Architecture of the Lua Executor

4. Native Caller – Invoking GTA V Natives

GTA V natives are C++ functions called via a hashed index. You can find them in the game’s script tables. Understanding FiveM Lua Executors: A Deep Dive into

Lua's popularity in game development, particularly in FiveM, can be attributed to its: Stack Walking: FiveGuard constantly checks the call stack

The goal of the executor is to find the Lua state and push a string of code into it. A simplified version of the logic looks like this: // Example logic for a function that executes a Lua string ExecuteLua( std::string& script) // 1. Locate the CfxLua state in memory

• Stack Walking: FiveGuard constantly checks the call stack. If lua_loadstring is called from a heap-allocated memory region (a DLL) instead of the FiveM executable, it triggers a ban.
• CFG (Control Flow Guard): Windows CFG prevents indirect calls to non-validated locations.
• Integrity Checks: It hashes critical Lua functions periodically. If lua_pcall has been modified (a hotpatch), the game crashes.
