Public Member Functions
	DrawableOverlay ()

virtual	~DrawableOverlay ()=0

void	setAlpha (float alpha)

void	setSize (float widthN, float heightN)

void	setSize (float size)

void	setPosition (float newTLX, float newTLY)

void	getBoundingBox (BoundCube &b) const

bool	isOverlay () const
	This is an overlay. More...

Public Member Functions inherited from DrawableObj
	DrawableObj ()
	Constructor. More...

virtual unsigned int	getType () const =0

virtual DrawableObj *	clone () const

virtual bool	needsDepthSorting () const
	Do we need to do element based depth sorting? More...

virtual bool	isExplodable () const
	Can we break this object down into constituent elements? More...

virtual void	explode (std::vector< DrawableObj *> &simpleObjects)
	Break object down into simple elements. More...

virtual bool	hasChanged () const

void	setActive (bool active)
	Set the active state of the object. More...

virtual void	draw () const =0
	Pure virtual function - draw the object. More...

void	setInteract (bool canAct)
	Set if user can interact with object, needed for opengl hit testing. More...

virtual	~DrawableObj ()
