I've been reading through the source because I'm interested in how Minecraft works from a programming point of view.
So far I've found Block.java and IBlockAccess.java, and they have methods such as "isAirBlock(x,y,z)" etc.
However I cannot find anywhere in the source where or how it keeps blocks in memory. For example, are the blocks kept in some kind of three dimensional array or list that is declared in "Chunk.java"?
The nearest I've been able to find is:
/** List of ly/ff (BlockType) containing the already registered blocks. */
public static final Block[] blocksList = new Block[4096];
However by the looks of it, that is just used for registering new block types.
