ATM the processes is as such:
generate - Generates land mass all tiles are loaded. (3000 from all others. but closest to spawn as it can find in least amt of tries)
check - Checks the chunks to see if they are loaded yet.
clear - Clears out biters in the loaded chunks. <--------------- give the same space between aliens
ore - Spawns ORE via remote call on RSO.
chart - Charts the area so the player can see the area.
teleport - Teleports the player to a random location that collides with land.
edit* Also no one gets the original starting area.
This is as close to fair as I can get the mod (RSO does a really good job at making it fair / spawning a starting area). Yes if you have 40 people joining it can put you very far away and you might have a lot of biters to deal with, but modifying the biter generation is not part of this mod. Feel free to improve on the mod or make an add-on that uses this mod if you can find a way of making it better. Please link me if you do. Thanks!
