效果图是这样

Size size = Director::getInstance()->getVisibleSize();//表示获得视口(可视区域)的大小

Vec2 origin = Director::getInstance()->getVisibleOrigin();//表示可视区域的起点坐标

auto* background = Sprite::create("background.jpg");

background->setPosition(size.width / 2, size.height / 2);

background->setScale(0.7f);//让背景图缩小尺寸

addChild(background, 0);

auto* button1 = Sprite::create("button1.png");

button1->setPosition(550, size.height / 2);

button1->setScale(0.6f);

addChild(button1, 1);

auto* pButton2 = MenuItemImage::create("button1.png",//按钮正常状态下图片

"button2.png",//按钮被按下时显示的图片

this,//当前场景

menu_selector(HelloWorld::menu));//响应用户单机的操作

auto* button2 = Menu::create(pButton2, NULL);//创建菜单

button2->setAnchorPoint(Vec2(0,0));

button2->setPosition(550, size.height / 2 - 60);

button2->setScale(0.6f);//缩放

addChild(button2);

auto* pButton3 = MenuItemImage::create("button1.png",

"button2.png",

this,

menu_selector(HelloWorld::menu));

auto* label3 = LabelTTF::create("start", "Arial", 40);//按钮所使用的标签

auto* pLabel3 = MenuItemLabel::create(label3, this, menu_selector(HelloWorld::menu));//创建文字菜单

auto* button3 = Menu::create(pButton3, pLabel3, NULL);//将按钮菜单和文字菜单加入到菜单对象中

button3->setAnchorPoint(Vec2(0, 0));

button3->setPosition(550, size.height / 2 - 120);

button3->setScale(0.6f);

addChild(button3);

auto* renwu = Sprite::create("renwu.png");

renwu->setPosition(0, 0);

renwu->setAnchorPoint(Vec2(0, 0));

renwu->setScale(0.5f);

addChild(renwu, 2);
