Description
Box3JS — Minecraft Scripting Engine
Beta — APIs may change during early development. Feedback is welcome.
No Java, just TypeScript. Build Minecraft minigames, RPG systems, and world mechanics with scripts that hot-reload in seconds.
Built on Mozilla Rhino, Box3JS brings the Box3 coding style to Minecraft servers. Write TypeScript, run it instantly — no JDK, no Gradle, no server restarts.
Features
- TypeScript-first — Full type declarations (
.d.ts) with bilingual JSDoc, auto-complete in any editor - Box3-compatible API — World, Entity, Player, Voxels, Storage, Database, HTTP, remoteChannel
- 110+ Minecraft extensions — Scoreboards, BossBars, teams, world border, particles, fireworks, potions, custom blocks/items/sounds registration, and more
- Client-side scripting — Custom HUD, keyboard input, audio playback, client-side SQLite & HTTP
- Project isolation — Run multiple script projects independently, each with its own scope and callbacks
- Sandbox mode — Test safely; roll back all script-made changes on stop
- Standalone compilation —
/box3script compilepackages your script into a distributable JAR
Quick Start
/box3script create mygamenpm install && npm run build/box3script sandbox mygame

Box3JS（神岛代码）— Minecraft 脚本引擎
Beta — 早期测试阶段，API 可能变动，欢迎反馈。
不写 Java，只用 TypeScript。 在 Minecraft 里用脚本开发小游戏、RPG 玩法、世界机制，热重载秒级生效。
Box3JS 基于 Mozilla Rhino 引擎，延续了神奇代码岛的 API 风格。无需 JDK、无需 Gradle、无需重启服务器，写 TypeScript 即写即跑。
特性
- TypeScript 优先 — 完整类型声明（
.d.ts），双语 JSDoc，任意编辑器均有自动补全 - Box3 兼容 API — World / Entity / Player / Voxels / Storage / Database / HTTP / remoteChannel
- 110+ MC 扩展 — 记分板、Bossbar、队伍、世界边界、粒子、烟花、药水、自定义方块/物品/音效注册等
- 客户端脚本 — 自定义 HUD、键盘输入、音效播放、客户端 SQLite & HTTP
- 项目隔离 — 多脚本项目独立运行，各自拥有独立作用域和回调
- 沙盒模式 — 放心测试，停止后回滚一切脚本改动
- 独立编译 —
/box3script compile一键打包为可分发 JAR
