1 00:00:03,050 --> 00:00:07,250 In this lecture, we're going to set up our new input system so that when we push left or right or up 2 00:00:07,250 --> 00:00:12,890 or down, we're printing to the screen the -1 to 1 on the x and y axis. 3 00:00:12,890 --> 00:00:15,920 For our controller input, I'm going to jump over to Package Manager. 4 00:00:15,920 --> 00:00:19,850 So making sure I'm on Unity Registry, I'm going to search for input system. 5 00:00:19,850 --> 00:00:22,220 If you don't have it installed already, then click install. 6 00:00:22,220 --> 00:00:24,050 That will give you this fancy warning click. 7 00:00:24,050 --> 00:00:29,330 Yes, we're okay with all that stuff and that will cause unity to reboot, restart itself and go through 8 00:00:29,330 --> 00:00:30,410 a setup process. 9 00:00:30,440 --> 00:00:37,580 Now with the input system set up first step, click on player, add component input player inputs. 10 00:00:37,580 --> 00:00:40,130 What we're looking for here, why have we got all this noise going on? 11 00:00:40,130 --> 00:00:42,050 It feels like there's a lot of words on my screen at the moment. 12 00:00:42,050 --> 00:00:43,580 Let me just shuffle things around a little bit. 13 00:00:43,580 --> 00:00:44,000 Okay. 14 00:00:44,000 --> 00:00:46,190 So the first thing we need to do here is create actions. 15 00:00:46,190 --> 00:00:46,790 Click on that. 16 00:00:46,790 --> 00:00:48,770 That will ask, where would you like to save it? 17 00:00:48,770 --> 00:00:50,510 I don't have a photo for this at the moment. 18 00:00:50,510 --> 00:00:54,590 So new folder, I'm going to put this into input system. 19 00:00:54,590 --> 00:00:55,100 I think so. 20 00:00:55,100 --> 00:00:57,500 Nifty place for that double click on the folder. 21 00:00:57,500 --> 00:00:58,550 Save. 22 00:00:58,610 --> 00:00:59,510 We'll get an error. 23 00:00:59,510 --> 00:01:00,110 That's okay. 24 00:01:00,110 --> 00:01:01,580 That'll go away shortly. 25 00:01:01,580 --> 00:01:03,770 Let's have a look and see if we can find where that end up. 26 00:01:03,770 --> 00:01:05,150 So we have our input system. 27 00:01:05,150 --> 00:01:05,510 There we go. 28 00:01:05,510 --> 00:01:06,560 We've got our tail. 29 00:01:06,560 --> 00:01:09,140 Vania, I didn't do a very good job of renaming it, did I? 30 00:01:09,140 --> 00:01:09,920 I just clicked enter. 31 00:01:09,920 --> 00:01:11,420 But Tony is okay. 32 00:01:11,450 --> 00:01:15,140 It could probably rename it input actions, but I'm just going to have the one here so it doesn't matter 33 00:01:15,140 --> 00:01:15,830 so much. 34 00:01:15,830 --> 00:01:17,000 Back over to the player now. 35 00:01:17,000 --> 00:01:21,590 We need to make sure we drag that over into the action so it knows what we are actually doing. 36 00:01:21,590 --> 00:01:24,320 I'm going to double click on that to open it up to see what's going on here. 37 00:01:24,320 --> 00:01:25,250 The action is already set up. 38 00:01:25,250 --> 00:01:26,750 Move, look and fire. 39 00:01:26,750 --> 00:01:29,450 We're going to be using move a bunch in the next couple of videos. 40 00:01:29,450 --> 00:01:33,170 And then after that, we'll also be wanting to to be able to use jump. 41 00:01:33,170 --> 00:01:34,430 We have a fire in here. 42 00:01:34,430 --> 00:01:38,360 I'm not going to use fire for jumping because it's well, you know, fire is fire and jump is jump. 43 00:01:38,360 --> 00:01:40,700 We might wish to do fire at some point later on. 44 00:01:40,700 --> 00:01:42,770 So let's set ourselves up a jump action. 45 00:01:42,770 --> 00:01:44,480 I'm going to click on the plus button here. 46 00:01:44,600 --> 00:01:48,710 I'm going to add in the word jump and you can see it's of action type button. 47 00:01:48,710 --> 00:01:49,400 That's what we want. 48 00:01:49,400 --> 00:01:52,190 We don't want to have a value for our move. 49 00:01:52,190 --> 00:01:56,300 Let's see here we have a value which is a vector two on the left, right up here, down here, which 50 00:01:56,300 --> 00:01:57,590 is X and Y. 51 00:01:57,590 --> 00:01:58,400 But here, jump. 52 00:01:58,400 --> 00:01:58,970 That's cool. 53 00:01:58,970 --> 00:01:59,720 It's a button. 54 00:01:59,720 --> 00:02:05,180 Let's change the binding to let's see here on the keyboard and mouse scheme, I'm going to click on 55 00:02:05,180 --> 00:02:06,740 the pull down selector thing here. 56 00:02:06,740 --> 00:02:09,770 So one thing that's really cool, you can click on the listen button. 57 00:02:09,770 --> 00:02:13,520 It's not literally listening for what you're saying spacebar. 58 00:02:13,520 --> 00:02:14,360 It's not quite like that. 59 00:02:14,360 --> 00:02:15,740 It's listening to the keyboard input. 60 00:02:15,740 --> 00:02:20,300 So if I tap on the keyboard, it will show me that I just push space and I have space as the option. 61 00:02:20,300 --> 00:02:21,500 So I'll add that there. 62 00:02:21,500 --> 00:02:27,860 It's also let's see if we go next to jump and add another one, add a binding by clicking the plus button, 63 00:02:27,860 --> 00:02:28,970 click on the binding. 64 00:02:28,970 --> 00:02:31,970 We will make this the gamepad set up. 65 00:02:31,970 --> 00:02:33,830 We'll click on our little select thing here. 66 00:02:33,830 --> 00:02:38,150 Listen, and I don't have my controller turned on, but if I did have it turned on, then it would also 67 00:02:38,150 --> 00:02:38,930 listen for that. 68 00:02:38,930 --> 00:02:42,140 But I'm going to find GamePad and then just find buttons south. 69 00:02:42,140 --> 00:02:44,930 That's the button down the bottom of the four buttons on our gamepad. 70 00:02:44,930 --> 00:02:49,670 So now we've set up jump, which we'll use later on in this section when we're setting up jump for the 71 00:02:49,670 --> 00:02:50,360 character. 72 00:02:50,390 --> 00:02:51,500 Okay, we can close that out. 73 00:02:51,500 --> 00:02:52,370 We don't need it anymore. 74 00:02:52,370 --> 00:02:53,690 Back over to Player. 75 00:02:53,690 --> 00:02:59,900 I need to also open input settings and create a settings asset and that should be good to go with all 76 00:02:59,900 --> 00:03:01,190 the settings as they are in there. 77 00:03:01,190 --> 00:03:05,510 Now we have this input system settings asset that can sit down there and do what it's going to do. 78 00:03:05,510 --> 00:03:11,240 And you'll see we're using send messages and here are all the messages that are available to us, very 79 00:03:11,240 --> 00:03:15,440 similar to the way we've used on Trigger Enter or we've used on collision. 80 00:03:15,440 --> 00:03:19,790 These are the same sorts of things you can see on move is in there already and because we've created 81 00:03:19,790 --> 00:03:22,220 Jump, it's sitting here as an on jump. 82 00:03:22,220 --> 00:03:27,620 Now just to illustrate this super, super clearly if I was to double click on my actually while I'm 83 00:03:27,620 --> 00:03:31,550 here, I'm just going to grab my input system and pop it into the input system folder. 84 00:03:31,550 --> 00:03:32,240 So there we go. 85 00:03:32,240 --> 00:03:33,560 That was the input system. 86 00:03:33,560 --> 00:03:34,760 Dot asset. 87 00:03:34,790 --> 00:03:35,810 No, yes, dot asset. 88 00:03:35,810 --> 00:03:36,680 It is great. 89 00:03:37,280 --> 00:03:42,200 I'm going to open up my input actions again and input actions in here. 90 00:03:42,200 --> 00:03:47,990 If I was to go and create a new action and I called this donkey, blah, blah, why donkey? 91 00:03:47,990 --> 00:03:51,620 Well, you tend not to have donkey anywhere in your programming, in your coding. 92 00:03:51,620 --> 00:03:54,620 So if you search for donkey, you'll be able to find this pretty easily. 93 00:03:55,160 --> 00:03:56,360 It's a Ben Tristram thing. 94 00:03:56,360 --> 00:04:00,530 Thank you, Ben, for giving me that habit of using Donkey as your word to search for. 95 00:04:00,560 --> 00:04:06,260 Now, when I click back on here in Behavior, you can see that we have on donkey blah blah that is now 96 00:04:06,260 --> 00:04:09,380 an option that if we had that bound to something in here. 97 00:04:09,380 --> 00:04:10,760 So currently it's not bound to anything. 98 00:04:10,760 --> 00:04:15,410 But if it were to bind that to something, then when that particular binding is executed, when a button 99 00:04:15,410 --> 00:04:21,320 is pushed or a keyboard key is pressed, then it will send the message that we want it to send over 100 00:04:21,320 --> 00:04:24,530 and here to send the on donkey blah blah message. 101 00:04:24,530 --> 00:04:27,110 And then we can set up whatever code we want within that. 102 00:04:27,110 --> 00:04:30,500 So I just wanted to illustrate for me, when I was first playing around with this, I was thinking, 103 00:04:30,500 --> 00:04:33,380 how do I, how do I access jump if there's no on jump? 104 00:04:33,380 --> 00:04:37,610 But it gets created for you when you create that new action, which is pretty nifty. 105 00:04:37,610 --> 00:04:43,490 Let me just very quickly get rid of Donkey Delete, right click delete just so it's not lingering around 106 00:04:43,490 --> 00:04:43,820 there. 107 00:04:43,940 --> 00:04:44,170 Okay. 108 00:04:44,210 --> 00:04:46,610 Now the other step is to create our script. 109 00:04:46,610 --> 00:04:51,200 So I'm going to click on assets, give ourselves a little bit more space here. 110 00:04:51,200 --> 00:04:52,520 It's getting running out of space, isn't it? 111 00:04:52,520 --> 00:04:53,720 These animated windows. 112 00:04:54,410 --> 00:04:55,670 We need a scripts folder. 113 00:04:55,670 --> 00:04:58,230 So right click, create a C-sharp script. 114 00:04:58,250 --> 00:04:59,750 Oh, I did that in the wrong order. 115 00:04:59,750 --> 00:05:00,920 Okay, well, fine. 116 00:05:00,920 --> 00:05:02,060 My brain's not quite working. 117 00:05:02,060 --> 00:05:02,540 We'll make this. 118 00:05:02,840 --> 00:05:06,220 Player movement script. 119 00:05:06,320 --> 00:05:06,850 Okay. 120 00:05:06,920 --> 00:05:09,560 And now we'll create the photo create folder. 121 00:05:09,590 --> 00:05:11,190 I was too hasty with my clicking, wasn't I? 122 00:05:11,210 --> 00:05:13,490 And I'll call this scripts. 123 00:05:15,010 --> 00:05:18,280 Scripts and drag my play and movement into scripts. 124 00:05:18,310 --> 00:05:20,680 It's a little bit of back to front with my order there. 125 00:05:21,010 --> 00:05:26,230 We'll find the player and I'm going to drag over the player movement script onto the player. 126 00:05:26,260 --> 00:05:32,380 While I'm here, I've been working in the instance, so I need to make sure I jump up to the prefab 127 00:05:32,380 --> 00:05:37,180 under overrides, apply all and then the player input and the player movement script will be applied 128 00:05:37,180 --> 00:05:37,990 to the prefab. 129 00:05:38,020 --> 00:05:40,000 Now let's open up our player movement script. 130 00:05:40,000 --> 00:05:43,450 We'll just do one or two very quick things here to get ourselves set up and ready. 131 00:05:43,450 --> 00:05:46,620 And then in the next lecture we'll actually be making him move. 132 00:05:46,630 --> 00:05:49,120 But for now, let's just remove our comments. 133 00:05:49,150 --> 00:05:55,000 And because we're using the new input system, we need to first of all access the namespace using unity 134 00:05:55,000 --> 00:05:59,440 engine dot input system semicolon. 135 00:05:59,440 --> 00:06:02,170 Now the cool thing we're trying to do here is within update. 136 00:06:02,170 --> 00:06:07,600 We want to say move the character, make the character run based upon what input the player is pressing 137 00:06:07,600 --> 00:06:09,640 and how do we know what the player is pressing? 138 00:06:09,640 --> 00:06:14,410 Well, as I pointed out before, we've got a message over in here, message, which is hopefully you 139 00:06:14,410 --> 00:06:14,830 can see that. 140 00:06:14,830 --> 00:06:17,110 Okay, on, move on. 141 00:06:17,110 --> 00:06:23,200 Move is going to be called when the player changes what they're what they're doing on the keyboard or 142 00:06:23,200 --> 00:06:25,150 keypad based upon our bindings. 143 00:06:25,150 --> 00:06:29,320 So if you're pushing left or pushing right or if you let go of pushing left or let go of pushing right. 144 00:06:29,320 --> 00:06:34,900 But because it's a message, it's saying the player push down left, there's a change, the player let 145 00:06:34,900 --> 00:06:35,950 go of the left arrow. 146 00:06:35,980 --> 00:06:36,550 That's a change. 147 00:06:36,550 --> 00:06:39,070 The player pushed right on the gamepad. 148 00:06:39,070 --> 00:06:46,120 So we need to grab that input at the moment that it happens and then store it into a variable that we 149 00:06:46,120 --> 00:06:52,270 can then use within update to say on every single frame, whatever is currently the setting or currently 150 00:06:52,270 --> 00:06:57,190 the input value, then continue to use that to update our player's action. 151 00:06:57,190 --> 00:06:57,440 Okay. 152 00:06:57,460 --> 00:06:59,230 So that's a bit of a wordy explanation. 153 00:06:59,230 --> 00:07:00,310 Hopefully it helps a little bit. 154 00:07:00,310 --> 00:07:03,640 I'm going to start with a vector too, because we need the X and the Y. 155 00:07:03,640 --> 00:07:08,110 We're looking at the character movement and I'm going to call this move input and this corresponds to 156 00:07:08,110 --> 00:07:10,480 whether you're pushing right or left up or down. 157 00:07:10,480 --> 00:07:12,130 We want to store it in to move input. 158 00:07:12,130 --> 00:07:13,840 How do we find what move input is? 159 00:07:13,840 --> 00:07:18,250 Well, we can put some information in our on move method. 160 00:07:18,250 --> 00:07:23,050 That's a message and is going to be getting cold when the player makes a change to to the key binding 161 00:07:23,050 --> 00:07:23,680 that we've got. 162 00:07:23,680 --> 00:07:26,950 And we need to get some information when that is called. 163 00:07:26,950 --> 00:07:29,770 And the information we need is an input value. 164 00:07:29,770 --> 00:07:32,140 We need a particular value and we'll just name this value. 165 00:07:32,140 --> 00:07:33,670 So the type is input value. 166 00:07:33,700 --> 00:07:39,040 We're giving it the name of value, and then we want to store our value that we're receiving from the 167 00:07:39,040 --> 00:07:45,550 input and store it in our vector too that we can use throughout our class in any of our different methods 168 00:07:45,790 --> 00:07:46,990 within update, etc.. 169 00:07:46,990 --> 00:07:53,650 So the way we're going to do that is very simply move input equals value, dot get. 170 00:07:53,650 --> 00:07:55,510 And then what do we need to get here? 171 00:07:55,510 --> 00:08:02,890 We need to get the vector to parentheses semicolon so there'll be a particular value and we want to 172 00:08:02,890 --> 00:08:05,830 assign that value to our move input variable. 173 00:08:06,040 --> 00:08:07,360 Now there's the last step in here. 174 00:08:07,360 --> 00:08:08,830 Let's check that this is working. 175 00:08:08,830 --> 00:08:11,650 I'm going to just do a debug log and what do you think? 176 00:08:11,650 --> 00:08:12,880 We're going to log out. 177 00:08:12,940 --> 00:08:17,470 We're going to log out, move input and save that up back over into unity. 178 00:08:17,470 --> 00:08:18,550 Let's see how that worked. 179 00:08:18,550 --> 00:08:19,960 We'll see if it did or didn't work. 180 00:08:19,960 --> 00:08:21,220 Clear some errors here. 181 00:08:21,250 --> 00:08:23,740 There's always going to be something that Rick has done wrong. 182 00:08:23,740 --> 00:08:25,240 Method must have a return type. 183 00:08:25,240 --> 00:08:26,080 Oh, Rick. 184 00:08:26,080 --> 00:08:27,460 Oh, Rick, what have you done here? 185 00:08:27,460 --> 00:08:29,020 We need to have void in front. 186 00:08:29,020 --> 00:08:29,740 My apologies. 187 00:08:29,740 --> 00:08:34,059 If you were yelling at the screen while I was doing that a little bit rusty today, not paying attention. 188 00:08:34,059 --> 00:08:35,710 That should clear things up. 189 00:08:35,740 --> 00:08:39,580 Okay, we'll click on play back into our game and let's see if that's going to work. 190 00:08:39,580 --> 00:08:41,049 Left Arrow Yeah, right. 191 00:08:41,049 --> 00:08:41,740 Arrow Cool. 192 00:08:41,740 --> 00:08:46,090 So it's showing that there's some change when we lift up or push down, lift up, push down. 193 00:08:46,090 --> 00:08:50,560 As we've done in previous lectures, we now have our input for up, down and left, right, and in the 194 00:08:50,560 --> 00:08:53,470 next lecture we can get our character running left and right. 195 00:08:53,470 --> 00:08:53,980 So good stuff. 196 00:08:53,980 --> 00:08:54,940 I'll see you in the next lecture.
