how can I use get_children() after I used queue_free() or free() on a node?

I have a main node A and a sub node of A called “B”, the problem is when I
queue_free() to node b and tries to see how many nodes in A it gives me the same number. I’m testing how many nodes inside A by using get_children() inside _physics_process(delta) function for testing purposes.

queue_free() does not delete a Node immediately so if you check children right after calling it you won’t see any change.

You may queue_free a Node and then remove it from tree


At this point B will not be a child of A, although it won’t be destroyed yet.

free() function deletes a Node immediately but SceneTree is in some cases locked and no nodes can be removed from it. To make sure SceneTree isn’t locked use call_deferred

func foo():

func deleteB():

Thank you , i understood many things from your comment.
