Method Detail

changeComplete

public void changeComplete(float complete)

Description copied from class: TimerView

Generate an unexpected change in the timer's completion and set up the necessary details to render interpolation from the old to new states

Overrides:

changeComplete in class TimerView

tick

public void tick(long tickStamp)

Description copied from interface: FrameParticipant

This is called on all registered frame participants, one for every frame. Following the tick the interface will be rendered, so participants can prepare themselves for their upcoming render in this method (making use of the timestamp provided for the frame if choreography is desired between different participants).

Specified by:

tick in interface FrameParticipant

Overrides:

tick in class TimerView

paint

public void paint(Graphics2D gfx,
                  float completed)

Description copied from class: TimerView

Paint the timer into the given graphics context at the inputted percent complete (0f means just started, 1f means just finished).

Overrides:

paint in class TimerView

setSandTrickleY

protected void setSandTrickleY()

Set the y position of the trickle.

getSandBottomTop

protected int getSandBottomTop(float completed)

Returns the current top coordinate of the bottom sand pile.
