1 00:00:00,000 --> 00:00:00,000 Hello, guys. 2 00:00:00,000 --> 00:00:04,000 In this video, we're going to make a large claim, and it's a bit complicated. 3 00:00:04,000 --> 00:00:05,000 In my opinion. 4 00:00:05,000 --> 00:00:10,000 It is hardest part of the course, but I'll walk you through it step by step, and you will know this 5 00:00:10,000 --> 00:00:11,000 mechanic top to bottom. 6 00:00:11,000 --> 00:00:14,000 So I'm sure it will be very simple to understand. 7 00:00:14,000 --> 00:00:16,000 Don't worry about that. 8 00:00:16,000 --> 00:00:21,000 So first let me delete all of the prototyping I did, and then I'm going to show it to you how we do 9 00:00:21,000 --> 00:00:22,000 it step by step. 10 00:00:22,000 --> 00:00:23,000 All right. 11 00:00:23,000 --> 00:00:24,000 I think I'm ready. 12 00:00:24,000 --> 00:00:26,000 So let's begin with simple. 13 00:00:26,000 --> 00:00:27,000 Let's just create animation. 14 00:00:27,000 --> 00:00:35,000 First, we're going to select the player animation, create a new clip, and it's going to be player 15 00:00:35,000 --> 00:00:37,000 ledge climb. 16 00:00:37,000 --> 00:00:40,000 All right, we have it now. 17 00:00:40,000 --> 00:00:43,000 Let's go to graphics, fine player. 18 00:00:44,000 --> 00:00:47,000 Let's climb and drag all of the sprites to the left. 19 00:00:48,000 --> 00:00:51,000 Let's try sample rate 15, see how it works. 20 00:00:52,000 --> 00:00:53,000 Um. 21 00:00:54,000 --> 00:00:54,000 No. 22 00:00:55,000 --> 00:00:55,000 Probably. 23 00:00:55,000 --> 00:00:57,000 Let's see how it will be in the game. 24 00:00:57,000 --> 00:00:59,000 If anything, we can fix it. 25 00:00:59,000 --> 00:01:02,000 Now, let's go to animations, find animation. 26 00:01:02,000 --> 00:01:09,000 Let's climb and check loop time over here, and we can go to animator setup animation. 27 00:01:09,000 --> 00:01:14,000 We need the boolean for that so I can climb. 28 00:01:15,000 --> 00:01:18,000 We're going to move it over here and there's going to be a bit different. 29 00:01:18,000 --> 00:01:22,000 We're going to transfer to a ledge, climb from any state. 30 00:01:23,000 --> 00:01:30,000 If can claim true and now can claim somewhere below, let's just drag it here to the top. 31 00:01:31,000 --> 00:01:35,000 Now, if you add conditions, it will be at the top so I can climb through. 32 00:01:36,000 --> 00:01:37,000 Let's go to settings. 33 00:01:39,000 --> 00:01:44,000 Exit time and check duration is zero and make sure to check and transit to self. 34 00:01:44,000 --> 00:01:45,000 It's very important. 35 00:01:45,000 --> 00:01:53,000 Now we can make another transition to idle move and this will be exit time one duration zero and no 36 00:01:53,000 --> 00:01:54,000 condition to exit. 37 00:01:54,000 --> 00:01:55,000 That's it. 38 00:01:56,000 --> 00:01:58,000 Basically, we're done for the animator. 39 00:01:58,000 --> 00:02:01,000 Now we can forget about it for the time being. 40 00:02:01,000 --> 00:02:03,000 And I want to explain a bit how it's going to work. 41 00:02:04,000 --> 00:02:10,000 So we're going to do edge detection, but we're not going to do it from the player script like we did 42 00:02:10,000 --> 00:02:11,000 before. 43 00:02:12,000 --> 00:02:18,000 If you remember, we have this check collision function where we do in all detection we need. 44 00:02:18,000 --> 00:02:20,000 But let's detection. 45 00:02:20,000 --> 00:02:21,000 I want to do from another object. 46 00:02:21,000 --> 00:02:23,000 I want to do it from the child object. 47 00:02:23,000 --> 00:02:26,000 We have a reason to that and you'll know it in a minute. 48 00:02:27,000 --> 00:02:32,000 Let's go all the way up and in the collision info I want to create public boolean. 49 00:02:33,000 --> 00:02:34,000 Bull. 50 00:02:35,000 --> 00:02:39,000 Ledge detect it, but I don't want to see it in the inspector. 51 00:02:39,000 --> 00:02:43,000 I just need it public so I can access it from another script. 52 00:02:43,000 --> 00:02:47,000 But I want to keep it hidden so it will be hiding the inspector over here. 53 00:02:48,000 --> 00:02:49,000 All right, cool. 54 00:02:49,000 --> 00:02:50,000 We can move it up here. 55 00:02:51,000 --> 00:02:53,000 And now let's create ledge detection first. 56 00:02:53,000 --> 00:02:56,000 I guess I changed my world check size. 57 00:02:56,000 --> 00:02:58,000 Check If it's the same to yours. 58 00:02:58,000 --> 00:03:01,000 -0.3 Now, you can fix it if you want. 59 00:03:01,000 --> 00:03:04,000 Now we're going to create empty object. 60 00:03:04,000 --> 00:03:07,000 I'm going to call it large check. 61 00:03:09,000 --> 00:03:17,000 We're going to add component new script, ledge detection, and we can go inside of this script. 62 00:03:17,000 --> 00:03:18,000 All right. 63 00:03:18,000 --> 00:03:23,000 So what we need for let's check, we need to know position and for the position we're going to use. 64 00:03:23,000 --> 00:03:24,000 Exactly. 65 00:03:24,000 --> 00:03:26,000 The child object itself. 66 00:03:26,000 --> 00:03:27,000 This one. 67 00:03:27,000 --> 00:03:28,000 Right. 68 00:03:28,000 --> 00:03:30,000 This is going to be our position for. 69 00:03:30,000 --> 00:03:30,000 Let's check. 70 00:03:30,000 --> 00:03:32,000 Then we need read use for check. 71 00:03:32,000 --> 00:03:35,000 So I serialize field private float. 72 00:03:35,000 --> 00:03:38,000 We can call it just radius and basically that's it. 73 00:03:38,000 --> 00:03:46,000 So first I want to draw gizmos so we can visualize it on draw gizmos Gizmos to draw wire sphere from 74 00:03:46,000 --> 00:03:50,000 transform position in a radius. 75 00:03:50,000 --> 00:03:51,000 Yes. 76 00:03:52,000 --> 00:03:53,000 Let's go and see this. 77 00:03:53,000 --> 00:04:01,000 We're going to increase radios to something like point two, and I want to place it somewhere above. 78 00:04:02,000 --> 00:04:08,000 Maybe right here, just like in front of the head of the player where? 79 00:04:08,000 --> 00:04:08,000 Let's check. 80 00:04:08,000 --> 00:04:10,000 Possibly it could be all right. 81 00:04:10,000 --> 00:04:11,000 So I think this is fine. 82 00:04:11,000 --> 00:04:13,000 Somewhere in front of the head. 83 00:04:13,000 --> 00:04:15,000 Don't worry about precise placement. 84 00:04:15,000 --> 00:04:17,000 It's not so important. 85 00:04:17,000 --> 00:04:19,000 So now we have let's check position. 86 00:04:19,000 --> 00:04:21,000 We know area we detected. 87 00:04:21,000 --> 00:04:23,000 Now it's time to create. 88 00:04:23,000 --> 00:04:28,000 Let's check itself and I don't want to create boolean here for edge detected. 89 00:04:28,000 --> 00:04:29,000 I want to use boolean. 90 00:04:29,000 --> 00:04:32,000 We just create it on the player which we made public. 91 00:04:32,000 --> 00:04:36,000 So let's go back to edge detection, get access to the player. 92 00:04:37,000 --> 00:04:41,000 Serialize field, Private player player. 93 00:04:41,000 --> 00:04:42,000 Sorry. 94 00:04:43,000 --> 00:04:51,000 And then in the update we're going to do player dot slash detected equals to physics to DX, and here 95 00:04:51,000 --> 00:04:52,000 it's all the same. 96 00:04:52,000 --> 00:04:55,000 You see, basically we do in what we did here check collision. 97 00:04:55,000 --> 00:05:00,000 Very same stuff just from another script and our lab circle. 98 00:05:02,000 --> 00:05:02,000 Right. 99 00:05:02,000 --> 00:05:05,000 Over lap circle. 100 00:05:06,000 --> 00:05:08,000 From transfer position. 101 00:05:09,000 --> 00:05:11,000 In the radius. 102 00:05:12,000 --> 00:05:20,000 Och now I want to go to player and just debug ledge, detect it, debug that log ledge, detect it. 103 00:05:21,000 --> 00:05:28,000 We need to say what is clear so we can just drag it like this and we're going to go to play mode. 104 00:05:28,000 --> 00:05:30,000 Oh, no, I forgot something important. 105 00:05:30,000 --> 00:05:31,000 Guys. 106 00:05:31,000 --> 00:05:33,000 We need a layer for this. 107 00:05:33,000 --> 00:05:33,000 Right. 108 00:05:34,000 --> 00:05:35,000 I hope you did notice before me. 109 00:05:35,000 --> 00:05:37,000 Serialize field pry. 110 00:05:37,000 --> 00:05:39,000 What layer mask? 111 00:05:39,000 --> 00:05:42,000 What is ground? 112 00:05:43,000 --> 00:05:43,000 Okay. 113 00:05:43,000 --> 00:05:45,000 And we're going to do check radius. 114 00:05:45,000 --> 00:05:47,000 And what is ground is a layer mask. 115 00:05:48,000 --> 00:05:50,000 Now, let's go back and check this. 116 00:05:58,000 --> 00:05:59,000 You're going to go to play mode. 117 00:06:00,000 --> 00:06:05,000 We need to choose what is ground and better do it out of play mode. 118 00:06:06,000 --> 00:06:09,000 So now we have console that says false. 119 00:06:09,000 --> 00:06:14,000 If I drag my ground like this to the circle now it says true only. 120 00:06:14,000 --> 00:06:20,000 And by the way, if your console looks like this, you can just click button collapse and it will collapse 121 00:06:20,000 --> 00:06:20,000 the messages. 122 00:06:21,000 --> 00:06:22,000 So now it is true. 123 00:06:22,000 --> 00:06:25,000 If I move it out, let me make it smaller. 124 00:06:25,000 --> 00:06:25,000 Right. 125 00:06:29,000 --> 00:06:31,000 So now let's just detect it. 126 00:06:31,000 --> 00:06:31,000 True. 127 00:06:31,000 --> 00:06:33,000 If I move it out, it is false. 128 00:06:33,000 --> 00:06:39,000 But what if we detect ledge like that when we face a long wall? 129 00:06:39,000 --> 00:06:40,000 Watch this. 130 00:06:40,000 --> 00:06:41,000 This is pretty long. 131 00:06:41,000 --> 00:06:42,000 All right. 132 00:06:42,000 --> 00:06:44,000 And we place it here. 133 00:06:45,000 --> 00:06:48,000 It says true, but it is not the ledge. 134 00:06:48,000 --> 00:06:49,000 It is just a wall. 135 00:06:49,000 --> 00:06:52,000 So we have a way to control that. 136 00:06:52,000 --> 00:06:53,000 How are we going to do that? 137 00:06:53,000 --> 00:06:59,000 We're going to disable Let's check if there is a wall in front of us. 138 00:07:00,000 --> 00:07:06,000 And if there is no wall in front or above and only below, then we're going to know it is a ledge. 139 00:07:07,000 --> 00:07:07,000 How are we going to do that? 140 00:07:07,000 --> 00:07:09,000 I'm going to show you right now. 141 00:07:09,000 --> 00:07:13,000 And let's select, let's check, choose what is ground, because I didn't do it before. 142 00:07:13,000 --> 00:07:19,000 And we're going to add component box Collider that we're going to make is trigger and we're going to 143 00:07:19,000 --> 00:07:21,000 use on trigger enter. 144 00:07:21,000 --> 00:07:24,000 If you never faced an trigger enter before, don't worry. 145 00:07:24,000 --> 00:07:27,000 Later in the course, we're going to discuss it deeply. 146 00:07:27,000 --> 00:07:29,000 I would say for now we're just going to use it. 147 00:07:29,000 --> 00:07:30,000 You just follow me. 148 00:07:30,000 --> 00:07:32,000 And it's not complicated, honestly. 149 00:07:32,000 --> 00:07:39,000 So this is a collider we have here, and we can turn this collider into a trigger. 150 00:07:39,000 --> 00:07:43,000 And when something enters the collider, we can make something happen. 151 00:07:43,000 --> 00:07:46,000 So that is basically called on trigger enter. 152 00:07:46,000 --> 00:07:48,000 Now we have this trigger, right? 153 00:07:49,000 --> 00:07:54,000 I'm going to make it like this and I'm going to go to ledge detection back again. 154 00:07:55,000 --> 00:08:00,000 Create a boolean private bool can detect. 155 00:08:01,000 --> 00:08:10,000 Now let's go over here and create a function which is called on trigger Enter to DX over here. 156 00:08:10,000 --> 00:08:20,000 Now, what we do here, we say if collision dot game object, dot layer equals equals to layer mask 157 00:08:20,000 --> 00:08:21,000 dot. 158 00:08:22,000 --> 00:08:30,000 Name to layer so we can get a layer by name and in the parentheses and quotation marks we should say 159 00:08:30,000 --> 00:08:35,000 ground and please be sure it is named same as an layer in unity. 160 00:08:35,000 --> 00:08:37,000 You can check it. 161 00:08:38,000 --> 00:08:39,000 Over here. 162 00:08:39,000 --> 00:08:42,000 If you go to layers over here, ground, right. 163 00:08:42,000 --> 00:08:44,000 So name should be saved. 164 00:08:44,000 --> 00:08:48,000 And let's go back and we do this on trigger enter. 165 00:08:48,000 --> 00:08:52,000 If layer is ground, then can detect equals to false. 166 00:08:52,000 --> 00:08:57,000 Now we're going to create another on trigger but exit on trigger exit to the. 167 00:08:58,000 --> 00:09:00,000 And we're going to copy these two lines. 168 00:09:02,000 --> 00:09:05,000 Paste it in here, but make it true. 169 00:09:06,000 --> 00:09:08,000 Then we're going to update. 170 00:09:09,000 --> 00:09:13,000 And we say if can detect, then we do this detection. 171 00:09:13,000 --> 00:09:14,000 Pretty simple. 172 00:09:14,000 --> 00:09:16,000 Now, let's try it again. 173 00:09:16,000 --> 00:09:19,000 I will take my inspector and I'll turn it into debug mode. 174 00:09:19,000 --> 00:09:22,000 So we can see, can detect boolean. 175 00:09:22,000 --> 00:09:24,000 Now, look, if I take my ground. 176 00:09:25,000 --> 00:09:27,000 And I'll make it something like this. 177 00:09:27,000 --> 00:09:29,000 Move it in front of the character. 178 00:09:31,000 --> 00:09:35,000 Now let me look the ledger check so we can see it. 179 00:09:35,000 --> 00:09:35,000 Click. 180 00:09:35,000 --> 00:09:36,000 Look over here. 181 00:09:38,000 --> 00:09:39,000 Now check this out. 182 00:09:39,000 --> 00:09:44,000 If I enter, the trigger from this side can detect turns to false. 183 00:09:45,000 --> 00:09:47,000 You watch this one, right? 184 00:09:47,000 --> 00:09:50,000 If I move it out, can detect equals to true. 185 00:09:51,000 --> 00:09:56,000 If I make it long and place it like this again, can detect false. 186 00:09:57,000 --> 00:10:01,000 But if it is a wall and we say. 187 00:10:02,000 --> 00:10:04,000 Move it from below. 188 00:10:05,000 --> 00:10:08,000 It does not switch off can detect boolean. 189 00:10:08,000 --> 00:10:12,000 And actually you can see here that our alleged detection became true. 190 00:10:12,000 --> 00:10:14,000 It is happening because of the collider. 191 00:10:14,000 --> 00:10:20,000 We said before, if I go back to normal mode and click edit on my collider, you see how it is set. 192 00:10:20,000 --> 00:10:27,000 So if we enter this trigger from the right top or left side and actually we do need left side, only 193 00:10:27,000 --> 00:10:28,000 right side. 194 00:10:28,000 --> 00:10:28,000 Yeah. 195 00:10:28,000 --> 00:10:32,000 Anyway, we said can detect to false and we are no longer able to detect. 196 00:10:32,000 --> 00:10:36,000 But if we move in platform from the bottom, where is it. 197 00:10:36,000 --> 00:10:36,000 Yeah. 198 00:10:36,000 --> 00:10:43,000 You can see that this ground platform entered the alleged detection before it entered the trigger. 199 00:10:43,000 --> 00:10:45,000 So it is able to detect. 200 00:10:45,000 --> 00:10:46,000 I hope that makes sense. 201 00:10:46,000 --> 00:10:51,000 If it's still a bit confusing to you, please don't worry with the time, it will be super simple to 202 00:10:51,000 --> 00:10:51,000 understand. 203 00:10:51,000 --> 00:10:52,000 All right. 204 00:10:52,000 --> 00:10:55,000 So as of now, let's just make sure our detection is working. 205 00:10:55,000 --> 00:10:57,000 I'm going to clear it. 206 00:10:57,000 --> 00:11:06,000 And if I place my role like this false if I go from the top false. 207 00:11:06,000 --> 00:11:08,000 But if I go from the bottom. 208 00:11:09,000 --> 00:11:09,000 True. 209 00:11:10,000 --> 00:11:11,000 The true goes right. 210 00:11:11,000 --> 00:11:17,000 If I place my role like this and I move my character, let's say, to the wall and then he is jumping, 211 00:11:18,000 --> 00:11:19,000 it is false. 212 00:11:19,000 --> 00:11:21,000 False, false, false, false, false, false. 213 00:11:21,000 --> 00:11:22,000 And then boom, true. 214 00:11:22,000 --> 00:11:23,000 Let's detect it. 215 00:11:23,000 --> 00:11:24,000 Perfect. 216 00:11:24,000 --> 00:11:29,000 Next we go into freeze the player at the position of let's check. 217 00:11:30,000 --> 00:11:31,000 Let's delete this debug. 218 00:11:33,000 --> 00:11:37,000 Go to the top and we're going to create another header. 219 00:11:37,000 --> 00:11:39,000 Header Ledge info. 220 00:11:40,000 --> 00:11:45,000 Now foliage in four info we need offset and I'm going to explain why in a minute. 221 00:11:45,000 --> 00:11:47,000 For now, just repeat after me. 222 00:11:48,000 --> 00:11:51,000 Try what vector to offset. 223 00:11:54,000 --> 00:12:00,000 One and then serialize field private vector to offset to OC. 224 00:12:01,000 --> 00:12:02,000 Now we need. 225 00:12:03,000 --> 00:12:10,000 Another vector too, and it can be just private without serialize field, private vector to climb, 226 00:12:10,000 --> 00:12:19,000 begun position and then private vector to climb over position. 227 00:12:19,000 --> 00:12:20,000 Cool. 228 00:12:20,000 --> 00:12:22,000 Now we need couple of booleans. 229 00:12:22,000 --> 00:12:28,000 First one will be private bool can grab, which means can grab the ledge. 230 00:12:28,000 --> 00:12:34,000 Maybe we should write it can grab ledge and then another boolean private bool can climb. 231 00:12:35,000 --> 00:12:37,000 All right, we have all set. 232 00:12:37,000 --> 00:12:43,000 Now let's go and create a function over here that's going to be named as private void. 233 00:12:43,000 --> 00:12:45,000 Check for ledge. 234 00:12:47,000 --> 00:12:47,000 Inside. 235 00:12:47,000 --> 00:12:52,000 What we're going to do is to check if ledge detect it. 236 00:12:52,000 --> 00:12:58,000 And you remember we said this pledge detected with alleged detection from the child over here. 237 00:12:58,000 --> 00:13:02,000 So now if ledge detect it and. 238 00:13:02,000 --> 00:13:04,000 Can grab lunch. 239 00:13:05,000 --> 00:13:08,000 Then we're going to set can grab lunch to force. 240 00:13:08,000 --> 00:13:10,000 So it happens only once. 241 00:13:10,000 --> 00:13:10,000 False. 242 00:13:10,000 --> 00:13:15,000 Then we need to assign position before climb and after climb. 243 00:13:15,000 --> 00:13:16,000 Maybe. 244 00:13:16,000 --> 00:13:20,000 Let's step aside and I'll explain to you why we need position before and after. 245 00:13:20,000 --> 00:13:22,000 All right, Just for a second. 246 00:13:22,000 --> 00:13:23,000 So check this out. 247 00:13:23,000 --> 00:13:26,000 We have Let me find it platform. 248 00:13:28,000 --> 00:13:33,000 So at the moment we detect in the ledge we're going to freeze position of the player at the place where 249 00:13:33,000 --> 00:13:35,000 ledge was detected right here. 250 00:13:36,000 --> 00:13:42,000 Then we're going to play an animation of a ledge climb from the first frame. 251 00:13:44,000 --> 00:13:45,000 Just like this. 252 00:13:46,000 --> 00:13:53,000 And at the first frame of this animation, we're going to assign position that we are about to create 253 00:13:53,000 --> 00:13:55,000 position before a client. 254 00:13:55,000 --> 00:13:57,000 And it should be somewhere here. 255 00:13:57,000 --> 00:13:59,000 So it looks properly, right? 256 00:13:59,000 --> 00:14:01,000 So this is our position before client. 257 00:14:02,000 --> 00:14:03,000 Then we're going to play animation. 258 00:14:04,000 --> 00:14:10,000 And when animation is over, we're going to move position of the character to position after client 259 00:14:10,000 --> 00:14:14,000 and we're going to play idle animation and it's going to be just perfect. 260 00:14:14,000 --> 00:14:15,000 So let's go back first. 261 00:14:15,000 --> 00:14:17,000 Let's get position of the ledge check. 262 00:14:17,000 --> 00:14:28,000 So we're going to do vector to ledge position equals to get component in children ledge detection transform 263 00:14:28,000 --> 00:14:29,000 dot position. 264 00:14:30,000 --> 00:14:40,000 Now we're going to do this climb began position equals to ledge position plus of set one, then climb 265 00:14:40,000 --> 00:14:41,000 over. 266 00:14:41,000 --> 00:14:46,000 Position equals to ledge position plus offset. 267 00:14:46,000 --> 00:14:52,000 Now we're going to set can claim to true and we're going to create another if statement that says if 268 00:14:52,000 --> 00:14:59,000 can claim true, then transform position equals to climb begun position. 269 00:14:59,000 --> 00:15:00,000 So what are we doing here? 270 00:15:01,000 --> 00:15:06,000 Basically, if let's detect it and we can grab the ledge, then we grab in the ledge. 271 00:15:06,000 --> 00:15:13,000 We're saying we can no longer grab the ledge, we get in position of the ledge itself. 272 00:15:13,000 --> 00:15:19,000 Then we set in position before climb began and we set in position after climb is over with the help 273 00:15:19,000 --> 00:15:21,000 of the ledge position and the offset. 274 00:15:21,000 --> 00:15:23,000 Then we're saying that we have position. 275 00:15:23,000 --> 00:15:26,000 We can no longer grab the edge, but we can climb. 276 00:15:26,000 --> 00:15:28,000 So we set it to true. 277 00:15:28,000 --> 00:15:35,000 And then if we can climb, if this boolean is true, then we hold in position of the player at the climb 278 00:15:35,000 --> 00:15:36,000 began position. 279 00:15:36,000 --> 00:15:42,000 Now I only want to check if can grab ledge is true because we never set it to true at first place. 280 00:15:43,000 --> 00:15:44,000 Okay, Over here. 281 00:15:44,000 --> 00:15:46,000 We need to make it true by default. 282 00:15:46,000 --> 00:15:49,000 If you don't write anything here, then default value will be false. 283 00:15:49,000 --> 00:15:52,000 If you want to make it true by default, we need to do it. 284 00:15:52,000 --> 00:15:53,000 Okay, cool. 285 00:15:53,000 --> 00:15:56,000 Now let's go back and see if this working. 286 00:15:56,000 --> 00:15:57,000 And I'm pretty sure it is. 287 00:15:58,000 --> 00:16:02,000 I'm going to select my level part and just add another platform. 288 00:16:04,000 --> 00:16:05,000 Okay. 289 00:16:05,000 --> 00:16:06,000 Let's go to play mode. 290 00:16:06,000 --> 00:16:11,000 Now, if I'll jump, we can see I stuck in the position of the ledge. 291 00:16:11,000 --> 00:16:12,000 And this is perfect. 292 00:16:12,000 --> 00:16:14,000 This is exactly what we need. 293 00:16:14,000 --> 00:16:16,000 Now, let's do this. 294 00:16:16,000 --> 00:16:18,000 Let's go to graphics. 295 00:16:18,000 --> 00:16:19,000 Fine player. 296 00:16:20,000 --> 00:16:21,000 Climb. 297 00:16:21,000 --> 00:16:23,000 We're going to take first pride and drag it here. 298 00:16:23,000 --> 00:16:30,000 Then we're going to go to Idol, Take first pride, drag it here and select both of them. 299 00:16:30,000 --> 00:16:33,000 We're going to change certain layer so we can see it. 300 00:16:33,000 --> 00:16:36,000 And now we need to define offset of the player how we can do it. 301 00:16:36,000 --> 00:16:39,000 We can just take this two sprites, make them child of the player. 302 00:16:39,000 --> 00:16:44,000 Then let's take the first one, drag it so we can see it. 303 00:16:44,000 --> 00:16:45,000 And I cannot actually see. 304 00:16:45,000 --> 00:16:49,000 So maybe I will switch off sprite of the player. 305 00:16:51,000 --> 00:16:52,000 Okay. 306 00:16:52,000 --> 00:16:56,000 He should be placed somewhere here. 307 00:16:56,000 --> 00:16:58,000 This looks okay. 308 00:16:58,000 --> 00:17:06,000 Now let's go to Notepad and we're going to type before climb X is minus point five. 309 00:17:06,000 --> 00:17:15,000 We can see that we're here in the corner, minus point five, F and Y is -1.2. 310 00:17:15,000 --> 00:17:17,000 So this is how he should be. 311 00:17:17,000 --> 00:17:18,000 Before we climb. 312 00:17:18,000 --> 00:17:22,000 Then let's take a second Sprite and define how he should be after climb. 313 00:17:23,000 --> 00:17:27,000 We're going to place him somewhere here in a proper position. 314 00:17:29,000 --> 00:17:30,000 Then we can see position here. 315 00:17:30,000 --> 00:17:33,000 Point 57 and 1.3. 316 00:17:33,000 --> 00:17:34,000 Let's go to Notepad. 317 00:17:34,000 --> 00:17:36,000 After climb. 318 00:17:38,000 --> 00:17:46,000 X 1.7 fy1 .33 f oc Cool. 319 00:17:50,000 --> 00:17:52,000 Now let's uncheck play mode. 320 00:17:52,000 --> 00:17:57,000 Go to player and write these two offsets minus. 321 00:17:59,000 --> 00:18:00,000 Minus five. 322 00:18:02,000 --> 00:18:03,000 Here. 323 00:18:03,000 --> 00:18:06,000 -1.23. 324 00:18:08,000 --> 00:18:13,000 Here, point 57 and here, 1.33. 325 00:18:13,000 --> 00:18:18,000 And again, your values can be different from mine. 326 00:18:18,000 --> 00:18:18,000 All right. 327 00:18:18,000 --> 00:18:22,000 If you place the alleged check, just not where I did. 328 00:18:22,000 --> 00:18:26,000 If your position is not the same, then your offset might be a bit different. 329 00:18:26,000 --> 00:18:29,000 That's why we using this picture to define offset. 330 00:18:29,000 --> 00:18:30,000 All right. 331 00:18:30,000 --> 00:18:34,000 That's why we place it like that so we can see where he is going to be. 332 00:18:34,000 --> 00:18:36,000 So you do not look at my numbers? 333 00:18:36,000 --> 00:18:39,000 Of course you can check my numbers, but you do not check my numbers. 334 00:18:39,000 --> 00:18:42,000 You go to play mode just like I did. 335 00:18:42,000 --> 00:18:47,000 And you grab the ledge first, just like I did. 336 00:18:48,000 --> 00:18:48,000 Sorry. 337 00:18:48,000 --> 00:18:50,000 Already doing it with the offset? 338 00:18:50,000 --> 00:18:51,000 Yeah. 339 00:18:51,000 --> 00:18:52,000 No, Let me put zero zero here. 340 00:18:58,000 --> 00:19:00,000 So you grab the ledge just like I did. 341 00:19:00,000 --> 00:19:07,000 Then you go to graphics ledge, climb, find this sprite, make it certain layer player and place it 342 00:19:07,000 --> 00:19:09,000 somewhere so you can see it. 343 00:19:11,000 --> 00:19:12,000 Yeah. 344 00:19:12,000 --> 00:19:18,000 Make sure it's a child of the player so we know the offset actually plays it how you want it to be. 345 00:19:18,000 --> 00:19:19,000 Just like this. 346 00:19:20,000 --> 00:19:21,000 Then check the numbers. 347 00:19:21,000 --> 00:19:23,000 You see now, these numbers are different. 348 00:19:23,000 --> 00:19:29,000 Not the same I wrote before, so you need to check it by yourself and then you write it here. 349 00:19:30,000 --> 00:19:34,000 OC Okay, so what is it, minus four or five? 350 00:19:34,000 --> 00:19:35,000 Eight? 351 00:19:35,000 --> 00:19:35,000 Yeah. 352 00:19:37,000 --> 00:19:41,000 It's the Y and this is minus four, five, eight. 353 00:19:42,000 --> 00:19:42,000 Okay. 354 00:19:43,000 --> 00:19:45,000 Now, I don't need this notepad anymore. 355 00:19:46,000 --> 00:19:47,000 Close it. 356 00:19:47,000 --> 00:19:51,000 Let's go back to code and set animator. 357 00:19:52,000 --> 00:19:55,000 We need to find animation controllers. 358 00:19:56,000 --> 00:19:59,000 And here we said Anim, said bull. 359 00:20:01,000 --> 00:20:02,000 Can claim. 360 00:20:03,000 --> 00:20:05,000 Two can claim. 361 00:20:10,000 --> 00:20:10,000 Okay. 362 00:20:10,000 --> 00:20:11,000 Save it. 363 00:20:11,000 --> 00:20:12,000 Let's go. 364 00:20:25,000 --> 00:20:27,000 We're about to be done, actually. 365 00:20:29,000 --> 00:20:30,000 Och, this is good. 366 00:20:31,000 --> 00:20:35,000 What happens here is transition between two animations over and over again. 367 00:20:35,000 --> 00:20:37,000 If you go to animator, you can see it. 368 00:20:37,000 --> 00:20:41,000 So to stop this, we just need to add one condition. 369 00:20:41,000 --> 00:20:47,000 Let's go to this condition and add plus can climb should be false. 370 00:20:47,000 --> 00:20:52,000 If you want the transfer to jump fall from any state can climb should be false. 371 00:20:52,000 --> 00:20:54,000 Now let's go to play mode. 372 00:20:59,000 --> 00:21:00,000 Cool, right? 373 00:21:00,000 --> 00:21:02,000 Mine looks nice. 374 00:21:02,000 --> 00:21:04,000 I hope yours as well. 375 00:21:04,000 --> 00:21:05,000 Good. 376 00:21:05,000 --> 00:21:10,000 Now, what we do next is we need to stop this animation, and we need to actually change position of 377 00:21:10,000 --> 00:21:11,000 the player. 378 00:21:11,000 --> 00:21:12,000 How to do that? 379 00:21:12,000 --> 00:21:12,000 Very simple. 380 00:21:12,000 --> 00:21:14,000 Let's go back to code. 381 00:21:17,000 --> 00:21:21,000 Maybe right above the Czech village, we're going to create private void. 382 00:21:21,000 --> 00:21:22,000 I know. 383 00:21:22,000 --> 00:21:23,000 You know what? 384 00:21:23,000 --> 00:21:23,000 Let's do it below. 385 00:21:23,000 --> 00:21:25,000 I want to do it below. 386 00:21:25,000 --> 00:21:26,000 Just here. 387 00:21:27,000 --> 00:21:29,000 Private void. 388 00:21:30,000 --> 00:21:31,000 Let. 389 00:21:31,000 --> 00:21:31,000 And. 390 00:21:34,000 --> 00:21:34,000 Yeah. 391 00:21:34,000 --> 00:21:34,000 Yeah. 392 00:21:34,000 --> 00:21:36,000 Let's climb over. 393 00:21:36,000 --> 00:21:38,000 And inside we're going to do. 394 00:21:40,000 --> 00:21:50,000 Can claim false because claim is over, then we're going to do transform position equals to claim over 395 00:21:50,000 --> 00:21:53,000 position and. 396 00:21:54,000 --> 00:21:56,000 Can grub ledge equals true. 397 00:21:56,000 --> 00:21:58,000 Let's go back to Unity now. 398 00:21:59,000 --> 00:22:00,000 Begin to select player. 399 00:22:00,000 --> 00:22:03,000 Find animation of the ledge climb. 400 00:22:05,000 --> 00:22:09,000 Go to the last frame or maybe even one after. 401 00:22:09,000 --> 00:22:12,000 Click add event and find ledge. 402 00:22:12,000 --> 00:22:14,000 Climb over. 403 00:22:22,000 --> 00:22:24,000 This might cause a little bug. 404 00:22:24,000 --> 00:22:26,000 And I'm going to show you how to fix it, if it will. 405 00:22:28,000 --> 00:22:28,000 Yeah. 406 00:22:28,000 --> 00:22:30,000 So now it works perfectly. 407 00:22:30,000 --> 00:22:33,000 And now there was a bug you see, in that it was triggered twice. 408 00:22:33,000 --> 00:22:34,000 So what happens here? 409 00:22:34,000 --> 00:22:41,000 We set in our can grab latch to true at the moment when player is still is attached to the ledge and 410 00:22:41,000 --> 00:22:44,000 he detected ledge again and he's doing all the process again. 411 00:22:44,000 --> 00:22:47,000 So what we need here is to make a short delay. 412 00:22:47,000 --> 00:22:53,000 How we can do that We can create a function private void, allow ledge grab. 413 00:22:53,000 --> 00:22:58,000 It's going to return only one line of code so we don't necessarily have to type curly brackets. 414 00:22:58,000 --> 00:23:03,000 We can just put return sign, which is combination of equals and bigger. 415 00:23:03,000 --> 00:23:09,000 So this means return and it will say return can grab ledge equals true. 416 00:23:10,000 --> 00:23:15,000 Now we're going to go back to a ledge, climb over and instead of this line of code, we're going to 417 00:23:15,000 --> 00:23:15,000 type. 418 00:23:17,000 --> 00:23:20,000 Invoke and invoke means you can call function with the delay. 419 00:23:20,000 --> 00:23:24,000 Just how it says here invokes method name in time seconds. 420 00:23:24,000 --> 00:23:28,000 So in the parentheses we're going to put quotation marks. 421 00:23:28,000 --> 00:23:31,000 We need a name of the function and it should be exact name. 422 00:23:31,000 --> 00:23:37,000 So let's copy it here, paste it in here, and then put comma point one F Now it should be fine. 423 00:23:37,000 --> 00:23:38,000 Let's go back. 424 00:23:42,000 --> 00:23:42,000 And. 425 00:23:46,000 --> 00:23:47,000 Works perfectly. 426 00:23:49,000 --> 00:23:52,000 Now there might be some issue just like what I showed you. 427 00:23:52,000 --> 00:23:55,000 But I know this because I faced this before. 428 00:23:55,000 --> 00:24:01,000 Look, if I'm jumping from here, he's not detecting ledge, but he's supposed to right from here. 429 00:24:01,000 --> 00:24:06,000 He does detect in a ledge, but from above he does not. 430 00:24:06,000 --> 00:24:07,000 So what happens here? 431 00:24:07,000 --> 00:24:10,000 Sometimes there is no enough time to make detection. 432 00:24:10,000 --> 00:24:11,000 Right. 433 00:24:12,000 --> 00:24:13,000 Let me show it to you. 434 00:24:17,000 --> 00:24:18,000 All right, So. 435 00:24:22,000 --> 00:24:28,000 So he's there and he's supposed to detect the ledge but rigid by they move so fast that there is no 436 00:24:28,000 --> 00:24:29,000 time to detect the ledge. 437 00:24:29,000 --> 00:24:34,000 What we can do here is we can take our ledge detection. 438 00:24:34,000 --> 00:24:37,000 And rigid body to it rooted by the two D. 439 00:24:38,000 --> 00:24:42,000 Then I'm going to open this rigid body and change body type to kinematic. 440 00:24:43,000 --> 00:24:45,000 Collision detection should be continuous. 441 00:24:46,000 --> 00:24:47,000 We can close this now. 442 00:24:48,000 --> 00:24:52,000 So this what will help us to detect collision even if we move in fast? 443 00:24:53,000 --> 00:24:53,000 Yeah. 444 00:24:53,000 --> 00:24:54,000 Continuous detection. 445 00:24:55,000 --> 00:24:57,000 Then we can cover it. 446 00:24:57,000 --> 00:25:03,000 And just in case, let's increase the box Collider of our trigger to the right side to something like 447 00:25:03,000 --> 00:25:04,000 this. 448 00:25:04,000 --> 00:25:06,000 You don't have to do precise copy. 449 00:25:06,000 --> 00:25:08,000 Just make it a bit bigger and longer. 450 00:25:08,000 --> 00:25:11,000 All right, Now we can check it again. 451 00:25:11,000 --> 00:25:12,000 Let me try that. 452 00:25:12,000 --> 00:25:19,000 Right now, it's okay detecting from any spot, but we can see that sometimes offset is really off and 453 00:25:19,000 --> 00:25:22,000 there is a bit of space between the player and the platform. 454 00:25:22,000 --> 00:25:27,000 We can fix that just by finding our check and. 455 00:25:28,000 --> 00:25:29,000 Decrease in the radius. 456 00:25:29,000 --> 00:25:33,000 So maybe, I don't know, like 1.5 to make it small. 457 00:25:33,000 --> 00:25:36,000 And now we need to adjust offset just by bit. 458 00:25:36,000 --> 00:25:37,000 I don't know. 459 00:25:37,000 --> 00:25:38,000 I'll try here. 460 00:25:38,000 --> 00:25:39,000 25. 461 00:25:39,000 --> 00:25:40,000 Not sure. 462 00:25:42,000 --> 00:25:43,000 Let me change to focused. 463 00:25:46,000 --> 00:25:46,000 Yeah. 464 00:25:46,000 --> 00:25:47,000 It looks like it's okay. 465 00:25:49,000 --> 00:25:50,000 Yeah, it's fine. 466 00:25:52,000 --> 00:25:55,000 If you still have a bit of offset, try to just adjust these values. 467 00:25:56,000 --> 00:25:59,000 And remember, first offset is for position before the climb. 468 00:25:59,000 --> 00:26:03,000 Second, offset for position after climb. 469 00:26:03,000 --> 00:26:06,000 Let's go and put some comments there so you won't forget it. 470 00:26:06,000 --> 00:26:08,000 Offset for position. 471 00:26:08,000 --> 00:26:10,000 Be for a climb. 472 00:26:10,000 --> 00:26:12,000 I'm going to copy this. 473 00:26:13,000 --> 00:26:14,000 Paste it in here. 474 00:26:14,000 --> 00:26:16,000 Offset for position. 475 00:26:18,000 --> 00:26:19,000 After a climb. 476 00:26:21,000 --> 00:26:22,000 Thank you for attention. 477 00:26:22,000 --> 00:26:24,000 I know it was a long video. 478 00:26:24,000 --> 00:26:26,000 I know it might be difficult. 479 00:26:26,000 --> 00:26:30,000 I remember myself when I did something like this, and it felt complicated. 480 00:26:30,000 --> 00:26:34,000 But I'm telling you, in no time you'll be creating your own video games. 481 00:26:34,000 --> 00:26:37,000 I'll see in the next video by.
