CCLabelBMFont setString导致OpenGL错误0x0500

Question

Cocos2d：OpenGL错误0x0500 CCTextureAtlas.cpp drawNumberOfQuads 686

当我使用setString更新单词时，OpenGL将滚动错误。或者使用单词初始化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
gl.max_texture_size: 4096
gl.max_texture_units: 8
gl.max_samples_allowed: 4
gl.supports_PVRTC: true
gl.supports_NPOT: true
gl.supports_BGRA8888: false
gl.supports_discard_framebuffer: true
gl.supports_vertex_array_object: true

我解决了我的问题。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);
        }
    }
}

}

评论是错误代码。
