WEBVTT 00:00.000 --> 00:00.420 Hello guys. 00:00.420 --> 00:01.350 Welcome to the video. 00:01.350 --> 00:03.690 In this one I want to do something with the fruits. 00:03.690 --> 00:08.940 So later on in the game we're going to have two stats while we completing the level. 00:08.940 --> 00:14.220 One of them will be how many fruits are collected and how many fruits total are there. 00:14.220 --> 00:17.250 And that's what I want to do in this video. 00:17.250 --> 00:21.930 And later on, once we build the UI, we can just take the information that we make in this video and 00:21.930 --> 00:23.580 just display it in the UI. 00:23.610 --> 00:24.510 Simple as that. 00:24.510 --> 00:27.150 Also, it is very easy to make so. 00:28.550 --> 00:31.460 Let's go to game manager over here. 00:31.460 --> 00:36.710 First of all, I want to rename this boolean because it's too long I'm going to type. 00:36.710 --> 00:39.170 Fruits are random. 00:39.530 --> 00:40.520 It's a bit better. 00:40.910 --> 00:42.860 And we need public. 00:45.220 --> 00:45.790 End. 00:46.630 --> 00:50.680 Total fruits like total fruits amount. 00:51.160 --> 00:53.500 Now we need to know how many fruits are there. 00:53.500 --> 00:56.320 And of course we could manually assign the number. 00:56.320 --> 00:58.150 Let me do close all but this. 00:58.450 --> 01:01.870 But that is not the way programming is working, right? 01:01.870 --> 01:07.150 We don't need to do everything manually except if we change amount of fruits on the level, we may forget 01:07.150 --> 01:08.170 to update this value. 01:08.170 --> 01:11.860 So I want to update this value in the script. 01:11.860 --> 01:19.630 Every time we start the game, let's open start method and we can make a local variable of array. 01:19.810 --> 01:22.690 Or probably I did not tell you about array before. 01:23.500 --> 01:25.960 Okay, first let me explain. 01:26.860 --> 01:28.150 Let me make public. 01:29.100 --> 01:29.580 Route. 01:30.120 --> 01:31.050 Uh, variable. 01:31.050 --> 01:36.540 And we're going to put these two square brackets, which makes it an array, sort of like a list but 01:36.540 --> 01:37.170 an array. 01:37.170 --> 01:39.660 And let's do all fruits. 01:41.400 --> 01:44.820 Let's save the script and let's go back to unity. 01:49.360 --> 01:55.450 Now we've got a list over here and we can assign fruits we have just like that. 01:56.260 --> 02:00.100 Now we have an array of the fruits we have on the level. 02:00.310 --> 02:08.920 And at the start, we can go back here and say that total fruits equals to all fruits. 02:08.920 --> 02:12.160 Dot lengths and lengths is the length of the array. 02:12.760 --> 02:18.130 If array has three elements then this value will be equals to three. 02:20.030 --> 02:20.810 You can see that. 02:20.810 --> 02:21.440 Okay. 02:21.440 --> 02:22.430 Very cool. 02:23.380 --> 02:27.850 However, that's not all of it because I want to make it work automatically. 02:27.850 --> 02:34.420 We can select objects with a component of a fruit into the array in the script. 02:34.420 --> 02:34.810 This. 02:34.810 --> 02:35.530 What are we going to do? 02:35.530 --> 02:39.790 All fruits equals to find objects of type. 02:41.340 --> 02:41.940 Route. 02:43.780 --> 02:44.320 Oh. 02:44.650 --> 02:45.790 What's up? 02:46.750 --> 02:49.570 Or we need to type find objects with a s. 02:50.250 --> 02:52.230 And still it has an error. 02:53.490 --> 02:54.540 Okay. 02:54.540 --> 02:58.200 They changed it in a unity 2023. 02:58.380 --> 02:59.610 Okay I see. 02:59.640 --> 03:03.540 So if you have unity 2023 we're going to write it differently. 03:03.540 --> 03:06.600 If you have unity 2022, this is how you can do it. 03:07.630 --> 03:10.480 But since I'm using 2023, let's do it differently. 03:10.480 --> 03:17.230 I think we can type over here, find objects by type and in the parentheses we need to type. 03:17.560 --> 03:22.060 This is new for me a sort mode none. 03:22.570 --> 03:24.310 So we don't have to sort it out. 03:24.310 --> 03:26.020 Now we can go back to unity. 03:26.020 --> 03:27.940 And I'm going to show you how it's going to work. 03:28.510 --> 03:33.520 And basically this will find all of the objects that are having a component of a fruit. 03:33.520 --> 03:36.550 And it's going to put it into the array that I showed you before. 03:38.230 --> 03:39.760 Let me clean the array. 03:39.760 --> 03:41.530 I'm going to make it empty. 03:43.550 --> 03:46.130 And I'm going to add another fruit on the level. 03:47.730 --> 03:53.520 So now we have four, and I'm supposed to have an array filled with new fruits, all four of them. 03:53.520 --> 03:56.280 And this should say for let's go to play mode. 03:58.290 --> 04:01.560 And we've got an array and this says four. 04:01.590 --> 04:02.280 Okay. 04:02.280 --> 04:03.300 Very cool. 04:03.330 --> 04:08.760 Now again we don't have a reason to keep this variable over here because we just need to count fruits 04:08.760 --> 04:09.660 on the level. 04:09.660 --> 04:13.320 Because of that I can remove this variable over here. 04:13.320 --> 04:18.870 And I can make a local variable root array just like that. 04:18.870 --> 04:21.420 And also we can wrap this into a method. 04:21.420 --> 04:23.430 So I'm going to press control dot. 04:24.300 --> 04:25.920 Extract method. 04:28.030 --> 04:30.670 Collect fruits info. 04:31.270 --> 04:32.470 Maybe just like that. 04:33.250 --> 04:34.120 Very nice. 04:34.120 --> 04:40.990 So now later on, once we have UI, we can display total amount of fruits in the corner of the screen 04:41.170 --> 04:42.190 over here. 04:42.190 --> 04:45.640 And we can just update the value of fruits that we picked up before.
