Godot - Delete a node

This is how to delete a node using GDScript in Godot 4.

You can delete a node using queue_free().

queue_free() has the following characteristics:
- Node to delete is itself or specified target
- Deletion is executed at the end of frame processing

target.queue_free()

By removing the child node with the remove_child() function from the parent element, the node can be deleted within the corresponding frame.

remove_child(target)
target.queue_free()
