protected void updateDisplay() {
  StringBuffer buf = new StringBuffer();
  if (notifications.isEmpty()) {
   buf.append("No notifications. Pause and resume the game to generate some.");
  } else {
   buf.append("Notifications:\n");
   for (String note : notifications)
    buf.append(note).append("\n");
  }
  TextLayout layout = game.graphics.layoutText(buf.toString(), new TextFormat());
  Canvas canvas = game.graphics.createCanvas(layout.size);
  canvas.setFillColor(0xFF000000).fillText(layout, 0, 0);
  layer.setTile(canvas.toTexture());
 }
}
