To be honest, this can be done with the relative doPlayerTeleport to a place a long distance away.
Please, just do this, for several reasons:
1. Blockland used to have a deleteBrick event but it was removed because it could be used it ways that results in bricks you didn't have full trust with being deleted. Any recreation of it is likely to be failed
2. This would only be usable in single player, as traveling through a door to delete the bricks would forget over anyone else still in that room
3.
It also reduces stress on the server as it does not have to load a whole room every time you walk through the door.
Continuously deleting and reloading the same bricks is silly. Although it would be less of a problem considering it would only work on single player, it still results in more downtime, you'll have to reload the area every single time you leave and come back to it, whereas with using teleport to distant areas, you only have to load it the first time you go there
4. It's much easier to set up a simple teleport, than making a ton of individual saves, and matching their names up
5.
This is meant to be for singleplayer but yeah that's what I wanted, being frozen until bricks are done loading. Also should make them invincible too so baddies can't hurt you while you load.
How about when the save is loaded, any nearby people with that player type are frozen until the save is done being loaded?
There is no serverside function to tell when a client is done loading bricks
