生活随笔收集整理的這篇文章主要介紹了 2假动作，数据缓冲，CCEaseExponential,CCEaseElastic,CCEaseBounce,CCCallFunc,funcNCallBack,funcNDCallBack,funcO 小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

1 緩沖動(dòng)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);

??? //看精靈的運(yùn)行速度

??? //man->runAction(in);

??? //man->runAction(out);

??? man->runAction(inOut);

??? addChild(man);

??? return true;

}

//原生繪圖，每一幀都會(huì)繪圖

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);

}

運(yùn)行結(jié)果：

2 并行動(dòng)作和序列動(dòng)作

CCSequence 中持續(xù)時(shí)間為所有動(dòng)作累計(jì)的總合，CCSequence 中不可以

有CCRepeatForever 動(dòng)作。

???CCSpwan中持續(xù)時(shí)間為并行動(dòng)作持續(xù)時(shí)間最長(zhǎng)的決定。

3 假動(dòng)作

???CCCallFunc系列動(dòng)作包括CCallFunc()、CCCallFuncN()、CCCallFuncND,以及CCCallFuncO四個(gè)動(dòng)作，CCCallFunc系列動(dòng)作的后綴”N”表示Node參數(shù)，指的是執(zhí)行動(dòng)作的對(duì)象，”D”表示Data參數(shù)，指的是用戶(hù)自定義的數(shù)據(jù)，”O(jiān)”表示對(duì)象，指的是一個(gè)用戶(hù)自定義的CCObject參數(shù)。在不同的情況下，我們可以根據(jù)不同的需求來(lái)選擇不同的CCCallFunc動(dòng)作。

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

//無(wú)參類(lèi)型

typedef void (CCObject::*SEL_CallFuncN)(CCNode*);

//傳遞CCNode * 類(lèi)型變量

typedef void (CCObject::*SEL_CallFuncND)(CCNode*, void*);

//傳遞CCNode * 類(lèi)型變量，和無(wú)類(lèi)型變量

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

//傳遞CCObject *類(lèi)型變量

#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);
