Public Member Functions
	Sprite2D (Context *context)
	Construct.
virtual	~Sprite2D ()
	Destruct.
virtual bool	BeginLoad (Deserializer &source)
	Load resource from stream. May be called from a worker thread. Return true if successful.
virtual bool	EndLoad ()
	Finish resource loading. Always called from the main thread. Return true if successful.
void	SetTexture (Texture2D *texture)
	Set texture.
void	SetRectangle (const IntRect &rectangle)

	Set sprite sheet.
Texture2D *	GetTexture () const
	Return texture.
const IntRect &	GetRectangle () const
	Return rectangle.

	Return offset.
float	GetTextureEdgeOffset () const
	Return texture edge offset.
SpriteSheet2D *	GetSpriteSheet () const
	Return sprite sheet.
bool	GetDrawRectangle (Rect &rect, bool flipX=false, bool flipY=false) const
	Return draw rectangle.
bool	GetDrawRectangle (Rect &rect, const Vector2 &hotSpot, bool flipX=false, bool flipY=false) const
	Return draw rectangle with custom hot spot.
bool	GetTextureRectangle (Rect &rect, bool flipX=false, bool flipY=false) const
	Return texture rectangle.
Public Member Functions inherited from Urho3D::Resource
	Resource (Context *context)
	Construct.
bool	Load (Deserializer &source)
	Load resource synchronously. Call both BeginLoad() & EndLoad() and return true if both succeeded.
virtual bool	Save (Serializer &dest) const
	Save resource. Return true if successful.
void	SetName (const String &name)
	Set name.
void	SetMemoryUse (unsigned size)
	Set memory use in bytes, possibly approximate.
void	ResetUseTimer ()
	Reset last used timer.
void	SetAsyncLoadState (AsyncLoadState newState)
	Set the asynchronous loading state. Called by ResourceCache. Resources in the middle of asynchronous loading are not normally returned to user.
const String &	GetName () const
	Return name.
StringHash	GetNameHash () const
	Return name hash.
unsigned	GetMemoryUse () const
	Return memory use in bytes, possibly approximate.
unsigned	GetUseTimer ()
	Return time since last use in milliseconds. If referred to elsewhere than in the resource cache, returns always zero.
AsyncLoadState	GetAsyncLoadState () const
	Return the asynchronous loading state.
Public Member Functions inherited from Urho3D::Object
	Object (Context *context)
	Construct.
virtual	~Object ()
	Destruct. Clean up self from event sender & receiver structures.
virtual StringHash	GetType () const =0
	Return type hash.

	Check current instance is type of specified type.
bool	IsInstanceOf (const TypeInfo *typeInfo) const
	Check current instance is type of specified type.
template<typename T >
bool	IsInstanceOf () const
	Check current instance is type of specified class.

	Subscribe to an event that can be sent by any sender.
void	SubscribeToEvent (Object *sender, StringHash eventType, EventHandler *handler)
	Subscribe to a specific sender's event.
void	UnsubscribeFromEvent (StringHash eventType)
	Unsubscribe from an event.
void	UnsubscribeFromEvent (Object *sender, StringHash eventType)
	Unsubscribe from a specific sender's event.
void	UnsubscribeFromEvents (Object *sender)
	Unsubscribe from a specific sender's events.
void	UnsubscribeFromAllEvents ()
	Unsubscribe from all events.
void	UnsubscribeFromAllEventsExcept (const PODVector< StringHash > &exceptions, bool onlyUserData)

	Send event to all subscribers.
void	SendEvent (StringHash eventType, VariantMap &eventData)
	Send event with parameters to all subscribers. More...
VariantMap &	GetEventDataMap () const

template<class T >
T *	GetSubsystem () const
	Template version of returning a subsystem.
const String &	GetCategory () const
	Return object category. Categories are (optionally) registered along with the object factory. Return an empty string if the object category is not registered.
