last player that we have. 11:09.190 --> 11:14.920 Like that, and then we just want to switch UI to the next one like that. 11:15.850 --> 11:16.180 All right. 11:16.180 --> 11:17.050 This is all what we need. 11:17.050 --> 11:19.720 Let me just explain once more, just in case. 11:19.720 --> 11:21.700 So we have current layer index. 11:21.700 --> 11:25.900 And if this value is less than max player index it means we just need to choose the skin. 11:25.900 --> 11:29.020 And then we need to prepare skin selection for the next player. 11:29.020 --> 11:30.340 So we're choosing the skin. 11:30.340 --> 11:32.770 And we're saying that current layer index is plus plus. 11:32.770 --> 11:35.920 So go and pay attention to the next player. 11:35.920 --> 11:42.430 Then once this statement is not met means current layer index is equals or bigger than max player index, 11:42.430 --> 11:45.040 then it means we're working with the last layer we have. 11:45.040 --> 11:50.980 And in that case we just need to set skin ID on a skin manager and switch UI to level selection. 11:50.980 --> 11:52.150 Simple as that. 11:53.670 --> 11:54.630 Okay. 11:54.870 --> 12:00.090 Uh, now let's go ahead and let's set up methods and let's see if it all works. 12:00.090 --> 12:01.770 Because I could forget something. 12:06.710 --> 12:07.940 Uh, let's go to the scene. 12:07.940 --> 12:09.890 Let's open skin selection. 12:09.890 --> 12:11.540 This one is okay. 12:11.540 --> 12:17.300 We just need to take this select button, and we need to, uh, change method over here. 12:19.490 --> 12:21.470 To select skin button. 12:22.370 --> 12:24.290 And I think this should be good. 12:24.560 --> 12:30.800 We probably have to add another text so we know for which player we currently choose in a skin. 12:30.800 --> 12:32.540 I'm going to take the skin price. 12:32.540 --> 12:33.770 Duplicate it. 12:33.950 --> 12:35.270 Move it above. 12:36.750 --> 12:40.110 Let's do a player number. 12:41.290 --> 12:41.860 Next. 12:42.760 --> 12:44.650 Also, you could put text here. 12:47.880 --> 12:48.450 Okay. 12:48.450 --> 12:52.560 And inside we need just a player number. 12:53.010 --> 12:53.640 Text. 12:55.320 --> 12:57.210 Uh, we don't need I can I'm going to delete it. 12:57.210 --> 12:58.380 And the text itself. 12:58.380 --> 13:02.070 I'm going to do alignment in the center like that. 13:02.490 --> 13:05.130 That's just increase text box over here. 13:05.130 --> 13:06.630 And this should be good. 13:06.630 --> 13:08.160 Let's say this one says. 13:08.870 --> 13:09.890 First layer. 13:09.890 --> 13:10.670 Nice. 13:10.670 --> 13:15.500 Now let's go and update this text as well on the button just in case. 13:15.800 --> 13:18.080 Uh, we're going to need the reference to this text. 13:19.430 --> 13:27.740 All the way above, we're going to need this serialized field private Text, mesh Pro GUI, layer number 13:27.740 --> 13:28.610 text. 13:29.060 --> 13:31.640 And then we need to go to the. 13:33.550 --> 13:34.870 Update skin display. 13:35.050 --> 13:42.730 And over here I'm going to take the button up layer button number text dot text equals to. 13:43.090 --> 13:44.950 You're going to give it a player's number. 13:44.950 --> 13:47.440 And we start indexation from zero. 13:47.440 --> 13:50.920 And if that's the case then I'm going to do current player index plus one. 13:51.430 --> 13:53.800 So we don't start from zero we start from one. 13:53.800 --> 13:57.040 And then I'm going to do plus player. 13:57.640 --> 13:59.920 Just like that should be good. 14:00.100 --> 14:01.360 Let's go back. 14:04.740 --> 14:07.020 We need to find this text. 14:07.020 --> 14:09.600 We need to give text over here. 14:09.780 --> 14:16.650 And I'm going to start everything from main menu because I want to do two players selection. 14:18.040 --> 14:20.110 To player over here. 14:20.110 --> 14:20.800 Normal. 14:20.800 --> 14:25.030 Now we have skin selection UI first player is choosing the skin. 14:25.030 --> 14:26.140 You can switch. 14:26.530 --> 14:26.920 Sorry. 14:26.920 --> 14:28.240 You can switch left and right. 14:28.240 --> 14:29.170 Just like that. 14:29.170 --> 14:34.090 We can see we changing current skin index and max player index is one. 14:34.090 --> 14:36.970 Current player index is zero, so it should be fine. 14:36.970 --> 14:42.400 If you are a bit confused by these numbers, you can just start indexation from one and do max player 14:42.400 --> 14:46.150 index equals to max player count on a player manager. 14:46.150 --> 14:49.570 So let's say my first player chooses the ninja frog. 14:49.570 --> 14:51.550 I'm going to press enter. 14:51.670 --> 14:55.090 Now we can see we have message second player. 14:55.090 --> 14:59.170 And I can see this skin did not disappear. 15:00.230 --> 15:02.510 And also we did not remove index from the list. 15:02.510 --> 15:04.130 So that is my mistake. 15:04.340 --> 15:06.980 Uh, let's go and fix it now before we check anything else. 15:07.950 --> 15:10.110 We just need to go to Select skin. 15:10.890 --> 15:15.540 And over here, every time we select a skin we want to do um. 15:17.440 --> 15:20.380 Skin index dot. 15:20.380 --> 15:23.020 Remove current skin index. 15:25.820 --> 15:28.430 Yes, just like that. 15:28.430 --> 15:30.260 And maybe. 15:30.260 --> 15:31.640 Should we remove it here? 15:31.640 --> 15:35.810 I think it's not important because this is the last selection, so it doesn't really matter. 15:36.440 --> 15:37.970 Uh, let's go and try again. 15:40.350 --> 15:41.850 Let's go to unity. 15:45.220 --> 15:47.830 Play to players normal. 15:47.830 --> 15:50.890 So first player choosing the skin. 15:50.890 --> 15:54.850 Let's say first player choosing ninja frog going to press enter. 15:54.850 --> 15:57.850 We did update skin display. 15:58.210 --> 16:01.120 We did remove it from skin index list over here. 16:01.120 --> 16:03.010 So now we have zero two and three. 16:03.010 --> 16:06.130 Second player can switch between these three only. 16:06.130 --> 16:07.360 This is good. 16:07.750 --> 16:09.670 Uh index is updated over here. 16:09.670 --> 16:10.510 This is good. 16:10.510 --> 16:12.100 Text on the button is updated. 16:12.100 --> 16:13.000 This is good. 16:13.000 --> 16:16.240 Now let's take a look at the skin manager. 16:17.320 --> 16:17.770 Okay. 16:17.770 --> 16:20.980 Element zero chose skin index one, which is correct. 16:21.010 --> 16:23.920 Now let me choose Pinkman for the second layer. 16:23.950 --> 16:25.210 I'm going to press enter. 16:27.780 --> 16:33.150 We can see skin manager has index three under element one, so it's fine. 16:35.760 --> 16:39.960 Doesn't really matter what happened with the skin selection now, because it should be okay anyway. 16:39.960 --> 16:45.750 But before we go to level and test this, I'm going to click back button and I'm going to try to check 16:45.750 --> 16:51.930 things again because I want to be sure we resetting the skins if player like did the wrong choice and 16:51.930 --> 16:53.280 they want to choose again. 16:54.430 --> 16:54.970 Okay. 16:54.970 --> 16:59.410 And you can see it was not updated for the second player, right? 17:02.420 --> 17:09.950 I'm going to click back play to players normal and we have text second player, although other variables 17:09.950 --> 17:11.150 are fine. 17:11.420 --> 17:14.540 So what we need to do here is something very simple. 17:18.800 --> 17:20.450 We doing this? 17:20.450 --> 17:28.550 Reset skin choices on enable in which we reset the current layer index, but we do not update skin display. 17:28.550 --> 17:30.470 And that may be the issue. 17:31.190 --> 17:33.410 And let's do update skin display here. 17:34.000 --> 17:35.110 Just in case. 17:35.110 --> 17:37.900 I'm going to save everything and we're going to try again. 17:40.430 --> 17:41.750 Let's go to play mode. 17:43.520 --> 17:44.840 Play to players. 17:44.840 --> 17:45.860 Normal. 17:46.040 --> 17:47.780 Uh, first player chooses Ninja Frog. 17:47.810 --> 17:49.130 Second player chooses the mask. 17:49.130 --> 17:49.550 Dude. 17:49.580 --> 17:50.510 Now they like. 17:50.510 --> 17:52.430 Oh, wait, I want to do another one. 17:52.460 --> 17:53.570 They're going back. 17:53.570 --> 17:55.220 Play two players. 17:55.220 --> 17:56.120 Normal. 17:56.120 --> 17:56.600 It is. 17:56.600 --> 17:57.590 Reset it. 17:58.580 --> 18:04.430 And it's fine, although it is reset to the ninja frog I guess because we did not reset current skin 18:04.430 --> 18:04.880 index. 18:04.880 --> 18:08.210 So if you want to reset to zero, you can do that. 18:08.210 --> 18:11.720 But I think I'm going to just maybe keep it as it is. 18:11.720 --> 18:12.260 It's okay. 18:12.260 --> 18:13.430 It doesn't really matter. 18:15.370 --> 18:15.760 Yeah. 18:15.760 --> 18:18.820 So let's say first layer chooses the Pinkman. 18:19.270 --> 18:21.460 Second one chooses the ninja frog. 18:21.460 --> 18:23.530 We have this info on a screen manager. 18:23.530 --> 18:24.610 We're choosing the level. 18:24.610 --> 18:26.230 We're going to level itself. 18:26.230 --> 18:29.710 I'm going to press the enter and first player is a Pinkman. 18:29.980 --> 18:30.520 Yay. 18:30.550 --> 18:32.290 Now let me take the second one. 18:32.900 --> 18:33.920 Join. 18:35.310 --> 18:37.530 It's a ninja frog, just as we chose. 18:37.560 --> 18:45.900 Now let's say the first player dies and he responds and the second player dies and he cannot respond. 18:45.900 --> 18:46.620 It's okay. 18:47.520 --> 18:48.450 All right. 18:49.180 --> 18:50.260 So system works. 18:50.260 --> 18:51.730 Let's go to next level. 18:52.120 --> 18:55.660 We are on the next level and we are there. 18:55.660 --> 19:00.700 I had an extra player there, but it's okay, we just need to change it on the scene itself. 19:00.700 --> 19:01.570 It's fine. 19:02.980 --> 19:03.550 Hey, boy. 19:03.550 --> 19:04.120 Come here. 19:04.120 --> 19:05.440 Let's finish the game. 19:05.500 --> 19:06.010 Okay? 19:06.010 --> 19:11.830 I can see a couple of places for cleanup, but we're going to do that, um, in the next video. 19:12.520 --> 19:13.540 The skin selection. 19:13.540 --> 19:15.520 UI itself works great. 19:15.520 --> 19:22.750 Again, if you want to reset skin selection fully, you can go to Reset Skin Choices and you can do 19:22.780 --> 19:25.750 current skin index equals to zero. 19:25.750 --> 19:29.020 Then it will choose the first one that it has in the list. 19:29.140 --> 19:30.850 Okay, I think that's it. 19:30.850 --> 19:32.410 Thank you so much for paying attention. 19:32.410 --> 19:35.080 Let's go to the next video and I'll see you there.
