There we go. 244 00:12:20,030 --> 00:12:21,170 So as you can see, 245 00:12:21,170 --> 00:12:23,690 his health gets smaller and he gets 246 00:12:23,690 --> 00:12:27,200 angry right about the halfway point of our game. 247 00:12:27,200 --> 00:12:31,030 Finally, when we shoot them for the last time, he dies. 248 00:12:31,025 --> 00:12:33,155 But we still have this health bark. 249 00:12:33,155 --> 00:12:34,495 And not only that, we have 250 00:12:34,490 --> 00:12:36,560 this small error appearing in here, 251 00:12:36,560 --> 00:12:40,070 well actually not a small error, a constant error. 252 00:12:40,070 --> 00:12:41,630 So I'm going to collapse it. 253 00:12:41,630 --> 00:12:44,780 Double-click in here and see what the problem is. 254 00:12:44,780 --> 00:12:46,730 Find objects of type. 255 00:12:46,730 --> 00:12:48,710 So this is a null reference. 256 00:12:48,709 --> 00:12:50,239 Null reference means that we are 257 00:12:50,240 --> 00:12:51,950 trying to get a reference to 258 00:12:51,950 --> 00:12:56,000 something that does not exist or the return is not. 259 00:12:56,000 --> 00:12:59,230 So in here we have the boss health handler. 260 00:12:59,225 --> 00:13:01,135 And obviously when we die, 261 00:13:01,130 --> 00:13:02,870 we destroy the boss. 262 00:13:02,870 --> 00:13:04,400 And when we destroy the boss, 263 00:13:04,400 --> 00:13:06,740 the boss health handler goals William. 264 00:13:06,740 --> 00:13:10,330 So we need to find a solution to that, 265 00:13:10,325 --> 00:13:12,905 and that is going to be your challenge. 266 00:13:12,905 --> 00:13:14,605 Your challenge is to remove 267 00:13:14,600 --> 00:13:17,770 the Health Bar and make the boss invincible. 268 00:13:17,765 --> 00:13:20,765 Maybe your challenge isn't to fix the error. 269 00:13:20,765 --> 00:13:23,005 Anyways, let's see what we have in here. 270 00:13:23,000 --> 00:13:24,950 First of all, when the boss dies, 271 00:13:24,950 --> 00:13:26,480 make sure that the health bar is 272 00:13:26,480 --> 00:13:28,430 removed and stop the error. 273 00:13:28,430 --> 00:13:30,560 You'll need to obviously remove 274 00:13:30,560 --> 00:13:33,560 the Health Bar and remove the image and the picture. 275 00:13:33,560 --> 00:13:35,210 So we don't no longer have to 276 00:13:35,210 --> 00:13:36,830 call that every single time. 277 00:13:36,830 --> 00:13:39,290 Then you'll need to make sure that when 278 00:13:39,290 --> 00:13:42,080 the bus is going into the angry state, 279 00:13:42,080 --> 00:13:44,330 we want to make him invincible. 280 00:13:44,330 --> 00:13:46,250 So when he is getting angry, 281 00:13:46,250 --> 00:13:48,320 we don't want to be able to shoot him. 282 00:13:48,320 --> 00:13:49,610 This is first of all, not 283 00:13:49,610 --> 00:13:51,140 fair to the boss because he cannot 284 00:13:51,140 --> 00:13:54,200 attack us or move when he is getting angry. 285 00:13:54,200 --> 00:13:56,630 Second of all, because in every single game 286 00:13:56,630 --> 00:13:59,420 when a boss transitions into the second phase, 287 00:13:59,420 --> 00:14:00,890 you cannot hit him. 288 00:14:00,890 --> 00:14:03,350 This is something standard and all games. 289 00:14:03,350 --> 00:14:05,030 So I'm going to give you a hint 290 00:14:05,030 --> 00:14:06,800 of how to do the last part. 291 00:14:06,800 --> 00:14:10,610 You'll need to add behavior to the get anger state. 292 00:14:10,610 --> 00:14:11,990 And as I told you, 293 00:14:11,990 --> 00:14:14,150 we need to fix the problem of the error. 294 00:14:14,150 --> 00:14:18,770 While obviously when we actually disable the half bark 295 00:14:18,770 --> 00:14:20,570 at no longer calls for 296 00:14:20,570 --> 00:14:23,600 the players held the bosses health handler, 297 00:14:23,600 --> 00:14:25,480 so we no longer have the arrow. 298 00:14:25,475 --> 00:14:27,245 So with that information, 299 00:14:27,245 --> 00:14:31,505 pause the video right now and go do the challenge. 300 00:14:31,505 --> 00:14:34,255 So, okay, welcome back. 301 00:14:34,250 --> 00:14:36,890 So the first thing that we're going to do 302 00:14:36,890 --> 00:14:41,210 is we're going to go into the update and here. 303 00:14:41,210 --> 00:14:44,000 And we're going to check if 304 00:14:44,000 --> 00:14:49,100 the boss health slider dot value 305 00:14:49,100 --> 00:14:53,040 is less than or equal to 0, 306 00:14:53,040 --> 00:14:55,270 that means that we are going to 307 00:14:55,270 --> 00:14:59,260 destroy the entire game object. 308 00:14:59,260 --> 00:15:01,900 Now we, we don't have to destroy the game object. 309 00:15:01,900 --> 00:15:04,960 We can maybe set the game object to active, 310 00:15:04,960 --> 00:15:07,800 false, or set it to inactive. 311 00:15:07,795 --> 00:15:10,005 But I'm just going to destroy it just 312 00:15:10,000 --> 00:15:12,280 so we make sure we don't have anything anymore. 313 00:15:12,280 --> 00:15:13,750 So save that. 314 00:15:13,750 --> 00:15:17,380 And then we are going to go into the boss health handler. 315 00:15:17,380 --> 00:15:20,170 And in here we are going to create a variable. 316 00:15:20,170 --> 00:15:21,990 And that variable is going to be 317 00:15:21,985 --> 00:15:29,545 a public bool and is in invincible. 318 00:15:29,544 --> 00:15:31,844 And it's going to be set 319 00:15:31,840 --> 00:15:33,820 to false at the beginning or you know what? 320 00:15:33,820 --> 00:15:35,390 Let's not make it public. 321 00:15:35,385 --> 00:15:37,735 Let's make it a private. 322 00:15:37,730 --> 00:15:39,680 And we'll create a method in 323 00:15:39,680 --> 00:15:41,860 here that is going to be public, 324 00:15:41,855 --> 00:15:44,875 int or no, Actually, sorry, void. 325 00:15:44,870 --> 00:15:46,030 Set. 326 00:15:46,025 --> 00:15:48,745 The boss. 327 00:15:48,740 --> 00:15:51,970 Even subtle. 328 00:15:51,965 --> 00:15:55,805 And it's going to take in a parameter which is a Boolean. 329 00:15:55,805 --> 00:16:01,165 And it's going to be is 330 00:16:01,160 --> 00:16:05,410 Skelly or normal not 331 00:16:05,405 --> 00:16:13,055 that is boss in a given symbol. 332 00:16:13,055 --> 00:16:17,495 And then in here we are going to say that is invincible 333 00:16:17,495 --> 00:16:22,385 is equal to, is boss invincible. 334 00:16:22,385 --> 00:16:23,635 Save that. 335 00:16:23,630 --> 00:16:26,720 And in here, before we take damage, as you can see, 336 00:16:26,720 --> 00:16:28,810 we have the comment if getting angry, 337 00:16:28,805 --> 00:16:30,065 this should not work. 338 00:16:30,065 --> 00:16:35,035 So we're going to say, if is invincible, 339 00:16:35,030 --> 00:16:38,050 then we are going to help, 340 00:16:38,045 --> 00:16:41,555 then we are going to just return. 341 00:16:41,555 --> 00:16:43,825 So return means. 342 00:16:43,820 --> 00:16:45,610 When we do return, 343 00:16:45,605 --> 00:16:47,575 just like we have the return values 344 00:16:47,570 --> 00:16:49,300 and here once we get to the return, 345 00:16:49,295 --> 00:16:51,055 this entire method stops. 346 00:16:51,050 --> 00:16:53,420 So anything under this line of code. 347 00:16:53,420 --> 00:16:55,400 So in here, anything that we write will 348 00:16:55,400 --> 00:16:57,860 not be registered after the return. 349 00:16:57,860 --> 00:17:00,080 And this is exactly what we do in here. 350 00:17:00,080 --> 00:17:02,420 So when we take damage in here, 351 00:17:02,420 --> 00:17:04,630 we check if he is invincible. 352 00:17:04,625 --> 00:17:06,875 We open this one up. 353 00:17:06,875 --> 00:17:07,805 Sorry. 354 00:17:07,805 --> 00:17:10,405 We enter into the condition, 355 00:17:10,400 --> 00:17:12,250 we execute the return and none 356 00:17:12,245 --> 00:17:14,365 of these lines get executed. 357 00:17:14,360 --> 00:17:16,880 So we basically return a value, 358 00:17:16,880 --> 00:17:18,340 and because this is a void, 359 00:17:18,335 --> 00:17:19,805 we can return anything. 360 00:17:19,805 --> 00:17:21,425 If it was an integer, 361 00:17:21,425 --> 00:17:24,995 not a void, we could just return 0. 362 00:17:24,995 --> 00:17:27,335 So I'm going to remove this. 363 00:17:27,335 --> 00:17:28,945 I'm going to save all of this. 364 00:17:28,940 --> 00:17:31,190 And now how are we actually going to 365 00:17:31,190 --> 00:17:33,560 be setting the is invincible? 366 00:17:33,560 --> 00:17:35,600 I'm going to go back in here. 367 00:17:35,600 --> 00:17:37,940 I had this one running. 368 00:17:37,940 --> 00:17:40,250 And let's this out. 369 00:17:40,250 --> 00:17:42,230 First of all, the Health Bar. 370 00:17:42,230 --> 00:17:45,670 So Shruti, should the Shruti. 371 00:17:45,665 --> 00:17:47,395 Surely, there we go. 372 00:17:47,390 --> 00:17:49,990 And when he finishes this animation, he will die. 373 00:17:49,985 --> 00:17:51,865 And you can see that we no longer have 374 00:17:51,860 --> 00:17:55,010 a health bar and we no longer have any errors. 375 00:17:55,010 --> 00:17:55,730 Excellent. 376 00:17:55,730 --> 00:17:58,370 Now the next thing to do is to go into 377 00:17:58,370 --> 00:18:02,170 the animator and to the getting angry state. 378 00:18:02,165 --> 00:18:04,525 And why is this not becoming smaller? 379 00:18:04,520 --> 00:18:05,540 Okay, so in the end, 380 00:18:05,540 --> 00:18:08,270 get angry, we're going to add a behavior. 381 00:18:08,270 --> 00:18:15,960 We're going to call it the boss, underscore, get angry. 382 00:18:15,964 --> 00:18:20,104 New script, create an ad. 383 00:18:20,105 --> 00:18:25,085 And obviously it will be created in the assets in here, 384 00:18:25,085 --> 00:18:26,615 the boss get angry. 385 00:18:26,615 --> 00:18:28,645 I'm going to move it into 386 00:18:28,640 --> 00:18:32,040 the scripts Boss folder 387 00:18:32,044 --> 00:18:34,854 for file or whatever you wanna call it. 388 00:18:34,850 --> 00:18:37,580 So was, there we go. 389 00:18:37,580 --> 00:18:39,710 So both get angry. 390 00:18:39,710 --> 00:18:41,050 Open this one up. 391 00:18:41,045 --> 00:18:44,005 As we can see, the last two we will not need. 392 00:18:44,000 --> 00:18:50,220 And these ones will be control KU. 393 00:18:52,360 --> 00:18:57,130 Control key, you can control KU. 394 00:18:57,125 --> 00:18:59,315 So in here, what should we be doing? 395 00:18:59,315 --> 00:19:01,465 Where should we be making sure that 396 00:19:01,460 --> 00:19:04,060 the boss is invincible or setting it up? 397 00:19:04,055 --> 00:19:06,565 Well, I believe we should first of all, 398 00:19:06,560 --> 00:19:09,710 set it to true when we enter into the state. 399 00:19:09,710 --> 00:19:15,450 So I'm going to access the animator component. 400 00:19:15,580 --> 00:19:20,390 So now we have access to the boss health handler. 401 00:19:20,390 --> 00:19:22,700 And in here we are going to set 402 00:19:22,700 --> 00:19:26,300 the boss invincibility to true. 403 00:19:26,300 --> 00:19:28,780 And then when we exit, 404 00:19:28,775 --> 00:19:33,875 I'm going to duplicate this line and move it down. 405 00:19:33,875 --> 00:19:36,005 And when we exit the state, 406 00:19:36,005 --> 00:19:38,465 then we again can get hit. 407 00:19:38,465 --> 00:19:40,375 So as you can see, 408 00:19:40,370 --> 00:19:45,070 right here, we've created the set boss invincible. 409 00:19:45,065 --> 00:19:48,005 We have a parameter that we need to send it. 410 00:19:48,005 --> 00:19:49,615 We access it using 411 00:19:49,610 --> 00:19:51,850 the component of the boss health handler, 412 00:19:51,845 --> 00:19:55,195 which is also present with the animator. 413 00:19:55,190 --> 00:19:58,160 So we have both components on the same game object. 414 00:19:58,160 --> 00:20:00,160 That's why we can access the animator, 415 00:20:00,155 --> 00:20:01,825 get a component which is 416 00:20:01,820 --> 00:20:04,990 the half Handler said the boss invincibility to true. 417 00:20:04,985 --> 00:20:07,255 And in here, when we said is 418 00:20:07,250 --> 00:20:10,040 invincible to whatever the boss, 419 00:20:10,040 --> 00:20:11,980 invincible whatever the parameter. 420 00:20:11,975 --> 00:20:14,125 If it is true, then it returns. 421 00:20:14,120 --> 00:20:16,450 If it's false, then we do not return. 422 00:20:16,445 --> 00:20:17,675 The boss takes damage. 423 00:20:17,675 --> 00:20:18,605 We save that. 424 00:20:18,605 --> 00:20:20,065 We go back into our game. 425 00:20:20,060 --> 00:20:22,130 Who were. 426 00:20:22,130 --> 00:20:25,240 So up here, we run the game. 427 00:20:25,235 --> 00:20:28,895 We should the bus once, twice. 428 00:20:28,895 --> 00:20:32,525 And you can see right here that while he is angry, 429 00:20:32,525 --> 00:20:33,685 he does not get damaged. 430 00:20:33,680 --> 00:20:35,800 So I've shot him three to four times. 431 00:20:35,795 --> 00:20:37,085 He does not get damaged. 432 00:20:37,085 --> 00:20:39,235 Finally, I shoot him, he dies. 433 00:20:39,230 --> 00:20:40,730 And there we go. 434 00:20:40,730 --> 00:20:43,430 We'd have no errors except for this one which is I 435 00:20:43,430 --> 00:20:46,820 believe something that isn't any of our concern, 436 00:20:46,820 --> 00:20:48,890 something about the panel. 437 00:20:48,890 --> 00:20:50,650 We have this OK time. 438 00:20:50,645 --> 00:20:52,505 So we're going to go out, 439 00:20:52,505 --> 00:20:56,725 we're going to make sure to stage all of our files and 440 00:20:56,720 --> 00:21:02,150 now created a health bar. 441 00:21:02,150 --> 00:21:03,490 So I hope you enjoyed, 442 00:21:03,485 --> 00:21:05,275 excuse me for the long video, 443 00:21:05,270 --> 00:21:08,270 but this is what happens when we are creating UI. 444 00:21:08,270 --> 00:21:10,280 This is all based on your preference, 445 00:21:10,280 --> 00:21:11,750 how you want your game to look. 446 00:21:11,750 --> 00:21:13,970 And I'll see you in the next video. 447 00:21:13,970 --> 00:21:16,700 And I believe the final video where we will make 448 00:21:16,700 --> 00:21:20,300 the boss actually shoot after a certain amount of time. 449 00:21:20,300 --> 00:21:22,470 So see you then.
