Method Detail

• createState

  Momentum.State createState(Point initialPosition,
                           Point initialVelocity)

  Create a Momentum.State instance. The Momentum.State instance will be passed to updateState(State) until the momentum is depleted.

  Parameters:

  initialPosition - the initial position

  initialVelocity - the initial velocity in pixels per millisecond

• updateState

  boolean updateState(Momentum.State state)

  Update the state based on the specified Momentum.State. When no more momentum remains, this method should return false to stop future calls.

  The Momentum.State instance is created by a call to createState(Point, Point), and the same instance if used for the duration of the momentum. This method should modify the existing state by calling Momentum.State.setPosition(Point) and/or Momentum.State.setVelocity(Point).

  Parameters:

  state - the current state

  Returns:

  true to continue momentum, false if no momentum remains
