Title: Dot-matrix engine for AGA
Post by: saimo on April 14, 2019, 02:00:49 PM
In the past months I've been thinking of some new game concept that would finally put my dot-matrix engine for AGA Amigas to good use. Admittedly, I haven't come up with anything worthy yet, but I've been doing some technical experiments. I thought you might fancy having a look at the latest experiment:

Note that I'm NOT going to make a beat'em up. Again, this is just an experiment.

Looks really good. My mind boggles at the maths that must be behind that.

Nothing particularly special, to be honest.

This video shows a stock Amiga 1200 running various visual effects using the dot-matrix engine. The effects are obtained by means of a system that allows every single pixel to be located anywhere in memory (regardless of the RAM type). Lately, I've started thinking again of a game that makes use of the dot-matrix engine, and I came up with this new system. I finally have a somewhat interesting game concept (not shown here), but I'm still thinking of better alternatives.
Technical note: while the dot-matrix engine doesn't require any CPU operation, this new system is entirely CPU-driven, so each screen update takes more or less 1.3 frames on a stock A1200; therefore, if the game eventually uses the system, it will run at most at 25 fps.

Would be cool as a native video format too - movie.dmv, dot-matrix video :)

Well, conceptually, the only difference with any existing format is that the depth is just 2 bits. Anyway, boooring ;D
