Scripting Cyberpunk

Welcome to script modding!

This wiki hosts common information on scripting with Cyberpunk independent of implementation.

You have four options to write scripts for Cyberpunk:

• REDmod
• Redscript (Swift-like)
• Cyber Engine Tweaks (Lua)
• RED4ext (C++)

You can also develop C# extensions for RED4ext.

How does stuff work in Cyberpunk?

The executable

Most of the game is implemented in C++ and only accessible through the game's executable (.exe file). Fortunately, RED4ext and Cyber Engine Tweaks hook into that, and Codeware provides and extends a common interface for both.

The hooks are dependent on binary addresses, which is why the core mods are version dependent (and why cracked games don't mod well).

Scripts

Scripts are precompiled into r6/cache/final.redscripts . As the file extension suggests, they can be modded with redscript.

The tweak database

Any properties of game items and characters are defined in the tweak database. You can learn more about it under Cyberpunk 2077 Modding -> Tweaks
