I've find a great set of tutorials for ABS in RM2K on gamingw.net if those are any help?
RM2Kk had script ediotr right? Maybe they'll work in RMXP? It's a long shot...but...
I read those, they aren't the same thing (assuming that by ABS he wants a time-bar style system and not a Zelda-ish battle system). Also, they're just standard Auto Events that grab keystrokes and the like, not really scripting like with RGSS.
