- [x] roblox camera control to look around XD - [ ] whoa everything is so small , I was right my models were too big I'm gnz - [ ] - [ ] # day 2 unity jr programercourse Man the guy talks slowly, unit 1.1 important info your home view if you will. it centers your camera on the object that you have selected. god I love how smooooooooooooooothe these Phoenix switches are on my keyboard and wish I could just put them on my k3 but no ;-; the f key enables focus mode, this is like when u double click the middle mouse button in fusion to get to a decent reference frame for your object/file. it is primarily used to lock onto an object in space to move the camera and make it work - alt left click drag allows you to rotate your camera around the object that you have selected - alt right-click drag allows you to zoom but idk if I like using it but hay information is information I can't believe it's an 8-minute video explaining this to the user unit 1.1-4 in the transform component of an object you can select the menu button and click reset to reset the cords to all default apparently, in unity, it's commonly accepted knowledge that each unit is one metre. meaning yes my objects for my gnz project day 2/3 was indeed too big they also tell us that we can rename the object in the component's window or in the hierarchy window this happened on accident but you can maximize a screen by doing shift+space they also want us to name the obstacle of our choice obstacle a 3.5 min video saying ctrl+p starts/stops play mode and play mode does not save your game state if you click the arrows on the cube on the top right part of the scene thoe arrows will align your camera with the axis that you select. also the circular tool by the move or pan tool is for rotation the bottom one is for all types of transformation, scale rotation move uhhh the project folder area if you don't need to see the assets but just need to see file names/folder system the menu button for the project window has a 1 column layout for efficiency if you don't have the screen real estate for your desired view also on the top right you can click layout and change the layout by clicking the presets, personally, I don't want to use those for what I'm doing but it might be useful for certain game layouts, troubleshooting or games you are making you can also save custom layouts omg, finally I can do 1.2 :D c# scripting? just so its easier on other devs and you so it doesn't create problems down the line DONT RENAME YOUR SCRIPTS because if u do it might cause problems coz of how its written just name it what its intended to do then make more or merge and fix the bugs in the tutorial, u can just create a blank script in the project folder area and then drag it to the object but I can't? maybe it's a new unity thing BUT you can just create one as a new component c# = c sharp or .cs in the line of code which apparently doesn't need a ; public class PlayerController : MonoBehaviour so the : kind of means x inherits from y so, in this case, the 3rd word "PlayerController" inherits from the class "MonoBehaviour" so ig ill write in shorthand idrk what the tutorial guy means but the void is a method but sure ill go with it void Start() is called before the game starts (sort of) or before the first "frame" void Update() is called every "frame" ofc // means everything is a comment on that line from that // mark It's common practice to capitalize certain things and not capitalize others, ex. code with capital letters means its class but lowercase letters are components transform.Translate(0 , 0, 1); so you write code in this way ```csharp component.Method(arguments); ``` literally make it go vrooooomm and move forwards it uses x y z and its 1 unit per frame okok so now 4.Use a Vector3 to move forward transform.Translate(Vector3.forward); is literally the same thing but how do we make it so that its more than just along the z axis??? idk its just shorthand for that we use the Vector3 library ig we can modify that code to be like 20m/s with this transform.Translate(Vector3.forward \* Time.deltaTime \* 20); coz delta means change in y so delta time means change in time so this means using the vector3 library we will move forward by 1 unit \* 1 unit of time (second) \* 20 or 1 unit per second \* 20 or 20 units per second or 20u/s and since each unit is 1m its 20m/s OKOKOK so now RigidBody's they are component that means the object its assigned to are a physics object, we can give it gravity and other things with this sphere colider and mesh colider make it a coliable object and has different ways of interacting with the player/ a given object mass is done in kilos :D # New Page `public float speed = 5.0f;` the word public can be changed to private, this denotes the accessability of the variable/class/other `private float speed = 5.0f;` also this is done to initialize the default value of the variable in the script's component tab they are also known as access modifiers :D when we do 5 as a variable, its only valid as an intiger, a whole number, so if we want to do fractional speeds we need to make it a floating point, a decimal number, so we could do 5.0, but its not understandable because its a decimal number so since its not an intiger we need to use float to do decimals coz its a floating point number so then can do 5.0f to turn 5.0 into a readable understandable number for the game :D what happens when we do dword :D it doesn't tell us ;-; anyways next line of code this is similar to the public float speed = thing BUT it doesn't give us the number, or object its just a name normally this doesn't work unless you assign a value in some programming languages but with c# if the script is assigned to an object ex. the camera you can drag an object into the player variable to reference what the player variable is, so ex we want the tank to be the player, (later the player model) we can just put this code in the first level of the script in the public class and it will allow us to assign an object to the variable. whoa python is hard lmfao public GameObject Player; ok so next line in the void update() area transform.position = Player.transform.position;

![User](https://chat.openai.com/_next/image?url=https%3A%2F%2Flh3.googleusercontent.com%2Fa%2FAGNmyxYznFTCHQPRIoyzvpOPF9nvwe3_Ef9StfW1veunMQ%3Ds96-c&w=96&q=75)

so basically this transforming the position of the camera to be exactly the same as the Players, including its transformed(updated) position so since we want to offset that we can add `+ new Vector3(0, 5, -7)`

we need to use a new vector3 variable (xyz) but since we need to be able to change that I messed with the code more and got the ideal maybe ggz angels
