TaCZ:Npcs Unofficial bug fix

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

1. Download and install Forge 1.20.1
2. Drop tacznpcfix-1.20.1.jar into your mods folder alongside tacz_npc.jar
3. Launch the game

Notes

TaCZ:NPC is officially discontinued. The original author recommends checking out [Pillager's Guns (TACZ support) and Insurgents as alternatives. This patch is for those who still want to use TaCZ:NPC despite its discontinued status.

This mod is Issues and PRs are welcome.
