Help with rpg game

well I want to make a game in flash and I got codes for movement and hittest with buildings and stuff.
I have some problems with other scripts I need to figure out.
the game soppused to be scripted like zelda basiclly( character moves around, talk to people and attack with a sword)
but I want it to be with gta-style gameplay ( when you talk to people they give you missions).
I asked some forums on how to do that stuff but they keep ignoring or just post stupid replys…
so if you want to help me, here is what I need you to help me with:

  • attacking- shooting , sword or melee
  • scrolling (smooth scrolling or screen transitions)
  • inventory(with getting and giving items on inventory)
  • process of talking someone (how to use triggers?)
