http://www.cocos2d-x.org/forums/6/topics/49035?r=49104 我按这个网页上的要求做的，结果图片是灰了，但偏了很多，求大神帮忙解决一下。。。
我的版本是cocos2dx-3.0 稳定版。。。
请问你解决了吗？我也用这个方式来置灰，也是偏移了，好囧
已解决，顶点着色器里面的MVP矩阵改成P矩阵就可以了,ccShader_PositionTextureColor_noMVP.vert 这个东西
…我找到了这个东西…怎么改啊 大大
const char* ccPositionTextureColor_noMVP_vert = STRINGIFY(
attribute vec4 a_position;
attribute vec2 a_texCoord;
attribute vec4 a_color;
\n#ifdef GL_ES\n
varying lowp vec4 v_fragmentColor;
varying mediump vec2 v_texCoord;
\n#else\n
varying vec4 v_fragmentColor;
varying vec2 v_texCoord;
\n#endif\n
void main()
{
gl_Position = CC_PMatrix * a_position;
v_fragmentColor = a_color;
v_texCoord = a_texCoord;
}
);
那把 MVP矩阵换了 别的功能不影响吗？？ 有别的方法吗？ 还有怎么改的 能告诉的详细点吗？
锚点问题 sprite->setAnchorPoint(Point(0.5, 0.5)); 改为 (Point(0,0)) 就可以了

试验了一下 锚点变换了 也不好用啊
我用的是3.2的版本 位置还是偏 不过图片确实变灰了
坐标变化的解决了，将附件gray.vsh 中的CC_MVPMatrix 改为 CC_PMatrix 即可
怎么让变灰的精灵变回来呀
楼主，貌似不能文件不能下载了，能提供下文件吗？非常感谢了。
