Introduction
This page has information which would be useful for anyone who is doing coding for MTA SA. Coding guidelines also has a lot of useful info.
Projects explained
- Client - Core: Typically UI elements like main menu etc and isn't ever unloaded.
- Client - Deathmatch: Where MTA makes all it's functions and events do stuff.
- Client - Game SA: Low level stuff which is mainly function calls to the game so each element will have a game_sa class like Vehicle, Ped, Object etc.
- Client - GUI: It's just wrappers to CEGUI, you need not touch.
- Client - Launch: Is the MTA executable which loads loader, you need not touch.
- Client - Loader: You need not touch the loader either.
- Client - Multiplayer SA: Hooks, code modification and that sort of low level things that lets us work.
- Server - Core: Cazomino05: "I genuinely don't really know why we have server core."
- Server - Dbconmy: Stuff to do with the db* functions, you need not touch.
- Server - Deathmatch: All the server logic and storage classes for elements as well as Lua stuff.
- Server - Launcher: Just an executable to load all the DLLs we need.
- Shared - XML Module: XML module is just tinyxml and some high level wrapper functions for stuff we need.
- Dependencies: Has a load of 3rd party code, modules like sqlite, curl, lua, ehs, etc.
- CEGUI: Crazy Eddie's GUI system is a graphical user interface C++ library.
Some of the code may be explained in detail in pages under the this category: Classes (Blue)
