Side-Scroller Script

I need a side scroller script like that metroid game from phanxgames.

I don't want that ugly side-scroller script (where the player can't almost jump at all)
And i already have game maker 8 pro, but im making a side scroller rpg game.

The script should have more frames on the player (smooth walking)
And a jump sprite and jump sound, Also a ducking sprite and if not too much i also want the player to
be able to crawl.

I know alot of people have asked about one, but im asking if someone is willing to make one.
Becouse it's not impossible to have a side scroller game in rpg maker.

Look into Game Maker, or Stencyl (when it is released).

In order to make a side scroller in RMXP you'd have to code it from the ground up anyway (basically) so it'd be easier to use an engine more designed towards modification from the ground up.
