大家好，我是佛系工程师☆恬静的小魔龙☆，不定时更新Unity开发技巧，觉得有用记得一键三连哦。

一、前言

在开发中，常常会遇到频繁复制粘贴物体的坐标、旋转、缩放的操作。

使用Unity自带的组件复制粘贴比较麻烦：
复制：

粘贴：

还有一些需要复制位置、旋转、缩放的值到到代码中，如果一个一个复制粘贴非常麻烦，还要一些需要复制添加自定义文本，也很不方便。

所以，就开发了一个小工具，来提升开发效率。

二、正文

2-1、实现快速复制/粘贴，位置/旋转/缩放功能

效果图：

在Editor文件夹中新建脚本，随便命名，然后编辑代码：

}

运行结果：

这样就实现了基本的快速复制/粘贴，位置/旋转/缩放功能。

接下来，就实现单独的位置、旋转、缩放的复制和粘贴吧。

}

演示：

这样就实现了单独的位置/旋转/缩放复制/粘贴功能。

接下来，就实现单独的位置/旋转/缩放复制/粘贴功能以及位置/旋转/缩放一起复制和粘贴功能。

以及，自定义文本拼接的功能。
