【Cocos2d-x游戏引擎开发笔记(5)】自定义动画

原创文章，转载请注明出处：/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。

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：

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：

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;
}
