A Spawn Function

Part of the Game Rules section of Coddy's Godot journey. Lesson 18 of 29.

Making a node while the game runs is called spawning. Put the spawn lines in your own function, with the x position as a parameter:

func spawn(x):
	var block = block_scene.instantiate()
	block.position = Vector2(x, -30)
	add_child(block)

Each call builds a new block. A node can be in the game only once. Calling add_child() twice with the same block is an error. So every block needs its own instantiate().

Challenge

Easy

Drop three blocks with one function.

Write func spawn(x) that makes a block at Vector2(x, -30) and adds it.
In _ready(), call it three times: spawn(160), spawn(320) and spawn(480).

Press Play: three blocks fall side by side. Then Check.

Try it yourself

extends Node2D

var block_scene = preload("res://block.tscn")

func _ready():
	var block = block_scene.instantiate()
	block.position = Vector2(160, -30)
	add_child(block)
