Detailed Description

The arc descriptor describes an arc shape.

Constructor & Destructor Documentation

CArcDesc() [1/2]

CArcDesc::CArcDesc

(

)

The default contructor creates an arc descriptor whose angles are zero.

CArcDesc() [2/2]

CArcDesc::CArcDesc	(	const Vector2 &	p0,
		float	r,
		float	a0,
		float	a1,
		float	e = 1.0f )

This constructor creates an arc descriptor given the arc's center, radius, angles, and elasticity.

Parameters

p0	Position of center.
r	Radius.
a0	First angle.
a1	Second angle.
e	Elasticity.

Member Function Documentation

GetAngle0()

const float CArcDesc::GetAngle0

(

)

const

Reader function for angle 0.

Returns

Angle 0.

GetAngle1()

const float CArcDesc::GetAngle1

(

)

const

Reader function for angle 1.

Returns

Angle 1.

GetEndPts()

void CArcDesc::GetEndPts	(	Vector2 &	p0,
		Vector2 &	p1 ) const

Calculate the end points from the arc center, angles, and radius. Assumes that these values have already been set.

Parameters

p0	[out] An end point.
p1	[out] Another end point.

SetAngles()

void CArcDesc::SetAngles	(	float	a0,
		float	a1 )

Set the arc descriptor's angles, making sure to normalize them first.

Parameters

a0	The first angle.
a1	The second angle.
