Check if Position is Clear

what would be the best way for an object spawner to check if a position is clear for spawning? keep in mind, its checking for objects spawned by ANOTHER spawner, so i cant just getDistanceTo(everyObjectInTheFrigginGame)

You could create an invisible, “ghost” plane or cube which floats in midair such that any object at that position would have to touch it, and then only allow the spawner to create an object at that location if the cube is not colliding with anything. Just be sure that the spawner object doesn’t interfere with the collision detection.
