1 00:00:00,000 --> 00:00:01,000 Hello, guys. 2 00:00:01,000 --> 00:00:02,000 Welcome back. 3 00:00:02,000 --> 00:00:07,000 And in this video I want to make the player will not run until you press some button because now he 4 00:00:07,000 --> 00:00:08,000 starts immediately. 5 00:00:08,000 --> 00:00:10,000 And this is not how it should work. 6 00:00:10,000 --> 00:00:14,000 I guess So let's go to script again now. 7 00:00:14,000 --> 00:00:15,000 You know how to use input. 8 00:00:15,000 --> 00:00:17,000 Now you know why he's running? 9 00:00:17,000 --> 00:00:21,000 Because we change his velocity in the update function every frame. 10 00:00:21,000 --> 00:00:21,000 Right? 11 00:00:21,000 --> 00:00:23,000 So that's how that works. 12 00:00:23,000 --> 00:00:24,000 I want to use boolean this time. 13 00:00:24,000 --> 00:00:26,000 It's time for you to learn about boolean. 14 00:00:26,000 --> 00:00:34,000 I'll just create public boolean and I'll name it as run begun, run, begun. 15 00:00:34,000 --> 00:00:36,000 Now let's go to update and type. 16 00:00:36,000 --> 00:00:46,000 If run began equals equals to true, then let's put this line of code inside and we can just cut it 17 00:00:46,000 --> 00:00:48,000 out like that and paste it in. 18 00:00:48,000 --> 00:00:54,000 Or we can hold my old key or your like just old key. 19 00:00:54,000 --> 00:00:55,000 Nobody is old key. 20 00:00:55,000 --> 00:01:00,000 Just hold out and press arrow down or up to move them. 21 00:01:01,000 --> 00:01:02,000 I would like that. 22 00:01:02,000 --> 00:01:06,000 Then I click home button, click tap to make it cleaner to delete this one and it looks better. 23 00:01:06,000 --> 00:01:10,000 Now I'm going to tell you some more about clean code practice. 24 00:01:10,000 --> 00:01:11,000 Just stay with me on this one. 25 00:01:11,000 --> 00:01:13,000 We go back to Unity, let it assemble. 26 00:01:13,000 --> 00:01:14,000 We can see run. 27 00:01:14,000 --> 00:01:16,000 Begun is false. 28 00:01:16,000 --> 00:01:20,000 I don't really like the name, but we'll have to stick with it for now. 29 00:01:20,000 --> 00:01:22,000 And if I hit play, he's not running. 30 00:01:22,000 --> 00:01:26,000 But if I make it true, he's running. 31 00:01:27,000 --> 00:01:30,000 And he stops and running. 32 00:01:30,000 --> 00:01:35,000 Now I need the way to make him run from the keyboard. 33 00:01:35,000 --> 00:01:39,000 So I don't use this checkbox in the inspector. 34 00:01:39,000 --> 00:01:43,000 I use my keyboard and that is a challenge for you. 35 00:01:43,000 --> 00:01:45,000 And that is easy challenge. 36 00:01:45,000 --> 00:01:48,000 You probably know how to do this. 37 00:01:48,000 --> 00:01:53,000 So you pause the video and I'll count till two and then I'm going to show you how to do that. 38 00:01:54,000 --> 00:01:55,000 One, two. 39 00:01:55,000 --> 00:02:04,000 Okay, so we go to update maybe somewhere here and type if input get button down. 40 00:02:04,000 --> 00:02:06,000 And now we need a name of a button. 41 00:02:06,000 --> 00:02:09,000 Let's go and see this what we can use but can unity. 42 00:02:09,000 --> 00:02:12,000 We go to edit project settings. 43 00:02:12,000 --> 00:02:13,000 Hmm. 44 00:02:14,000 --> 00:02:15,000 Fire. 45 00:02:17,000 --> 00:02:21,000 So fire one is a mouse zero and fire two is a mouse one. 46 00:02:21,000 --> 00:02:25,000 So let's use fire to like the right button of the mouse. 47 00:02:25,000 --> 00:02:25,000 Yeah. 48 00:02:27,000 --> 00:02:30,000 Fire to then run begun. 49 00:02:31,000 --> 00:02:32,000 Equals to true. 50 00:02:33,000 --> 00:02:34,000 Let's go back. 51 00:02:36,000 --> 00:02:37,000 Now we start the game. 52 00:02:37,000 --> 00:02:38,000 Nothing happens. 53 00:02:38,000 --> 00:02:43,000 And if I click my right button on the mouse, he is running. 54 00:02:45,000 --> 00:02:46,000 And we can jump. 55 00:02:47,000 --> 00:02:48,000 Cool. 56 00:02:48,000 --> 00:02:49,000 That works. 57 00:02:49,000 --> 00:02:51,000 And I think you understand what we did there. 58 00:02:51,000 --> 00:02:55,000 Now, let's talk a bit about cleaning this because this looks bad. 59 00:02:55,000 --> 00:02:56,000 I don't like it. 60 00:02:56,000 --> 00:03:01,000 First, there is a different way to check if bullying is true or false. 61 00:03:01,000 --> 00:03:04,000 We use this one just for you to understand. 62 00:03:04,000 --> 00:03:08,000 If we want to check if it's false, we could do equals to false. 63 00:03:08,000 --> 00:03:10,000 Or we could do. 64 00:03:12,000 --> 00:03:12,000 Sorry. 65 00:03:14,000 --> 00:03:22,000 Not equal to true, but there is a different way we can just type if run begun and that just making 66 00:03:22,000 --> 00:03:24,000 check if run began is true. 67 00:03:24,000 --> 00:03:26,000 If we want to make sure it's false, we do. 68 00:03:26,000 --> 00:03:27,000 If. 69 00:03:27,000 --> 00:03:30,000 Not run begun with exclamation mark. 70 00:03:30,000 --> 00:03:32,000 But we're going to have more of that practice later. 71 00:03:32,000 --> 00:03:33,000 Don't worry about it. 72 00:03:34,000 --> 00:03:39,000 Now, something else here is you can see I'm writing my if statement and then I'm making curly brackets. 73 00:03:39,000 --> 00:03:45,000 But if in the curly brackets only one line of code, we don't have to type curly brackets at all. 74 00:03:45,000 --> 00:03:51,000 We can just make it look like this and this still will work the same. 75 00:03:51,000 --> 00:03:56,000 It works only if you have one line of code after the if statement, but I kind of like it to see this 76 00:03:56,000 --> 00:03:56,000 way. 77 00:03:56,000 --> 00:04:03,000 It looks much better and something else to do here because we already have a couple of inputs and later 78 00:04:03,000 --> 00:04:05,000 on we're going to put more code in the update. 79 00:04:05,000 --> 00:04:06,000 We need to make it look clean. 80 00:04:06,000 --> 00:04:07,000 We need to arrange it. 81 00:04:07,000 --> 00:04:17,000 So let's select all of these code like that click alt plus enter and we click extract method. 82 00:04:17,000 --> 00:04:22,000 Then let's give it a name and I'll name it as check input, click enter. 83 00:04:22,000 --> 00:04:29,000 And now we have function that holds all of the input info inside and we just call this function in the 84 00:04:29,000 --> 00:04:30,000 update. 85 00:04:30,000 --> 00:04:31,000 So basically it works the same. 86 00:04:31,000 --> 00:04:38,000 If for some reason your alternator didn't work, then you can just create a function like private void 87 00:04:39,000 --> 00:04:45,000 check and check input and just copy this code inside. 88 00:04:46,000 --> 00:04:46,000 Think a bet? 89 00:04:47,000 --> 00:04:47,000 Yeah. 90 00:04:47,000 --> 00:04:48,000 All right. 91 00:04:49,000 --> 00:04:50,000 Good. 92 00:04:50,000 --> 00:04:50,000 We began. 93 00:04:50,000 --> 00:04:51,000 Very good. 94 00:04:51,000 --> 00:04:53,000 Let's go further. 95 00:04:53,000 --> 00:04:54,000 Let's go to next video.
