[TF2] Friendly Fire Fix

A SourceMod plugin for Team Fortress 2 that fixes broken interactions during friendly fire.

Note

This plugin does nothing if mp_friendlyfire is not enabled.

Requirements

• SourceMod 1.12+
• Mikusch/PluginStateManager (compile only)

What Does This Do?

mp_friendlyfire allows teammates to damage each other, but the vast majority of weapons and mechanics were not made with it in mind, and thus do nothing if two players are on the same team. This plugin hooks into various game functions to rewrite and fix that behavior.

Note

The following changes only apply while mp_friendlyfire is 1.

Free-for-All Mode

sm_friendlyfire_teammates_are_enemies is a separate opt-in that goes considerably further, and it stops teammates from counting as teammates at all. Interactions that were never meant for your own team start working on them, and every friendly interaction stops. It effectively turns the game into a free-for-all.
