Hi,

I found this very very helpful, very indepth also - covers a lot of stuff. $45 is definatly worth the money.

Digital Tutors - Walk Cycle

check section 22 of the tutorial contents.

22. Bonus Lesson: Adding forward translation to the character so it moves forward

I will have a look at mine in a while and post a reply on how this can be achieved if you dont want to purchase it.

Hope this helps.

Thanks Mithandra
