How do I do a sidescrolling shooter game?

So, I'm a Stencyl newbie and am currently trying to figure out how to make a sidescrolling shooter game. I don't know if this question has been answered or not, but from what I've found, it isn't yet. (Provide a link if it has, please.) How exactly do you get a sidescrolling shooter to work?

there are actually things on stencyl forge to get you started

Dude, me too! I went through Crash Course 2, but center (default) disappeared, my ship is stuck in the top right corner, and only moves halfa space left or right. is that your problem too? O.o sorry it's late and I;ve been doing the tutorial ALL DAY LONG. wicked awesome.

To make the scene scroll sideways:
When you create the scene you get to choose how many tiles width/height is has, if you enter lets say 200 instead of the 20 (belive it says), then the scene is 10 times wider then the screen (if you chose 640x480 in game creation), then just attach a actor behaviour to make the camera follow your player and the game scrolls sideways as you move the actor.

That helps with the BG.

Now I need help on how to get the enemies to scroll onscreen like so.
