Member Function Documentation

pair< WorldObject *, CollisionObject * > CollisionCircle::collision	(	const CollisionRectangle *	c,
		WorldObject *	wo,
		WorldObject *	mObj
	)		const

This does collision between Rectangles and Circles.

Parameters

c	a single collision data for an object
wo	Pointer to Object with checking bound
mObj	the current collision's world object

Returns

Returns true if any of the object's collision datas are colliding .

check rect vs circle

Here is the caller graph for this function:

pair< WorldObject *, CollisionObject * > CollisionCircle::collision ( const CollisionObject *  c, WorldObject *  wo, WorldObject *  mObj  ) const

virtual

Check collision with objects implements circle on circle.

Parameters

c	a single collision data for an object
wo	Pointer to Object with checking bound
mObj	the current collision's world object

Returns

Returns true if any of the object's collision datas are colliding .

call the circle rect fn

Here is the call graph for this function:

void CollisionCircle::draw ( const Point2D &  pos )

virtual

Draws the collision data to the screen.

<The relative x,y pos

<the midpt of the circle

This provides a simple interface to determine types of objects.

Returns the name of the Class and Descendants i.e. Something inheriting from Sprite would look like Sprite:Thing
