A spawner go through all children objects that are the positions where to spwan, and spawn the object type.
I used empty objects for spawners, but it has disadvantages :
- you don’t know what you spawn
- positionning is not precise as you don’t know the size of the object or it if touches the ground.
A good solution is to use a low poly object mesh representation as visualization instead of empty nodes, those mesh visualization will only be visible in editor and not visible in game.
