在开发游戏的时候有时候会需要截屏分享，或者保存精彩时刻，需要用到截屏，我自己写了个截屏的插件，里面带有动画和声音，后面我将使用方法也放到下面。下面直接放主代码。

只要将插件里预制体拖到场景里就可以，也可以将上面的脚本放到任意的GameObject上。文章源自大腿Plus-https://www.zhaoshijun.com/archives/437

这个代码我新增了对相机截图的功能，并写了好多重载的方法，用来做任意的截图操作，可对截屏的大小和有无特效效果传入不同的参数。个人对于相机截图比较实用，因为在截取是有些时候不需要UI的时候，可以将UI用一个单独的相机去渲染，其他想要截图的可以用另一个相机渲染，这样在截图的时候就不会把UI也截进去了。文章源自大腿Plus-https://www.zhaoshijun.com/archives/437
