前一篇教程，把項目中道具系統用到的很多東全揉搓在一起，要說明的很多，但東西實在太多，沒辦法一一道來。

現在我們就單獨的來看看coco2d中動畫的的基本實現。

利用上一篇教程中“定時炸彈”的動畫來說明吧，先上資源圖：

然後上代碼：

bool Daoju::ZhadanAnimate(float zx, float zy){
	CCLog("Animate");
	CCTexture2D *texture = CCTextureCache::sharedTextureCache()->addImage("Zhadan.png");
	//加載資源（圖片起點_左上角，圖片大小）
	  //讀取資源中的每一幀，暫存到fram
	CCSpriteFrame *frame0 = CCSpriteFrame::frameWithTexture(texture, CCRectMake(16*0, 16*0, 16, 16));
	CCSpriteFrame *frame1 = CCSpriteFrame::frameWithTexture(texture, CCRectMake(16*1, 16*0, 16, 16));
	CCSpriteFrame *frame2 = CCSpriteFrame::frameWithTexture(texture, CCRectMake(16*0, 16*1, 16, 16));
	CCSpriteFrame *frame3 = CCSpriteFrame::frameWithTexture(texture, CCRectMake(16*1, 16*1, 16, 16));
	CCSpriteFrame *frame4 = CCSpriteFrame::frameWithTexture(texture, CCRectMake(16*0, 16*2, 16, 16));
	CCSpriteFrame *frame5 = CCSpriteFrame::frameWithTexture(texture, CCRectMake(16*1, 16*2, 16, 16));
	CCSpriteFrame *frame6 = CCSpriteFrame::frameWithTexture(texture, CCRectMake(16*0, 16*3, 16, 16));
	CCSpriteFrame *frame7 = CCSpriteFrame::frameWithTexture(texture, CCRectMake(16*1, 16*3, 16, 16));
	//設置初始圖片(第一幀)
	CCSprite* spZhadananim = CCSprite::spriteWithSpriteFrame(frame0);
	spZhadananim->setPosition(ccp(zx, zy));
	addChild(spZhadananim, 0, 200);//加到相應圖層，設置標籤爲200，我們在回調函數中會利用標籤找到對應的精靈，然後刪除動畫精靈

	//合成動畫-炸彈等待
	CCMutableArray<CCSpriteFrame*> *animZhadanWaitFrames = new CCMutableArray<CCSpriteFrame*>(4);
	//animZhadanWaitFrames->addObject(frame0);
	//animZhadanWaitFrames->addObject(frame1);
	//animZhadanWaitFrames->addObject(frame2);
	//animZhadanWaitFrames->addObject(frame3);
	animZhadanWaitFrames->addObject(frame4);
	animZhadanWaitFrames->addObject(frame5);
	animZhadanWaitFrames->addObject(frame6);
	animZhadanWaitFrames->addObject(frame7);
	//合成動畫-炸彈爆炸
	CCMutableArray<CCSpriteFrame*> *animZhadanExciteFrames = new CCMutableArray<CCSpriteFrame*>(4);
	animZhadanExciteFrames->addObject(frame0);
	animZhadanExciteFrames->addObject(frame1);
	animZhadanExciteFrames->addObject(frame2);
	animZhadanExciteFrames->addObject(frame3);

	
	//將4個動畫偵生成CCAnimation對象,每0.1秒(float)播放一幀
	//生成炸彈等待動畫
	CCAnimation *animationWait  = CCAnimation::animationWithFrames(animZhadanWaitFrames, 0.1f);
	CCAnimate *animateWait = CCAnimate::actionWithAnimation(animationWait, false);//動畫模版生成動畫

	//生成炸彈激發動畫
	CCAnimation *animationExcit  = CCAnimation::animationWithFrames(animZhadanExciteFrames, 0.2f);
	CCAnimate *animateExcit = CCAnimate::actionWithAnimation(animationExcit, false);//此處值爲false動畫播放完是在最後一幀，爲true則返回第一幀

	//創建回調Action
	CCCallFunc *animOverCallBack = CCCallFunc::actionWithTarget(this, callfunc_selector(Daoju::animBombsOverCallBack));
	//依次執行Action
	spZhadananim->runAction(CCSequence::actions(
		CCRepeat::actionWithAction( animateWait, 12),//第一段動畫重複12次
		//CCDelayTime::actionWithDuration(0.001f), //暫停瞬間一般情況下不用
		CCRepeat::actionWithAction( animateExcit, 1), //第二段動畫重複1次
		animOverCallBack,//回調函數，用於清屏，清除動畫，否則動畫播放玩後屏幕會殘留在屏幕上（對應上面的值可能是最後一幀也可能是第一幀）
		NULL
	));

	animZhadanWaitFrames->release();//釋放資源
	animZhadanExciteFrames->release();
	return true;
}

未完待續。。
