About this project

What does TensuraAiFix add?

TensuraAIFix is a lightweight, server-side performance patch for the That Time I Got Reincarnated as a Slime (Tensura) mod family.
It trims the heaviest AI behaviors that cause pathfinding spikes and tick lag.

What it does

  • Removes Tensura’s heavy PassiveMeleeAttack goal at runtime (the main pathfinding spammer).

 - Keeps combat intact

  • Preserves flying/special AI (skills/abilities are left alone; the mod no longer nukes entire AI selectors).

  • Disables AI for “clone” entities to stop runaway CPU use.

  • Safety sweep every ~2s to re-remove expensive goals if another mod re-adds them.

  • Fixes each mob once (NBT flag + in-memory session cache) to avoid repeat work.

  • Quiet by default: minimal logging and a small “Fixed X mobs” summary ~10s after startup

Results (typical)

  • Smoother TPS during big fights or dense Tensura spawns.

  • Far fewer GroundPathNavigation spikes in spark reports.

  • Mobs still move, target, and attack—just without the pathfinding thrash.

 - This mod does not change spawn rates, damage, drops, or content. It only adjusts AI goals at runtime.

Does it need to run on the client?
A: No. Server-side is enough. Singleplayer is covered via the integrated server.
