Memoirs of an X register - Horizontal Scrolling works, WHEEE!

[RSS Bot]

Well guys, after a lot of debugging, I have the horizontal scrolling motion working properly.. I have sped it up so that it could be seen.

 

I have attached the code below, but basically my approach is this:

 

* use the main line code to set global states, go left? go right?

* use the VBI to update actions that need to happen per frame, update the zero page locations for current HSCROL and LMS positions.

* use the DLI to update the HSCROL registers appropriately.

 

it's coming along, bit by bit... now it's time to put in the first bits of player code

 

(and no, this is NOT a final on the motion... I will be tweaking the motions using a lot of hand tables to give the illusion of speeding up and slowing down...)

 

what do you guys think?
