GetEntitiesWithinAABBExludingEntity is not returning entities within boundingbox

Jershy · February 15, 2015

I am trying to get the entities within the target entity of the same type to compare variables to affect gameplay

I know for a fact there are other entities within it bounding box yet not printing the message n the ide console.

this is my code

Though I can't tell immediately with the code you provided, but it could be that the chunk you are checking isn't loaded. worldObj.getEntitiesWithinAABB checks whether or not the chunk is loaded before it determines which entities are within the specified area. Double check that the chunk is loaded by using 'worlObj.chunkExists(chunkCoordX, chunkCoordY)'.
