== 全体の構造 ==

Minetestは常に、サーバーと0個以上の接続されているクライアントとして動作します。

== 関数 ==

=== main() ===
main.cpp

Minetestが起動すると、まずmain.cpp内のmain()関数が実行されます。これは全てのコマンドライン引数(サーバーとクライアント)、起動、メインメニュー(クライアント)の結果を処理します。

=== dedicated_server_loop() ===
server.{h,cpp}

When the dedicated server is run, main() ends up running this and when it returns, Minetest quits.

It basically just feeds time to the server instance created by main() and reacts to SIGKILL etc.

=== the_game() ===
game.{h,cpp}

Launched when you start the game from the main menu.

This creates the client (and the server, if needed), handles the waiting of loading stuff from the server, and runs the game in a somewhat badly structured main loop (which works well, though).

== Threads ==

=== Stand-alone server ===
* main
:* Doesn't do much
* ServerThread (Server)
:* Runs the server
* EmergeThread (Server)
:* Fetches and generates world

=== Client-only ===
* main
:* Runs almost everything in main game loop
* MeshUpdateThread (Client)
:* Does mesh updates in the background

=== Singleplayer ===
* main
:* Runs almost everything except server in main game loop
* MeshUpdateThread (Client)
:* Does mesh updates in the background
* ServerThread (Server)
:* Runs the server
* EmergeThread (Server)
:* Fetches and generates world

== Classes ==

=== IGameDef ===
An interface for fetching pointers to the managers of things. It is passed to almost everything.

It is implemented by Client and Server. Neither implements all interfaces.

Generally these can be accessed by referring to IGameDef:
* TextureSource
* ItemDefManager
* NodeDefManager
* SoundManager
* MtEventManager

This is the main difference between 0.3 and 0.4. In 0.3 this does not exist, because all content is defined in static tables in source code.

gamedef.{h,cpp}

=== TextureSource ===
Fetches, generates and caches textures.

tile.{h,cpp}

=== ItemDefManager ===
Stores the definitions of items, by item name. Content is set up at server startup, and transferred from server to client at beginning of connection.

itemdef.{h,cpp}

=== NodeDefManager ===
Stores the definitions of nodes and the mapping between node ids and names. Content is set up at server startup, and transferred from server to client at beginning of connection.

nodedef.{h,cpp}

=== SoundManager ===
Stores and plays sounds on the client.

sound.{h,cpp}; sound_openal.{h,cpp}

=== MtEventManager ===
A minimal event manager currently only used for triggering sounds on the client.

event.{h,cpp}

=== Client ===
Contains a lot of stuff. Most considerable members are listed here.
* TextureSource
* ItemDefManager
* NodeDefManager
* SoundManager
* MtEventManager
* MeshUpdateThread
* ClientEnvironment
:* ClientMap
:* Players
:* ClientActiveObjects (CAOs)
* Connection

Implements IGameDef.

client.{h,cpp}

=== Server ===
Contains a lot of stuff. Most considerable members are listed here.
* ServerEnvironment
:* ServerMap
:* Players
:* ServerActiveObjects (SAOs)
* Connection
* BanManager
* Lua State
* ItemDefManager
* NodeDefManager
* CraftDefManager
* ServerThread
* EmergeThread

Implements IGameDef.

server.{h,cpp}

=== [[Script Engine]] ===
script/*

The script engine contains "core to script"- as well as "script to core"-interface implementation.

=== Connection ===
Connection (client->server or server->clients)

=== ClientEnvironment (Environment) ===
Contains most of the actual game environment (players, objects, map...)

* ClientMap
* Players
* ClientActiveObjects (CAOs)

environment.{h,cpp}

=== ServerEnvironment (Environment) ===
Contains the actual game environment (players, objects, map, time of day, ...)

* ServerMap
* Players
* ServerActiveObjects (SAOs)

environment.{h,cpp}

=== ClientMap (Map) ===

map.{h,cpp}, clientmap.{h,cpp}

=== ServerMap (マップ) ===

map.{h,cpp}
