TaCZ NPC Fix

An unofficial patch for TaCZ:NPC that fixes NullPointerException crashes.

What does this mod do?

TaCZ:NPC adds gun-wielding NPCs to your world — but the mod has been discontinued and contains a critical bug: when an NPC locks onto a target and that target dies, the game crashes with a NullPointerException.

This mod applies a Mixin patch to fix that crash without modifying TaCZ:NPC itself.

Fixes applied:

TaczShootAttack#tick() — cancels the tick if the lock-on target is null, dead, or removed
TaczShootAttack#stop() — clears the target reference when the behavior stops, preventing stale references from persisting

Requirements

Minecraft 1.20.1
Forge 47.x
[TaCZ:NPC](this mod does nothing without it)
[TACZ (Timeless and Classics Zero)]

Installation

Download and install Forge 1.20.1
Drop tacznpcfix-1.20.1.jar into your mods folder alongside tacz_npc.jar

Notes
