Hi,
I'm having a bit of trouble with getting jump moves and especially multiple jump moves working. Any help would be great! excuse the code, it may be a little all over the place and I could have totally the wrong method! I've also cut out a stringtokenizer class which I know works fine.
Thanks in advance,
Ronan
