1 00:00:03,050 --> 00:00:08,480 In this lecture, we're giving our players some feet so that we can prevent the player from doing many, 2 00:00:08,480 --> 00:00:10,160 many jumps up on a wall. 3 00:00:10,160 --> 00:00:14,660 Before we start on preventing wall jumps to show a quick tweak I've made to my game, my player was 4 00:00:14,660 --> 00:00:16,940 looking a little bit too manic, running around quickly. 5 00:00:16,940 --> 00:00:22,640 I've changed the run speed to seven, the jump speed to 20, and the gravity scale to six, just to 6 00:00:22,640 --> 00:00:24,890 make him calm the heck down a little bit. 7 00:00:24,890 --> 00:00:30,380 So now it's a little bit more floaty, a little bit less super mega speed and a little bit less flying 8 00:00:30,380 --> 00:00:32,060 off into the wall, into the sky. 9 00:00:32,060 --> 00:00:33,170 So I'm pretty happy with that. 10 00:00:33,170 --> 00:00:33,560 Okay. 11 00:00:33,560 --> 00:00:37,520 So in terms of preventing wall jump, I'm going to give this to you as a challenge, see if you can 12 00:00:37,520 --> 00:00:38,330 figure it out. 13 00:00:38,330 --> 00:00:43,040 It's not super difficult, but it requires a little bit of pondering prevent the player from multi jumping 14 00:00:43,040 --> 00:00:44,210 when touching the wall. 15 00:00:44,210 --> 00:00:45,860 That's what we're trying to do in this instance. 16 00:00:45,860 --> 00:00:51,560 A little bit of a hint for you is one way of doing this is to add a second collider to represent feet 17 00:00:51,560 --> 00:00:56,570 and then to do something with that collider different to what we're doing with our capsule collider 18 00:00:56,570 --> 00:00:57,230 around the body. 19 00:00:57,230 --> 00:00:58,700 So there's your challenge. 20 00:00:58,700 --> 00:01:00,470 Have a think about that one and no worries. 21 00:01:00,470 --> 00:01:03,950 If you can't get it, we'll go through it together when you come back from giving it a try. 22 00:01:03,950 --> 00:01:05,810 So pause the video and I'll see you soon. 23 00:01:08,840 --> 00:01:10,340 First step, I'm going to click on the player. 24 00:01:10,340 --> 00:01:10,760 And you know what? 25 00:01:10,760 --> 00:01:12,590 I've not been paying attention to my pre-fab. 26 00:01:12,590 --> 00:01:16,250 Let's apply any of our overrides we've made to the prefab. 27 00:01:16,280 --> 00:01:21,710 That would be a smart thing to do and add a new component which would be a box collider to DH to represent 28 00:01:21,710 --> 00:01:22,390 the feet. 29 00:01:22,420 --> 00:01:25,280 Now what I'm going to do, first of all, I'm going to make these icons a little bit less. 30 00:01:25,280 --> 00:01:26,390 I can't even see the player. 31 00:01:26,390 --> 00:01:27,710 These gizmos are so huge. 32 00:01:27,710 --> 00:01:31,340 So the 3D icons, I'm just going to reduce them down a little bit. 33 00:01:31,340 --> 00:01:36,080 I tend not to pay attention to them anyway, so I'll have them just little there, just in case we need 34 00:01:36,080 --> 00:01:37,460 them so we can see them going on. 35 00:01:37,460 --> 00:01:40,160 But I don't want them to get in the way of being able to see stuff. 36 00:01:40,160 --> 00:01:45,470 So on our player, we currently have a capsule collider two D that's going to stay there because that's 37 00:01:45,470 --> 00:01:46,130 what we need to say. 38 00:01:46,130 --> 00:01:47,750 Don't stick into the walls. 39 00:01:47,750 --> 00:01:49,310 I'm going to make it a little bit wider. 40 00:01:49,310 --> 00:01:51,830 So hit edit collider or click on Edit Collider. 41 00:01:51,830 --> 00:01:54,200 Just stretch it out a little bit, stretch it out a little bit. 42 00:01:54,200 --> 00:01:57,800 And after going and applying that stuff to my prefab, I've kind of done the same thing, haven't I? 43 00:01:57,800 --> 00:01:59,870 I'm working right in my instance. 44 00:01:59,870 --> 00:02:04,970 I'll apply all will go work in the prefab by clicking on the prefab button and these bad habits that 45 00:02:04,970 --> 00:02:08,150 I've got from the olden days where things worked a little different. 46 00:02:08,150 --> 00:02:08,810 But there we go. 47 00:02:08,810 --> 00:02:09,889 There's our capsule collider. 48 00:02:09,889 --> 00:02:14,770 Now, while I'm in my prefab, I'm going to jump down to add component at a box collider to DX. 49 00:02:14,780 --> 00:02:20,900 Click on the edit collider and we'll make this the size of the feet or make this in the feet area so 50 00:02:20,900 --> 00:02:22,310 it doesn't need to be all the way up high. 51 00:02:22,310 --> 00:02:27,020 It just needs to be down at the bottom to say, Are you touching the ground or are you touching a letter 52 00:02:27,050 --> 00:02:28,010 nice and low? 53 00:02:28,010 --> 00:02:30,230 I'm going to bring it inside of the capsule. 54 00:02:30,260 --> 00:02:31,940 Collider So you can see the edge of the capsule. 55 00:02:31,940 --> 00:02:37,010 Collider Here is on the outside and the feet are on the inside because we don't want the feet. 56 00:02:37,010 --> 00:02:40,310 Collider Accidentally touching the wall that we're trying not to grip too. 57 00:02:40,310 --> 00:02:43,430 So I have it on the inside a little bit there, not to too far. 58 00:02:43,460 --> 00:02:45,830 I think that should be okay in terms of our structure. 59 00:02:45,830 --> 00:02:47,390 So now we have two different colliders. 60 00:02:47,390 --> 00:02:48,890 There's other ways that you could do this. 61 00:02:48,890 --> 00:02:53,600 You could have these colliders as children to the player, but this for me is nice and clean. 62 00:02:53,600 --> 00:02:57,020 All of our stuff is on the player at the moment because I'm pretty sure I'm just going to need these 63 00:02:57,020 --> 00:03:01,250 two colliders and we can access in our script the different colliders. 64 00:03:01,250 --> 00:03:02,300 We can say, grab this box. 65 00:03:02,300 --> 00:03:04,070 Collider Or Grab this. 66 00:03:04,070 --> 00:03:04,490 Where are we? 67 00:03:04,490 --> 00:03:05,060 The Capsule? 68 00:03:05,060 --> 00:03:06,590 Collider All the way up here. 69 00:03:06,920 --> 00:03:11,270 Capsule Collider If I wanted to have two or three or four box colliders, I'd need to do it a little 70 00:03:11,270 --> 00:03:11,810 bit differently. 71 00:03:11,810 --> 00:03:16,070 It wouldn't work so well, but simply because this is a different type of component. 72 00:03:16,070 --> 00:03:19,280 Box Collider two DX Versus this, which is a capsule. 73 00:03:19,280 --> 00:03:22,760 Collider two DD We can do it this particular way, but take note. 74 00:03:22,760 --> 00:03:26,270 This wouldn't work if we had to box colitis the way that I'm about to do it. 75 00:03:26,270 --> 00:03:28,820 Now that we've got all that, I'm going to jump over into my script. 76 00:03:28,820 --> 00:03:31,370 We'll have a look for where we currently have our capsule. 77 00:03:31,370 --> 00:03:38,600 Collider two DX I'm just going to rename this from my Capsule Collider to right click Change All Occurrences 78 00:03:38,600 --> 00:03:39,920 or Control f two. 79 00:03:39,950 --> 00:03:45,590 I rename this to be my Body Collider Just so it's really clear in our code what's going on and it's 80 00:03:45,590 --> 00:03:52,730 a capsule collider I'm going to create another one which will be of type box collider to DX and we'll 81 00:03:52,730 --> 00:03:54,800 call this my feet. 82 00:03:55,310 --> 00:03:56,120 Just my feet. 83 00:03:56,120 --> 00:03:57,890 My Feet Collider on my feet. 84 00:03:57,890 --> 00:03:59,270 What's the convention we're doing here? 85 00:03:59,270 --> 00:03:59,690 My feet. 86 00:03:59,690 --> 00:04:04,700 Collider is probably a wiser thing because we've got my body Collider My feet collider And in start 87 00:04:04,700 --> 00:04:05,540 we need to grab that. 88 00:04:05,540 --> 00:04:09,140 So my feet collider equals get component. 89 00:04:09,140 --> 00:04:10,130 What type of component? 90 00:04:10,130 --> 00:04:15,320 It's a box collider two dx excellent de parentheses semicolon. 91 00:04:15,350 --> 00:04:17,390 Now scroll down, have a look where this is relevant. 92 00:04:17,390 --> 00:04:21,140 Currently it's in the jump and in what else? 93 00:04:21,140 --> 00:04:24,320 The climb ladder where we need to know are you touching these things? 94 00:04:24,320 --> 00:04:27,350 So within on jump I'm just going to change from my body. 95 00:04:27,350 --> 00:04:29,630 Collider To my feet. 96 00:04:29,630 --> 00:04:32,000 Collider That's what we're interested in. 97 00:04:32,000 --> 00:04:34,250 Same thing down here and climb ladder instead of my body. 98 00:04:34,250 --> 00:04:36,320 Collider Be my feet. 99 00:04:36,410 --> 00:04:38,060 Collider Save. 100 00:04:38,060 --> 00:04:39,050 That should have changed it. 101 00:04:39,050 --> 00:04:45,470 Now we should be assessing, jumping and climbing based upon whether this particular box collider is 102 00:04:45,470 --> 00:04:48,920 touching as opposed to whether our capsule collider is touching. 103 00:04:48,920 --> 00:04:53,680 Scroll out a little bit, jump out of the prefab, click on play. 104 00:04:54,980 --> 00:04:57,200 First test is can we actually run around and move? 105 00:04:57,200 --> 00:04:57,800 We can. 106 00:04:57,800 --> 00:04:59,300 Can I jump? 107 00:04:59,300 --> 00:04:59,870 Double jump. 108 00:04:59,870 --> 00:05:01,160 I'm tapping on the spacebar. 109 00:05:01,160 --> 00:05:02,120 I cannot double jump. 110 00:05:02,120 --> 00:05:02,540 Perfect. 111 00:05:02,540 --> 00:05:04,190 So we stopped the double jump. 112 00:05:04,190 --> 00:05:05,780 Can I still do my bouncy bounce? 113 00:05:05,780 --> 00:05:06,500 Yes, I can. 114 00:05:06,500 --> 00:05:07,700 And can I climb a ladder? 115 00:05:07,700 --> 00:05:08,240 Yes, I can. 116 00:05:08,240 --> 00:05:12,590 So I've got all the functionality in there that we needed and we've stopped the wall jump, we've stopped 117 00:05:12,590 --> 00:05:15,030 the grittiness in the last lecture and we've got some bounce. 118 00:05:15,050 --> 00:05:15,390 There we go. 119 00:05:15,410 --> 00:05:16,520 Pretty happy with the character. 120 00:05:16,520 --> 00:05:18,830 And as I said at the start, I've tuned it a little bit. 121 00:05:18,830 --> 00:05:20,810 So make sure you take time to tune your character. 122 00:05:20,810 --> 00:05:21,680 So it feels good. 123 00:05:21,680 --> 00:05:25,100 But I think for now we've got most of our character movement functionality. 124 00:05:25,100 --> 00:05:25,910 Feeling good. 125 00:05:25,910 --> 00:05:27,320 Okay, I'll see you in the next lecture.
