Member Function Documentation

BBox()

const BOX2I SHAPE_NULL::BBox ( int  aClearance = 0 ) const

inlineoverridevirtual

Compute a bounding box of the shape, with a margin of aClearance a collision.

Parameters

aClearance

how much the bounding box is expanded wrs to the minimum enclosing rectangle for the shape.

Returns

the bounding box.

Implements SHAPE.

Clone()

SHAPE * SHAPE_NULL::Clone ( ) const

inlineoverridevirtual

Return a dynamically allocated copy of the shape.

Return values

copy	of the shape

Reimplemented from SHAPE.

Collide()

bool SHAPE_NULL::Collide ( const SEG &  aSeg, int  aClearance = 0, int *  aActual = nullptr, VECTOR2I *  aLocation = nullptr  ) const

inlineoverridevirtual

Check if the boundary of shape (this) lies closer to the segment aSeg than aClearance, indicating a collision.

Parameters

aActual	[out] an optional pointer to an int to be updated with the actual distance int the event of a collision.
aLocation	[out] an option pointer to a point to store a nearby location in the event of a collision.

Returns

true, if there is a collision.

Implements SHAPE.

IsSolid()

bool SHAPE_NULL::IsSolid ( ) const

inlineoverridevirtual

Implements SHAPE.

Move()

void SHAPE_NULL::Move ( const VECTOR2I &  aVector )

inlineoverridevirtual

Implements SHAPE.

Rotate()

void SHAPE_NULL::Rotate ( double  aAngle, const VECTOR2I &  aCenter = { 0, 0 }  )

inlineoverridevirtual

Parameters

aCenter	is the rotation center.
aAngle	rotation angle in radians.

Implements SHAPE.
