# VARIABLES | DATA TYPES                                   |
#-----------------------------------------------------------
# String
var name = "Tutorial Dcotor"

# Integer
var age = 29

# Float
var height = 6.1

# Array
var friends = ['Albert','Bobby','Cynthia','Donny']

# Dictionary
var favorites = {'number':4,'food':'fish'}

# Boolean
var cool = true

# Exporting Variables
export var gameName = "CoderDojo Game"
# Exports the variable to the Inpspector for easy editing

# GAME FUNCTIONS | LOOPS                                   |
#-----------------------------------------------------------
# For and While loops can be used inside of the _ready() function.
# Don't use For and While loops in the "Game Loop" (the _process() function).
# This includes using them in your own functions that will be called under the game loop.

# The Setup Function
#-----------------------------------------------------------
func _ready():
	set_process(true)
	set_fixed_process(true)
	print(getInfo())
	print(friends[2])
	print(favorites['number'])
	checkCoolness()
	
	# For Loop
	for friend in friends:
		print(friend)
	
	# While Loop
	var i = 0
	while i < 5:
		print('Hello Developer')
		i+=1

# The Game Loop
#-----------------------------------------------------------
# A game loop is a function that repeats code at a standard rate. For games this is ideally 60 frames a second.
# Code within this loop runs every game frame.
func _process(delta):
	pass
#-----------------------------------------------------------

# The Physics Loop
#-----------------------------------------------------------
# The physics loop repeats code every physics frame. Updates to phyics are done here.
func _fixed_process(delta):
	pass
#-----------------------------------------------------------

# CLASSES | OBJECTS                                        |
#-----------------------------------------------------------
# Every node is an object 
# The 'extends' statement extends a class and effectively makes the current script a subclass of the extended class.
# Member variables are declared outside of the _ready(), _process() and _fixed_process() functions.
# All functions you create in this script become class functions (methods).
# Simply put, the 'extends' statement extends the functionality of the class being extended. It let's you add more features!
# The variables at the top of this script are memeber variables
