Get surrounding chunks

Code:

Player p = event.getPlayer();
      Chunk chunk = p.getWorld().getChunkAt(p.getLocation());
      EntityPlayer player = ((CraftPlayer) p).getHandle();
      for (int i = -16; i <= 16; i = i + 16) {
        for (int a = -16; a <= 16; a = a + 16) {
          chunk = p.getWorld().getChunkAt(p.getLocation().getBlockX() + i,
              p.getLocation().getBlockZ() + a);
          player.chunkCoordIntPairQueue.add(new ChunkCoordIntPair(chunk.getX(),
              chunk.getZ()));
        }
      }

So for some reason or another, this doesn't work.
Could someone explain why and how I should do it?

 

I believe getChunkAt accepts the coordinate of the chunk, so the chunk that is blocks 16-31 is called chunk 1.

 

That is indeed correct - you need chunk co-ordinates, not block co-ordinates. Divide by 16 or bit-shift by 4, e.g.:

PHP:

chunk = p.getWorld().getChunkAt((p.getLocation().getBlockX() + i) >> 4,
              (p.getLocation().getBlockZ() + a) >> 4);


 

Thanks
