Proper method for determining if a block/chunk is loaded


Recommended Posts



I'm in the process of writing a new mod using ML/Forge and need to figure out the proper way to determine if a specific x,y,z location is loaded or not. There is a rare case that could happen with my mod where the chunk our block is in is loaded but the directly adjacent block which I need to interact with is in another chunk which has been unloaded. I need to be able to reliably test for this state in both SSP and SMP so I can handle it appropriately.


I've looked at world.blockExists(x,y,z) but I'm concerned that that isn't really doing what I want it to do and could return false if the specific x,y,z location is loaded, but there's just air there. Am I wrong in my understanding of world.blockExists function?
