命令行新建一个工程

cocos new ActionGame -p com.MyCompany.ActionGame -l cpp -d ./MyCompany

新建一个名叫ActionGame的项目，目录在当前目录的MyCompany目录下

使用gedit打开HelloWorldScene.cpp

去掉一些不要的代码，比如显示hello world的字符串等,下面的双斜线的注释为去掉的代码。

准备图片，来源于网络，这些图片规定每个鱼儿的位置，所以应该是顺序排列。

源码：

// on "init" you need to initialize your instancebool HelloWorld::init(){    //////////////////////////////    // 1. super init first    if ( !Layer::init() )    {        return false;    }        auto visibleSize = Director::getInstance()->getVisibleSize();    Vec2 origin = Director::getInstance()->getVisibleOrigin();    /////////////////////////////    // 2. add a menu item with "X" image, which is clicked to quit the program    //    you may modify it.    // add a "close" icon to exit the progress. it's an autorelease object    // auto closeItem = MenuItemImage::create("CloseNormal.png", "CloseSelected.png", CC_CALLBACK_1(HelloWorld::menuCloseCallback, this));        // closeItem->setPosition(Vec2(origin.x + visibleSize.width - closeItem->getContentSize().width/2 , origin.y + closeItem->getContentSize().height/2));    // create menu, it's an autorelease object    // auto menu = Menu::create(closeItem, NULL);    // menu->setPosition(Vec2::ZERO);    // this->addChild(menu, 1);    /////////////////////////////    // 3. add your codes below...    // add a label shows "Hello World"    // create and initialize a label        // auto label = Label::createWithTTF("Hello World", "fonts/Marker Felt.ttf", 24);        // position the label on the center of the screen    // label->setPosition(Vec2(origin.x + visibleSize.width/2, origin.y + visibleSize.height - label->getContentSize().height));    // add the label as a child to this layer    // this->addChild(label, 1);    // add "HelloWorld" splash screen"    // auto sprite = Sprite::create("HelloWorld.png");    // position the sprite on the center of the screen    // sprite->setPosition(Vec2(visibleSize.width/2 + origin.x, visibleSize.height/2 + origin.y));    // add the sprite as a child to this layer    // this->addChild(sprite, 0);    auto mySprite = Sprite::create("mysprite.png");this->addChild(mySprite);mySprite->setPosition(Vec2(visibleSize.width/2 + origin.x, visibleSize.height/2 + origin.y));// now lets animate the sprite we movedVector<SpriteFrame *> animFrames;animFrames.reserve(12);animFrames.pushBack(SpriteFrame::create("Blue_Front1.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Front2.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Front3.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Left1.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Left2.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Left3.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Back1.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Back2.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Back3.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Right1.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Right2.png", Rect(0, 0, 100, 100)));animFrames.pushBack(SpriteFrame::create("Blue_Right3.png", Rect(0, 0, 100, 100)));// create the animation out of the framesAnimation* animation = Animation::createWithSpriteFrames(animFrames, 0.1f);Animate* animate = Animate::create(animation);mySprite->runAction(RepeatForever::create(animate));    return true;}

编译生成apk

cocos compile -s ./MyCompany/ActionGame -p android -m debug -o ./MyCompany/ActionGame/bin

安装进入手机

adb install MyCompany/ActionGame/bin/ActionGame-debug.apk

运行效果，显示为动画，截取某个图片。
