About this project
What does PathEngine add?
Description (English)
PathEngine is a lightweight library mod that provides a from-scratch, asynchronous A* pathfinding engine: graph search, terrain queries, and a block-state snapshot cache, built to run without blocking the main game thread.
It supports diagonal movement, step-up/climbing, bridging (placing blocks mid-air to cross gaps), swimming/underwater movement, mining-route construction (including wedge-escape when stuck in corners), and detects unreachable goals with a cooldown to avoid repeated pathing requests.
This mod does nothing by itself. It exists solely as a required dependency for AutonomeNPC, which uses it to move its companion NPCs.
Requirements
- Minecraft 1.21.1 / NeoForge 21.1.x / Java 21
- No configuration needed — install alongside AutonomeNPC

説明文（日本語）
PathEngine は、スクラッチ実装の非同期A*経路探索エンジンを提供する軽量ライブラリMODです。グラフ探索・地形クエリ・ブロックステートのスナップショットキャッシュを備え、メインスレッドを止めずに動作するよう設計されています。
平面の斜め移動、段差登り、橋渡し（空中への足場設置による隙間越え）、遊泳・水中移動、採掘ルート構築（角に詰まった際のwedge脱出を含む）に対応し、到達不能なゴールをクールダウン付きで検出して無限に経路要求を繰り返さないようにします。
このMOD単体では何も起こりません。 AutonomeNPC がコンパニオンNPCの移動処理に利用するための必須依存として存在します。
動作環境
- Minecraft 1.21.1 / NeoForge 21.1.x / Java 21
- 設定不要。AutonomeNPCと同時に導入するだけ
