1 00:00:00,000 --> 00:00:03,360 Welcome back my fellow game developers 2 00:00:03,360 --> 00:00:04,950 to a brand new video. 3 00:00:04,950 --> 00:00:06,720 And in this one, as you can see, 4 00:00:06,720 --> 00:00:10,910 we've created a little flying freaking demon, 5 00:00:10,905 --> 00:00:14,825 but this time he is not a very brave. 6 00:00:14,820 --> 00:00:16,080 He is a bit cowardly, 7 00:00:16,080 --> 00:00:18,630 so he starts running away when we get close. 8 00:00:18,630 --> 00:00:20,360 So now I walk around, 9 00:00:20,355 --> 00:00:21,755 I get close and as you can see, 10 00:00:21,750 --> 00:00:25,170 he starts running away and throwing his poop at us, 11 00:00:25,170 --> 00:00:27,470 I think, or dirt or I don't know what that is. 12 00:00:27,465 --> 00:00:29,615 So as you can see, we tried to shoot him. 13 00:00:29,610 --> 00:00:32,040 We tried to get close, obviously his stock by the wall, 14 00:00:32,040 --> 00:00:33,320 but you can see that when we 15 00:00:33,320 --> 00:00:35,170 approach from a different direction, 16 00:00:35,165 --> 00:00:36,515 still his stock on the wall, 17 00:00:36,515 --> 00:00:37,855 but no worries about that. 18 00:00:37,850 --> 00:00:40,250 You see that he is running away from us. 19 00:00:40,250 --> 00:00:44,650 So let's not waste any more time and let's get started. 20 00:00:44,645 --> 00:00:47,755 Okay, so as you can see, 21 00:00:47,750 --> 00:00:50,510 I've created for more enemies, 22 00:00:50,510 --> 00:00:53,410 the cowardly flying, I, 23 00:00:53,405 --> 00:00:55,765 the goblin wonder one. 24 00:00:55,760 --> 00:00:58,300 I don't know why it's called Wonder one, 25 00:00:58,295 --> 00:01:00,055 but anyways, that's his name. 26 00:01:00,050 --> 00:01:01,940 And of course we have the skeleton and 27 00:01:01,940 --> 00:01:04,490 finally we have the patrolling mushroom. 28 00:01:04,490 --> 00:01:06,370 So we are going to be using 29 00:01:06,365 --> 00:01:08,185 all of these in every single video. 30 00:01:08,180 --> 00:01:09,920 And as I've said, I don't want to go 31 00:01:09,920 --> 00:01:12,070 through the process of doing this with you. 32 00:01:12,065 --> 00:01:15,085 All I did is I just duplicated the skeleton, 33 00:01:15,080 --> 00:01:17,290 change the body sprite, 34 00:01:17,285 --> 00:01:20,885 change the animator, the animation and all of that. 35 00:01:20,885 --> 00:01:22,915 I also made sure to change and here 36 00:01:22,910 --> 00:01:25,420 the animation and so on and so forth. 37 00:01:25,415 --> 00:01:28,415 So now they all chases and do the same. 38 00:01:28,415 --> 00:01:30,535 But what we're going to do is we're going to 39 00:01:30,530 --> 00:01:33,140 remove the cowardly or the goblin Wanderer, 40 00:01:33,140 --> 00:01:36,590 the patrolling mushroom, and the skeleton enemy. 41 00:01:36,590 --> 00:01:40,240 And we're just going to keep the cowardly flying I, 42 00:01:40,235 --> 00:01:44,045 and this is what we'll use to create our cowardly enemy. 43 00:01:44,045 --> 00:01:46,195 So without any further ado, 44 00:01:46,190 --> 00:01:48,500 let's go ahead and open up the control. 45 00:01:48,500 --> 00:01:50,500 Oh, and by the way, I've also created 46 00:01:50,495 --> 00:01:52,955 a projectile for each one of those. 47 00:01:52,955 --> 00:01:55,355 So each one has his own projectile. 48 00:01:55,355 --> 00:01:56,555 I've created that too. 49 00:01:56,555 --> 00:01:58,685 But anyways, and let's 50 00:01:58,685 --> 00:02:01,295 open up the enemy controller in here. 51 00:02:01,295 --> 00:02:04,145 And let's get started with a couple of goats. 52 00:02:04,145 --> 00:02:07,315 So the first thing that we need is we need to go up 53 00:02:07,310 --> 00:02:12,460 here and we'll need to add a bit of space. 54 00:02:12,455 --> 00:02:15,745 And we're going to say that these are the enemies that 55 00:02:15,740 --> 00:02:21,680 runaway and it means that run away. 56 00:02:21,680 --> 00:02:23,690 And in here I'm going to create 57 00:02:23,690 --> 00:02:26,080 two serialized fields which are going to be 58 00:02:26,075 --> 00:02:31,405 a Boolean for the should run away. 59 00:02:31,400 --> 00:02:34,220 And then another serialized field for 60 00:02:34,220 --> 00:02:38,740 the float run away range. 61 00:02:38,735 --> 00:02:42,005 So R1 way range. 62 00:02:42,005 --> 00:02:44,455 And obviously because we want to have 63 00:02:44,450 --> 00:02:46,060 a certain range at which 64 00:02:46,055 --> 00:02:48,635 the enemy will start running away. 65 00:02:48,635 --> 00:02:51,335 Now, there is another thing that we need to add 66 00:02:51,335 --> 00:02:54,235 because we are creating enemies that should run away. 67 00:02:54,230 --> 00:02:55,280 We also should know 68 00:02:55,280 --> 00:02:57,670 the enemies that should be chasing the player. 69 00:02:57,665 --> 00:03:00,905 So I'm going to again create another one in here, 70 00:03:00,905 --> 00:03:02,795 which is going to be the, 71 00:03:02,795 --> 00:03:06,335 or know what up here we've created something. 72 00:03:06,335 --> 00:03:08,545 And he made the attacker within the news that 73 00:03:08,540 --> 00:03:11,900 yet player move direction, 74 00:03:11,900 --> 00:03:14,300 player to chase player chase range. 75 00:03:14,300 --> 00:03:16,220 Okay, so in here I'm going to create 76 00:03:16,220 --> 00:03:19,790 this and have the enemies that chess player, 77 00:03:19,790 --> 00:03:23,980 enemies that chase the layer. 78 00:03:23,975 --> 00:03:26,365 And in here I'm also going to create 79 00:03:26,360 --> 00:03:29,180 a serialized field for the Boolean. 80 00:03:29,179 --> 00:03:35,469 There's going to be the should chase player. 81 00:03:35,465 --> 00:03:37,105 There we go. So now we have 82 00:03:37,100 --> 00:03:39,320 the option to choose one of these two. 83 00:03:39,320 --> 00:03:42,940 And let's see what we need to do before we continue on. 84 00:03:42,935 --> 00:03:46,065 We need to add this should chase player condition. 85 00:03:46,069 --> 00:03:47,539 So where do we add it? 86 00:03:47,540 --> 00:03:49,470 First of all, we need to add it obviously 87 00:03:49,474 --> 00:03:52,974 in when we are giving velocity. 88 00:03:52,970 --> 00:03:55,010 So in here we update 89 00:03:55,010 --> 00:03:58,310 looking animating enemy moving towards the player. 90 00:03:58,310 --> 00:04:00,670 So there we go, moving towards the player. 91 00:04:00,665 --> 00:04:03,685 And here we need to make sure that we are also 92 00:04:03,680 --> 00:04:08,420 having and we should chase the player. 93 00:04:08,420 --> 00:04:11,420 So in here we get the direction which is the player 94 00:04:11,420 --> 00:04:12,770 to chase position minus 95 00:04:12,770 --> 00:04:14,690 the current position of the enemy. 96 00:04:14,690 --> 00:04:17,570 And then we go there and we said the is chasing. 97 00:04:17,570 --> 00:04:19,070 And in here as you can see, 98 00:04:19,070 --> 00:04:20,990 I have redundant code. 99 00:04:20,990 --> 00:04:23,290 These two lines are exactly the same. 100 00:04:23,285 --> 00:04:25,195 So what I'm going to do is I'm 101 00:04:25,190 --> 00:04:27,160 going to create a variable in here, 102 00:04:27,155 --> 00:04:28,765 which is going to be called, 103 00:04:28,760 --> 00:04:32,080 so distance is a float. 104 00:04:32,075 --> 00:04:35,405 So we're going to create a float, 105 00:04:35,405 --> 00:04:38,875 which is going to be the distance, 106 00:04:38,870 --> 00:04:43,040 distance player, enemy. 107 00:04:43,040 --> 00:04:47,890 And it's going to be equal to the vector distance, 108 00:04:47,885 --> 00:04:49,685 et cetera, et cetera. 109 00:04:49,685 --> 00:04:51,845 And instead of this long line, 110 00:04:51,845 --> 00:04:55,975 I'm going to say that it's the distance layer enemy. 111 00:04:55,970 --> 00:04:58,280 Add a bit of space. 112 00:04:58,280 --> 00:05:01,630 There we go. And now double-click in here, 113 00:05:01,625 --> 00:05:04,255 copy that, paste it in here it's the same, right? 114 00:05:04,250 --> 00:05:06,170 So transform position, player 115 00:05:06,170 --> 00:05:08,410 chase dot position, exactly the same. 116 00:05:08,405 --> 00:05:09,295 There we go. 117 00:05:09,290 --> 00:05:10,330 We save that. 118 00:05:10,325 --> 00:05:13,075 And also in here we need to make sure that he is 119 00:05:13,070 --> 00:05:18,650 chasing and is the should chase player. 120 00:05:18,650 --> 00:05:20,950 There we go, save that. 121 00:05:20,945 --> 00:05:22,135 And with that done, 122 00:05:22,130 --> 00:05:24,460 let's continue on and see what we have. 123 00:05:24,455 --> 00:05:25,925 Now in here. 124 00:05:25,925 --> 00:05:27,865 We already know what happens 125 00:05:27,860 --> 00:05:29,840 if we should be chasing the player. 126 00:05:29,840 --> 00:05:31,430 But what happens if we should 127 00:05:31,430 --> 00:05:33,220 be running away from the player? 128 00:05:33,215 --> 00:05:36,425 I'm going to create a separate if condition in here, 129 00:05:36,425 --> 00:05:38,365 which is going to say. 130 00:05:38,360 --> 00:05:43,640 If we should be running away or we should run away. 131 00:05:43,640 --> 00:05:47,800 And where does it end the distance?
