Member Function Documentation

void CBody::ApplyTorque	(	float	angle,
		float	magnitude
	)

Apply a torque by delivering impulse to edge particle.

Deliver torque to body. This is achieved by delivering an impulse to a particle on the outside of the body.

Parameters

angle	Orientation of torque.
magnitude	Magnitude of torque.

void CBody::DeliverImpulse	(	float	angle,
		float	magnitude
	)

Deliver impulse to body.

Deliver impulse to body.

Parameters

angle	Orientation of impulse.
magnitude	Magnitude of impulse.

CParticle * CBody::MakeChain	(	int	count,
		int	radius,
		float	r,
		float	angle
	)

Make a chain body.

Make a chain of points in a straight line connected by springs.

Parameters

count	Number of points
radius	Half the length of one of the springs.
r	Coefficient of restitution of the springs.
angle	Angle that the chain makes with the horizontal.

CParticle * CBody::MakeRagdoll

(

)

Make a ragdoll body.

Make a cross-braced stick figure with spring constraints.

CParticle * CBody::MakeSquare	(	int	radius,
		float	r
	)

Make a square body.

Make a cross-braced square of points connected by springs.

Parameters

radius	Half the length of one of the springs.
r	Coefficient of restitution of the springs.

CParticle * CBody::MakeTriangle	(	int	radius,
		float	r
	)

Make a triangle body.

Make a triangle of points connected by springs.

Parameters

radius	Half the length of one of the springs.
r	Coefficient of restitution of the springs.

CParticle * CBody::MakeWheel	(	int	sides,
		int	radius,
		float	r
	)

Make a wheel body.

Make a cross-braced wheel of points connected by springs.

Parameters

sides	Number of sides to the wheel.
radius	Half the length of one of the springs.
r	Coefficient of restitution of the springs.

void CBody::move

(

)

Move body.

Move the body. Since the components of the body (particles and springs) are responsible for moving themselves, all we need to do here is to orient the particles at the ends and middle of the springs correctly.

void CBody::Teleport	(	float	xdelta,
		float	ydelta
	)

Magically teleport body by this amount.

Teleport the body without moving any of the particle relative to each other.

Parameters

xdelta	Amount to move horizontally.
ydelta	Amount to move vertically.
