+				Returns an array of object IDs intersecting with the provided 3D ray. Only visual 3D nodes are considered, such as [MeshInstance] or [DirectionalLight]. Use [method @GDscript.instance_from_id] to obtain the actual nodes. A scenario RID must be provided, which is available in the [World] you want to query.
+				Warning: this function is primarily intended for editor usage. For in-game use cases, prefer physics collision.
