I would like to save blocks into an.. array kind thing and save them into a file, database or whatever. i would have to do that for 256 blocks PER CHUNK! sooo.. I have the y of the block, the x and the z. And the meta. and id. for 16*16 blocks. per chunk. Any efficient way? Also, when a block changes i would have to update that chunk file. And i must be able to get the data of a block at the specific x-y-z values.
