I worked a lot of Flash, I have made a fighter, but they are very hard, I could never get the diffrent moves to do downpacked, so I went with just kick and punch.

Umm newgrounds is the best site for Flash Tutorials, they even give off links to other tutorial sites, when I find this one site which helped me even more then Newgrounds Ill post it

Heres a link to tons of Tutorials Hope this helps
