is there anyone who can teach me? i don't know anything yet. please help me. a video tutorial will be helpful. Please. Thanks!

http://www.3dgamestudio.com/download.php

try out the tutorial section (like the lite-c workshop, it should be a good starting point for scripting)
there's also other links on that page

like this one which says it has a few free videos:
http://www.create3dgames.com/gsbasics.html
haven't seen it myself though

maybe even 'first step' on this one?
http://lion-ts.com/modules.php?name=Tutorials
looks like it covers the basics of making a simple game

well that should get you started

welcome to gamestudio, have fun, and don't get too annoyed at any bugs you will accidentally make : )
