# Available only in the 2.2 legacy branch and posterior versions

func _ready():

	# The old way:
	print("HELLO") 			# Code before the yield
	# Setting up the yield:
	var t = Timer.new() 		# Create a new Timer node
	t.set_wait_time(5.5) 		# Set the wait time
	add_child(t)			# Add it to the node tree as the direct child
	t.start()			# Start it
	yield(t, "timeout")		# Finally, make the script stop with the yield
	print("WORLD")			# Code that will be exectued after the yield
	print("=====")
	
	
	# The optional new way:
	
	print("HELLO AGAIN!") 		# Code before the yield
	
	# Setting up the yield with the new function 'create_timer()':
	yield(get_tree().create_timer(5.5),"timeout")
	print("WORLD")			# Code that will be exectued after the yield
