cocos2dx 怎么画矩形 如何使用cocos2dx画一个矩形，下面就是详细代码
void GameLayer1::draw(void)
{
    CCLayer::draw();
 
    glEnable(GL_LINE_SMOOTH);
    glLineWidth(1);
    CCPoint vertices[] = { ccp(100, 100), ccp(200, 100), ccp(200, 200), ccp(100, 200) };
 
    glDisable(GL_TEXTURE_2D);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);
    glDisableClientState(GL_COLOR_ARRAY);
 
    glColor4ub(255, 0, 0, 255);
    glVertexPointer(2, GL_FLOAT, 0, vertices);
    glDrawArrays(GL_TRIANGLE_FAN, 0, 4);//画填充矩形
 
    glColor4ub(0, 0, 255, 255);
    glVertexPointer(2, GL_FLOAT, 0, vertices);
    glDrawArrays(GL_LINE_LOOP, 0, 4);//画矩形边框
    // restore default state
    glEnableClientState(GL_COLOR_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);
    glEnable(GL_TEXTURE_2D);
}

重写draw函数如上就ok了
