From source file:com.nuliy.example.Car.java

public void KillOrthoVelocity(Body body) {
    Vector2 localP = new Vector2(0, 0);
    Vector2 velocity = body.getLinearVelocityFromLocalPoint(localP);

    float r = body.getTransform().getRotation();
    Vector2 sideways = new Vector2((float) -Math.sin(r), (float) Math.cos(r));
    sideways.scl(velocity.dot(sideways));

    body.setLinearVelocity(sideways);/*  w  w w.java 2 s  . co m*/
