1 00:00:00,000 --> 00:00:00,000 Hello, guys. 2 00:00:00,000 --> 00:00:02,000 This video are going to be very short. 3 00:00:02,000 --> 00:00:06,000 I'm going to show you how to make simple input for your mobile phone. 4 00:00:06,000 --> 00:00:08,000 It's going to be simple touch input. 5 00:00:08,000 --> 00:00:12,000 So what we need to do first is go to player and make these two functions public. 6 00:00:12,000 --> 00:00:16,000 Slide button should be public and jump button should be public. 7 00:00:18,000 --> 00:00:20,000 Now let's save it and go back to Unity. 8 00:00:20,000 --> 00:00:21,000 What are you going to do next? 9 00:00:21,000 --> 00:00:25,000 Is go to in-game UI, click UI button, text. 10 00:00:25,000 --> 00:00:27,000 MASH Pro is going to be jump. 11 00:00:31,000 --> 00:00:32,000 Jump button. 12 00:00:34,000 --> 00:00:35,000 We need to make it bigger. 13 00:00:35,000 --> 00:00:36,000 Much bigger. 14 00:00:36,000 --> 00:00:37,000 Like half of the screen. 15 00:00:39,000 --> 00:00:41,000 And we can align it to the right. 16 00:00:41,000 --> 00:00:48,000 So let's click over here, hold alt and shift, click the right side and then maybe put it a bit lower. 17 00:00:50,000 --> 00:00:51,000 And let's duplicate this. 18 00:00:53,000 --> 00:00:53,000 Name it. 19 00:00:53,000 --> 00:00:54,000 Slide. 20 00:00:56,000 --> 00:00:58,000 Button and align it to the left. 21 00:00:59,000 --> 00:01:00,000 A bit lower. 22 00:01:00,000 --> 00:01:01,000 All right. 23 00:01:01,000 --> 00:01:04,000 Now we can select them both and make them transparent. 24 00:01:04,000 --> 00:01:08,000 And when you make a final build, it should be completely transparent like this. 25 00:01:08,000 --> 00:01:12,000 But for now, as we are testing, I'm going to make it slightly visible. 26 00:01:12,000 --> 00:01:13,000 I want to make sure it's working. 27 00:01:13,000 --> 00:01:16,000 Now let's open them and delete text from the inside. 28 00:01:17,000 --> 00:01:18,000 These two we don't need. 29 00:01:20,000 --> 00:01:26,000 Now, next step would be to create a C-sharp script UI jump button. 30 00:01:28,000 --> 00:01:32,000 But let's make it UI button jump. 31 00:01:39,000 --> 00:01:45,000 First, what we need is to go above and type using you to engine event system. 32 00:01:46,000 --> 00:01:49,000 And next, what we're going to use is an interface. 33 00:01:51,000 --> 00:01:54,000 It's a bit difficult to understand, especially if you're a beginner. 34 00:01:55,000 --> 00:01:58,000 But in general, I'll try to explain what the interface does. 35 00:01:58,000 --> 00:02:04,000 So basically interface allows you to have one function with a different functionality on different game 36 00:02:04,000 --> 00:02:08,000 objects that are independent from each other. 37 00:02:08,000 --> 00:02:16,000 For example, we can use a pointer down handler which allows you to call function when a pointer and 38 00:02:16,000 --> 00:02:21,000 pointer is an input device, for example mouse or touch from your finger. 39 00:02:21,000 --> 00:02:28,000 So when pointer on this game object with this interface function will be called let's click alt, enter 40 00:02:28,000 --> 00:02:31,000 and find implement interface the first one. 41 00:02:33,000 --> 00:02:35,000 And this was the function I was talking about. 42 00:02:35,000 --> 00:02:39,000 So we can call this interface from here or from another object. 43 00:02:39,000 --> 00:02:42,000 It's going to be same function with different functionalities. 44 00:02:44,000 --> 00:02:51,000 So for the button jump, we're going to do game manager instance player John Button. 45 00:02:52,000 --> 00:02:54,000 Now let's go back to Unity and create another script. 46 00:02:55,000 --> 00:02:57,000 C-sharp UI. 47 00:02:59,000 --> 00:03:03,000 But on slide and I'm using name button, slide and button jump. 48 00:03:03,000 --> 00:03:06,000 So they are next to each other in the asset folder. 49 00:03:06,000 --> 00:03:12,000 Otherwise, with the names like John Button and Slide button, slide button would be here and John Button 50 00:03:12,000 --> 00:03:15,000 would be at the top because of the alphabetic order. 51 00:03:15,000 --> 00:03:16,000 Yeah. 52 00:03:16,000 --> 00:03:19,000 So let's go to what was that button slide. 53 00:03:19,000 --> 00:03:21,000 We're going to delete, start an update. 54 00:03:21,000 --> 00:03:24,000 You're going to type here using Unity Engine. 55 00:03:27,000 --> 00:03:28,000 U.N. systems. 56 00:03:28,000 --> 00:03:30,000 And then over here, comma. 57 00:03:31,000 --> 00:03:32,000 Boynton down. 58 00:03:32,000 --> 00:03:35,000 We need to find a pointer down. 59 00:03:35,000 --> 00:03:37,000 Click all to enter implement interface. 60 00:03:39,000 --> 00:03:42,000 And here it's going to be the manager, for instance. 61 00:03:44,000 --> 00:03:45,000 Player. 62 00:03:45,000 --> 00:03:46,000 Slide button. 63 00:03:47,000 --> 00:03:49,000 And we actually can do this. 64 00:03:53,000 --> 00:03:55,000 And then click this icon over here to clean it up. 65 00:03:56,000 --> 00:03:57,000 That's the same for button jump. 66 00:04:01,000 --> 00:04:04,000 By the way, there is no difference to do it this way or that way. 67 00:04:04,000 --> 00:04:07,000 I mean, curly brackets or this one, just this one looks. 68 00:04:07,000 --> 00:04:08,000 I like how it looks. 69 00:04:08,000 --> 00:04:08,000 That's it. 70 00:04:10,000 --> 00:04:16,000 We have these two functions now, as I said, on pointer down will be called when pointer down on the 71 00:04:16,000 --> 00:04:19,000 object with this script. 72 00:04:19,000 --> 00:04:26,000 So we need to find our jump button, drag it here, then we need to find slide button, drag it here. 73 00:04:27,000 --> 00:04:28,000 Let's go and see this. 74 00:04:28,000 --> 00:04:32,000 Now tap to start to buttons appeared and jump is working. 75 00:04:34,000 --> 00:04:37,000 So when Jump is working and Slide is working. 76 00:04:37,000 --> 00:04:38,000 Now let's do a bit of polish on this. 77 00:04:38,000 --> 00:04:42,000 Let's take our info bar and find extra live display. 78 00:04:44,000 --> 00:04:47,000 I want to duplicate this and move it to the left like this. 79 00:04:49,000 --> 00:04:50,000 I want to delete one. 80 00:04:50,000 --> 00:04:54,000 And instead of heart over here, I want to place spread of the slide. 81 00:04:54,000 --> 00:04:56,000 Let's go to graphics player. 82 00:04:57,000 --> 00:04:58,000 Slide. 83 00:04:58,000 --> 00:05:00,000 You can take one of the sprites. 84 00:05:01,000 --> 00:05:03,000 Place it here and we need to rename the object. 85 00:05:04,000 --> 00:05:05,000 Slide icon. 86 00:05:05,000 --> 00:05:06,000 We can make it bigger. 87 00:05:06,000 --> 00:05:12,000 Let's press t and if you hold shift, you can increase the size without messing up the resolution. 88 00:05:12,000 --> 00:05:15,000 So maybe something like this is okay. 89 00:05:20,000 --> 00:05:26,000 And this is, I guess, just approximate size, something that you think looks okay. 90 00:05:26,000 --> 00:05:27,000 Don't sweat it out too much. 91 00:05:27,000 --> 00:05:31,000 Now, let's change this one to slide display. 92 00:05:33,000 --> 00:05:37,000 And I want to open my in-game UI here. 93 00:05:37,000 --> 00:05:40,000 I want to add new image that's going to be slide icon. 94 00:05:40,000 --> 00:05:42,000 So slide icon. 95 00:05:42,000 --> 00:05:48,000 Then let's go to our player script over here and we're going to make this slide call down counter public. 96 00:05:48,000 --> 00:05:51,000 Let's go above, find it, make it public. 97 00:05:51,000 --> 00:05:53,000 But I want to hide it in the inspector. 98 00:05:53,000 --> 00:05:54,000 So public. 99 00:05:55,000 --> 00:05:57,000 Hide, Inspector. 100 00:05:58,000 --> 00:05:59,000 Yeah. 101 00:05:59,000 --> 00:06:06,000 And back in the game UI in the update info function we're going to do slide icon enabled equals to layer. 102 00:06:06,000 --> 00:06:10,000 What was that slide cool down counter less than zero. 103 00:06:10,000 --> 00:06:15,000 If you remember, we use very same statement when we try to do slide it to make sure it's available 104 00:06:16,000 --> 00:06:18,000 right here in the slide button. 105 00:06:21,000 --> 00:06:24,000 And we have here a slide button slide called down counter less than zero. 106 00:06:24,000 --> 00:06:31,000 So basically we making this icon enabled if we can do a slide and now back in unity, we need to assign 107 00:06:31,000 --> 00:06:32,000 the image. 108 00:06:34,000 --> 00:06:39,000 Let's drag it here and now, whenever you try to do slide, if it's not available, picture is not going 109 00:06:39,000 --> 00:06:40,000 to be there. 110 00:06:43,000 --> 00:06:44,000 Slide. 111 00:06:45,000 --> 00:06:46,000 Okay, good. 112 00:06:46,000 --> 00:06:47,000 Let's go to the next video.
