1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);

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();

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);

//CCEaseBounceOut * out = CCEaseBounceOut::create(by2);

//CCEaseBounceInOut * inOut = CCEaseBounceInOut::create(by2);

//看精灵的运行速度

//原生绘图，每一帧都会绘图

voidT13Action::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);

}

运行结果：

2并行动作和序列动作

CCSequence中持续时间为所有动作累计的总合，CCSequence中不可以

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系列动作包括CCallFunc()、CCCallFuncN()、CCCallFuncND,以及CCCallFuncO四个动作，CCCallFunc系列动作的后缀”N”表示Node参数，指的是执行动作的对象，”D”表示Data参数，指的是用户自定义的数据，”O”表示对象，指的是一个用户自定义的CCObject参数。在不同的情况下，我们可以根据不同的需求来选择不同的CCCallFunc动作。

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

//无参类型

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);
