Using Spritesheets with Cocos2d-X

	// Using Spritesheets with Cocos2d-X

	//------------------------------------------------------------------
	// 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));
