I wanted to have a Sponge for Game which inflates (changes Images) when hit. Also I wanted the player to be able to climb up only the inflated sponge. For the 2. thing i have no idea how to do it...

You can use the size (width or height, whichever you desire) to determine if the player can climb the sponge. Maybe something like this:

Actor sponge = getOneIntersectingObject(Sponge.class);
if (sponge != null
 && sponge.getImage().getWidth() >= 50
 && Greenfoot.isKeyDown("up"))
{
    climb();
}

Thx for the replie! i wanted to have an entirely different image for the sponge not a bigger version though. How could that be adjusted in the Code?

How many images do you have for the sponge from not inflated to inflated? What code do you have for inflating the sponge? Show Sponge class codes.

        small = new GreenfootImage("spongesmol.png");
        big = new GreenfootImage("spongeBEEG.png");
    }
    public void act()
    {
        if (isTouching(inklingshot.class)) 
        {
            setImage(big);
            removeTouching(inklingshot.class);
        }
    }
}

After line 10 (sponge class above), insert the following line:

setImage(small);

In the class of the player, use the following as conditions to climb::

sponge hitSponge = (Sponge)getOneIntersectingObject(sponge.class);
if (hitSponge != null && hitSponge.getImage() == hitSponge.big)
{
    // climbing code here
}
