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:

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

在Editor文件夹中新建脚本,随便命名,然后编辑代码:

using UnityEditor;

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。
