Four types of data:
- Bool
- Int
- Float
- String
Can typecast dynamic variables. Easy and flexible
While static variables are Safe and Performant. Eg:

var damage: int = 15
# OR
var damage := 15

Build-in functions, starts with func _input(), called by engine.
Static functions:

func add(a: int, b: int) -> int:
	return a + b

Random numbers:

const RNG = randf() # 0 to 1.
const A = randi_range(140, 200)

Static arrays:

var arr: Array[String] = ["a", "b", "c"]
arr.remove_at(1)
arr.append("d")

Looping arrays and dictionaries

func _ready():
	for i in 10:
		print(i)
	
	var charac = {
		"Enemy" : {"health": 100, "damage": 20},
		"Player": 12
	}

	for c in charac:
		print(c, charac[c])

Enums: is a datatype that contains a fixed set of Constants.

enum AnimationState {IDLE, JUMP, RUN}

var state = AnimationState.IDLE

@export var state : AnimationState

Can export enum defined variables to change using inspector.

Match: is switch-case of Godot.

enum AnimationState {IDLE, JUMP, RUN}

var animation = AnimationState.RUN

func _ready():
	match animation:
		AnimationState.IDLE:
			print("zzz")
		AnimationState.JUMP:
			print("weee")
		AnimationState.RUN:
			print("aahhhh")
		_:
			print("wtf")

@onready waits until all child nodes have been created.

$path is shorthand for writing get_node("path")
