cBlockArea remembers its origin (MinX, MinY, MinZ coords in the Read() call) and therefore supports absolute as well as relative get / set operations. Despite that, the contents of a cBlockArea can be written back into the world at any coords.
cBlockArea can hold any combination of the following datatypes:
Typical usage:
The strategy parameter specifies how individual blocks are combined together, using the table below.

It is the hub of all the information managed by individual classes, providing convenient access to them. MCServer supports multiple worlds in any combination of world types. You can have two overworlds, three nethers etc. To enumerate all world the server provides, use the {{cRoot}}:ForEachWorld() function.
The world data is held in individual chunks. Each chunk consists of 16 (x) * 16 (z) * 256 (y) blocks, each block is specified by its block type (8-bit) and block metadata (4-bit). Additionally, each block has two light values calculated - skylight (how much daylight it receives) and blocklight (how much light from light-emissive blocks it receives), both 4-bit.
Each world runs several separate threads used for various housekeeping purposes, the most important of those is the Tick thread. This thread updates the game logic 20 times per second, and it is the thread where all the gameplay actions are evaluated. Liquid physics, entity interactions, player ovement etc., all are applied in this thread.
Additional threads include the generation thread (generates new chunks as needed, storage thread (saves and loads chunk from the disk), lighting thread (updates block light values) and the chunksender thread (compresses chunks to send to the clients).
The world provides access to all its {{cPlayer|players}}, {{cEntity|entities}} and {{cBlockEntity|block entities}}. Because of multithreading issues, individual objects cannot be retrieved for indefinite handling, but rather must be modified in callbacks, within which they are guaranteed to stay valid.
Physics for individual blocks are handled by the simulators. These will fire in each tick for all blocks that have been scheduled for simulator update ("simulator wakeup"). The simulators include liquid physics, falling blocks, fire spreading and extinguishing and redstone.
