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.
| area block | result | |||
|---|---|---|---|---|

| air | air | air | air | air |
| A | air | air | A | A |
| air | B | B | B | B |

So to sum up:

This class implements a simple name-value storage represented on disk by an INI file. These files
are suitable for low-volume high-latency human-readable information storage, such as for
configuration. MCServer itself uses INI files for settings and options.
The INI files follow this basic structure:
; Header comment line [KeyName0] ; Key comment line 0 ValueName0=Value0 ValueName1=Value1 [KeyName1] ; Key comment line 0 ; Key comment line 1 ValueName0=SomeOtherValueThe cIniFile object stores all the objects in numbered arrays and provides access to the information either based on names (KeyName, ValueName) or zero-based indices.
The objects of this class are created empty. You need to either load a file using ReadFile(), or insert values by hand. Then you can store the object's contents to a disk file using WriteFile(), or just forget everything by destroying the object. Note that the file operations are quite slow.
For storing high-volume low-latency data, use the {{sqlite3}} class.

|---|---|---|
| OnNextBlock | BlockX, BlockY, BlockZ, BlockType, BlockMeta, EntryFace | Called when the ray hits a new valid block. The block type and meta is given. EntryFace is one of the BLOCK_FACE_ constants indicating which "side" of the block got hit by the ray. |
| OnNextBlockNoData | BlockX, BlockY, BlockZ, EntryFace | Called when the ray hits a new block, but the block is in an unloaded chunk - no valid data is available. Only the coords and the entry face are given. |
| OnOutOfWorld | X, Y, Z | Called when the ray goes outside of the world (Y-wise); the coords specify the exact exit point.

| OnIntoWorld | X, Y, Z | Called when the ray enters the world (Y-wise); the coords specify the exact entry point. |
| OnNoMoreHits | Called when the path is sure not to hit any more blocks. This is the final callback, no more callbacks are called after this function. Unlike the other callbacks, this function doesn't have a return value. | |
| OnNoChunk | Called when the ray enters a chunk that is not loaded. This usually means that the tracing is aborted. Unlike the other callbacks, this function doesn't have a return value. |

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.

Instead, the cWorld provides access to these objects using callbacks. The plugin provides a function that is called and receives the object as a parameter; cWorld guarantees that while the callback is executing, the object will stay valid.

With an event-based API like SAX the XML document can be fed to the parser in chunks, and the parsing begins as soon as the parser receives the first document chunk. LuaExpat reports parsing events (such as the start and end of elements) directly to the application through callbacks. The parsing of huge documents can benefit from this piecemeal operation.
