Adds the node to a group. Groups are helpers to name and organize a subset of nodes, for example "enemies" or "collectables". A node can be in any number of groups. Nodes can be assigned a group at any time, but will not be added until they are inside the scene tree (see [method is_inside_tree]). See notes in the description, and the group methods in [SceneTree]. Adds the node to a group. Groups are helpers to name and organize a subset of nodes, for example "enemies" or "collectables".
