//------------------------------------------------------------------
// So how does one use a spritesheet with Cocos2d-X? 
// The first thing you've got to do is load the texture file 
// and cache the sprite frames: 
 
// set the appropriate resource directory for this device. HD/HDR/SD, etc...
CCFileUtils::sharedFileUtils()->setResourceDirectory( "HD" );

// load and cache the texture and sprite frames
auto cacher = CCSpriteFrameCache::sharedSpriteFrameCache();
cacher->addSpriteFramesWithFile( "Ninja.plist" );

//------------------------------------------------------------------
// Here's how to create a sprite using one of the sprite frames: 
CCSprite* someSprite = new CCSprite;
someSprite->initWithSpriteFrameName( "ninja-stopped0000.png" );

//------------------------------------------------------------------
// To individually get one of the sprite frames: 
// get the sprite frame
CCSpriteFrame* frame = cacher->spriteFrameByName( "ninja-sidekick-e0007.png" );

// set someSprite's display frame
someSprite->setDisplayFrame( frame );

//------------------------------------------------------------------
//To play an animation: 
// load all the animation frames into an array
const int kNumberOfFrames = 13;
CCArray* frames = new CCArray;
frames->initWithCapacity(kNumberOfFrames);
for( int i = 0; i < kNumberOfFrames; i++ )
{
   CCString* filename =
      CCString::createWithFormat("ninja-sidekick-e%04d.png", i);
   frames->addObject(cacher->spriteFrameByName(filename->getCString()));
}

// play the animation
CCAnimation* anim = new CCAnimation;
anim->initWithSpriteFrames(frames);
someSprite->runAction(CCAnimate::create(anim));
