Hello, I've tryed to search a bit, but haven't found anything.
(I'm on a slow internet at the moment so I haven't searched that much, sorry if there is another topic about this)
But, I'm in my making of my servers house/ doors saving system etc.
So I wonder wich is fastest to use either pickups or checkpoints?
and should i use a variable to see if the player is in a checkpoint before i start loop thing all doors on the /enter cmd?

I'm thankfull for every answer
