cocos2d-x学习记录2——CCAction动作

CCAction能够使CCNode运动起来，能够呈现出多种多样的动作。这些动作能够改变其运动方向、形状、大小、旋转等。

同时，还可利用CCCallFunc、CCCallFuncN、CCCallFuncO、CCCallFuncND等函数实现回调。

MyScene.h代码

 using namespace cocos2d;

 class MyScene : public CCLayer
 {
 public:
     static CCScene* createScene();
     virtual bool init();
     CREATE_FUNC( MyScene );

     void callback1();
     void callback2(CCNode *node);
     void callback3(CCObject *obj);
     void callback4(CCNode *node, void *data);

MyScene.cpp代码

 #include "MyScene.h"

 CCScene* MyScene::createScene()
 {
     CCScene *scene = CCScene::create();
     MyScene *layer = MyScene::create();
     scene->addChild(layer);
     return scene;
 };

 bool MyScene::init()
 {
     if( !CCLayer::init() ){
         return false;
     }

     CCSize size = CCDirector::sharedDirector()->getWinSize();
     CCSprite *sprite = CCSprite::create("pal4.png");
     sprite->setAnchorPoint( ccp(0.5, 0.5) );
     //sprite->setPosition( ccp(size.width/2, size.height/2) );
     sprite->setPosition( ccp(, ) );
     sprite->setScale(0.5f);
     sprite->setTag();
     addChild(sprite);

     CCAction *action1 = CCMoveTo::create(, ccp(size.width-sprite->getContentSize().width/, size.height-sprite->getContentSize().height/));
     CCAction *action2 = CCRotateBy::create(, );
     CCAction *action3 = CCBlink::create(, );
     CCAction *action4 = CCCallFunc::create( this, callfunc_selector(MyScene::callback1) );
     CCAction *action5 = CCCallFuncN::create( this, callfuncN_selector(MyScene::callback2) );
     CCAction *action6 = CCCallFuncO::create( this, callfuncO_selector(MyScene::callback3), sprite );
     CCAction *action7 = CCCallFuncND::create( this, callfuncND_selector(MyScene::callback4), "funcND" );

     CCArray *array = CCArray::createWithCapacity();
     array->addObject(action1);
     array->addObject(action2);
     array->addObject(action3);
     array->addObject(action4);
     array->addObject(action5);
     array->addObject(action6);
     array->addObject(action7);
     //array->addObject(NULL);
     //array->retain();
     //CCAction *totoalAction = CCSequence::create( action1, action2, action3, action4, action5, action6, action7, NULL );
     CCAction *totalAction = CCSequence::create(array);
     sprite->runAction(totalAction);

     return true;
 }

 void MyScene::callback1()
 {
     CCLog( "callback1" );
 }

 void MyScene::callback2(CCNode *node)
 {
     CCLog( "%d", node->getTag() );
 }

 void MyScene::callback3(CCObject *obj)
 {
     CCNode *node = dynamic_cast<CCNode*>(obj);
     if( node != NULL ){
         CCLog( "%d", node->getTag() );
     }
 }

 void MyScene::callback4(CCNode *node, void *data)
 {
     CCLog( "%d, %s", node->getTag(), data );
     CCMessageBox( "Over!", "Info" );
 }

callback1到callback4分别对应4种回调形式，只是各自带的参数不同而已。

运行结果：
