All i have is public void checkKeyPress() { if(Greenfoot.isKeyDown("up")) { setLocation(getX(), getY()-3); } if(Greenfoot.isKeyDown("down")) { setLocation(getX(), getY()+3); } if(Greenfoot.isKeyDown("right")) { setLocation(getX()+3, getY()); } if(Greenfoot.isKeyDown("left")) { setLocation(getX()-3, getY()); } } for he frog to move around with arrow keys I need help whenever the frog moves on top of the fly, the fly dissapears, and the score goes up

also when posting code it makes it easier if you use the code tags. like this:
public void act()
{
    random();
}
to use them look on the bottom of the text box there's a few blue words, one of them is code, press on that and a white text box appears, type or copy your code into there and press the green check when you're done and it appears in code form in your post and it makes it much easier to read

You could implement this:
if(isTouching(Fly.class))
{
    getWorld().removeObject(getOneIntersectingObject(Fly.class));
    score++;
}
my fly class is called Fly and the frog class Frog the variable where the Points are saved is called score Hope it helps

did you put any code for the fly after it was removed? because the remove must be the last thing you use the fly for

The removal was probably from something executed just prior to this code.
