# Changing scenes is most easily done using the functions `change_scene`
# and `change_scene_to` of the SceneTree. This script demonstrates how to
# change scenes without those helpers.
func goto_scene(path):
# This function will usually be called from a signal callback,
# or some other function from the running scene.
# Deleting the current scene at this point might be
# a bad idea, because it may be inside of a callback or function of it.
# The worst case will be a crash or unexpected behavior.
# The way around this is deferring the load to a later time, when
# it is ensured that no code from the current scene is running:
call_deferred("_deferred_goto_scene",path)
func _deferred_goto_scene(path):
# Immediately free the current scene, there is no risk here.
get_tree().get_current_scene().free()
# Load new scene
var packed_scene = ResourceLoader.load(path)
# Instance the new scene
var instanced_scene = packed_scene.instance()
# Add it to the scene tree, as direct child of root
get_tree().get_root().add_child(instanced_scene)
# Set it as the current scene, only after it has been added to the tree
get_tree().set_current_scene(instanced_scene)
