@Oswald,

@ChristopherJam, @Oswald, thanks for your comments.
@Oswald,
charsets are not only the key to achieve this effects. There is also simple raycasting routine to guess what neighbours (what shades) of pixels will be.
So we have 8 frames to:
- raycasting from matrix pixels to temporary screen,
- moving matrix pixels,
- drawing temporary screen to real screen,
- calc 2 charsets.
Yes. Because of unrolled code takes about 40kB, there is only one VIC bank left (bank 3). 6 charsets are static, 2kB is used to put dynamically calculated one of two missing/needed charsets. Last 2kB of free bank space is used for double buffering. |

| very very nice, but not as hard codewise, it needs careful consideration how the charset is built so all 8 frames of scrolling is possible just by plotting chars, animate through 8 charsets, you have 8 frames to draw a new screen. nevertheless looks ace. |

Yes, I was looking for any 2x1 font, but yours fits perfectly.
At first I thought about Japan Font 2x2 (v2) but they are 2x2, so too wide for fitting into sprites credits. |

Not only effect but also text in scroll was essential part of this release - related to science. Because scroll duration time was about 5:20, next time I will increase speed of scroll by 2 to fit in 2 minutes;))
@wacek @Jammer @Raistlin @katon @Yogibear @Flotsam @Joe Thanks for your comments! |

@Raistlin: not only coders ;)
@Gordian: as I watched this live at the party, I have a small suggestion. The patience of crowd in the multiplatform parties is radically different than on C64 only parties. The length and "watch till the end" requirement would work without any problems on X or Moonshine Dragons, as we are used to scrolls. Here the audience got really impatient after I think first 2 minutes, got bored and started loudly expressing that, as the orgas kept their commitment and played this till the end. Just something to think over next time, if you decide to remotely contribute to multiplatform parties in the future ;) |

Very nicely done! Some solid work here getting everything to pack into the charsets. One of those effects that only coders can appreciate. C64 isn't built for splitscreen horizontal scrolling ;-)
Great great work, can't wait to see what you do next. |
