And there we go. 99 00:04:59,780 --> 00:05:02,030 So now you can see that this one also has 100 00:05:02,030 --> 00:05:05,770 its own level name and press the E key to open the door. 101 00:05:05,765 --> 00:05:08,825 So now what are we actually going to do? 102 00:05:08,825 --> 00:05:11,345 We want to get the level name, 103 00:05:11,345 --> 00:05:14,315 which should be a string and this plate right here. 104 00:05:14,315 --> 00:05:15,725 But as you remember. 105 00:05:15,724 --> 00:05:17,064 The level of exit, 106 00:05:17,060 --> 00:05:18,730 where is it an exit? 107 00:05:18,725 --> 00:05:20,785 We change this to an integer. 108 00:05:20,780 --> 00:05:22,880 So how are we actually 109 00:05:22,880 --> 00:05:25,780 going to do this in here and start? 110 00:05:25,775 --> 00:05:28,025 I'm going to create the start. 111 00:05:28,025 --> 00:05:30,605 And now you need to focus a lot, 112 00:05:30,605 --> 00:05:32,125 but don't worry, everything will 113 00:05:32,120 --> 00:05:34,310 be slowly but surely explained. 114 00:05:34,310 --> 00:05:36,940 So first of all, I'm going to create a string 115 00:05:36,935 --> 00:05:40,355 variable which is going to be the scene path. 116 00:05:40,355 --> 00:05:46,505 And this path will be equal to seen utility. 117 00:05:46,505 --> 00:05:52,225 Seen utility, but obviously we cannot use it. 118 00:05:52,220 --> 00:05:57,650 So I'm going to add in here the senior management. 119 00:05:57,650 --> 00:06:02,090 And now we should have access to the scene utility. 120 00:06:02,090 --> 00:06:05,450 And then from the same utility I'm going to get seen 121 00:06:05,450 --> 00:06:09,140 path can see right here by the build index. 122 00:06:09,140 --> 00:06:12,010 So now I can add this right here, 123 00:06:12,005 --> 00:06:15,355 and I can say the level to load. 124 00:06:15,350 --> 00:06:16,870 Save that. 125 00:06:16,865 --> 00:06:18,725 So what will this give us? 126 00:06:18,725 --> 00:06:22,045 I'm just going to go ahead and print this out in here. 127 00:06:22,040 --> 00:06:28,470 So I will say print out the scene path. 128 00:06:29,020 --> 00:06:37,850 And let's just seen path concatenated. Save that. 129 00:06:37,850 --> 00:06:39,380 And before I move on, 130 00:06:39,380 --> 00:06:40,730 there is something that we 131 00:06:40,730 --> 00:06:42,730 probably should have done and that is 132 00:06:42,725 --> 00:06:46,945 actually using the level exit one and level exit to two, 133 00:06:46,940 --> 00:06:48,890 assigned the level to go. 134 00:06:48,890 --> 00:06:55,650 So level manager and where are the level exits? 135 00:06:56,200 --> 00:06:58,220 Waves? 136 00:06:58,220 --> 00:07:00,970 We have spawns 0, 137 00:07:00,965 --> 00:07:02,755 so they aren't in here. 138 00:07:02,750 --> 00:07:06,150 And I'm going to select the portals. 139 00:07:06,154 --> 00:07:08,764 So portal has this one. 140 00:07:08,765 --> 00:07:10,705 So which one has the first portal? 141 00:07:10,700 --> 00:07:13,160 This one and the second portal will 142 00:07:13,160 --> 00:07:16,540 be the second one on the level manager. 143 00:07:16,535 --> 00:07:19,075 So there we go, we save that. 144 00:07:19,070 --> 00:07:22,160 So now we have access to both the portals. 145 00:07:22,160 --> 00:07:25,360 And now we can go back in here, 146 00:07:25,355 --> 00:07:27,785 slide down and the level manager. 147 00:07:27,785 --> 00:07:30,395 And after we get the level of exit, 148 00:07:30,395 --> 00:07:33,475 one dot on the level exit, 149 00:07:33,470 --> 00:07:35,480 we can either assign it immediately, 150 00:07:35,480 --> 00:07:36,830 call this public, or we can 151 00:07:36,830 --> 00:07:38,660 create a small method in here, 152 00:07:38,660 --> 00:07:44,240 which we'll say that it's a public void. 153 00:07:44,240 --> 00:07:52,220 And we'll make it set the level to load. 154 00:07:52,220 --> 00:07:59,810 And this will be the level two load. 155 00:07:59,810 --> 00:08:03,460 Or let's just make it level. 156 00:08:03,455 --> 00:08:05,195 So shortcut it. 157 00:08:05,195 --> 00:08:08,155 And in here we're just going to say that the level 158 00:08:08,150 --> 00:08:11,960 to low level looped. 159 00:08:11,960 --> 00:08:14,750 Save that back in 160 00:08:14,750 --> 00:08:19,430 the level manager that set level to load. 161 00:08:19,430 --> 00:08:22,370 And it's going to be the level 1. 162 00:08:22,370 --> 00:08:25,010 And then in here we're going to set 163 00:08:25,010 --> 00:08:34,060 the level x2 dot set level to low level to go to two. 164 00:08:34,055 --> 00:08:35,465 Excellent. 165 00:08:35,465 --> 00:08:37,595 So now we should have 166 00:08:37,595 --> 00:08:41,665 this level to load being except right here. 167 00:08:41,660 --> 00:08:44,330 And I'm just going to show you what 168 00:08:44,330 --> 00:08:46,790 we are going to get displayed on the screen. 169 00:08:46,790 --> 00:08:49,440 So when we run the game, 170 00:08:49,660 --> 00:08:52,310 we should see right here in 171 00:08:52,310 --> 00:08:54,320 the console, Let's pause that. 172 00:08:54,320 --> 00:08:56,380 And the console we shall see 173 00:08:56,375 --> 00:09:00,205 the scene path asset scenes style screen. 174 00:09:00,200 --> 00:09:03,740 So obviously, this is the path that we 175 00:09:03,740 --> 00:09:07,360 are getting sent and this is the current level to load. 176 00:09:07,355 --> 00:09:09,425 And what does the current level that we're on? 177 00:09:09,425 --> 00:09:11,465 It's currently being set as 0. 178 00:09:11,465 --> 00:09:15,385 So 0, if we look in the settings in here, 179 00:09:15,380 --> 00:09:18,010 you can see that 0 is the title screen, 180 00:09:18,005 --> 00:09:21,385 so you can see how the scene path was being displayed. 181 00:09:21,380 --> 00:09:25,100 So our goal is to remove everything and just keep 182 00:09:25,100 --> 00:09:27,770 the title screen and have it being 183 00:09:27,770 --> 00:09:30,890 displayed right here under the door name. 184 00:09:30,890 --> 00:09:32,750 So that's what we're going to do. 185 00:09:32,750 --> 00:09:33,950 If I go back in here, 186 00:09:33,950 --> 00:09:35,600 let's remove the print. 187 00:09:35,600 --> 00:09:37,840 And now this is the scary part. 188 00:09:37,835 --> 00:09:41,725 I'm going to say that the integer is 189 00:09:41,720 --> 00:09:45,860 the last slash and it's 190 00:09:45,860 --> 00:09:51,540 equal to the scene path dot last index of. 191 00:09:52,600 --> 00:09:55,190 And use this forward slash. 192 00:09:55,190 --> 00:09:58,240 Actually it's between a single quotation. 193 00:09:58,235 --> 00:10:00,175 So what happens in here? 194 00:10:00,170 --> 00:10:05,570 Let's again print and, or know what. 195 00:10:05,570 --> 00:10:06,710 Let's continue on and you'll 196 00:10:06,710 --> 00:10:09,200 understand easily what that means. 197 00:10:09,200 --> 00:10:12,140 So string name and 198 00:10:12,140 --> 00:10:15,110 it's going to be equal to the same path 199 00:10:15,110 --> 00:10:25,980 substring last slash and plus 1, 0 plus 1. 200 00:10:26,290 --> 00:10:30,880 And let's try to print the name and see what we get. 201 00:10:30,875 --> 00:10:34,705 So you can see the last index substring, 202 00:10:34,700 --> 00:10:36,890 and then we are going to run this 203 00:10:36,890 --> 00:10:39,400 again so we can see what's happening. 204 00:10:39,395 --> 00:10:41,935 So we run the game 205 00:10:41,930 --> 00:10:46,180 and we can see that we have right now the title screen. 206 00:10:46,175 --> 00:10:47,935 So what is going on in here? 207 00:10:47,930 --> 00:10:50,390 First of all, let's talk about the substring. 208 00:10:50,389 --> 00:10:52,819 Let me just show you what that is. 209 00:10:52,820 --> 00:10:54,680 Okay, so in here you can see 210 00:10:54,680 --> 00:10:57,080 the string dot substring method and 211 00:10:57,080 --> 00:11:00,500 definition and retrieves a substring from this instance. 212 00:11:00,500 --> 00:11:03,100 And you can see we can use an int 32, 213 00:11:03,095 --> 00:11:06,455 retrieves a substring, which will obviously a string. 214 00:11:06,455 --> 00:11:08,185 Then we have a substring. 215 00:11:08,180 --> 00:11:11,570 Substring starts at a specific character position 216 00:11:11,570 --> 00:11:13,910 and continues to the end of that string. 217 00:11:13,910 --> 00:11:16,040 So this is what's happening in here. 218 00:11:16,040 --> 00:11:18,340 We are getting the last index 219 00:11:18,335 --> 00:11:21,365 where we have this forward slash. 220 00:11:21,365 --> 00:11:23,915 And then we are using a substring of that. 221 00:11:23,915 --> 00:11:26,945 So remember how previously that would be displayed. 222 00:11:26,945 --> 00:11:29,485 I'm going to print out 223 00:11:29,480 --> 00:11:32,890 the scene path in here 224 00:11:32,885 --> 00:11:34,885 again so you can clearly 225 00:11:34,880 --> 00:11:36,740 see how the all of that is working. 226 00:11:36,740 --> 00:11:38,600 Well, I'm taking my time to explain 227 00:11:38,600 --> 00:11:40,990 everything because this is a bit confusing. 228 00:11:40,985 --> 00:11:43,955 So on the console there we go, Assets, scenes, 229 00:11:43,955 --> 00:11:45,835 and the last index where we have 230 00:11:45,830 --> 00:11:48,890 this forward slash and then a title screen. 231 00:11:48,890 --> 00:11:51,050 We have the last index, 232 00:11:51,050 --> 00:11:53,000 which is the integer right here. 233 00:11:53,000 --> 00:11:55,420 And then the name is a substring which 234 00:11:55,415 --> 00:11:59,035 starts at the last slash plus one. 235 00:11:59,030 --> 00:12:01,190 So we start immediately after 236 00:12:01,190 --> 00:12:04,900 the visit right here after the last slash. 237 00:12:04,895 --> 00:12:07,915 Now the final step is to remove also the dot. 238 00:12:07,910 --> 00:12:09,440 So I'm going to do that. 239 00:12:09,440 --> 00:12:13,720 And in here I'm going to say that int dot 240 00:12:13,715 --> 00:12:19,835 is equal to name dot last index of. 241 00:12:19,835 --> 00:12:24,095 And then I'm going to use the little dot. 242 00:12:24,095 --> 00:12:27,145 And then finally I'm going to print out. 243 00:12:27,140 --> 00:12:29,240 And probably you should do 244 00:12:29,240 --> 00:12:31,160 this now that you know how everything is done. 245 00:12:31,160 --> 00:12:33,910 Name dot substring. 246 00:12:33,905 --> 00:12:38,725 And where is it between 0 and the dot. 247 00:12:38,720 --> 00:12:42,080 And this is also another form of the substring. 248 00:12:42,080 --> 00:12:43,460 You can see it right here, 249 00:12:43,460 --> 00:12:46,040 a substring and 32 and 32. 250 00:12:46,040 --> 00:12:47,810 So when we give it two parameters, 251 00:12:47,810 --> 00:12:51,410 it retrieves a substring from this instance starts at 252 00:12:51,410 --> 00:12:53,450 a specified character position and 253 00:12:53,450 --> 00:12:55,990 has a specified length. 254 00:12:55,985 --> 00:12:58,055 I'm going to go back in here. 255 00:12:58,055 --> 00:12:59,635 I'm going to save all of 256 00:12:59,630 --> 00:13:02,240 that and I'm going to run the game. 257 00:13:02,240 --> 00:13:04,940 And they now run the game. 258 00:13:04,940 --> 00:13:07,970 And you'll see in the console that we have, 259 00:13:07,970 --> 00:13:10,180 first of all, we had the whole path, 260 00:13:10,175 --> 00:13:11,485 then we reduced it. 261 00:13:11,480 --> 00:13:15,200 And finally we have access to the title screen. 262 00:13:15,200 --> 00:13:16,460 So as you can see, 263 00:13:16,460 --> 00:13:20,480 this is very powerful and I will admit a bit complicated, 264 00:13:20,480 --> 00:13:23,130 but this is the only way to actually do it for 265 00:13:23,130 --> 00:13:24,650 actually the only way that I know 266 00:13:24,650 --> 00:13:26,290 maybe there is another way, 267 00:13:26,285 --> 00:13:29,705 but for now, it's time for a challenge. 268 00:13:29,705 --> 00:13:31,375 And your challenge is to set 269 00:13:31,370 --> 00:13:34,100 the text in a new script so make 270 00:13:34,100 --> 00:13:36,560 the text appear and disappear if the player 271 00:13:36,560 --> 00:13:39,470 is in a certain area next to the door, 272 00:13:39,470 --> 00:13:42,800 get a new script and attach it to the UI object. 273 00:13:42,800 --> 00:13:45,740 So obviously, you'll need to create a new script added 274 00:13:45,740 --> 00:13:49,120 to the UI elements or UI canvas, 275 00:13:49,115 --> 00:13:51,005 or maybe even the door if you want, 276 00:13:51,005 --> 00:13:53,885 immediately added to the door, 277 00:13:53,885 --> 00:13:56,065 use the entrepreneur enter and 278 00:13:56,060 --> 00:13:58,730 exit similar to the shop items, 279 00:13:58,730 --> 00:14:02,300 use the E key to open the doors and make 280 00:14:02,300 --> 00:14:06,080 sure we can't see the canvas when we start the game. 281 00:14:06,080 --> 00:14:08,380 So that information, pause the video right 282 00:14:08,375 --> 00:14:12,035 now and go do VJ alone. 283 00:14:12,040 --> 00:14:14,480 Okay, welcome back. 284 00:14:14,480 --> 00:14:17,090 So this video is getting too long. 285 00:14:17,090 --> 00:14:21,050 We are already about over 15 minutes into it, 286 00:14:21,050 --> 00:14:23,900 and I don't want to make this a huge video, 287 00:14:23,900 --> 00:14:25,780 so I'm going to cut it right now. 288 00:14:25,775 --> 00:14:27,125 I hope you did the challenge. 289 00:14:27,125 --> 00:14:30,175 In the next video, we will continue on with everything. 290 00:14:30,170 --> 00:14:32,290 I hope you enjoy it. I'll see you in the next one. 291 00:14:32,285 --> 00:14:35,125 Don't for the first time ever don't commit 292 00:14:35,120 --> 00:14:36,560 your changes because we will 293 00:14:36,560 --> 00:14:38,810 be doing a lot of things and the next one. 294 00:14:38,810 --> 00:14:41,010 So see you then.
