How hard is it to make a background "scroll" on th

[Cassidy Nolen]

Hi all,

 

Just wondering if what I am thinking of doing is possible. Could you make a background (like the one on Outlaw) scroll from top to bottom? The effect would be the cactus moving from the top to the bottom of the screen, maybe once every 5 or 6 seconds.

 

I am trying to get the details for a game I would like to try. I used graph paper and know that my Player 1 would be fine. Now just wondering if I can make the background "exciting".

 

Did I mention I would like to do it in a 2K game?

 

Thanks for the advice.

There's a variation in Outlaw that has a wagon, that I thought DID scroll from top to bottom....

I assume you are talking about the 2600...

 

Shouldn't be to hard to do this. Since you have to stuff the playfield data every frame anyway it should be pretty easy to change the scanline on which you start displaying the background objects to achieve the scrolling effect.
