Sprite Interference in Kick Off 2

msayed1977 · 20 February 2014, 05:28

Hi Toni,
The following phenomena is mostly normal, but I am not sure if.
In "Kick Off 2", when players cover each other (or part of), they are misshaped.

I haven't got a real Amiga to test, so please tell me whether it is normal or not. Of course if it is not, please try to fix.

You can look to the attached screenshot for more help.

EDIT: If it matters, this happens with all kinds of collision levels.

You will have to wait for a guy who still have the real thing to be sure.

This is normal behaviour and happens on a real Amiga too, Goal! has the same problem too.

I'm pretty sure this is the same as the original Kick Off. In an interview, Dino Dini said he XOR'd the graphics onto the pitch, hence 2 players in the same spot will effectively erase each other, and if they're partially overwriting each other, you'll get a weird mess of graphics! So this is not a WinUAE bug at all.

Click the "1988 - Technical Features - Atari ST version" link of Kick Off postmortem to go straight to the correct section.
