layer guns. 208 00:08:39,065 --> 00:08:41,545 So first of all, you need to create an entrepreneur 209 00:08:41,540 --> 00:08:44,050 Enter and check if we collided with a player. 210 00:08:44,045 --> 00:08:45,985 Obviously, we don't want our skeletons to 211 00:08:45,980 --> 00:08:48,230 be attacking us was shot guns. 212 00:08:48,230 --> 00:08:50,320 Who then you'll need to create 213 00:08:50,315 --> 00:08:52,375 a variable inside the method to 214 00:08:52,370 --> 00:08:54,290 keep track of whether we found 215 00:08:54,290 --> 00:08:56,600 the weapon or not on the player. 216 00:08:56,600 --> 00:08:59,230 You need to go through all the guns deep layer 217 00:08:59,225 --> 00:09:03,125 scurrying and obviously check if we're carrying the gun, 218 00:09:03,125 --> 00:09:05,815 you've picked up using the GAN name, 219 00:09:05,810 --> 00:09:08,320 so we'll need the gun name and phone to 220 00:09:08,315 --> 00:09:11,335 access the gun name and to access the available weapons, 221 00:09:11,330 --> 00:09:14,390 you'll need to create a couple of extra methods. 222 00:09:14,390 --> 00:09:16,000 So this is a big challenge, 223 00:09:15,995 --> 00:09:17,435 a very tough challenge, 224 00:09:17,435 --> 00:09:19,375 but I know you're up to the task. 225 00:09:19,370 --> 00:09:21,520 Take your time, play around, 226 00:09:21,515 --> 00:09:23,575 do mistakes, don't worry about it. 227 00:09:23,570 --> 00:09:26,020 I will be there to help you after we've tried. 228 00:09:26,015 --> 00:09:27,695 So you don't lose anything. 229 00:09:27,695 --> 00:09:32,345

about here, 238 00:09:55,460 --> 00:09:57,790 maybe we could have just immediately made 239 00:09:57,785 --> 00:10:01,285 all the pickups have a certain layer and make 240 00:10:01,280 --> 00:10:02,330 it only interact with 241 00:10:02,330 --> 00:10:04,690 the player layer that would have been a bit smart 242 00:10:04,685 --> 00:10:06,685 and maybe not have all of 243 00:10:06,680 -->
