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):
// field
private boolean altBackground;
// via act
MouseInfo 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");
