【Cocos2d-x游戏引擎开发笔记(5)】自定义动画

转载自：/article/1389517.html

上篇中实现的是Cocos2d-x提供给我们的动画，这次要实现的动画是自定义的动画。

这次实现的是让一个精灵一直执行我给的图片，从而达到动画的效果，还是截几张图看看。






图片资源来自解压《捕鱼达人》和《魔塔》





























一共有18张图片。

[cpp] view
plaincopy

CCTexture2D *pTexture=CCTextureCache::sharedTextureCache()->addImage("hero.png");

CCSpriteFrame *frame0=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,0,32,32));

CCSpriteFrame *frame1=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(32,0,32,32));

CCSpriteFrame *frame2=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(64,0,32,32));

CCSpriteFrame *frame3=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(96,0,32,32));

CCArray *animFrames=CCArray::create();

CC_BREAK_IF(!animFrames);

animFrames->addObject(frame0);

animFrames->addObject(frame1);

animFrames->addObject(frame2);

animFrames->addObject(frame3);

CCAnimation *animation=CCAnimation::createWithSpriteFrames(animFrames,0.2f);

CC_BREAK_IF(!animation);

CCSprite *heroSprite0=CCSprite::createWithSpriteFrame(frame0);

CC_BREAK_IF(!heroSprite0);

heroSprite0->setPosition(ccp(100,100));

addChild(heroSprite0,1);

CCAnimate *animate=CCAnimate::create(animation);

heroSprite0->runAction(CCRepeatForever::create(animate));//一直执行下去

上面的动画是使英雄一直执行走动下去。

还有另外的一种方法来实现自定义动画：

[cpp] view
plaincopy

CCAnimation* animation2 = CCAnimation::create();

for(int i=1;i<19;i++)

{

char *tt=new char[3];

memset(tt,0,3);

std::string s;

if(i<10)

{

itoa(i,tt,10);

s="fish00"+std::string(tt);

}

else

{

itoa(i,tt,10);

s="fish0"+std::string(tt);

}

s=s+".png";

CCTexture2D *playerRunTexture = CCTextureCache::sharedTextureCache()->addImage(s.c_str());

animation2->addSpriteFrame(CCSpriteFrame::createWithTexture(playerRunTexture, cocos2d::CCRectMake(0, 0, 100, 100)));

delete []tt;

}

animation2->setDelayPerUnit(0.2f);

CCAnimate* action = CCAnimate::create(animation2);

CCTexture2D *playerRunTexture0 = CCTextureCache::sharedTextureCache()->addImage("fish001.png");

CCSprite *p=CCSprite::createWithSpriteFrame(CCSpriteFrame::createWithTexture(playerRunTexture0, cocos2d::CCRectMake(0, 0, 100, 100)));

p->setPosition(ccp(200,200));

addChild(p,1);

p->runAction(CCRepeatForever::create(action));

代码是如此的简单，我就不多说了。

最后照例贴出init函数的全部代码：

[cpp] view
plaincopy

bool HelloWorld::init()

{

mPercentage=100;

bool bRet = false;

do

{

CC_BREAK_IF(! CCLayer::init());

CCTexture2D *pTexture=CCTextureCache::sharedTextureCache()->addImage("hero.png");

CCSpriteFrame *frame0=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,0,32,32));

CCSpriteFrame *frame1=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(32,0,32,32));

CCSpriteFrame *frame2=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(64,0,32,32));

CCSpriteFrame *frame3=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(96,0,32,32));

CCArray *animFrames=CCArray::create();

CC_BREAK_IF(!animFrames);

animFrames->addObject(frame0);

animFrames->addObject(frame1);

animFrames->addObject(frame2);

animFrames->addObject(frame3);

CCAnimation *animation=CCAnimation::createWithSpriteFrames(animFrames,0.2f);

CC_BREAK_IF(!animation);

CCSprite *heroSprite0=CCSprite::createWithSpriteFrame(frame0);

CC_BREAK_IF(!heroSprite0);

heroSprite0->setPosition(ccp(100,100));

addChild(heroSprite0,1);

CCAnimate *animate=CCAnimate::create(animation);

heroSprite0->runAction(CCRepeatForever::create(animate));//一直执行下去

CCActionInterval *en=CCRotateBy::create(5,-360);

CCSprite *hua=CCSprite::create("end.png");

hua->setPosition(ccp(240,160));

addChild(hua,1);

hua->runAction(CCRepeatForever::create(en));

CCAnimation* animation2 = CCAnimation::create();

for(int i=1;i<19;i++)

{

char *tt=new char[3];

memset(tt,0,3);

std::string s;

if(i<10)

{

itoa(i,tt,10);

s="fish00"+std::string(tt);

}

else

{

itoa(i,tt,10);

s="fish0"+std::string(tt);

}

s=s+".png";

CCTexture2D *playerRunTexture = CCTextureCache::sharedTextureCache()->addImage(s.c_str());

animation2->addSpriteFrame(CCSpriteFrame::createWithTexture(playerRunTexture, cocos2d::CCRectMake(0, 0, 100, 100)));

delete []tt;

}

animation2->setDelayPerUnit(0.2f);

CCAnimate* action = CCAnimate::create(animation2);

CCTexture2D *playerRunTexture0 = CCTextureCache::sharedTextureCache()->addImage("fish001.png");

CCSprite *p=CCSprite::createWithSpriteFrame(CCSpriteFrame::createWithTexture(playerRunTexture0, cocos2d::CCRectMake(0, 0, 100, 100)));

p->setPosition(ccp(200,200));

addChild(p,1);

p->runAction(CCRepeatForever::create(action));

bRet = true;

} while (0);

return bRet;

}
