Hi guys, I want to create a code, that changes the background when I am with the mouth over a specific area of the background. Do you know how to do that?

Change Background while Mouse ist over a specific area
Use a boolean field to indicate mouse being over that area or not (or indicating background state):
1 2 3 4 5 6 7 8 9 10 | // fieldprivate boolean altBackground;// via actMouseInfo mouse = Greenfoot.getMouseInfo();if (mouse != null && (mouse.getX > 100 && mouse.getX() < 200 && mouse.getY() > 300 && mouse.getY() < 400) != altBackground){ altBackground = ! altBackground; setBackground(altBackground ? "altBackground.jpg" : "mainBackground.jpg");} |
