我最终使用了 GL_SCISSOR.

I ended up using GL_SCISSOR.

在我实现的 MainSprite 中:

in MainSprite I impemented:

- (void) visit
{
    if (!self.visible) {
        return;
    }
    glEnable(GL_SCISSOR_TEST);
    glScissor(x, y, width, height);   
    [super visit];
    glDisable(GL_SCISSOR_TEST);
}

这将剪切或遮盖指定区域.

This will clip or mask the specified area.

唯一棘手的一点是，在横向模式下，Cocos2D 在屏幕的左下角有 0,0，而 OpenGL 在右下角有它，因为它不考虑屏幕的方向.

The only tricky bit is that in Landscape mode Cocos2D has 0,0 at the bottom-left side of the screen, while OpenGL has it at the bottom-right corner as it doesn't consider the orientation of the screen.

换句话说，对于 OpenGL，假设您有一个旋转的纵向屏幕.

In other words, for OpenGL consider you have a rotated portrait Screen.
