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);

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);

 

    //看精灵的运行速度

    //man->runAction(in);

    //man->runAction(out);

    man->runAction(inOut);

 

    addChild(man);

    return true;

}

 

//原生绘图,每一帧都会绘图

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);

}

运行结果:

bubuko.com,布布扣

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

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);

案例说明:

无参的假动作

void funcCallBack();

T13Action.h

#ifndef _T13Action_H__

#define _T13Action_H__

#include "cocos2d.h"

#include "TBack.h"

USING_NS_CC;

class T13Action :public TBack

{

public:

    static CCScene * scene();

    CREATE_FUNC(T13Action);

    bool init();

 

    void draw();

 

    //无参的假动作

    void funcCallBack();

    //带调用者的假动作

    void funcNCallBack(CCNode * node);

    //带有调用者和数据的假动作

    void funcNDCallBack(CCNode * node, void * data);

    //带有对象的假动作

    void funcOCallBack(CCObject * obj);

};

 

#endif

T13Action.cpp

#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 *by2 = CCMoveBy::create(2, ccp(300, 0));

    //假动作就是当一个动作执行完了之后又执行的一个动作

    CCCallFunc * func = CCCallFunc::create(this,callfunc_selector(T13Action::funcCallBack));

    CCSequence * seq = CCSequence::create(by2, func, NULL);

 

    man->runAction(seq);

    addChild(man);

    return true;

}

 

//原生绘图,每一帧都会绘图

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);

}

 

//无参的假动作

void T13Action::funcCallBack() {

    CCLog("action is over");

}

运行结果(运行速度是变速的):

bubuko.com,布布扣

输出结果:
