add this somewhere
Code:
Graphics2D g2d = (Graphics2D) super.graphics;
bubbleCell = new BubbleCell(20);
and this somewhere thats called on loop ie drawloginscreen
Code:
super.graphics.setColor(Color.black);
super.graphics.fillRect(0, 0, 765, 503);
for (int i = 0; i < bubbleCell.cells.size(); i++) {
BubbleCell cell = bubbleCell.cells.get(i);
cell.process((Graphics2D) super.graphics);
}
result
