I see... ugly movement started when I emplemented fractional speed, maybe
because objects do a 2 lines movement, not single line since I'm not
using VDEL. I wonder if VDEL will solve this problem. I don't understand
well how it works but I'll read about it.
Hm... I wish I'd still have my old 266MHz machine, where enabling the log
would slow any game down so I could analyse all such behaviour.
I even tried generating an animated GIF out of Z26 screenshots, yet I'm
not 100% certain if Z26 will skip frames from screenshots or not...
You say "objects do a 2 lines movement", is that *just* the sprites?
Because I see rather the backgound as the problem. Or is everything moving
two lines at times?
Basically, if your maximum speed is <= 1 scanline per frame, it should
look much smoother I think.
Hm... if all your things are always moving 2 scanlines at once, maybe you
can shift the start of your screen by 1 scanline every other frame?
So over 4 frames it'd be like this:
1. Display extra scanline | move one step vertically
2. No extra scannline | don't move vertically
3. Display extra scanline | move one step vertically
4. No extra scannline | don't move vertically
You see, all objects would move one pixel per frame...
