说明：除了实现 UnLuaInterface 的静态绑定方式外，还可以在运行时动态绑定对象到Lua

对于 Actor 类，可以使用 SpawnActor 接口，例如：

World:SpawnActor(SpawnClass, Transform, AlwaysSpawn, self, self, "Tutorials.GravitySphereActor")

对于非 Actor 类，可以使用 NewObject 接口，例如：

NewObject(WidgetClass, self, nil, "Tutorials.IconWidget")

注意：无论哪种绑定方式，都需要指定脚本文件路径。它是一个相对于 {工程目录}/Content/Script 下的相对路径。
