FacelessStalkerFix

FacelessStalkerFix

Compatibility fix for FacelessStalker (Slenderman mod by Sparble) on modern Lethal Company versions (v50, v55, v60, v68, v73+).

The Issue

In modern Lethal Company updates, multiple base game method signatures were changed:

• GameNetcodeStuff.PlayerControllerB.HasLineOfSightToPosition received an additional int layerMask = -1 parameter (expanded from 4 to 5 arguments).
• GameNetcodeStuff.PlayerControllerB.KillPlayer received an additional bool setOverrideDropItems parameter (expanded from 5 to 6 arguments).

Because SlendermanMod.dll was compiled against older game binaries, calling these methods caused immediate runtime crashes:

[Error: Unity Log] MissingMethodException: Method not found: bool GameNetcodeStuff.PlayerControllerB.HasLineOfSightToPosition(UnityEngine.Vector3,single,int,single)

The Fix

This BepInEx preloader patch dynamically rewrites outdated IL instructions in SlendermanMod.dll at launch or on disk:

• Updates PlayerControllerB.HasLineOfSightToPosition call-sites to pass the modern default layer mask (-1).
• Updates PlayerControllerB.KillPlayer call-sites to pass the modern default parameters.
• Restores full functionality to Slenderman's haunting, line-of-sight tracking, and kill mechanics without modifying original game logic.
