#
I have been trying for a couple hours to add a life when the heart is pressed on and removed, not when it reaches the end of the world. Thank you very much.

You could consider adding the life in the 'playHitSound' method, which is executed only when the actor is "hit". You could also consider changing the name of the method to just 'hit' or 'wasHit'. If you do change the name, make sure you change it in its superclasses and other classes the extend them.

It's adding a life whenever it reaches end of world also, I dont want that. How do I fix this? public void playHitSound(){ Greenfoot.playSound("pop.wav"); //plays heart sound when hit ((FrogWorld) getWorld()).win(); }

In the Life class, you are only calling 'FrogHitter' when the actor reaches the end of the world. Switch lines 8 and 9 and then see what happens.

Change the act method to this:

public void act()

    setLocation(getX(), getY()-5);

    }
    FrogHitter();
}

That makes it so the heart does not appear on the screen. When a new heart is added, it just gives you a life instead of making the user press on the heart.

Maybe I am getting confused on your methods. Please post the FrotHit class (I think that is what I need to see).

Okay, I was thinking the check for click was in the FrogHitter method -- apparently not; and I did not (and still do not) see anything detecting a mouse click in the Life class. Wait, I remember, it was in a FrogHunter class. Just remove the 'FrogHitter();' line from the Life class.
