All the children will be drawn in a single batch. * * - Limitations * - Camera is not supported yet (eg: CCOrbitCamera action doesn't work) * - GridBase actions are not supported (eg: CCLens, CCRipple, CCTwirl) * - The Alias/Antialias property belongs to CCSpriteBatchNode, so you can't individually set the aliased property. * - The Blending function property belongs to CCSpriteBatchNode, so you can't individually set the blending function property. * - Parallax scroller is not supported, but can be simulated with a "proxy" sprite. * * If the parent is an standard CCNode, then CCSprite behaves like any other CCNode: * - It supports blending functions * - It supports aliasing / antialiasing * - But the rendering will be slower: 1 draw per children. * * The default anchorPoint in CCSprite is (0.5, 0.5). */ class CC_DLL CCSprite : public CCNode, public CCTextureProtocol, public CCRGBAProtocol { /** Opacity: conforms to CCRGBAProtocol protocol */ CC_PROPERTY(GLubyte, m_nOpacity, Opacity) /** Color: conforms with CCRGBAProtocol protocol */ CC_PROPERTY_PASS_BY_REF(ccColor3B, m_sColor, Color); public: virtual void draw(void); public: // attributes /** whether or not the Sprite needs to be updated in the Atlas */ inline virtual bool isDirty(void) { return m_bDirty; } /** make the Sprite to be updated in the Atlas. */ inline virtual void setDirty(bool bDirty) { m_bDirty = bDirty; } /** get the quad (tex coords, vertex coords and color) information */ inline ccV3F_C4B_T2F_Quad getQuad(void) { return m_sQuad; } /** returns whether or not the texture rectangle is rotated */ inline bool isTextureRectRotated(void) { return m_bRectRotated; } /** Set the index used on the TextureAtlas. */ inline unsigned int getAtlasIndex(void) { return m_uAtlasIndex; } /** Set the index used on the TextureAtlas. @warning Don't modify this value unless you know what you are doing */ inline void setAtlasIndex(unsigned int uAtlasIndex) { m_uAtlasIndex = uAtlasIndex; } /** returns the rect of the CCSprite in points */ inline const CCRect& getTextureRect(void) { return m_obRect; } inline CCTextureAtlas* getTextureAtlas(void) { return m_pobTextureAtlas; } inline void setTextureAtlas(CCTextureAtlas *pobTextureAtlas) { m_pobTextureAtlas = pobTextureAtlas; } CCSpriteBatchNode* getSpriteBatchNode(void); void setSpriteBatchNode(CCSpriteBatchNode *pobSpriteBatchNode); /** Get offset position of the sprite.
