Detailed Description

CObject is the abstract representation of an object. Notice that CObject has no move or draw functions. Moving and drawing is now handled by CShape.

Constructor & Destructor Documentation

CObject()

CObject::CObject	(	Shapes::CShape *	p,
		const CObjDesc &	d )

Constructor.

Parameters

p	Pointer to a shape.
d	Pointer to an object descriptor.

Member Function Documentation

DrawOutline()

void CObject::DrawOutline

(

)

Draw only the outline of the object's shape. This is reasonably cheap for line segments but hideously expensive for circles and arcs because it laboriously constructs the curve by drawing very short lines. Ideally I should put it into a pixel shader but I can't be bothered. This is good enough for now.

GetAABB()

const Shapes::CAabb2D & CObject::GetAABB

(

)

const

Reader function for the object's AABB. It gets this by querying the object's shape's AABB.

Returns

The object's AABB.

GetMotionType()

const Shapes::eMotion CObject::GetMotionType

(

)

const

Reader function for the object's motion type. It gets this by querying the object's shape's motion type.

Returns

The object's motion type.

GetShape()

Shapes::CShape * CObject::GetShape

(

)

const

Reader function for the object's shape.

Returns

A pointer to the object's shape.

Update()

void CObject::Update

(

)

Update object setting from its shape.
