The reason the explode object does not remove is because you are removing 'this' from the world first. Now there is no 'world' referenced. Switch the last two lines of code and the explode should remove. As far as fraction of objects, the only ways I can think of are (1) if you build the object in parts, or (2) if you change the image to reflect the remo val at given points.

We'd need to see your code for certain - but the above advice is a common cause! If you have declared a populate() method then check it's the same case (Java is case sensitive) and check your curly brackets are all in the right place which can also sometimes cause that error.

Also check out the Greenfoot videos (especially the ones on shooting).

Thanks to all, now it works fine ... and i understand it :D

Thanks so much davmac. You've really helped here!

awesome, thanks buddy. i was watching a tutorial on this topic (platform games) and had the same code, which in the tutorial, the code compiled with no errors. very strange! anyways, thanks!

By the way a replacement for: <Code Omitted>is:

needed rotation of the path so I modified last 2 lines, and it works.. Tnx!

I found that the problem is that we are calling GamePad.getNumGamePads() in the constructor of the world. Moving that call fixed our issues. I might go wake my son up to tell him the good news. He went to bed a bit sad earlier. :)

Yup, to run Greenfoot you'll need the JDK which you can download from here.

Actually, if you chain the method calls (as you do here) there is no need to import the List interface. You only need to import List if you refer to it directly, eg declare a variable of type List.

Thx.;) That works.:)

I know.;) Just wrote it like that.;)

Yeah, @danpost that's what I was talking about
