Ah ok. I noticed that, just was curious about the "list" thing. Thanks again

I also have a button sub-class, so I am not sure if I should take that into consideration when working with the button. Here is the main ToggleButton class:

Please see my Value Display Tutorial scenario.

Sorry, i just wanted to ask something else. Do you know i am able to make my bullets disappear when it hits the rockets and also make an quick explosion??<Code Omitted>This is the code in my plane

The 'getNeighbours' method is more for gridded world (worlds that have a cell size greater than one where actors usually fit inside one cell). The 'getObjectsAtOffset' method might work a little better (in fact, you can use it four times to check on all four sides of the actor). If I read the instructions you gave correctly (presuming that the wording is correct), then you need to use at least two "List" methods (like 'get(int)', 'isEmpty()' and 'size()', to name a few methods that could be used).

You can scale the image to size before the world is created; however, you would need to use static content and it will happen during compilation of the project (before any World object is created): <Code Omitted>

Thanks

I said I don't know much about greenfoot, and I just said danpost because he has helped me a lot, just trying to share what I know, sorry for what I got wrong.

If there is only one healthBar object in each of your worlds, then you can change lines 21 and 22 of the Meteorite class to this: <Code Omitted>You can do similarly to lines 15 and 16 of the Ball class if you only have one Counter object in each of your worlds.

Thanks for that, i appreciate your help.

Use the 'getObjectsInRange' method: <Code Omitted>The above line will have its block of code execute if any are in range.

Not if you keep everything about the currency in your world class and use a simple actor object to display the currency. Please refer to by Value Display Tutorial scenario.

That works, thanks a ton!

Need to see all the codes from where 'addScore' is being called from.
