What all will be involved in your scenario? First, there are many ways to scroll. Universal, vertical, side, uni-directional (up only, down only, left only, or right only). Then, there is limited or infinite scrolling. Then, are you using a grid-world or pixel-sized cells? Do you want your image to repeat side-to-side and/or top-to-bottom? or just have an over-sized image for the window to scroll over?

Kartoffelbrot's code would work best if your actor moves faster than 1 pixel per move. My code would work best if your actor is moving only 1 pixel per move already. If you want more range at speeds slower than one pixel per move (other than 1/2, 1/3, 1/4, 1/5 speed, etc), you will have to use instance double fields to track your actors x and y locations, adjust them programmatically and move your actor accordingly using (int)x and (int)y.

1. Make a static int worms eaten variable called worms (if you don't already have one) 2. Add to that variable every time a worm is eaten 3. Add a class with this code <Code Omitted>

Yes; more lines of code might be added with the expectation that these will be conditionally executed, particularly if the user has a background in a language which uses indentation for scoping (such as Python). I've seen this happen before.

thanks guys :D

i dont think so :) /Edit: happens alot to me. like forgetting simple things

Thanks Holla and Danpost :D

got it now its working thank you very much for u help

Thanks, my problem was excactly that. Now it's solved :)

You can use the getObjectsInRange method (see the Greenfoot API) to check whether your actor is in a certain range of your enemy.

Thanks, I knew it would be something simple..

First, you would need to hold the GreenfootSound in an instance field in the class of your character (I will call it 'sound'). Then, in the class of the character, use 'getObjectsInRange' to see if a boomerang is in the desired range (I will use '80' for the range).
