ACS Tutorials?

Hi, I have *ZERO* experience with ACS, and I would like to begin learning... are there any tutorials out there that I can look at or someone who is willing to show me some stuff? (Note that my ACS stuff is for Zdoom)

Or if someone could tell me how to do this...

Player crosses a line that triggers a script that has a marine shooting at the palyer after a gunshot the screen goes black and a short message appears... then the player is transported to the next map...

I would appriciate any help you can give me... I'm not too new to mapping but ACS is a whole nother story :P
Thanks all, be safe

Did you try the "Tutorials" link on the ZDoom page? ;)
