cBlockArea =
{
Desc = [[
This class is used when multiple adjacent blocks are to be manipulated. Because of chunking
and multithreading, manipulating single blocks using {{cWorld|cWorld:SetBlock}}() is a rather
time-consuming operation (locks for exclusive access need to be obtained, chunk lookup is done
for each block), so whenever you need to manipulate multiple adjacent blocks, it's better to wrap
the operation into a cBlockArea access. cBlockArea is capable of reading / writing across chunk
boundaries, has no chunk lookups for get and set operations and is not subject to multithreading
locking (because it is not shared among threads).</p>
<p>
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.</p>
<p>
cBlockArea can hold any combination of the following datatypes:<ul>
<li>block types</li>
<li>block metas</li>
<li>blocklight</li>
<li>skylight</li>
</ul>
Read() and Write() functions have parameters that tell the class which datatypes to read / write.
Note that a datatype that has not been read cannot be written (FIXME).</p>
<p>
Typical usage:<ul>
<li>Create cBlockArea object</li>
<li>Read an area from the world / load from file / create anew</li>
<li>Modify blocks inside cBlockArea</li>
<li>Write the area back to a world / save to file</li>

To manipulate block entities while the chunk is generated, first use SetBlockTypeMeta() to set
the correct block type and meta at the position. Then use the GetBlockEntity() to create and
return the correct block entity instance. Finally, use tolua.cast() to cast to the proper
type.</p>
Note that you don't need to check if a block entity has previously existed at the place, because
GetBlockEntity() will automatically re-create the correct type for you.</p>

cEntity =

A cEntity object represents an object in the world, it has a position and orientation. cEntity is an
abstract class, and can not be instantiated directly, instead, all entities are implemented as
subclasses. The cEntity class works as the common interface for the operations that all (most)
entities support.</p>
<p>
All cEntity objects have an Entity Type so it can be determined what kind of entity it is
efficiently. Entities also have a class inheritance awareness, they know their class name,
their parent class' name and can decide if there is a class within their inheritance chain.
Since these functions operate on strings, they are slightly slower than checking the entity type
directly, on the other hand, they are more specific directly. To check if the entity is a spider,
you need to call IsMob(), then cast the object to {{cMonster}} and finally compare
{{cMonster}}:GetMonsterType() to mtSpider. GetClass(), on the other hand, returns "cSpider"
directly.</p>
<p>
Note that you should not store a cEntity object between two hooks' calls, because MCServer may
despawn / remove that entity in between the calls. If you need to refer to an entity later, use its
UniqueID and {{cWorld|cWorld}}'s entity manipulation functions DoWithEntityByID(), ForEachEntity()
or ForEachEntityInChunk() to access the entity again.</p>

The INI files follow this basic structure:
<pre class="prettyprint lang-ini">
; Header comment line
[KeyName0]
; Key comment line 0
ValueName0=Value0
ValueName1=Value1
[KeyName1]

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.</p>

cWorld is the game world. 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.</p>
<p>
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.</p>
<p>
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.</p>
<p>
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).</p>
<p>
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.</p>
<p>
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.</p>
<p>
Game time is also handled by the world. It provides the time-of-day and the total world age.

To avoid problems with stale objects, the cWorld class will not let plugins get a direct pointer
to an {{cEntity|entity}}, {{cBlockEntity|block entity}} or a {{cPlayer|player}}. Such an object
could be modified or even destroyed by another thread while the plugin holds it, so it would be
rather unsafe.</p>
<p>
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. If a plugin needs to "remember" the
object outside of the callback, it needs to store the entity ID, blockentity coords or player
name.</p>
<p>
The following code examples show how to use the callbacks</p>
<p>
This code teleports player Player to another player named ToName in the same world:
<pre class="prettyprint lang-lua">
-- Player is a cPlayer object
-- ToName is a string
-- World is a cWorld object
World:ForEachPlayer(
function (a_OtherPlayer)
if (a_OtherPlayer:GetName() == ToName) then
Player:TeleportToEntity(a_OtherPlayer);
end
);
</pre></p>
<p>
This code fills each furnace in the chunk with 64 coals:
<pre class="prettyprint lang-lua">
-- Player is a cPlayer object
-- World is a cWorld object
World:ForEachFurnaceInChunk(Player:GetChunkX(), Player:GetChunkZ(),
function (a_Furnace)
a_Furnace:SetFuelSlot(cItem(E_ITEM_COAL, 64));
end
);
</pre></p>
<p>
This code teleports all spiders up by 100 blocks:
<pre class="prettyprint lang-lua">
-- World is a cWorld object
World:ForEachEntity(
function (a_Entity)
if not(a_Entity:IsMob()) then
return;
end
local Monster = tolua.cast(a_Entity, "cMonster"); -- Get the cMonster out of cEntity, now that we know the entity represents one.
if (Monster:GetMobType() == cMonster.mtSpider) then
