缓冲动作

man->setScale(0.8f); woman->setScale(0.8f); man->setPosition(ccp(100, 80)); woman->setPosition(ccp(100,240));

CCMoveTo * manTo = CCMoveTo::create(2, ccp(400,80)); CCMoveTo * womanTo = CCMoveTo::create(2, ccp(400, 240)); CCEaseExponentialIn *in = CCEaseExponentialIn::create(manTo); CCEaseExponentialOut *out = CCEaseExponentialOut::create(manTo); CCEaseExponentialInOut * inOut = CCEaseExponentialInOut::create(manTo); man->runAction(inOut); woman->runAction(womanTo);

CCEaseElasticIn *in = CCEaseElasticIn::create(manTo); CCEaseElasticOut *out = CCEaseElasticOut::create(manTo); CCEaseElasticInOut * inOut = CCEaseElasticInOut::create(manTo);

#include "T13Action.h" #include "AppMacros.h" CCScene *T13Action::scene() { CCScene * scene = CCScene::create(); T13Action * layer = T13Action::create(); scene->addChild(layer); return scene; } bool T13Action::init() { TBack::init(); CCSprite * man = CCSprite::create("man.png"); CCSprite * woman = CCSprite::create("woman.png"); man->setPosition(ccp(100, 160)); CCMoveBy *by = CCMoveBy::create(2,ccp(300,0)); CCMoveBy *by2 = CCMoveBy::create(2,ccp(300,0)); CCEaseExponentialIn * in = CCEaseExponentialIn::create(by2); CCEaseExponentialInOut * out = CCEaseExponentialInOut::create(by2); CCEaseExponentialInOut * inOut = CCEaseExponentialInOut::create(by2); //CCEaseElasticIn * in = CCEaseElasticIn::create(by2); //CCEaseElasticOut * out = CCEaseElasticOut::create(by2); //CCEaseElasticInOut * inOut = CCEaseElasticInOut::create(by2); //CCEaseBounceIn *in = CCEaseBounceIn::create(by2); //CCEaseBounceOut * out = CCEaseBounceOut::create(by2); //CCEaseBounceInOut * inOut = CCEaseBounceInOut::create(by2); //看精灵的执行速度 //man->runAction(in); //man->runAction(out); man->runAction(inOut); addChild(man); return true; } //原生画图，每一帧都会画图 void T13Action::draw() { CCPointArray *array = CCPointArray::create(6); array->addControlPoint(ccp(100, 160)); array->addControlPoint(ccp(200, 160)); array->addControlPoint(ccp(200, 250)); array->addControlPoint(ccp(300, 250)); array->addControlPoint(ccp(300, 160)); array->addControlPoint(ccp(450, 160)); ccDrawCardinalSpline(array, 1, 100); }

执行结果：

2
并行动作和序列动作

CCSequence
中持续时间为全部动作累计的总合。CCSequence
中不能够

有CCRepeatForever
动作。

CCSpwan中持续时间为并行动作持续时间最长的决定。

3
假动作

CCCallFunc系列动作包含CCallFunc()、CCCallFuncN()、CCCallFuncND,以及CCCallFuncO四个动作，CCCallFunc系列动作的后缀”N”表示Node參数，指的是运行动作的对象，”D”表示Data參数，指的是用户自己定义的数据。”O”表示对象，指的是一个用户自己定义的CCObject參数。

在不同的情况下。我们能够依据不同的需求来选择不同的CCCallFunc动作。

typedef void (CCObject::*SEL_CallFunc)();

//无參类型 typedef void (CCObject::*SEL_CallFuncN)(CCNode*); //传递CCNode * 类型变量 typedef void (CCObject::*SEL_CallFuncND)(CCNode*, void*); //传递CCNode * 类型变量，和无类型变量 typedef void (CCObject::*SEL_CallFuncO)(CCObject*); //传递CCObject *类型变量 #define callfunc_selector(_SELECTOR) (SEL_CallFunc)(&_SELECTOR) #define callfuncN_selector(_SELECTOR) (SEL_CallFuncN)(&_SELECTOR) #define callfuncND_selector(_SELECTOR) (SEL_CallFuncND)(&_SELECTOR) #define callfuncO_selector(_SELECTOR) (SEL_CallFuncO)(&_SELECTOR)

CCCallFunc * func = CCCallFunc::create(this, callfunc_selector(T13Action::funcCallBack)); CCCallFuncN * func = CCCallFuncN::create(this, callfuncN_selector(T13Action::funcNCallBack)); CCCallFuncND * func = CCCallFuncND::create(this, callfuncND_selector(T13Action::funcNDCallBack), (void *)"30"); CCArray * array = CCArray::create(); array->addObject(woman); CCCallFuncO * func = CCCallFuncO::create(this, callfuncO_selector(T13Action::funcOCallBack),(CCObject*)array); CCSequence * seq = CCSequence::create(to, func, NULL); man->runAction(seq); addChild(man);

案例说明：

无參的假动作 void funcCallBack();

T13Action.h
