CCLabelBMFont设置字符串导致OpenGL错误0x0500

Cocos2d:OpenGL错误0x0500 CCTextureAtlas.cpp drawNumberOfQuads 686

当我用setString更新word时，OpenGL将出现滚动错误。或者用文字来初始化CCLabelBMFont

cocos2d.x.version: cocos2d-x 2.2.6
cocos2d.x.compiled_with_profiler: false
cocos2d.x.compiled_with_gl_state_cache: true
gl.vendor: Apple Inc.
gl.renderer: Apple A8 GPU
gl.version: OpenGL ES 2.0 Apple A8 GPU - 50.6.10

我解决我的问题。这不是cocos2dx问题

池代码原因：

void Box2dCCSprite::setOpacity(GLubyte opacity){
super::setOpacity(opacity);
if (m_pChildren) {
    for (int i=m_pChildren->count()-1; i>=0; i--) {
        CCSprite* child = dynamic_cast<CCSprite*>(m_pChildren->objectAtIndex(i));
        //CCSprite* child=(CCSprite*)m_pChildren->objectAtIndex(i);
        if (child) {
            child->setOpacity(opacity);
        }
    }
}

}

注释是错误代码。

请粘贴代码好吗？这会更容易理解。@shaqirsaiyed thx，我终于纠正了错误。@shaqirsaiyed实际上并不是所有的子项都是CCSpriteohwkey，所以您只想为那些是ccsprite的子项设置不透明度，对吧@沙基尔说是的
