1 00:00:00,200 --> 00:00:04,740 Welcome back my fellow game developers to a brand new video. 2 00:00:04,740 --> 00:00:06,000 And in this video, 3 00:00:06,000 --> 00:00:07,590 when we run our game, 4 00:00:07,590 --> 00:00:09,380 when we click on the enemy, 5 00:00:09,375 --> 00:00:12,515 you'll notice that he has an extra variable in here, 6 00:00:12,510 --> 00:00:16,140 which is the enemy health and phi shoot him with a couple of bullets. 7 00:00:16,140 --> 00:00:20,510 Notice how his health deteriorates from 100 to 40. 8 00:00:20,505 --> 00:00:28,895 And if I keep shooting him from 40 to 0 and he disappears because he is dead. 9 00:00:28,890 --> 00:00:32,310 So we are going to learn a lot of things in this video. 10 00:00:32,310 --> 00:00:36,780 Put your thinking caps on and let's get started. 11 00:00:36,775 --> 00:00:44,345 Oh, okay, So now time to start damaging our enemies using method. 12 00:00:44,345 --> 00:00:48,775 So first thing we're going to do is we're going to create a way 13 00:00:48,770 --> 00:00:53,650 to add health or to remove health from our enemy. 14 00:00:53,645 --> 00:00:56,815 So I'm going to go into the enemy controller. 15 00:00:56,810 --> 00:01:00,200 And here, Let's open up Visual Studio. 16 00:01:00,200 --> 00:01:06,530 And I'm going to create an integer variable that will represent the health of the enemy. 17 00:01:06,530 --> 00:01:08,030 Why is it an integer? 18 00:01:08,030 --> 00:01:10,010 Well, because we want to keep things simple. 19 00:01:10,010 --> 00:01:11,990 We don't want it to be a float. 20 00:01:11,990 --> 00:01:15,380 So I'm going to add it right here under the speed. 21 00:01:15,380 --> 00:01:20,110 So we're going to create a serialized field which will be of type integer. 22 00:01:20,105 --> 00:01:22,385 And it's going to be called the Health. 23 00:01:22,385 --> 00:01:25,315 And I'm going to set it to be 100 at the beginning, 24 00:01:25,310 --> 00:01:28,780 so we never have the Health at 0. 25 00:01:28,775 --> 00:01:32,885 I'm going to look back into inspector and see how that looks. 26 00:01:32,885 --> 00:01:36,445 And they now, okay, great. 27 00:01:36,440 --> 00:01:42,670 So now you can see that I have the option in here to change the health of our enemy. 28 00:01:42,665 --> 00:01:47,995 Now, how are we going to make sure that every time the enemy gets hit, 29 00:01:47,990 --> 00:01:50,720 we remove a bill of health. 30 00:01:50,720 --> 00:01:55,130 We are going to create a method to do that. What are methods? 31 00:01:55,130 --> 00:01:57,910 Well, you've already seen me create methods. 32 00:01:57,905 --> 00:01:59,725 The update is a method. 33 00:01:59,720 --> 00:02:05,380 We start as a method and also the gizmo select as a method. 34 00:02:05,375 --> 00:02:12,725 But let's delve a bit deeper into the actual structure of a method and see how we use it. 35 00:02:12,725 --> 00:02:15,175 So let me put my laser on, 36 00:02:15,170 --> 00:02:17,530 and this is the method structure. 37 00:02:17,525 --> 00:02:23,875 So it's similar to the way we create variables in that it has an accessibility. 38 00:02:23,870 --> 00:02:26,200 So an access type, what is it? 39 00:02:26,195 --> 00:02:28,315 Is it a private, a public? 40 00:02:28,310 --> 00:02:30,590 We can't make it a serialized field, 41 00:02:30,590 --> 00:02:33,110 but we can create either a public, 42 00:02:33,110 --> 00:02:37,940 which means that we can access this method from anywhere in our scripts, 43 00:02:37,940 --> 00:02:39,160 in any other scripts. 44 00:02:39,155 --> 00:02:45,475 If it's private, we can only access it inside of the class where we are using. 45 00:02:45,470 --> 00:02:47,870 Then we have the return type. 46 00:02:47,870 --> 00:02:50,830 For example, void returns, nothing. 47 00:02:50,825 --> 00:02:52,475 What is a return type? 48 00:02:52,475 --> 00:02:53,935 As we move through the course, 49 00:02:53,930 --> 00:02:56,570 you'll understand all the different return types. 50 00:02:56,570 --> 00:03:01,960 But what this means is that we can actually return a value from this method. 51 00:03:01,955 --> 00:03:03,635 If it doesn't return anything, 52 00:03:03,635 --> 00:03:05,345 that means it's void. 53 00:03:05,345 --> 00:03:08,015 So for example, let me show you in here. 54 00:03:08,015 --> 00:03:11,245 This is a void because we don't return any value. 55 00:03:11,240 --> 00:03:14,660 We don't expect any value to be given back 56 00:03:14,660 --> 00:03:18,980 from this method later on when we do have a method that returns something, 57 00:03:18,980 --> 00:03:21,580 may, I will make sure to point that out for you. 58 00:03:21,575 --> 00:03:24,425 Next, we have the method name. 59 00:03:24,425 --> 00:03:27,055 So usually whenever you want to name a method, 60 00:03:27,050 --> 00:03:30,580 you have to name it by what this method actually does. 61 00:03:30,575 --> 00:03:34,805 And you can notice how we create the name of a method. 62 00:03:34,805 --> 00:03:41,605 It, unlike the variables were the first word has to always be in the lower class, 63 00:03:41,600 --> 00:03:45,530 or the first letter of the first word has to be lower class. 64 00:03:45,530 --> 00:03:47,410 In a method name, 65 00:03:47,405 --> 00:03:51,425 all the words inside of the method name have to be capitalized. 66 00:03:51,425 --> 00:03:53,855 So you can see that adding velocity, 67 00:03:53,855 --> 00:03:56,065 so this method is a private, 68 00:03:56,060 --> 00:03:58,550 so we only use it in a class void. 69 00:03:58,550 --> 00:04:02,210 It doesn't return anything and its name is adding velocity. 70 00:04:02,210 --> 00:04:06,020 That means it adds velocity to some kinds of objects. 71 00:04:06,020 --> 00:04:08,770 And what are the parentheses on the end? 72 00:04:08,765 --> 00:04:11,215 While these are called the parameter, 73 00:04:11,210 --> 00:04:16,300 parameter means that we can send a certain value to that method. 74 00:04:16,295 --> 00:04:21,575 And it can use it in order to do calculations or anything that it wants. 75 00:04:21,575 --> 00:04:28,285 We will demonstrate how this all works in the method which will damage our enemies. 76 00:04:28,280 --> 00:04:31,010 So enough talking, let's get started. 77 00:04:31,010 --> 00:04:34,000 I'm going to open up Visual Studio and here, 78 00:04:33,995 --> 00:04:37,885 and I'm going to create a method inside of the enemy controller. 79 00:04:37,880 --> 00:04:40,850 I will scroll down on the Earth, the update. 80 00:04:40,850 --> 00:04:44,560 And in here I will create a method to damage the enemy. 81 00:04:44,555 --> 00:04:47,035 First thing first, what do I need it to be? 82 00:04:47,030 --> 00:04:48,680 Does it have to be a private? 83 00:04:48,680 --> 00:04:52,210 So I can only use it inside of here and the enemy controller, 84 00:04:52,205 --> 00:04:54,425 or does it have to be a public? 85 00:04:54,425 --> 00:04:56,965 That means I can access it from anywhere. 86 00:04:56,960 --> 00:05:00,860 Well, most probably I will need it to be public because 87 00:05:00,860 --> 00:05:04,820 I want the bullets damage the enemy whenever they hit the enemy. 88 00:05:04,820 --> 00:05:08,200 What's going to be a public void, 89 00:05:08,195 --> 00:05:12,155 and I'm going to call it the damage enemy. 90 00:05:12,155 --> 00:05:17,405 And it's a void because we don't need to return anything from the damage enemy. 91 00:05:17,405 --> 00:05:21,695 All we need to do is remove a bit of health that we already have. 92 00:05:21,695 --> 00:05:23,915 And here, so the enemy health. 93 00:05:23,915 --> 00:05:26,245 And let's change this or no, 94 00:05:26,240 --> 00:05:29,150 I'm going to show you a very cool trick and just stay bit. 95 00:05:29,150 --> 00:05:32,260 Anyways, let's continue on with our main focus. 96 00:05:32,255 --> 00:05:36,415 I also want to send them a parameter of type integer, 97 00:05:36,410 --> 00:05:38,630 which is going to be the damage. 98 00:05:38,630 --> 00:05:39,760 They can. 99 00:05:39,755 --> 00:05:47,095 So now what I can do is I can access the health and I can remove from it. 100 00:05:47,090 --> 00:05:50,480 Sorry, the damage taken. 101 00:05:50,480 --> 00:05:52,680 So now what happens? 102 00:05:52,684 --> 00:05:56,274 You already know what the minus sign means. 103 00:05:56,270 --> 00:06:01,250 That means that we remove from the health the damage taken. 104 00:06:01,250 --> 00:06:11,150 And finally, we need to make sure that if the health is less than or equal to 0. 105 00:06:11,150 --> 00:06:14,600 That means you just add a bit of spaces in here. 106 00:06:14,600 --> 00:06:22,340 That means that our enemy has died and I want to destroy the game object. 107 00:06:22,340 --> 00:06:26,350 Okay, So let's look at another time at this. 108 00:06:26,345 --> 00:06:30,805 And before we do that, I think that the name health of a variable isn't that specific. 109 00:06:30,800 --> 00:06:34,130 I think we need to change it to enemies health. 110 00:06:34,130 --> 00:06:35,530 So what can I do in here? 111 00:06:35,525 --> 00:06:37,855 I can change the name in here to enemy health. 112 00:06:37,850 --> 00:06:42,560 Okay, and then scroll down here and change these two right here. 113 00:06:42,560 --> 00:06:44,650 But this is a bit cumbersome, 114 00:06:44,645 --> 00:06:49,085 especially if we have used health maybe 10 times in our code. 115 00:06:49,085 --> 00:06:50,945 So how can we avoid this? 116 00:06:50,945 --> 00:06:52,735 Simply double-click on health, 117 00:06:52,730 --> 00:06:54,850 click Control R, R. 118 00:06:54,845 --> 00:06:57,395 And now you'll see that you can add this. 119 00:06:57,395 --> 00:07:00,365 So I'm going to call this the enemy health. 120 00:07:00,365 --> 00:07:02,165 I'm going to hit Enter. 121 00:07:02,165 --> 00:07:03,755 And if I scroll down, 122 00:07:03,755 --> 00:07:06,895 you'll see that enemy health has changed. 123 00:07:06,890 --> 00:07:08,480 So as a reminder, 124 00:07:08,480 --> 00:07:12,310 control or our click it two times, 125 00:07:12,305 --> 00:07:13,975 hold down Control R. 126 00:07:13,970 --> 00:07:18,920 And you'll be able to change the variable name and change it everywhere and the game. 127 00:07:18,920 --> 00:07:23,360 Now, the next thing we're going to do is we're going to actually call this method. 128 00:07:23,360 --> 00:07:25,000 And where do we call it from? 129 00:07:24,995 --> 00:07:27,775 We need to go to the bullet controller. 130 00:07:27,770 --> 00:07:32,920 And let me just find the bullet controller in here somewhere. 131 00:07:32,915 --> 00:07:34,715 Where is it in the scripts? 132 00:07:34,715 --> 00:07:38,605 In the bullets, in the law terrible at controller. 133 00:07:38,600 --> 00:07:42,980 And in here when we trigger something so we hit an object, 134 00:07:42,980 --> 00:07:44,320 what we're going to do, 135 00:07:44,315 --> 00:07:48,605 we're going to let me just remove this line from here. 136 00:07:48,605 --> 00:07:54,605 So we instantiate the impact and we're going to go ahead and access the collision. 137 00:07:54,605 --> 00:07:56,395 So what is the collision right here? 138 00:07:56,390 --> 00:08:02,140 As you can see, this is a parameter that is being sent to the method on Trigger Enter. 139 00:08:02,135 --> 00:08:06,695 What is the collision? It's the object that we've just collided with. 140 00:08:06,695 --> 00:08:08,635 So for example, if we hit a wall, 141 00:08:08,630 --> 00:08:10,850 the collision would be the wall that we've hit. 142 00:08:10,850 --> 00:08:11,960 And in our case, 143 00:08:11,960 --> 00:08:14,720 the collision will be the enemy that we've hit. 144 00:08:14,720 --> 00:08:18,880 And I'm going to get the component, excuse me. 145 00:08:18,875 --> 00:08:21,775 So I'm going to get the component which is on 146 00:08:21,770 --> 00:08:25,850 this collision and it's going to be the enemy controller. 147 00:08:25,850 --> 00:08:27,830 And in the enemy controller, 148 00:08:27,830 --> 00:08:30,760 because I've made this method in here public, 149 00:08:30,755 --> 00:08:32,395 I can access it right here, 150 00:08:32,390 --> 00:08:34,610 which is the damage and amine. 151 00:08:34,610 --> 00:08:39,380 And what should I send to this damage enemy? 152 00:08:39,380 --> 00:08:41,200 You can see right now, here, 153 00:08:41,195 --> 00:08:42,385 there is no arguments, 154 00:08:42,380 --> 00:08:44,450 so we need to give the damage taken. 155 00:08:44,450 --> 00:08:46,490 You'll notice all of this right here. 156 00:08:46,490 --> 00:08:51,130 So I'm going to send to it the damage amount. 157 00:08:51,125 --> 00:08:53,785 But we haven't created a damage amount. 158 00:08:53,780 --> 00:08:56,260 So let's go ahead and create it in here. 159 00:08:56,255 --> 00:09:02,425 So the bullet will also have a variable which will be an integer. 160 00:09:02,420 --> 00:09:05,390 And that will just copy this, 161 00:09:05,390 --> 00:09:10,750 which is going to be the damage amount and I'm going to set it to around 10. 162 00:09:10,745 --> 00:09:13,075 So what's happening in here? 163 00:09:13,070 --> 00:09:16,720 Every time the bullet collides with something, 164 00:09:16,715 --> 00:09:19,655 we get the information of that collision. 165 00:09:19,655 --> 00:09:21,185 We get the collision, 166 00:09:21,185 --> 00:09:23,795 we get the component of the enemy controller, 167 00:09:23,795 --> 00:09:26,725 and we access the damage enemy method there. 168 00:09:26,720 --> 00:09:28,850 We sent to it the damage amount. 169 00:09:28,850 --> 00:09:31,120 We go to the enemy controller. 170 00:09:31,115 --> 00:09:34,135 It's public, everything we get the enemy health, 171 00:09:34,130 --> 00:09:36,730 we remove the damaged taken. 172 00:09:36,725 --> 00:09:40,855 The damage taken as obviously the damage amount right here. 173 00:09:40,850 --> 00:09:45,110 And then we check if the health is less than or equal to 0. 174 00:09:45,110 --> 00:09:49,280 If it is, we destroy the game object because the enemy has done. 175 00:09:49,280 --> 00:09:52,040 So. Let's save all of that. 176 00:09:52,040 --> 00:09:54,710 And let's go ahead and test it out in Unity. 177 00:09:54,710 --> 00:09:57,410 So I'm going to click on the enemy, 178 00:09:57,410 --> 00:09:59,210 make sure that we see the enemy health. 179 00:09:59,210 --> 00:10:01,520 I'm going to run the code. 180 00:10:01,520 --> 00:10:04,610 I'm going to try to shoot our enemy. 181 00:10:04,610 --> 00:10:07,100 So I showed it until the bullets get third. 182 00:10:07,100 --> 00:10:08,720 Let's see enemy health. 183 00:10:08,720 --> 00:10:10,120 It was done. 184 00:10:10,115 --> 00:10:12,155 There you go.
