Method Details

onFrame

public boolean onFrame(ViewPanel viewPanel,
 int millisecondsSinceLastFrame)

Description copied from interface: FrameListener

Called before each frame render, allowing the listener to update state and indicate whether a repaint is needed.

Each registered listener is called exactly once per frame tick. The frame is only rendered if at least one listener returns true (or if the view was explicitly marked for repaint).

Specified by:

onFrame in interface FrameListener

Parameters:

viewPanel - the view panel being rendered

millisecondsSinceLastFrame - time elapsed since the previous frame, for frame-rate-independent updates

Returns:

true if the view should be re-rendered this frame, false if this listener has no visual changes

isKeyPressed

public boolean isKeyPressed(int keyCode)

Returns whether the specified key is currently pressed.

Parameters:

keyCode - the key code (from KeyEvent)

Returns:

true if the key is currently pressed
