godot-dollarsign-example.gd

func die()->bool:
    hide()
    # Accessing the node NAMED CollisionShape2D in the UI.
    # If There were subchildren of that node, we'd access it like so $CollisionShape2D/ChildNode
    $CollisionShape2D.set_deferred("disabled", true)
    queue_free()
    return true
 

# Alternate Syntax
func die_type_2()->bool:
    hide()
    # Accessing the node NAMED CollisionShape2D in the UI.
    # This syntax is useful if you want to chain gets with the dot operator; dollar sign does not work with the operator.
    get_node("CollisionShape2D").set_deferred("disabled", true)
    queue_free()
    return true
