 |  Re: Terra Cognita and flickering enemies
Love Terra Cognita too, I second you.
At the moment, I'm away of any kind of real computer or emulator and can't test it. But reading your post, one thing comes in my mind clearly: if the main routine mainly inlcude the softsprites' drawing subroutine, and the former starts to calculate basically from the last row of the visible screen, occurring in any case in a sprite flickering at some point, then could be possible that this already represents the less annoying choice to display the sprites while a vertical scrolling occurs too, simply due to the laboured code needed.
I confirm what I said in brief: mine is a theoretical consideration, not even a real thing, hence: testers, ahoy! 
EDIT: mmmh... Watching your videos, it doesn't look like a flickering driven by scanline's misplacement, it looks like a flaw in the sprites' calculation, which consequently burden over it. |
