Friendly Fire Denial
by pivosos2007
Friendly Fire Denial stops players from damaging allied living entities, so accidental hits and miss-clicks on teammates do nothing.
What it does
Once active, the client blocks damage dealt to allied living entities, which covers teammates and pets that a stray attack would otherwise hurt. The effect applies only on the player's own client, and it is a single toggle rather than a server rule.
The mod is a Fabric client mod that needs Fabric API. Mod Menu is optional and adds an entry for its settings screen. It is client-side only, so servers need nothing, and the code is released under the Apache License 2.0, though it is not open source. Builds cover 1.21.6 – 1.21.8, with 1.1 for 1.21.8 as the latest file, first published 2025-07-01 and last updated 2025-08-30.
Key features
Ally damage blocking
Damage a player would deal to allied living entities is cancelled, which keeps cooperative fights and builds safe from miss-clicks.
Enable and disable toggle
A widget in the settings screen switches the protection on or off without restarting the game.
Clear button for selections
The Clear button empties only the selected list, leaving the rest of the configuration in place.
Scrollable lists
The lists in the interface scroll with the mouse, so longer entries stay reachable.

Use cases
Cooperative survival
Players fighting alongside a group can swing wide without hurting companions who wander into the strike.
Who it’s for: Players who run a team or pet setup in Minecraft and want accidental friendly hits to stop. It suits anyone who plays with others on a shared map, since only the client needs the mod.
