Variables name “John Doe” name string Variable: Something that stores information playerName health <variabletype> <variablename> = <variablevalue> Modifying a variable: “John Doe” name string

Functions Function / Method: A group of code that can run SaveGame DoDamage Functions execute code once each time the function is called Function body: Calling a function:

doubles <value> Functions void OnHit() void OnHit(int damage) Function just executes Function executes AND Needs Input int GetEnemyCount() int DoubleValue(int value) Function executes AND Function executes AND returns value needs input Code inside the function reduces health by <damage> Code inside the function reduces health int int Searches the map for enemies and returns the # Code inside the function doubles <value> and returns it int int

Code Grouping In C#, all code is grouped, and sub-grouped. For this we use curly brackets. { = opening curly bracket } = closing curly bracket MyGame Program MyFunction MyOtherFunction

Creating & adding scripts to Game Objects Start, Update (+ Awake, FixedUpdate, ...) OnTriggerEnter, OnTriggerExit Instantiating & Destroying GameObjects from scripts Accessing variables from the Editor (public, private, serializable)

Time.deltaTime Time.deltaTime = time between updates Update() has a variableTime.deltaTime FixedUpdate() has a fixed Time.deltaTime 5 FPS = 5 Frames per Second 60 FPS = 60 Frames per Second

Rigidbody Collisions & Triggers Physics using Rigidbody & AddForce OnTriggerEnter and OnTriggerExit

Character Controller Using a Character Controller to control and move a character

Input Detecting PlayerInput (Mouse movement and Key presses)

Jumping logics Applying gravity constantly vs. Applying gravity at a variable intensity

Prefabs Creating assets for instancing and updating scene

Audio & importing custom assets Playing sounds / Music using AudioSource and AudioClips
