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

9. 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:

10. 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

Searches
the map for
enemies and
returns the #

11. 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

12. 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)

13. 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

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

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

16. Input
Detecting PlayerInput (Mouse movement and Key presses)

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

18. Prefabs
Creating assets for instancing and updating scene

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