Some of you may remember a long time ago I did write a tutorial on beat em up's, but it was in AS2, and had a few major flaws I picked up on, therefore it was removed.I figure now is the time to update those tutorials in AS3. This isn't going to be a straightforward making-from-scratch tutorial, rather a guide to the techniques involved. You'll have to do the grunt work yourself- no easy download FLA's for the lazybones here!-------------------------------------------------ADVANCED KEY-CAPTURE-------------------------------------------------Second...
