C#下Lua编程支持

xLua为Unity、 .Net、 Mono等C#环境增加Lua脚本编程的能力,借助xLua,这些Lua代码可以方便的和C#相互调用。

xLua的突破

xLua在功能、性能、易用性都有不少突破,这几方面分别最具代表性的是:

  • 可以运行时把C#实现(方法,操作符,属性,事件等等)替换成lua实现;
  • 出色的GC优化,自定义struct,枚举在Lua和C#间传递无C# gc alloc;
  • 编辑器下无需生成代码,开发更轻量;

更详细的特性、平台支持介绍请看这里

安装

打开zip包,你会看到一个Assets目录,这目录就对应Unity工程的Assets目录,保持这目录结构放到你的Unity工程。

如果希望安装到其它目录,请看FAQ相关介绍。

文档

快速入门

一个完整的例子仅需3行代码:

安装好xLua,建一个MonoBehaviour拖到场景,在Start加入如下代码:

XLua.LuaEnv luaenv = new XLua.LuaEnv();
luaenv.DoString("CS.UnityEngine.Debug.Log('hello world')");
luaenv.Dispose();

1、DoString参数为string,可输入任意合法的Lua代码,本示例在lua里调用C#的UnityEngine.Debug.Log打印了个日志。

2、一个LuaEnv实例对应Lua虚拟机,出于开销的考虑,建议全局唯一。

C#主动调用lua也很简单,比如要调用lua的系统函数,推荐方式是:

  • 声明
[XLua.CSharpCallLua]
public delegate double LuaMax(double a, double b);
  • 绑定
var max = luaenv.Global.GetInPath<LuaMax>("math.max");
  • 调用
Debug.Log("max:" + max(32, 12));

建议绑定一次,重复使用。生成了代码的话,调用max是不产生gc alloc的。

热补丁

  • 侵入性小,老项目原有代码不做任何调整就可使用。
  • 运行时影响小,不打补丁基本和原有程序一样。
  • 出问题了可以用Lua来打补丁,这时才会走到lua代码逻辑;

这里是使用指南。
