首先重复贴图的图片的宽和高必须是2的n次幂，这里选择一张128*128的小图片来做例子

代码如下：

SizevisibleSize=Director::getInstance()->getVisibleSize();Vec2origin=Director::getInstance()->getVisibleOrigin();autobg=Sprite::create("BackgroundTile.png",Rect(0,0,visibleSize.width,visibleSize.height));Texture2D::TexParamstp={GL_LINEAR,GL_LINEAR,GL_REPEAT,GL_REPEAT};bg->getTexture()->setTexParameters(tp);bg->setPosition(visibleSize.width/2,visibleSize.height/2);this->addChild(bg,0);

运行得到如下效果：
