记得以前学习XNA游戏开发的时候，操作精灵角色的攻击或者行走动作都是给出特定的几张序列图或者一张长序列图然后通过切割来作一帧一帧的切片动画播放。
开始
关于精灵sprite我从网上摘录了一段话如下
说白一点，精灵就是将图形资源加载到内存中，并根据游戏需要将其显示到屏幕中的工具，游戏中大到背景、UI，小到NPC、道具，只要是用图片展示的，都是精灵或它的子类。从技术上讲，精灵是一个可以不断变化的图片，这些变化包括：位置移动、旋转、缩放、换帧（就是像动画片一样播放几张连续的图片，每帧换一张，形成一个动画效果）
在cocos2d-x 中精灵的关系如下图
精灵多张序列图动画示例
他的三国兵种素材。用到的素材如下
图片命名也是根据nowpaper的示例命名，动画示例代码如下：
CCSize s = CCDirector::sharedDirector()->getWinSize(); //获取界面大小
CCArray *aniframe=CCArray::createWithCapacity( 4); //创建长度为4的集合
CCSprite *sprite;//精灵
char str[
20];
for(
int i=
0;i<
4;i++){
sprintf(str, "
attack/A1_%d.png
",i); //通过下标动态创建精灵
CCSpriteFrame *frame =CCSpriteFrame::create(str,CCRectMake( 0,
0,
64,
64));
if(i==
0){//默认添加第一帧图到界面上
sprite =CCSprite::createWithSpriteFrame(frame);
sprite->setPosition(ccp(sprite->getContentSize().width,s.height/ 2));
addChild(sprite);
}
aniframe->addObject(frame);//将每一帧精灵动画添加到集合里面
}
CCAnimation *animatinotallow=CCAnimation::createWithSpriteFrames(aniframe, 0.2f);//通过集合创建动画
CCAnimate *animate=CCAnimate::create(animation);
CCActionInterval* seq=(CCActionInterval*)(CCSequence::create(animate,
CCFlipX::create( true),
animate->copy()->autorelease(),
CCFlipX::create( false),
NULL
));
sprite->runAction(CCRepeatForever::create(seq));//执行动画
精灵单张序列图动画示例
图片如下
上图序列图是一张序列图，可以看出分为横、竖各4个精灵动画帧，依次分割可以这么分
0-0,0-1,0-2,0-3
1-0,1-1,1-2,1-3
2-0,2-1,2-2,2-3
3-0,3-1,3-2,3-3
分割分部代码为
CCTexture2D *texture=CCTextureCache::sharedTextureCache()->addImage( "
split.png
");
CCArray *splitAniframe=CCArray::createWithCapacity( 16);
CCSprite *splitSprite ;
for(
int i=
0;i<
4;i++){
for(
int j=
0;j<
4;j++)
{
CCSpriteFrame *frame =CCSpriteFrame::createWithTexture(texture,CCRectMake( 32*j,
48*i,
32,
48));
if(i==
0){
splitSprite= CCSprite::createWithSpriteFrame(frame);
splitSprite->setPosition(ccp(s.width/ 2,s.height/
2));
addChild(splitSprite);
}
splitAniframe->addObject(frame);
}
}
CCAnimation *splitAnimatinotallow=CCAnimation::createWithSpriteFrames(splitAniframe, 1.0f);
CCAnimate *splitAnimate=CCAnimate::create(splitAnimation);
splitSprite->runAction(CCRepeatForever::create(splitAnimate));
使用plist的单张序列图的动画
以上两种稍微复杂，cocos2d-x还可以使用一个叫TexturePackerGUI的工具，可以将多张序列图生成一个png的集合图和一个*.plist的文件，工具下载地址：TexturePackGUI
这个工具的使用，网上有很多教的，使用也方便多摸索下就可以了，使用该工具生成后的文件如下：
之后你就可以将它放入内存中操纵了，可能你会发现生成后的图片比之前的几张序列图要小好多，所以为了更快的游戏程序建议多使用该工具，动画代码如下：
CCSpriteFrameCache* cache =CCSpriteFrameCache::sharedSpriteFrameCache();
cache->addSpriteFramesWithFile( " attack.plist
");
CCSprite *plistSprite=CCSprite::createWithSpriteFrameName( " A1_0.png
");
plistSprite->setPosition(ccp(CCDirector::sharedDirector()->getWinSize().width-plistSprite->getContentSize().width,CCDirector::sharedDirector()->getWinSize().height/ 2));
CCSpriteBatchNode* spritebatch =CCSpriteBatchNode::create( " attack.png
");
spritebatch->addChild(plistSprite);
addChild(spritebatch);
CCArray* plistArray=CCArray::createWithCapacity( 4);
char name[ 20];
for( int i=
0;i<
4;i++){
sprintf(name, " A1_%d.png
",i);
CCSpriteFrame* frame =cache->spriteFrameByName(name);
plistArray->addObject(frame);
}
CCAnimation *plitAnimatinotallow=CCAnimation::createWithSpriteFrames(plistArray, 0.2f);
CCAnimate *plitAnimate=CCAnimate::create(plitAnimation);
CCActionInterval* plitSeq=(CCActionInterval*)(CCSequence::create(plitAnimate,
CCFlipX::create( true),
plitAnimate->copy()->autorelease(),
CCFlipX::create( false),
NULL
));
plistSprite->runAction(CCRepeatForever::create(plitSeq));
好啦，来看看最后的效果图

好运。
上一篇文章讲述了利用cocos2d-x构建精灵的动画效果，今天打算以此为引子，创建一个在移动时同时指挥角色到我手指触摸的移动地点，那么就开始吧。
开始
本篇要点
- 角色(Sprite)缓存
- 动画(Animation)缓存
- 触摸(Touch)精灵到我指定的移动地点
- 动作(Action)移动和切换
涉及到的要学的学习点：
- 角色移动点击由此进入-->cocos2d-x for android：SimpleGame分析
- 播放动画点击由此进入-->cocos2d-x for android：CCSprite 精灵动画
角色缓存
角色缓存使用CCSpriteFrameCache ，配合CCSpriteBatchNode将图片*.plist和*.png 加载进内存，方便以后调用。
以上为动作序列图，图片名称为：sg.png.图片来源于博客园:nowpaper.
角色缓存代码如下：
CCSpriteFrameCache* cache=CCSpriteFrameCache::sharedSpriteFrameCache();
cache->addSpriteFramesWithFile( " sg.plist ");
sprite=CCSprite::createWithSpriteFrameName( " A1_6.png ");
sprite->setPosition(ccp(size.width-sprite->getContentSize().width,size.height/ 2));
spriteBatchNode=CCSpriteBatchNode::create( " sg.png ");
spriteBatchNode->addChild(sprite);
addChild(spriteBatchNode);
CCSpriteFrameCache负责加载sg.plist，CCSpriteBatchNode负责加载sg.png，然后创建一个精灵指定初始化位置和精灵纹理，并添加进CCSpriteBatchNode。通过上面的代码即可以将一个plist序列图加载进缓存了，你要做的就是将这些缓存的数据拿出来操作它。
动画缓存
上面己经将数据加载进缓存了，可以使用其中的那些节点来制作动画缓存了。
缓存动画使用 CCAnimationCache，该动画同样需要使用到plist文件，代码如下
CCAnimationCache *animCache = CCAnimationCache::sharedAnimationCache();
animCache->addAnimationsWithFile( " sg.plist ");
在将plist文件添加完后，即可以通过动画Animation将每一个动画的Animation添加进CCAnimationCache了，这里我写了一个函数，代码见下方
CCAction* HelloWorld::createAction( int begin, int end, char* cacheActionName,CCPoint point){
CCAnimationCache *animCache = CCAnimationCache::sharedAnimationCache();//得到一个缓存对象
CCArray *array = CCArray::createWithCapacity(end-begin);
char name[ 20];
for( int i = begin ;i<end;i++){
sprintf(name, " A1_%d.png ",i);
CCSpriteFrame* frame =cache->spriteFrameByName(name);
array->addObject(frame);
}//以上创建一个动作序列集合
CCAnimation *plistAnimation = CCAnimation::createWithSpriteFrames(array, 0.2f);//通过动作序列集合创建animation
animCache->addAnimation(plistAnimation, cacheActionName);//添加进缓存并指定缓存名称
array->removeAllObjects();
CCAnimation *animation = animCache->animationByName(cacheActionName);//通过缓存名称得到一个动画
animation->setRestoreOriginalFrame( true);
CCAnimate *ani=CCAnimate::create(animation);
CCActionInterval* plistSeq=(CCActionInterval*)(CCSequence::create(ani,
CCFlipX::create(point.x> 0? true: false),
ani->copy()->autorelease(),
NULL
));
return CCRepeatForever::create(plistSeq);//创建动画并返回Action
}
触摸精灵到我指定的移动地点
设定好让程序允许Touch之后，在回调函数ccTouchesEnded 里面通过捕获触摸位置指定精灵移动，代码见下方
CCTouch* touch=(CCTouch*)(touches->anyObject());
CCPoint location = touch ->getLocation();
float offX=location.x-sprite->getPosition().x;
float offY=location.y-sprite->getPosition().y;
walkAction=createAction( 4, 6, " move
",ccp(offX,offY));
sprite->setFlipX(offX> 0? true: false);
float realX=offY/offX;
CCPoint realDeast =ccp(location.x,location.y);
CCActionInterval *actionTo=CCMoveTo::create( 2.2f,realDeast);
CCAction *moveToAction=CCSequence::create(
actionTo,
CCCallFunc::create( this,callfunc_selector(HelloWorld::moveDone)),
NULL
);
sprite->runAction(moveToAction);
ok了，精灵移动了，但你会发现，你想让精灵移动的时候不是一整张图片移动，而是边移动边两只脚在走路的移动，就像是我们人类一样，是走着过去的，而不是幽灵飘过去的，那么，我们要做些什么呢？
动作移动
其实，很简单 ，只要记住要精灵移动的时候即：MoveTo时，同时再让精灵执行一个动作即walk的动作，代码如下：
sprite->stopAllActions(); //因为Touch是无时无刻的，所以每当touch一次即停止当前的action
walkActinotallow=createAction( 4, 6, " move
",ccp(offX,offY));//构建一个walk的action
sprite->runAction(walkAction);//播放走的action
sprite->runAction(moveToAction);//播放moveTo的action
当到达指定地点时，希望让角色以站立的姿势站在屏幕上，这时我们需要在moveTo的callback函数里面调用，让其停止当前action，并重新执行站立的action,代码如下：
void HelloWorld::moveDone(){
sprite->stopAllActions();
CCAnimationCache *animCache = CCAnimationCache::sharedAnimationCache();
CCAnimation *standAnimation = animCache->animationByName( " stand ");
standAnimation->setRestoreOriginalFrame( true);
CCAnimate *standAni=CCAnimate::create(standAnimation);
CCActionInterval* s=(CCActionInterval*)(CCSequence::create(standAni,
standAni->copy()->autorelease(),
NULL
));
CCAction *frameActinotallow=CCRepeatForever::create(s);
sprite->runAction(frameAction);
}
全部代码如下：
using namespace cocos2d;
using namespace CocosDenshion;
#define LOG_TAG "main" ||- function
#define LOGD(...) __android_log_print(ANDROID_LOG_DEBUG,LOG_TAG,__VA_ARGS__)
CCScene* HelloWorld::scene()
{
// 'scene' is an autorelease object
CCScene *scene = CCScene::create();
// 'layer' is an autorelease object
HelloWorld *layer = HelloWorld::create();
// add layer as a child to scene
scene->addChild(layer);
// return the scene
return scene;
}
// on "init" you need to initialize your instance
bool HelloWorld::init()
{
//
// 1. super init first
if ( !CCLayer::init() )
{
return false;
}
this->setTouchEnabled(true);
CCSize size = CCDirector::sharedDirector()->getWinSize();
CCAnimationCache::purgeSharedAnimationCache();
CCAnimationCache *animCache = CCAnimationCache::sharedAnimationCache();
animCache->addAnimationsWithFile("sg.plist");
cache=CCSpriteFrameCache::sharedSpriteFrameCache();
cache->addSpriteFramesWithFile("sg.plist");
sprite=CCSprite::createWithSpriteFrameName("A1_6.png");
sprite->setPosition(ccp(size.width-sprite->getContentSize().width,size.height/2));
spriteBatchNode=CCSpriteBatchNode::create("sg.png");
spriteBatchNode->addChild(sprite);
addChild(spriteBatchNode);
cache->addSpriteFramesWithFile("hero.plist");
hero=CCSprite::createWithSpriteFrameName("Hero02_0.png");
hero->setPosition(ccp(hero->getContentSize().width,size.height/2));
heroBatchNode=CCSpriteBatchNode::create("hero.png");
heroBatchNode ->addChild(hero);
hero->setFlipX(true);
addChild(heroBatchNode);
attackArray =CCArray::createWithCapacity(4);
char attackName[20];
for(int i=0;i<4;i++){
sprintf(attackName,
"A1_%d.png",i);
CCSpriteFrame* frame =cache->spriteFrameByName(attackName);
attackArray->addObject(frame);
}
CCAnimation *attackAnimation =CCAnimation::createWithSpriteFrames(attackArray,0.2f);
CCAnimationCache::sharedAnimationCache()->addAnimation(attackAnimation, "attack");
attackArray->removeAllObjects();
standArray= CCArray::createWithCapacity(1);
char standName[20];
for(int i=6;i<7;i++){
sprintf(standName,
"A1_%d.png",i);
CCSpriteFrame* frame =cache->spriteFrameByName(standName);
standArray->addObject(frame);
}
CCAnimation *standAnimation =CCAnimation::createWithSpriteFrames(standArray,0.2f);
CCAnimationCache::sharedAnimationCache()->addAnimation(standAnimation, "stand");
standArray->removeAllObjects();
return true;
}
void HelloWorld::moveDone(){
//
sprite->stopAllActions();
CCAnimationCache *animCache = CCAnimationCache::sharedAnimationCache();
CCAnimation *standAnimation = animCache->animationByName("stand");
standAnimation->setRestoreOriginalFrame(true);
CCAnimate *standAni=CCAnimate::create(standAnimation);
CCActionInterval* s=(CCActionInterval*)(CCSequence::create(standAni,
standAni->copy()->autorelease(),
NULL
));
CCAction *frameActinotallow=CCRepeatForever::create(s);
sprite->runAction(frameAction);
}
CCAction* HelloWorld::createAction(int begin,int end,char* cacheActionName,CCPoint point){
CCAnimationCache *animCache = CCAnimationCache::sharedAnimationCache();
CCArray *array = CCArray::createWithCapacity(end-begin);
char name[20];
for(int i = begin ;i<end;i++){

}

CCAnimationCache::sharedAnimationCache()->addAnimation(plistAnimation, cacheActionName);
array->removeAllObjects();
CCAnimation *animation = animCache->animationByName(cacheActionName);
animation->setRestoreOriginalFrame(true);
CCAnimate *ani=CCAnimate::create(animation);
CCActionInterval* plistSeq=(CCActionInterval*)(CCSequence::create(ani,
CCFlipX::create(point.x>0? true:false),
ani->copy()->autorelease(),
NULL
));
return CCRepeatForever::create(plistSeq);
}
void HelloWorld::registerWithTouchDispatcher(){
CCDirector::sharedDirector()->getTouchDispatcher()->addStandardDelegate(this,0);
}
void HelloWorld::ccTouchesEnded(cocos2d::CCSet * touches,cocos2d::CCEvent * event){
sprite->stopAllActions();
CCTouch* touch=(CCTouch*)(touches->anyObject());
CCPoint location = touch ->getLocation();
float offX=location.x-sprite->getPosition().x;
float offY=location.y-sprite->getPosition().y;
walkActinotallow=createAction(4,6,"move",ccp(offX,offY));
sprite->setFlipX(offX>0?true:false);
float realX=offY/offX;
CCPoint realDeast =ccp(location.x,location.y);
CCActionInterval *actinotallow=CCMoveTo::create(2.2f,realDeast);
CCAction *moveToActinotallow=CCSequence::create(
actionTo,
CCCallFunc::create(this,callfunc_selector(HelloWorld::moveDone)),
NULL
);
sprite->runAction(walkAction);
sprite->runAction(moveToAction);
}
void HelloWorld::menuCloseCallback(CCObject* pSender)
{
CCDirector::sharedDirector()->end();
#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
exit(0);
#endif
注意点
CCAnimation *attackAnimation =CCAnimation::createWithSpriteFrames(attackArray,0.2f); 与
CCAnimation *attackAnimation =CCAnimation::createWithSpriteFrames(attackArray);因为站立action才一帧，所以我不打算指定时间，但是如果不指定时间，它无法成功切换action，这个目前还不清楚是为什么。
最后实现的效果如下：
由于是在ubuntu下开发，好像没有什么抓取屏幕gif 图片的软件可用，简单截一屏！！！
代码没有做任何的处理，很多多余的代码，做个DEMO可以看看就行！！！
代码下载：https://github.com/terryyhl/SpriteAnimation.git
粗略写了个Player类，用来测试人物的待机动作和奔跑动作的播放，以及两种动作的切换播放。
1，这里要用到plist文件，对于plist,我目前的理解就是：plist和xml很像，可以说就是xml, 不过在mac下面就成了plist，美术资源如果是一张有9个帧动作的图片，那么plist文件里就应该有9个dict节点来分别对应这9个动作，每个节点里的属性包括精灵大小、需要渲染的纹理矩形的左上角和右下角这两个点的坐标、坐标偏移值、精灵单张原始图片的大小...
最开始时是想通过setPostition和 setAnothorPoint来解决人物的原点位置设置，但发现可以直接在plist里设置offset偏移量来决定原点位置。
plist文件里的spriteOffset属性正好可以用来设置原点的位置。
这里给出我自己算出的spriteOffset坐标公式：
X = 人物单帧图片宽度的一半 减去 注册点到图片的右边距 （得到值可能是负数，就要负数，不要绝对值）
Y = 人物单帧图片高度的一半 减去 注册点到图片的底边
2，cocos2d-x真心很赞，图片纹理渲染优化都有处理，使用这种纹理缓存机制，可以避免重复渲染相同的纹理。
CCSpriteBatchNode, CCSpriteFrameCache, CCSpriteFrame, CCAnimation
3, 代码中包括触屏之后除了人物的动作切换，还有位移、水平转向的处理,代码借鉴了官方test里的例子，贴心的2dx团队呀有么有!!!
4,新手要注意，draw方法不是主动去调用的，这里是重写了父类的draw方法，在这里绘制了一下人物的脚下画了个十字以以表示原点位置，方便测试，
ccDrawLine()方法就是直接调用openGL ES的接口在屏幕上绘制一条线。那么draw方法是被谁调用的呢，是cocos2d-x的UI主线程。
