1 00:00:04,310 --> 00:00:05,000 ‫Hello and welcome. 2 00:00:05,010 --> 00:00:10,220 ‫In this lecture, we're going to be looking at hooking up our character movement so that we can move 3 00:00:10,220 --> 00:00:13,310 ‫forward strife and look around our world. 4 00:00:13,310 --> 00:00:17,960 ‫The classics of moving around in a first person or third person shooter. 5 00:00:17,960 --> 00:00:19,400 ‫Let's dive in and see how it's done. 6 00:00:20,390 --> 00:00:26,420 ‫So continuing along in the vein of trying to get our character movement working, we are first of all 7 00:00:26,420 --> 00:00:32,000 ‫going to want to bind some input, but we're also going to know want to know what to bind that input 8 00:00:32,000 --> 00:00:32,750 ‫to. 9 00:00:32,930 --> 00:00:38,060 ‫Fortunately, when it comes to characters, there's a lot of simplifying stuff going on for us. 10 00:00:38,060 --> 00:00:43,760 ‫After all, Unreal really is an engine that's optimized for making things like shooter games, character 11 00:00:43,760 --> 00:00:44,390 ‫games. 12 00:00:44,390 --> 00:00:52,100 ‫And let's have a look at some of the movement functions that are already provided for us by the character 13 00:00:52,100 --> 00:00:57,650 ‫actor class, not just the character movement component, but also the character actor class provides 14 00:00:57,650 --> 00:01:02,480 ‫these and often passes a lot of this on to the character movement component, but not necessarily so. 15 00:01:02,480 --> 00:01:04,940 ‫Let's see what movement functions we're going to be dealing with. 16 00:01:04,940 --> 00:01:08,480 ‫First of all, there is going to be add movement input. 17 00:01:08,510 --> 00:01:12,830 ‫Add movement input basically takes a vector and tells you which direction you're going to move in. 18 00:01:12,830 --> 00:01:14,660 ‫So if it's a forward vector, you move forward. 19 00:01:14,660 --> 00:01:16,250 ‫If it's a backwards vector, you move backwards. 20 00:01:16,250 --> 00:01:18,650 ‫If it's a right vector, you move right and so on. 21 00:01:18,650 --> 00:01:22,580 ‫And the size of the vector is going to determine how fast you move in that direction. 22 00:01:23,000 --> 00:01:27,500 ‫The next thing is we've got add controller pitch input. 23 00:01:27,500 --> 00:01:32,090 ‫So that's about looking up and down, which is obviously very useful. 24 00:01:32,090 --> 00:01:35,540 ‫When you've got your mouse, you want to be looking up and down by moving your mouse up and down. 25 00:01:35,960 --> 00:01:39,980 ‫Then there's add controller, your input which is going left and right. 26 00:01:40,400 --> 00:01:45,080 ‫And finally there is a jump function which is just that maybe you hit the spacebar and you jump. 27 00:01:45,320 --> 00:01:52,220 ‫So with these things in mind, what we want to go ahead and do is create some bindings in our character 28 00:01:52,220 --> 00:01:55,850 ‫actor class that bind some input. 29 00:01:55,860 --> 00:02:01,700 ‫So some inputs from your keyboard, your mouse, your controller to these functions. 30 00:02:01,700 --> 00:02:05,510 ‫So we're going to do a few and then we're going to do a challenge to do the rest. 31 00:02:05,810 --> 00:02:11,120 ‫So let's go over to Visual Studio code and I'm in my shooter character. 32 00:02:11,450 --> 00:02:18,560 ‫H and we notice that we've got already here the set up player input component function. 33 00:02:18,560 --> 00:02:20,900 ‫This is where we need to bind our input. 34 00:02:21,020 --> 00:02:24,560 ‫Going to hit F12 to go over to the C++. 35 00:02:25,750 --> 00:02:31,900 ‫I'm going to hit Alt oh to go over to the C++ and find where we've got that set up. 36 00:02:31,900 --> 00:02:36,570 ‫So the first thing is it gives us this input component that we want to bind with. 37 00:02:36,580 --> 00:02:38,410 ‫If you remember, this is the way we do it. 38 00:02:38,410 --> 00:02:45,490 ‫We have a player input component, we use the arrow operator and we then do a bind function here. 39 00:02:45,490 --> 00:02:53,650 ‫So it's either a bind access or it's going to be a bind action depending on whether it's a discrete 40 00:02:53,650 --> 00:03:01,300 ‫action such as jump or whether it is an action that has a value such as looking up and down or moving. 41 00:03:01,660 --> 00:03:08,860 ‫Now, even when we do movement with a key, we still tend to bind it using an axis. 42 00:03:08,860 --> 00:03:14,230 ‫So I'm actually going to be making a bit of a typo for the first part of this video. 43 00:03:14,230 --> 00:03:19,990 ‫I will correct it later on, but do go ahead and use the bind axis instead of bind action here. 44 00:03:20,840 --> 00:03:29,000 ‫So really to take a step even further back, we need to go ahead and set up these actions and axes in 45 00:03:29,000 --> 00:03:29,950 ‫our project settings. 46 00:03:29,960 --> 00:03:32,120 ‫So let's go back over into Unreal. 47 00:03:32,150 --> 00:03:38,150 ‫Go to settings, project settings, and then I'm going to dock this down so we can see it very clearly 48 00:03:38,240 --> 00:03:42,020 ‫and we're going to go to the input section. 49 00:03:42,020 --> 00:03:48,770 ‫So engine input and set up some axes mappings and some action mappings. 50 00:03:50,590 --> 00:03:56,800 ‫So the ones I'm going to deal with right off the bat are the axes mappings for we're going to have, 51 00:03:56,800 --> 00:03:59,290 ‫first of all, a move forward. 52 00:04:00,230 --> 00:04:04,490 ‫And we're going to have also a look up. 53 00:04:04,520 --> 00:04:10,370 ‫Now, remember, we don't have a move forward and a move backwards because we can just do that with 54 00:04:10,370 --> 00:04:11,630 ‫negative scale. 55 00:04:11,780 --> 00:04:17,060 ‫So, for example, I want to set up my W Quay to be my move forward. 56 00:04:17,060 --> 00:04:18,650 ‫So that is scale one. 57 00:04:18,650 --> 00:04:25,250 ‫But if I want my se key to be my move back, I can still use move forward, but give it the scale of 58 00:04:25,250 --> 00:04:25,940 ‫minus one. 59 00:04:25,940 --> 00:04:27,240 ‫Just a quick reminder for you. 60 00:04:27,260 --> 00:04:28,430 ‫Same with look up. 61 00:04:28,430 --> 00:04:30,020 ‫I'm going to be using the mouse for this. 62 00:04:30,020 --> 00:04:33,110 ‫We'll cover controller input in the next lecture. 63 00:04:33,200 --> 00:04:35,620 ‫We're going to use the mouse y. 64 00:04:35,630 --> 00:04:41,030 ‫Now, remember, y is the one that goes up and down rather than left and right because it's kind of 65 00:04:41,030 --> 00:04:42,080 ‫a bit taller, isn't it? 66 00:04:42,080 --> 00:04:44,570 ‫A Y is a little bit of a taller letter than an X. 67 00:04:44,570 --> 00:04:45,950 ‫That's how I remember it anyway. 68 00:04:45,950 --> 00:04:52,130 ‫So Mouse Y is up and down and then we'll have to tweak with the scale, see whether it's going in the 69 00:04:52,130 --> 00:04:53,090 ‫right direction. 70 00:04:53,090 --> 00:04:57,620 ‫But basically this will give us negative values if we're going down and positive values if we're going 71 00:04:57,620 --> 00:04:58,070 ‫up. 72 00:04:58,070 --> 00:05:02,900 ‫So we may need to tweak with look up to see whether this is going to go in the right direction. 73 00:05:02,900 --> 00:05:09,230 ‫But you get the idea we can either invert the scale or not, depending on the type of input that's coming 74 00:05:09,230 --> 00:05:09,800 ‫in here. 75 00:05:10,950 --> 00:05:14,390 ‫So once we got the axis name, we can go back into the C++. 76 00:05:14,400 --> 00:05:19,590 ‫We're going to bind it using the text macro and the text of the axis name. 77 00:05:19,710 --> 00:05:25,180 ‫Then we need to say who we're going to call the function on and what function we're going to call. 78 00:05:25,200 --> 00:05:31,290 ‫We currently don't have a function that we want to call, so I'm going to go and create a new private 79 00:05:31,290 --> 00:05:35,160 ‫function over in my C++ header file. 80 00:05:35,280 --> 00:05:41,220 ‫And it is going to be a void function that is going to be called move forward. 81 00:05:42,320 --> 00:05:46,130 ‫And it's going to take the float, which is going to be the axis value. 82 00:05:49,380 --> 00:05:50,880 ‫Finish off with a semi-colon. 83 00:05:50,880 --> 00:05:55,320 ‫And I've got a little trick, a little extension here that helps me implement these things a little 84 00:05:55,320 --> 00:05:58,380 ‫bit quicker by doing control shift p and. 85 00:06:00,460 --> 00:06:06,640 ‫If I type in create implementation, it goes ahead and creates that implementation for me in the C++ 86 00:06:06,640 --> 00:06:06,940 ‫file. 87 00:06:06,940 --> 00:06:08,060 ‫Really nice and easy. 88 00:06:08,080 --> 00:06:09,460 ‫The name of that extension. 89 00:06:09,460 --> 00:06:14,470 ‫If I go over, I always forget the names of my extensions, so I'll go and have a look for what it might 90 00:06:14,470 --> 00:06:14,980 ‫be. 91 00:06:15,820 --> 00:06:18,310 ‫Yes, it's this little doozy here, the C++ helper. 92 00:06:18,310 --> 00:06:24,160 ‫If you go ahead and install this one for your VTS code, it just allows you to do that sort of thing, 93 00:06:24,160 --> 00:06:25,090 ‫which is very nice. 94 00:06:25,090 --> 00:06:25,810 ‫Very handy. 95 00:06:27,490 --> 00:06:30,060 ‫So this is the function that we want to set it up to call. 96 00:06:30,070 --> 00:06:32,850 ‫So first of all, we say this, this is the target. 97 00:06:32,860 --> 00:06:36,390 ‫The current object is the target for this function. 98 00:06:36,400 --> 00:06:42,850 ‫Then we go ahead and put in the issue to the fully qualified function issue, to character, colon, 99 00:06:42,850 --> 00:06:46,990 ‫colon move forward and that should bind us to this function. 100 00:06:47,530 --> 00:06:54,460 ‫And then finally, what we want to do is pass that axis value on to the function that we actually want 101 00:06:54,460 --> 00:06:57,430 ‫to call, which is a parent function. 102 00:06:57,430 --> 00:06:58,600 ‫So we don't have to do anything. 103 00:06:58,600 --> 00:07:01,660 ‫We can just do ad movement. 104 00:07:12,480 --> 00:07:13,680 ‫Input like so. 105 00:07:14,320 --> 00:07:20,640 ‫So because this is the move forward method, we want to have the forward vector of the actor. 106 00:07:20,650 --> 00:07:28,990 ‫So the way we do that is we can do a get actor forward vector like so and then we want it to be forward 107 00:07:28,990 --> 00:07:34,090 ‫in the amount that our access value gives us so we can multiply by the axis value. 108 00:07:34,420 --> 00:07:36,340 ‫And that's going to give us the right result. 109 00:07:36,340 --> 00:07:39,370 ‫So we're going to have the forward vector multiplied by the axis value. 110 00:07:39,370 --> 00:07:44,110 ‫If it's one, we go forward, if it's minus one, a forward vector becomes a backwards vector and we 111 00:07:44,110 --> 00:07:46,240 ‫going backwards with just this one function. 112 00:07:46,240 --> 00:07:49,000 ‫So that's set us up with move forward. 113 00:07:49,000 --> 00:07:49,530 ‫Great. 114 00:07:49,540 --> 00:07:53,470 ‫The next thing is to bind for our look up. 115 00:07:53,470 --> 00:07:54,790 ‫So let's go and copy. 116 00:07:54,790 --> 00:07:58,480 ‫I always like to copy these string references so that I don't make a mistake. 117 00:07:58,930 --> 00:08:02,860 ‫Do a look up and instead of binding to move forward, let's go back to the head of file and create something 118 00:08:02,860 --> 00:08:03,160 ‫new. 119 00:08:03,160 --> 00:08:07,960 ‫It's going to be look up and again, a float axis value. 120 00:08:09,080 --> 00:08:09,770 ‫Like so. 121 00:08:10,600 --> 00:08:15,940 ‫And if I do control shift P and do create implementation goes ahead and saves me a little bit of time. 122 00:08:16,150 --> 00:08:20,980 ‫And this time instead of doing add movement inputs, we want to use one of those other functions that 123 00:08:20,980 --> 00:08:22,330 ‫we had at our disposal. 124 00:08:27,060 --> 00:08:32,580 ‫Namely the ad controller pitch input because we want to pitch up basically. 125 00:08:32,730 --> 00:08:37,080 ‫So this time we can do ad controller. 126 00:08:38,860 --> 00:08:42,550 ‫Pitch inputs and pass in directly the axis value. 127 00:08:42,580 --> 00:08:43,390 ‫Now. 128 00:08:43,420 --> 00:08:49,510 ‫Now be a bit more experienced C++ programmers among you might say, hey, this function basically does 129 00:08:49,510 --> 00:08:49,980 ‫nothing. 130 00:08:49,990 --> 00:08:53,650 ‫It is just calling some other function with the same parameter. 131 00:08:53,650 --> 00:08:55,540 ‫So it's not really doing very much. 132 00:08:55,540 --> 00:08:56,650 ‫And you would be right. 133 00:08:56,650 --> 00:09:03,250 ‫So what we could do is we could do the a shooter character look up so we could call the function that 134 00:09:03,250 --> 00:09:06,700 ‫was defined on this class the a shooter character. 135 00:09:07,270 --> 00:09:13,780 ‫Or we could say, well, there's add control pitch inputs that we could just call that directly, couldn't 136 00:09:13,780 --> 00:09:14,200 ‫we? 137 00:09:14,200 --> 00:09:21,910 ‫So if we use F12 to find out where that's defined and you go and navigate to it, you can see that it 138 00:09:21,910 --> 00:09:24,850 ‫is being defined in actually pawn h. 139 00:09:24,850 --> 00:09:30,340 ‫So if you scroll up, you can see all the way up here somewhere we're going to find a class. 140 00:09:30,340 --> 00:09:34,690 ‫Let's, we could even just search for class space, something like that. 141 00:09:35,430 --> 00:09:38,460 ‫And here we've got a pawn is the class. 142 00:09:38,460 --> 00:09:44,820 ‫So let's go back to the shooter character and what we can try and just make this a little bit shorter 143 00:09:44,850 --> 00:09:53,910 ‫by saying instead let's do a pawn colon, colon, add controller pitch input so that it automatically 144 00:09:53,910 --> 00:09:59,100 ‫just directly calls that parent function rather than having to go via our own function. 145 00:09:59,100 --> 00:10:02,700 ‫This is a valid way to do it as well, but it's just not necessary. 146 00:10:02,700 --> 00:10:08,070 ‫So I'm going to comment it out so that you can refer to it and see it if you wanted to do it that way. 147 00:10:08,190 --> 00:10:12,120 ‫But I would recommend doing it the slightly shorter route like so. 148 00:10:30,820 --> 00:10:35,720 ‫I and in trying to compile it, I noticed that instead of calling behind Axis, as I'd been wanting 149 00:10:35,720 --> 00:10:38,240 ‫to do, I've been doing bind action. 150 00:10:38,240 --> 00:10:41,000 ‫So you've probably been screaming at your screen the whole time. 151 00:10:41,000 --> 00:10:42,530 ‫Let's go ahead and build that again. 152 00:10:42,530 --> 00:10:46,580 ‫By the way, I'm doing that with a control shift B and selecting the build option. 153 00:10:46,580 --> 00:10:53,690 ‫That is the simple shooter editor win 64 development build, which is just a quicker way for me than 154 00:10:53,690 --> 00:10:55,940 ‫going over and hitting the compile button. 155 00:10:57,140 --> 00:10:59,390 ‫I'll look and I can't get my syntax right today. 156 00:10:59,390 --> 00:11:07,070 ‫Of course we need to use the ampersand in front of this function to say basically that we want to get 157 00:11:07,070 --> 00:11:08,540 ‫the pointer. 158 00:11:09,750 --> 00:11:14,610 ‫We want to use the ampersand in front of these functions to actually have the correct syntax here. 159 00:11:21,950 --> 00:11:22,130 ‫Okay. 160 00:11:22,130 --> 00:11:28,430 ‫So after I corrected those two very common errors, one being that I'd got the wrong function call and 161 00:11:28,430 --> 00:11:33,030 ‫the other being that I hadn't got an ampersand in front of the functions I'm trying to use. 162 00:11:33,050 --> 00:11:37,070 ‫Let's go over into Unreal and see whether this is actually working. 163 00:11:37,070 --> 00:11:41,930 ‫If I go ahead and hit play and use the W key and the S key, you can see I can move forward and backwards. 164 00:11:41,930 --> 00:11:42,800 ‫It's amazing. 165 00:11:42,800 --> 00:11:49,040 ‫And with the mouse I can look up and down, but it is feeling inverted at the moment to my movement. 166 00:11:49,040 --> 00:11:54,680 ‫So I'm just going to go over to the product settings and hit minus one in there and go ahead and hit 167 00:11:54,680 --> 00:11:55,310 ‫play. 168 00:11:56,560 --> 00:11:59,140 ‫And now if I go up and down, it feels correct. 169 00:11:59,140 --> 00:12:01,990 ‫Notice that I'm actually spawning in two different locations. 170 00:12:01,990 --> 00:12:04,780 ‫That's because I have to player starts when I put the second one in. 171 00:12:04,780 --> 00:12:08,650 ‫I didn't realize there was already one in the level, which is why I'm sometimes spawning here, sometimes 172 00:12:08,650 --> 00:12:10,120 ‫spawning in a different location. 173 00:12:10,120 --> 00:12:11,500 ‫You might find the same thing. 174 00:12:13,170 --> 00:12:14,940 ‫So it is challenge time. 175 00:12:14,940 --> 00:12:22,260 ‫Let's get you guys binding your movie rights and you'll look right so that we've got full control of 176 00:12:22,260 --> 00:12:22,920 ‫our movement. 177 00:12:22,920 --> 00:12:27,690 ‫So repeat the process that I've just done in the lecture for both of these two and you've probably been 178 00:12:27,690 --> 00:12:28,590 ‫following along. 179 00:12:28,830 --> 00:12:31,320 ‫If not, you can go in and watch to revise. 180 00:12:31,320 --> 00:12:35,340 ‫And also I'd like you to attempt the jump function as well. 181 00:12:35,460 --> 00:12:38,160 ‫If you're feeling brave, pause the video and have a go. 182 00:12:38,920 --> 00:12:39,270 ‫Okay. 183 00:12:39,270 --> 00:12:39,720 ‫Welcome back. 184 00:12:39,720 --> 00:12:41,330 ‫So let's give this a shot. 185 00:12:41,340 --> 00:12:46,680 ‫First of all, we're repeating the above steps for move forward and look up. 186 00:12:46,680 --> 00:12:50,160 ‫So we're going to be having move, right? 187 00:12:50,430 --> 00:12:54,120 ‫And we're going to be having instead of look up, we're going to be having look right. 188 00:12:54,450 --> 00:12:59,520 ‫And we can go ahead and copy these to set up our axes in the project settings. 189 00:12:59,520 --> 00:13:02,160 ‫So add another couple of axes mappings. 190 00:13:02,160 --> 00:13:08,190 ‫The first one is going to be move, right, which I'm going to map to the key, a four left. 191 00:13:08,190 --> 00:13:10,890 ‫So that's going to be the minus one. 192 00:13:11,310 --> 00:13:18,090 ‫A is going to be minus one because it's actually left the opposite of right and DX is going to be four 193 00:13:18,120 --> 00:13:18,990 ‫going right now. 194 00:13:18,990 --> 00:13:21,210 ‫Obviously, you can add in your arrow keys here as well. 195 00:13:21,210 --> 00:13:23,190 ‫I'm just not doing that to save time. 196 00:13:23,190 --> 00:13:25,170 ‫But you can go ahead and do the same thing. 197 00:13:25,170 --> 00:13:31,170 ‫You can just add more keys here, as many keys as you like to map to that single axis look. 198 00:13:31,170 --> 00:13:31,680 ‫Right. 199 00:13:31,680 --> 00:13:35,520 ‫We're going to use the mouse x. 200 00:13:36,310 --> 00:13:39,910 ‫And I think one should be sufficient rather than minus one. 201 00:13:40,180 --> 00:13:41,740 ‫I don't think we have to invert this one. 202 00:13:42,520 --> 00:13:45,610 ‫And then what we're going to do is we're going to bind this slightly differently. 203 00:13:45,610 --> 00:13:52,330 ‫So I'm going to go alt oh to go and create ourselves a move right function here. 204 00:13:53,390 --> 00:13:57,540 ‫Now you might be wondering, why are we doing this differently? 205 00:13:57,560 --> 00:13:58,620 ‫Why is move right? 206 00:13:58,640 --> 00:14:00,860 ‫Why are we not just calling straight to add movement input? 207 00:14:00,950 --> 00:14:02,990 ‫The difference is here we're doing a bit of calculation. 208 00:14:02,990 --> 00:14:07,820 ‫We're adding in this multiplication by a vector, which is adding a bit of information and justifying 209 00:14:07,820 --> 00:14:09,630 ‫the existence for this function. 210 00:14:09,650 --> 00:14:16,030 ‫So this time, instead of getting the act of forward, want to get the actor right vector like so and 211 00:14:16,040 --> 00:14:20,810 ‫multiply it by the axis value and then we want to be calling instead of move forward. 212 00:14:20,810 --> 00:14:24,980 ‫We want to be calling move right now for look. 213 00:14:26,960 --> 00:14:27,680 ‫Right. 214 00:14:27,680 --> 00:14:34,310 ‫Instead of adding the controller pitch input, we want to be doing the your input. 215 00:14:34,310 --> 00:14:36,380 ‫Remember roll pitch and you're from aeroplanes. 216 00:14:36,380 --> 00:14:41,110 ‫You can look it up on Wikipedia if you're not sure which one is which and go ahead and build that one. 217 00:14:41,120 --> 00:14:43,190 ‫Hopefully this time I haven't got the syntax wrong. 218 00:14:43,670 --> 00:14:49,310 ‫Let's dive over to the editor and hit play and there you go. 219 00:14:49,310 --> 00:14:50,510 ‫I can look all the way around me. 220 00:14:50,510 --> 00:14:51,470 ‫That's looking good. 221 00:14:51,470 --> 00:14:53,150 ‫I can strafe left and right. 222 00:14:53,150 --> 00:14:55,010 ‫I can go forward and backwards. 223 00:14:55,010 --> 00:15:01,670 ‫So the thing left for us is jump, which is going to be an action mapping rather than an axis, because 224 00:15:01,670 --> 00:15:05,090 ‫it's a discrete action and I call it jump and copy it. 225 00:15:05,120 --> 00:15:07,640 ‫Go over to Visual Studio code. 226 00:15:08,410 --> 00:15:13,780 ‫And just close down my compile window and here I'm going to instead of binding an axis, you've got 227 00:15:13,780 --> 00:15:13,870 ‫it. 228 00:15:13,870 --> 00:15:18,700 ‫I'm going to be binding a action bind action. 229 00:15:18,710 --> 00:15:19,660 ‫Simple as that. 230 00:15:19,720 --> 00:15:21,940 ‫It's going to start off still with the text here. 231 00:15:22,930 --> 00:15:23,710 ‫Of jump. 232 00:15:24,190 --> 00:15:28,840 ‫But the thing that is different with axes, as you probably remember. 233 00:15:30,860 --> 00:15:38,570 ‫Is we need to use this syntax I input event, which is an enum, which means that it basically can take 234 00:15:38,570 --> 00:15:45,080 ‫a number of these different options, double click, press release, etc. We're going to want to jump 235 00:15:45,080 --> 00:15:48,080 ‫on press like so, so. 236 00:15:55,710 --> 00:16:02,400 ‫So that's I underscore pressed and then once we know that we can go ahead and do the same this and then 237 00:16:02,400 --> 00:16:04,980 ‫we want to be calling to jump. 238 00:16:05,280 --> 00:16:07,700 ‫Now where is jump defined? 239 00:16:07,710 --> 00:16:08,460 ‫Is it in the --? 240 00:16:08,460 --> 00:16:09,330 ‫Let's have a look. 241 00:16:10,320 --> 00:16:13,440 ‫Nope, but it might be in the character. 242 00:16:13,440 --> 00:16:16,230 ‫So I'm going to do a control P and look for character. 243 00:16:20,540 --> 00:16:21,710 ‫Dot H. 244 00:16:23,850 --> 00:16:28,800 ‫Open that up and just have a look through here, see if they have a jump function defined in here. 245 00:16:29,040 --> 00:16:32,990 ‫Jump and then open brackets often is a good way to look for functions within the header files. 246 00:16:33,000 --> 00:16:34,860 ‫Sure enough, we have got that function. 247 00:16:34,860 --> 00:16:36,030 ‫You can see the documentation. 248 00:16:36,030 --> 00:16:40,230 ‫I often like to use the source code directly rather than looking up any documentation files. 249 00:16:40,230 --> 00:16:44,790 ‫I just find it sometimes a lot quicker to access, especially when you have access to control. 250 00:16:44,790 --> 00:16:46,770 ‫P In Visual Studio code. 251 00:16:47,430 --> 00:16:52,620 ‫So what we need to do is instead of going --, colon, colon, we need to do a character colon, colon. 252 00:16:52,620 --> 00:16:56,610 ‫So it is going to be ampersand, a character colon. 253 00:16:56,610 --> 00:16:59,190 ‫Colon This is because that's the class it's defined on. 254 00:16:59,190 --> 00:17:05,280 ‫We can't go looking up the hierarchy when we're doing this colon, colon operator and then it's just 255 00:17:05,280 --> 00:17:05,880 ‫going to be jump. 256 00:17:05,880 --> 00:17:07,830 ‫So character, colon, colon jump. 257 00:17:07,830 --> 00:17:10,560 ‫And don't forget that I need a semicolon on the end of the line. 258 00:17:10,560 --> 00:17:13,890 ‫Go ahead and build and see whether we're able to jump now. 259 00:17:17,430 --> 00:17:19,790 ‫Well, the build worked out correctly. 260 00:17:19,800 --> 00:17:21,810 ‫Let's go over to the sandbox level. 261 00:17:21,810 --> 00:17:24,600 ‫Hit play and try and jump. 262 00:17:24,780 --> 00:17:28,380 ‫I don't have any key bound, so that might hamper me. 263 00:17:28,710 --> 00:17:35,200 ‫Add the space bar in as the key that I want for jump and go ahead and hit play. 264 00:17:35,220 --> 00:17:35,910 ‫Yay. 265 00:17:35,910 --> 00:17:39,750 ‫I'm able to jump up and down and move through the air and move around. 266 00:17:39,870 --> 00:17:40,560 ‫Fantastic. 267 00:17:40,560 --> 00:17:44,760 ‫So we've learnt how to bind our axes and actions where we haven't learnt it. 268 00:17:44,790 --> 00:17:51,300 ‫We have revised it, but we've seen what we want to bind to in a character in order to get that classic 269 00:17:51,300 --> 00:17:58,950 ‫character jumping, strafing, moving and looking with your camera that we all know and love from our 270 00:17:58,950 --> 00:17:59,760 ‫shooters. 271 00:18:00,760 --> 00:18:07,590 ‫And the next lecture will look at the nuances required for moving with a controller, as well as a keyboard 272 00:18:07,590 --> 00:18:08,400 ‫and a mouse.
