动作执行

CCAction*runAction(CCAction*action)

一、动作类型

1.瞬时动作

CCactionstant- CCPlace			移动到某个位置- CCHIDe/CCShow		<span >	</span>显示或者隐藏- CCToggleVisibility	<span >	</span>反转显示、隐藏（隐藏时运行后显示，显示时运行后隐藏）- CCFlipX/CCFlipY		绕X轴或者Y轴翻转

------------------------------------------------------------------------	CCPlace *place = CCPlace::create(ccp(size.wIDth/2,size.height/2));	pLabel->runAction(place);------------------CCHIDe/CCShow------------------	CCHIDe *hIDe = CCHIDe::create();	pLabel->runAction(hIDe);	CCShow *show = CCShow::create();	pLabel->runAction(show);------------------CCToggleVisibility------------------	CCToggleVisibility *showhIDe1 = CCToggleVisibility::create();	pLabel->runAction(showhIDe1);	CCToggleVisibility *showhIDe2 = CCToggleVisibility::create();	pLabel->runAction(showhIDe2);------------------CCFlipX/CCFlipY------------------	CCFlipX *flipX = CCFlipX::create(true);	pLabel->runAction(flipX);	CCFlipY *flipY = CCFlipY::create(true);	pLabel->runAction(flipY);

2.延时动作

CCActionInterval - CCMoveto/CCMoveBy			移动到（参数）位置/移动到（本身坐标+参数）的位置 - CCJumpTo/CCJumpBy			跳到某个地址（to:目的地址，by相对地址） - CCBezIErTo/CCBezIErBy		按着贝塞尔曲线移动 - CCScaleto/CCScaleBy			to：缩放到多少；by:缩放多少倍 - CCRotateto/CCRotateBy - CCBlink				闪烁 - CCTintTo/CCTintBy			色调变化	注：CCtinitTo不能使用reverse方法。 - CCFadeto				变暗到 - CCFadeIn				淡出 - CCFadeOut				渐隐------------------CCMoveto/CCMoveBy------------------	CCMoveto *moveto = CCMoveto::create(3.0f,ccp(size.wIDth/2,size.height/2+50));	pLabel->runAction(moveto);	CCMoveBy *moveby = CCMoveBy::create(3.0f,ccp(-50,-50));	pLabel->runAction(moveby);------------------CCJumpTo/CCJumpBy------------------	CCJumpTo *jumpto = CCJumpTo::create(3.0f,ccp(size.wIDth,size.height),50,3);	pLabel->runAction(jumpto);	CCJumpBy *jumpby = CCJumpBy::create(3.0f,ccp(50,50),10,5);	pLabel->runAction(jumpby);------------------CCBezIErTo/CCBezIErBy------------------	ccBezIErConfig  bezIErcofig;  	bezIErcofig.controlPoint_1 = ccp(200,300);  	bezIErcofig.controlPoint_2 = ccp( 100,100);  	bezIErcofig.endposition = ccp(100,100);	CCActionInterval  *bezIErby1 = CCBezIErBy::create(3.0f,bezIErcofig);<span >	</span>//原轨迹返回	<span >	</span>CCActionInterval  *bezIErby2 = bezIErby1->reverse();					

<span >	</span>CCAction *actionRe = CCRepeatForever::create(CCSequence::create( bezIErby1,bezIErby2,NulL)); 	pLabel->runAction(actionRe);------------------CCScaleto/CCScaleBy------------------	CCScaleto *scaleto = CCScaleto::create(3.0f,2.0f,2.0f);			pLabel->runAction(scaleto);	CCScaleBy *scaleby = CCScaleBy::create(3.0f,2.0f);	pLabel->runAction(scaleby);------------------CCRotateto/CCRotateBy------------------	CCRotateto *rotateto = CCRotateto::create(3.0f,45.0f,45.0f);	pLabel->runAction(rotateto);	CCRotateBy *rotateby = CCRotateBy::create(3.0f,-45.0f,-45.0f);	pLabel->runAction(rotateby);------------------CCBlink------------------	CCBlink *blink = CCBlink::create(3.0f,5);	pLabel->runAction(blink);------------------CCTintTo/CCTintBy------------------	CCTintTo *tintto = CCTintTo::create(3.0f,255,0);	pLabel->runAction(tintto);	CCTintBy *tintby = CCTintBy::create(3.0f,0);	tintby->reverse();	pLabel->runAction(tintby);------------------CCFadeto------------------	CCFadeto *fadeto = CCFadeto::create(3.0f,100);	pLabel->runAction(fadeto);	CCFadeIn *fadein = CCFadeIn::create(3.0f);	pLabel->runAction(fadein);------------------CCFadeIn------------------	CCFadeIn *fadein = CCFadeIn::create(3.0f);	pLabel->runAction(fadein);------------------CCFadeOut------------------	CCFadeOut *fadeout = CCFadeOut::create(3.0f);	pLabel->runAction(fadeout);

3.组合动作

- 序列：CCSequence- 同步：CCSpawn- 重复有限次：CCRepeat- 反动作：reverse- 无限重复：CCRepeatForever- 帧动画：CCAnimate------------------CCSequence------------------	CCTintTo *tintto = CCTintTo::create(3.0f,0);	CCFadeOut *fadeout = CCFadeOut::create(3.0f);	CCFiniteTimeAction *sequence = CCSequence::create(tintto,fadeout,NulL);	pLabel->runAction(sequence);------------------CCSpawn------------------	CCTintTo *tintto = CCTintTo::create(3.0f,0);	CCFadeOut *fadeout = CCFadeOut::create(3.0f);	CCFiniteTimeAction *spawn = CCSpawn::create(tintto,NulL);	pLabel->runAction(spawn);------------------CCRepeat------------------	CCFadeOut *fadeout = CCFadeOut::create(3.0f);	CCRepeat *repeat = CCRepeat::create(fadeout,5.0f);	pLabel->runAction(repeat);------------------reverse/CCRepeatForever------------------	ccBezIErConfig  bezIErcofig;  	bezIErcofig.controlPoint_1 = ccp(200,NulL)); 	pLabel->runAction(actionRe);------------------CCAnimate------------------	CCSize size = CCDirector::sharedDirector()->getWinSize();	CCSprite *Google = CCSprite::create("gg01.png");	Google->setposition(ccp(size.wIDth/2,size.height/2));	this->addChild(Google,1);	int framCount = 5;	char str[50] = {0};	CCArray *frameArray = CCArray::create();	for (int i=1; i<=framCount; i++)	{		sprintf(str,"gg0%d.png",i);		CCSpriteFrame *frame = CCSpriteFrame::create(str,CCRectMake(0,320,533));		frameArray->addobject(frame);	}	CCAnimation *animation = CCAnimation::createWithSpriteFrames(frameArray,0.2f);<span >	</span>frameArray->release();	CCAnimate *animate = CCAnimate::create(animation);	Google->runAction(CCRepeatForever::create(animate));

4.速度变换

- CCEaseIn	<span >	</span>又慢到快（速度线性变换）- CCEaSEOut <span >		</span>又快到慢- CCEaseSineInOut <span >	</span>由慢至快再由快至慢- CCeaseSineIn	  <span >	</span>由慢至快（速度正弦变换）- CCEaseSineOut <span >	</span>由快至慢（速度正弦变换）- CCEaseSineInOut<span >	</span>由慢至快再由快至慢- CCEaseExponentialin <span >	</span>由慢至极快（速度指数级变换）- CCEaseExponentialOut<span >	</span>由快至极慢（速度指数级变换）- CCEaseExponentialinOut 由慢至极快再由快至极慢- CCSpeed 人工设定速度，通过setSpeed不断调整参考代码：tests->ActionsEaseTest-------------------CCEaseIn/CCEaSEOut -------------------#define CCCA(x)   (x->copy()->autorelease())voID SpriteEase::onEnter(){    EaseSpriteDemo::onEnter();        CCActionInterval* move = CCMoveBy::create(3,ccp(VisibleRect::right().x-130,0));    CCActionInterval* move_back = move->reverse();        CCActionInterval* move_ease_in = CCEaseIn::create((CCActionInterval*)(move->copy()->autorelease()),2.5f);    CCActionInterval* move_ease_in_back = move_ease_in->reverse();        CCActionInterval* move_ease_out = CCEaSEOut::create((CCActionInterval*)(move->copy()->autorelease()),2.5f);    CCActionInterval* move_ease_out_back = move_ease_out->reverse();        CCDelayTime *delay = CCDelayTime::create(0.25f);        CCSequence* seq1 = CCSequence::create(move,delay,move_back,CCCA(delay),NulL);    CCSequence* seq2 = CCSequence::create(move_ease_in,move_ease_in_back,NulL);    CCSequence* seq3 = CCSequence::create(move_ease_out,move_ease_out_back,NulL);            CCAction *a2 = m_grossini->runAction(CCRepeatForever::create(seq1));    a2->setTag(1);    CCAction *a1 = m_tamara->runAction(CCRepeatForever::create(seq2));    a1->setTag(1);    CCAction *a = m_kathia->runAction(CCRepeatForever::create(seq3));    a->setTag(1);    schedule(schedule_selector(SpriteEase::testStopAction),6.25f);}voID SpriteEase::testStopAction(float dt){    unschedule(schedule_selector(SpriteEase::testStopAction));    m_tamara->stopActionByTag(1);    m_kathia->stopActionByTag(1);    m_grossini->stopActionByTag(1);}-------------------CCSpeed-------------------voID SpeedTest::onEnter(){    EaseSpriteDemo::onEnter();        CCSize s = CCDirector::sharedDirector()->getWinSize();    // rotate and jump    CCActionInterval *jump1 = CCJumpBy::create(4,ccp(-s.wIDth+80,0),100,4);    CCActionInterval *jump2 = jump1->reverse();    CCActionInterval *rot1 = CCRotateBy::create(4,360*2);    CCActionInterval *rot2 = rot1->reverse();        CCSequence* seq3_1 = CCSequence::create(jump2,jump1,NulL);    CCSequence* seq3_2 = CCSequence::create( rot1,rot2,NulL);    CCSpawn* spawn = CCSpawn::create(seq3_1,seq3_2,NulL);    //创建速度可改变的动画    CCSpeed* action = CCSpeed::create(CCRepeatForever::create(spawn),1.0f);    action->setTag(kTagAction1);        CCAction* action2 = (CCAction*)(action->copy()->autorelease());    CCAction* action3 = (CCAction*)(action->copy()->autorelease());    action2->setTag(kTagAction1);    action3->setTag(kTagAction1);        m_grossini->runAction(action2);    m_tamara->runAction(action3);    m_kathia->runAction(action);        this->schedule(schedule_selector(SpeedTest::altertime),1.0f);//:@selector(altertime:) interval:1.0f];}voID SpeedTest::altertime(float dt){        CCSpeed* action1 = (CCSpeed*)(m_grossini->getActionByTag(kTagAction1));    CCSpeed* action2 = (CCSpeed*)(m_tamara->getActionByTag(kTagAction1));    CCSpeed* action3 = (CCSpeed*)(m_kathia->getActionByTag(kTagAction1));        //设置随机动画速度    action1->setSpeed( CCRANDOM_MINUS1_1() * 2 );    action2->setSpeed( CCRANDOM_MINUS1_1() * 2 );    action3->setSpeed( CCRANDOM_MINUS1_1() * 2 );}

二、扩展动作

延时： - CCDelayTime函数调用： - CCCallFunc（无参） - CCCallFuncN（当前对象CCNode） - CCCallfuncND(当前对象，VoID指针)-------------------函数调用-------------------voID ActionCallFunc::onEnter(){    ActionsDemo::onEnter();    centerSprites(3);//执行完动画后调用函数    CCFiniteTimeAction*  action = CCSequence::create(        CCMoveBy::create(2,ccp(200,0)),CCCallFunc::create(this,callfunc_selector(ActionCallFunc::callback1)),NulL);    CCFiniteTimeAction*  action2 = CCSequence::create(        CCScaleBy::create(2,2),CCFadeOut::create(2),CCCallFuncN::create(this,callfuncN_selector(ActionSequence2::callback2)),NulL);    CCFiniteTimeAction*  action3 = CCSequence::create(        CCRotateBy::create(3,360),CCCallFuncND::create(this,callfuncND_selector(ActionSequence2::callback3),(voID*)0xbebabeba),NulL);    m_grossini->runAction(action);    m_tamara->runAction(action2);    m_kathia->runAction(action3);}voID ActionCallFunc::callback1(){    CCSize s = CCDirector::sharedDirector()->getWinSize();    cclabelTTF *label = cclabelTTF::create("callback 1 called","Marker Felt",16);    label->setposition(ccp( s.wIDth/4*1,s.height/2));    addChild(label);}voID ActionCallFunc::callback2(CCNode* pSender){    CCSize s = CCDirector::sharedDirector()->getWinSize();    cclabelTTF *label = cclabelTTF::create("callback 2 called",16);    label->setposition(ccp( s.wIDth/4*2,s.height/2));    addChild(label);}voID ActionCallFunc::callback3(CCNode* pTarget,voID* data){    CCSize s = CCDirector::sharedDirector()->getWinSize();    cclabelTTF *label = cclabelTTF::create("callback 3 called",16);    label->setposition(ccp( s.wIDth/4*3,s.height/2));    addChild(label);}

三、动作管理器（ActionManager）

维护一个动作表（hash表） CCAction * CCNode::runAction(CCAction* action){    CCAssert( action != NulL,"Argument must be non-nil");    m_pActionManager->addAction(action,this,!m_bRunning);    return action;}利用动作管理器暂停动作，因为动作管理器是全局的，这样就避免第一个类要停止第二个类中的动作需要传递参数的麻烦。    CCDirector* pDirector = CCDirector::sharedDirector();    pDirector->getActionManager()->pauseTarget(pGrossini);    pGrossini->runAction(CCRotateBy::create(2,360));

===================================================================

总结：

动画在游戏中占据着举足轻重的位置，必须拿下。

开心一刻：

上农艺课时，老师提问：“什么时候摘西瓜最合适？”一个学生不假思索地回答：“在看瓜人睡熟了的时候。”
