OrientedBody

protected OrientedBody(double m,
                       double r,
                       Vector2 o)

Constructs a body with the mass m, the radius r and the orientation o. The body resides in the origin and has a zero velocity and a zero acceleration. The body is corporeal and frictionless and has no owner.

Method Detail

getOrientation

public Vector2 getOrientation()

Returns the orientation of this body. The orientation is a unit vector (i.e., getOrientation().length() == 1.0).

setOrientation

public void setOrientation(Vector2 o)

Sets the orientation to o. The vector o needs not to be a unit vector. However, the resulting orientation vector is a unit vector that has the same direction as o.

getTangentFriction

public Friction getTangentFriction()

Returns the tangent friction.

setTangentFriction

public void setTangentFriction(Friction f)

Sets the tangent friction to f

getNormalFriction

public Friction getNormalFriction()

Returns the normal friction.

setNormalFriction

public void setNormalFriction(Friction f)

Sets the normal friction to f

futureVelocity

public Vector2 futureVelocity(double dt)

Returns the velocity of the body after dt seconds. If the body is not frictionless, tangent and normal frictions slow down the velocity.

Overrides:

futureVelocity in class Body

See Also:

Body.advance(double), Body.futurePosition(double)

toString

public java.lang.String toString()

Returns a string that contains the values of the attributes.

Overrides:

toString in class Body
