Unity 编辑器开发实战【Editor Window】

Unity 编辑器开发实战【Editor Window】

1.Name Duplicator：名称复制机（根据层级结构复制名称）

2.Material Duplicator：材质复制机（根据层级结构复制材质）

代码如下：

namespace SK.Framework
{public interface IDuplicator{string InvalidatedInfo { get; }bool IsValidated();void Duplicate();}
}

namespace SK.Framework
{public abstract class AbstractDuplicator<T> : IDuplicator{public virtual string InvalidatedInfo{get{return "Is invalidated.";}}protected T from;protected T to;public abstract bool IsValidated();public abstract void Duplicate();}
}

}
