Backslide to Arcanum - Cosmic Orbs - Tech details
Hi there,
I recently wrote up some technical details about the demo I coded for Revision 2024. I don't think many people will see it otherwise, so I'm sharing it here where some of you might find it interesting: https://www.cosmicorbs.com/blog/backslide The demo and video links can be found here: https://www.pouet.net/prod.php?which=96604 Happy to answer any questions here. |

Little OT but one of my curiosities since am not a coder: how complicated would be to have a Mario Kart mode 7 interactive landscape on OCS/ECS? (not necessarily 1x1, i would say 4x4 is optimal, one playfield or max 4 bitplanes) and then in the other playfield all prescaled bobs for plants, obstacles, etc.

Thanks for the writeup! This was my favourite demo from Revision this year (against some strong competition) - it's always nice to see the thinking behind these kinds of productions.

For speed reasons, you could use a 128x256 (assuming you use 16 bits per pixel colour) source image for the "track" but that's going to look a bit naff. It does fit nicely in a word indexed address register offset. Ie "move X(a1),Y(a0) Then for something more useful for a game, you get into the realms of using a tile map, which slows things down immensely, due to needing to read your pixel from the tile before writing to the screen (chunky or copper screen) |

Generic question unrelated to the code side : could you please share the original protracker material for this prod, and any other forthcoming ? I _do_ hope there's more to come !

You'd have to ask Magnar. I don't think he would object. |

Excellent demo, saw it on Hoffmans stream last night, can't believe it only came 3rd.
Any other year and it was a 1st l Place finisher for sure. |
