Question about Groups.

UpAllNight

var spawn  = get_tree().get_nodes_in_group("shipspawnpoint")

Are the lists created by groups cleared when I remove the scene ? or will I have to manage cleaning that list when I change scenes?

Or should i just call a spawn.erase() ? to be safe, or i could provoke an error.

The groups got with that function return the nodes that exist in the tree. If you remove a node (using remove_child) then it won't be returned by that function. However, the spawn variable is fixed and is not updated when nodes change. You will have to call get_nodes_in_group to refresh it before doing anything.

Okay, I think I'm seeing my problem here then.. My Autoload control script is running the check on object placements before the scene is actually fully loaded. I'm using get_tree().change_scene to switch my levels out, there must be some lag between the reload and the time my logic calls out for node groups.

Hmmm I need to check and make sure the map is fully loaded before starting logic.. Any pointers? :)

The ready on the root node of the loaded scene will be what you want. You can either put the code in the ready function on that root node on that scene, or use the autoload to attach a signal to listen for ready.
