Hey all,

 

So, I am getting this in my log when I go to the nether while running my mod. Pretty sure this code here is the culprit. It runs whenever a mob spawns. How would I go about solving this issue?

CODE:

private static void findTileEntity(LivingSpawnEvent.CheckSpawn event, int radius)
{
  BlockPos pos = event.getEntity().getPosition();

  int chunkPosX = pos.getX() >> 4;
  int chunkPosZ = pos.getZ() >> 4;

  if (!event.getWorld().isRemote)
  {
    for (int x = chunkPosX - radius; x < chunkPosX + radius; x++)
    {
      for (int z = chunkPosZ - radius; z < chunkPosZ + radius; z++)
      {
        Map<BlockPos, TileEntity> currentChunkTE = event.getWorld().getChunkFromChunkCoords(x, z).getTileEntityMap();
        for (TileEntity te : currentChunkTE.values())
        {
          if (te != null)
          {
            if (te instanceof TileEntityBlockBase && radius == 12)
            {
              denySpawning(event, (TileEntityBlockBase) te);
            }
          }
        }
      }
    }
  }
}

 

Edit: This seems to only happen in The Nether. It DOES NOT happen in either the Overworld or The End.

It also seems to happen in chunks just outside my render distance. (Lazy Chunks?) This fact is only crudely tested though.

The answers in this thread might be helpful.

So, I've researched further, reading that post, and a couple others. The most I can get from them is having to offset by 8. It also seems to only affect those who are actually populating chunks. My code is doing nothing of the sort. Where would I offset by 8 in my code?

6 hours ago, MSpace-Dev said:

event.getWorld().getChunkFromChunkCoords(x, z).getTileEntityMap();

I’m pretty sure that this loads new chunks. 

Yeah, figured. How would the offset work though?

You wouldn’t. Do you really need to load the 12 chunks near every entity that spawns?

Yeah, no. I can make it a fair bit smaller. Will give that a shot.

However, why on earth does it only happen in the Nether? That doesn't make sense. Overworld and End do not produce this warning.
