【cocos2d-x 2.x 学习与应用总结】12: cocos2d-x预定义shader源码

Cocos2d-x   发布时间：2022-05-03  发布网站：大佬教程  code.js-code.com
大佬教程收集整理的这篇文章主要介绍了【cocos2d-x 2.x 学习与应用总结】12: cocos2d-x预定义shader源码，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

前言

本文把cocos2d-x 2.x版本中预定义的所有shader源码贴出来，便于集中参考。作者的引擎版本是2.2.3.

下面以ccShaders.h中定义的片段着色器变量名作为标题，逐条列出。(为什么不用顶点着色器的变量名，因为有几个shader只有片段着色器变量名)
