#include<iostream>#include<cocos2d.h>USING_NS_CC;class ActionCombination :public Layer{public:static Scene* createScene();virtual bool init();void menuCloseCallback(cocos2d::Ref* pSender);CREATE_FUNC(ActionCombination);};

Sequence动作和Spawn动作的区别是前者按顺序执行，后者同时执行多个动作。

#include "ActionCombination.h"Scene* ActionCombination::createScene(){    auto scene = Scene::create();auto layer = ActionCombination::create();scene->addChild(layer);return scene;}bool ActionCombination::init(){if (!Layer::init()){return false;}    Size visibleSize = Director::getInstance()->getVisibleSize();Point origin = Director::getInstance()->getVisibleOrigin();auto closeItem = MenuItemImage::create("CloseNormal.png","CloseSelected.png",CC_CALLBACK_1(ActionCombination::menuCloseCallback, this));closeItem->setPosition(Point(origin.x + visibleSize.width - closeItem->getContentSize().width / 2,origin.y + closeItem->getContentSize().height / 2));auto menu = Menu::create(closeItem, NULL);menu->setPosition(Point::ZERO);this->addChild(menu, 1);    //创建一个精灵在左边，用于测试sequence组合动作auto left = Sprite::create("dance.png");left->setPosition(Point(visibleSize.width / 2 - 200, visibleSize.height / 2));this->addChild(left);//定义第一个RotateTo动作，旋转45度auto rotateTo1 = RotateTo::create(5, 45);//定义第一个RotateTo动作，旋转90度auto rotateTo2 = RotateTo::create(5, 90);//注意，是按顺序执行2个动作left->runAction(Sequence::create(rotateTo1, rotateTo2, NULL));    //右边auto right = Sprite::create("dance.png");right->setPosition(Point(visibleSize.width / 2 + 200, visibleSize.height / 2));auto rotateTo3 = RotateTo::create(5, 45);auto rotateTo4 = RotateTo::create(5, 90);right->runAction(Spawn::create(rotateTo3, rotateTo4, NULL));return true;}void ActionCombination::menuCloseCallback(Ref* pSender){#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8) || (CC_TARGET_PLATFORM == CC_PLATFORM_WINRT)MessageBox("You pressed the close button. Windows Store Apps do not implement a close button.", "Alert");return;#endifDirector::getInstance()->end();#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)exit(0);#endif}
