The Script Component

24

Scripting

• C#

• Developed by Microsoft (.NET)

• Object Oriented

• Component Based

25

Language Elements

• Variables

• Control Structures

• Functions

• Classes

26

VariablesVariables● Various Data Types

○ bool, char, byte, float, double, int, string, …● Public vs Private keyword● Pass by reference: use ref instead of &

Example:public int playerHealth=5;

27

Control Structures

• Execution Flow

- if then else

• Loops

- for

If Statementsif (m > 10){ //do something}else{ //do something}

For Loop

for (int i = 1; i <= 5; i++){ Debug.Log(“hello”);}

28

Functions

• Called Methods in C#Functions (called methods in C#)

● allows us to compartmentalize and reuse code effeciently

public int SquareANumber(int number){ return number * number;}

29

Basic Unity Functions

• Awake()

• Start()

• Update()

• FixedUpdate()

• LateUpdate()

30

Start / Update• Run Automatically during PlayBasic Functions

void Start(){ //called once. do any initialization here}void Update(){ //called every frame. move objects here}
