Coding info

Introduction

This page has information which would be useful for anyone who is doing coding for MTA SA.

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.

• ushort = unsigned short
• uchar = unsigned char
• uint64 = unsigned long long
• uint32 = unsigned int
• uint16 = unsigned short
• uint8 = unsigned char
• int64 = signed long long
• int32 = signed int
• int16 = signed short
• int8 = signed char
• BYTE = unsigned char
• WORD = unsigned short
• DWORD = unsigned long
