GitHub - micropu/JEngine: The solution that allows unity games to update in runtime. 使Unity开发的游戏支持热更新的解决方案。

Why JEngine

A handful of files — that's the entire core package. Drop it in and hot updates just work. No boilerplate code required.

HybridCLR runs standard C# natively — 10x+ faster than ILRuntime or Lua. UniTask for GC-free async, Nino for zero-allocation serialization.

Encrypt assets and DLLs with XOR, AES, or ChaCha20. Obfuscate hot update code with Obfuz. No other hot update framework ships this.

Compile code, generate AOT metadata, obfuscate, encrypt, and package resources — all from one button in the JEngine Panel.

iOS, Android, Windows, macOS, WebGL — plus WeChat, Douyin, Alipay, and TapTap mini-game platforms. YooAsset powers games with 1M+ DAU.

First hot update framework with a Claude Code plugin. AI that understands JEngine patterns and writes idiomatic code for your game.

Traditional Approach	With JEngine
Learn Lua or TypeScript for hot update code	Standard C# — same language, same IDE, same debugging
Register cross-domain adapters (ILRuntime)	Zero adapters — HybridCLR runs C# natively
No built-in asset protection	XOR / AES / ChaCha20 encryption + code obfuscation
Manual multi-step build pipeline	One-click build from JEngine Panel

Unity 2022.3+ required. Follow the Getting Started Guide to be up and running in minutes.

Package	Type	Description
JEngine.Core	Required	Hot update runtime — bootstrap, encryption, resource management
JEngine.Util	Optional	JAction (zero-GC async tasks) · JObjectPool (lock-free object pooling)
JEngine.UI	Optional	MessageBox (async dialog prompts) · Editor UI (modern UI Toolkit components with theming)
