1 00:00:00,000 --> 00:00:03,690 Welcome back, My favorite game developers. 2 00:00:03,690 --> 00:00:06,540 In this video, we are going to be creating 3 00:00:06,540 --> 00:00:11,180 our first script and adding it to our doom player. 4 00:00:11,175 --> 00:00:14,675 Not only that, we are going to be learning a lot of things, 5 00:00:14,670 --> 00:00:17,970 we are going to be learning what this scary word means. 6 00:00:17,970 --> 00:00:19,710 We're going to learn about variables. 7 00:00:19,710 --> 00:00:21,210 We're going to learn about inputs. 8 00:00:21,210 --> 00:00:23,070 We're going to learn about vector 2. 9 00:00:23,070 --> 00:00:26,910 We are going to be learning how start and update work separately. 10 00:00:26,910 --> 00:00:28,760 So with that said, 11 00:00:28,755 --> 00:00:31,265 this is a bit of a longer video if you want, 12 00:00:31,260 --> 00:00:33,510 but if you're a beginner, it's very important, 13 00:00:33,510 --> 00:00:36,350 very crucial to understand everything. 14 00:00:36,345 --> 00:00:41,245 So let's not waste any more time and let's get started. 15 00:00:41,245 --> 00:00:45,785 Oh, okay, so time for some scripting. 16 00:00:45,785 --> 00:00:49,075 The first thing we're going to do is we're going to create 17 00:00:49,070 --> 00:00:53,120 a script and assign it to the doom player. 18 00:00:53,120 --> 00:00:56,570 Now, there are many ways of creating scripts and there 19 00:00:56,570 --> 00:01:00,010 are many ways of assigning scripts to certain objects. 20 00:01:00,005 --> 00:01:01,405 They are all the same. 21 00:01:01,400 --> 00:01:04,040 Let's start off with the most basic one, 22 00:01:04,040 --> 00:01:07,550 and that is simply clicking on the game object. 23 00:01:07,550 --> 00:01:10,280 You can see right here that we have the transform. 24 00:01:10,280 --> 00:01:12,950 It is one of the components that we have. 25 00:01:12,950 --> 00:01:17,450 We can add another component right here by clicking on it. 26 00:01:17,450 --> 00:01:21,740 Now, you can see that we have many components that we can add, 27 00:01:21,740 --> 00:01:24,040 ranging from audio to affect, 28 00:01:24,035 --> 00:01:25,775 to physics and so on. 29 00:01:25,775 --> 00:01:30,755 But we also have this option right here of adding scripts. 30 00:01:30,755 --> 00:01:35,455 We can click on it. We can see through it and add whichever script that we want. 31 00:01:35,450 --> 00:01:37,250 Or even easier than that, 32 00:01:37,250 --> 00:01:41,980 we can simply start typing in the name of the script that we want to add. 33 00:01:41,975 --> 00:01:47,095 And the script that we want to call or create will be the player controller. 34 00:01:47,090 --> 00:01:52,210 So we're going to create layer controller right here and make 35 00:01:52,210 --> 00:01:58,060 sure that you create the name to be a single sentence without any spaces. 36 00:01:58,060 --> 00:02:01,420 You can see right here we have the option for a new script. 37 00:02:01,420 --> 00:02:02,470 Let's click on it. 38 00:02:02,470 --> 00:02:05,880 You can see the name as player controller. 39 00:02:05,875 --> 00:02:08,175 And now we can create the script, 40 00:02:08,170 --> 00:02:13,060 but make sure that shoe figure out correct word or the correct 41 00:02:13,060 --> 00:02:18,220 name for the script because it will be the name of the class inside of this script. 42 00:02:18,220 --> 00:02:22,110 This will be very crucial as you create scripts later on. 43 00:02:22,105 --> 00:02:24,675 So we're going to create an ad. 44 00:02:24,670 --> 00:02:27,970 Wait for just a little bit. 45 00:02:27,970 --> 00:02:32,810 And now we should see that we have the script ready. 46 00:02:32,810 --> 00:02:34,250 If we click on it right here, 47 00:02:34,250 --> 00:02:38,330 we can see in the Inspector what this script will look like. 48 00:02:38,330 --> 00:02:41,180 And now we are going to double-click. 49 00:02:41,180 --> 00:02:44,770 And you can see that Visual Studio is opening up. 50 00:02:44,765 --> 00:02:45,185 Now. 51 00:02:45,185 --> 00:02:51,025 One of the things many people or many students of mine keep asking me over and over. 52 00:02:51,020 --> 00:02:55,850 If your script doesn't open up using Visual Studio, or for example, 53 00:02:55,850 --> 00:03:01,420 when you type something in here and you don't get the recommendations by Visual Studio, 54 00:03:01,415 --> 00:03:07,355 you can go into the that, go to Preferences, 55 00:03:07,355 --> 00:03:10,025 go to the External Tools, 56 00:03:10,025 --> 00:03:12,355 and in the external script editor, 57 00:03:12,350 --> 00:03:15,640 make sure that you have Visual Studio Community. 58 00:03:15,635 --> 00:03:19,385 You can choose our IDEs like Visual Studio Code. 59 00:03:19,385 --> 00:03:26,105 But me personally, I like or prefer to use the Visual Studio Community 2019. 60 00:03:26,105 --> 00:03:28,765 It's much better and smoother than the studio. 61 00:03:28,760 --> 00:03:32,620 Sometimes studio just has its quirks where it doesn't show up, 62 00:03:32,615 --> 00:03:33,985 doesn't open up correctly. 63 00:03:33,980 --> 00:03:37,540 So I prefer using Visual Studio Community. 64 00:03:37,535 --> 00:03:38,305 That's free. 65 00:03:38,300 --> 00:03:39,040 It works. 66 00:03:39,035 --> 00:03:40,225 Let's continue on. 67 00:03:40,220 --> 00:03:40,850 Now. 68 00:03:40,850 --> 00:03:43,930 We have our script opened up right here. 69 00:03:43,925 --> 00:03:47,845 We have the libraries that we can use. 70 00:03:47,840 --> 00:03:51,100 We have the class name, the player controller. 71 00:03:51,095 --> 00:03:56,435 It should always have the same name as the script that we've created right here. 72 00:03:56,435 --> 00:04:00,985 So you can see player controller under no circumstances do you 73 00:04:00,980 --> 00:04:06,400 change the name of the script in here without changing the class name? 74 00:04:06,395 --> 00:04:08,155 Don't even try to do that. 75 00:04:08,150 --> 00:04:10,850 It will create a lot of problems. 76 00:04:10,849 --> 00:04:12,969 What do we have here? It's a public, 77 00:04:12,965 --> 00:04:14,305 we'll see what that means. 78 00:04:14,300 --> 00:04:17,320 It's a class, it's mono behavior. 79 00:04:17,315 --> 00:04:23,555 Monte behavior gives us the ability to use things such as start and update. 80 00:04:23,555 --> 00:04:26,765 What is start? Start is a method. 81 00:04:26,765 --> 00:04:28,885 We'll see later on what methods are. 82 00:04:28,880 --> 00:04:32,780 But for now all you need to know any code that we write inside of 83 00:04:32,780 --> 00:04:38,600 the star gets executed as soon as we start our game, 84 00:04:38,600 --> 00:04:40,640 if that object is turned on, 85 00:04:40,640 --> 00:04:43,690 of course, we'll see what that also means later on. 86 00:04:43,685 --> 00:04:45,215 An update, as you can see, 87 00:04:45,215 --> 00:04:47,455 update is called once per frame. 88 00:04:47,450 --> 00:04:49,990 So if we have, for example, 89 00:04:49,985 --> 00:04:54,625 things that we want to call every single frame update is perfect 90 00:04:54,620 --> 00:04:58,940 for that and we will see all of this as we progress through this course. 91 00:04:58,940 --> 00:05:01,430 You'll understand everything, don't worry about it. 92 00:05:01,430 --> 00:05:07,700 Now, the first thing we need to do is we need a way to move our player. 93 00:05:07,700 --> 00:05:13,790 We will do that by taking inputs from the arrow keys or the WASD keys. 94 00:05:13,790 --> 00:05:15,430 But before we do that, 95 00:05:15,425 --> 00:05:18,815 there is something that we need to take into consideration and that 96 00:05:18,815 --> 00:05:22,405 is the movement speed of our player. 97 00:05:22,400 --> 00:05:26,120 And for that, we are going to need a variable. 98 00:05:26,120 --> 00:05:30,890 What is a variable when it comes to C-sharp? Let me explain. 99 00:05:30,890 --> 00:05:34,010 Variables are like boxes. 100 00:05:34,010 --> 00:05:36,070 So we have a box, 101 00:05:36,065 --> 00:05:38,665 we give it the name lives, 102 00:05:38,660 --> 00:05:42,650 and we put inside that box a number three. 103 00:05:42,650 --> 00:05:49,600 So now we have a variable obtain lives that has a three inside of it. 104 00:05:49,595 --> 00:05:55,535 So this is how we create the code for this box or valuable. 105 00:05:55,535 --> 00:05:58,675 We start off by giving the accessibility. 106 00:05:58,670 --> 00:06:01,580 So where can you access this variable? 107 00:06:01,580 --> 00:06:04,790 Can either be public or it can be private. 108 00:06:04,790 --> 00:06:08,060 If it's private, we can only access it inside 109 00:06:08,060 --> 00:06:11,470 of the class we've created, not from outside. 110 00:06:11,465 --> 00:06:16,165 If it's public, we can exit from any other script that we want. 111 00:06:16,160 --> 00:06:18,850 We need to assign the type of the variable. 112 00:06:18,845 --> 00:06:20,545 So we have multiple types, 113 00:06:20,540 --> 00:06:22,970 we have integers, strings and so on. 114 00:06:22,970 --> 00:06:26,420 We will see in just a bit what other types we have. 115 00:06:26,420 --> 00:06:28,390 We have the name of the variable. 116 00:06:28,385 --> 00:06:30,805 Obviously, every variable should have a name. 117 00:06:30,800 --> 00:06:32,240 How else do we call it? 118 00:06:32,240 --> 00:06:36,550 And we have the data that is inside of this variable. 119 00:06:36,545 --> 00:06:40,495 So this is how we create a variable in C Sharp. 120 00:06:40,490 --> 00:06:42,590 And this is the representation if you want, 121 00:06:42,590 --> 00:06:47,830 It's just like a box that we put things and then we move on. 122 00:06:47,825 --> 00:06:50,935 We have different types of variables. 123 00:06:50,930 --> 00:06:53,600 And the first type is a velocity. 124 00:06:53,600 --> 00:06:58,580 So an integer is a normal number, let's say 123456. 125 00:06:58,580 --> 00:07:02,450 A float is, let's say 4.8. 126 00:07:02,450 --> 00:07:03,880 Why do we have a float? 127 00:07:03,875 --> 00:07:10,655 Because sometimes the speed of something or the velocity of a car isn't just five or six. 128 00:07:10,655 --> 00:07:13,195 It can be 6.32, 129 00:07:13,190 --> 00:07:17,710 it can be 6.9, it can be 6.9456. 130 00:07:17,705 --> 00:07:19,685 So we need a float, 131 00:07:19,685 --> 00:07:21,625 and this is how we create a float. 132 00:07:21,620 --> 00:07:23,690 We always add the data. 133 00:07:23,690 --> 00:07:27,400 So the 4.8 with an F on the end. 134 00:07:27,395 --> 00:07:29,785 Then we have a Boolean. 135 00:07:29,780 --> 00:07:34,310 The Boolean is usually either true or it's false. 136 00:07:34,310 --> 00:07:39,710 So for example, let's say we want to determine whether a player is dead or not. 137 00:07:39,710 --> 00:07:42,130 So as he, that he is dead, 138 00:07:42,125 --> 00:07:44,015 then the variable is true. 139 00:07:44,015 --> 00:07:45,425 If he's not dead, 140 00:07:45,425 --> 00:07:48,335 then the variable is that S false. 141 00:07:48,335 --> 00:07:50,035 Finally, we have a string. 142 00:07:50,030 --> 00:07:54,500 So for example, what is a string of characters? 143 00:07:54,500 --> 00:07:56,120 We have multiple characters, 144 00:07:56,120 --> 00:07:57,410 one after the other. 145 00:07:57,410 --> 00:08:00,020 I see h, e, l. 146 00:08:00,020 --> 00:08:04,290 That string of characters is Michael. 147 00:08:04,294 --> 00:08:09,484 So we call a variable of type string with the name my name, 148 00:08:09,485 --> 00:08:11,365 and it represents michael. 149 00:08:11,360 --> 00:08:17,440 Make sure whenever you create a string variable that is between these two quotes. 150 00:08:17,435 --> 00:08:20,705 Okay, now, with all these variables done with, 151 00:08:20,705 --> 00:08:25,175 Let's go ahead and create our own variable in the scripts right here. 152 00:08:25,175 --> 00:08:27,635 So the first thing we're going to do, 153 00:08:27,635 --> 00:08:32,635 as we are going to create something called a serialized field. 154 00:08:32,630 --> 00:08:36,290 Now, don't be scared of this long name. 155 00:08:36,290 --> 00:08:38,200 It's going to be an integer, 156 00:08:38,195 --> 00:08:41,735 and it's going to be called the movement speed. 157 00:08:41,735 --> 00:08:46,615 Now this will determined how fast our player moves as we 158 00:08:46,610 --> 00:08:51,880 implemented your understand and why are we using something called the serialized field. 159 00:08:51,875 --> 00:08:53,425 You just told me, Michael, 160 00:08:53,420 --> 00:08:55,580 that it's either public or private. 161 00:08:55,580 --> 00:08:58,430 What does this serialized field Meet? 162 00:08:58,430 --> 00:09:00,580 Well, don't worry about it. 163 00:09:00,575 --> 00:09:01,415 Later on. 164 00:09:01,415 --> 00:09:05,995 I will also explain why we are using something called a serialized field. 165 00:09:05,990 --> 00:09:11,950 But for now understand that it is something that we can see in the Inspector. 166 00:09:11,945 --> 00:09:14,255 So if I make this public, 167 00:09:14,255 --> 00:09:18,295 save this, go back into our script. 168 00:09:18,290 --> 00:09:21,740 You'll see that in the inspector this changes. 169 00:09:21,740 --> 00:09:23,390 We have the public and movement. 170 00:09:23,390 --> 00:09:24,890 And if we go to the doom player, 171 00:09:24,890 --> 00:09:29,170 you can see right here that we have the movement speed and we can change it. 172 00:09:29,165 --> 00:09:34,915 But if I make it private so that other scripts don't access it, 173 00:09:34,910 --> 00:09:39,970 you'll notice right here that we no longer can change it. 174 00:09:39,965 --> 00:09:44,665 But what if we want to be able to change it from the Inspector, 175 00:09:44,660 --> 00:09:46,450 but at the same time, 176 00:09:46,445 --> 00:09:49,445 we don't want other scripts to access it. 177 00:09:49,445 --> 00:09:51,035 Well, in that case, 178 00:09:51,035 --> 00:09:54,665 we create a serialized field. 179 00:09:54,665 --> 00:09:55,775 We save that. 180 00:09:55,775 --> 00:09:57,325 We go back and do inspector. 181 00:09:57,320 --> 00:09:58,750 And you can see right now, 182 00:09:58,745 --> 00:10:00,605 we can't change it, 183 00:10:00,605 --> 00:10:03,385 but other scripts cannot access it. 184 00:10:03,380 --> 00:10:08,870 We'll look into that later on as we progress when we have other scripts. 185 00:10:08,869 --> 00:10:14,139 Great, so now we have the variable of the movement speed. 186 00:10:14,135 --> 00:10:16,655 The next thing we want to get is d, 187 00:10:16,655 --> 00:10:21,145 movement, direction or the input that we get. 188 00:10:21,140 --> 00:10:24,320 So how are we going to move our player? 189 00:10:24,320 --> 00:10:27,530 Well, we are going to need two inputs. 190 00:10:27,530 --> 00:10:31,460 One which will move the player left and right, 191 00:10:31,460 --> 00:10:33,530 or in the horizontal direction, 192 00:10:33,530 --> 00:10:36,710 and one which will move the player up and down, 193 00:10:36,710 --> 00:10:39,460 which is the vertical direction. 194 00:10:39,455 --> 00:10:44,995 So the way we do that is by using the input system and we're going to 195 00:10:44,990 --> 00:10:50,800 get our inputs using something called the input dot get access Raw. 196 00:10:50,795 --> 00:10:53,375 Now, you might be confused.
