I find it mesmerizing. Here's the prog8 port. It runs faster, but not very much, due to the heavy use of floating point math in both cases. bubbleuniverse.prg %import graphics %import floats %import math %option no_sysinit ; Bubble Universe ; see: https://stardot.org.uk/forums/viewtopic.php?f=54&am...

Need more characters on the screen for your onboard editor/assembler/compiler/debugger? This demo shows a 106 (columns) x 60 (rows) character display. Each character fits within a 6x8 pixel cell, with most characters fitting within a 5x7 section of the cell. Many block (line drawing) characters use ...

You mentioned Prog8 in my thread about Desired Development tools, so I checked it out (Programming in Prog8 web page, and in the forum here). Looks interesting, and good work, BTW. Seems that this discussion hasn't happened in recent days. What's the status of Prog8? Any new developments? Has anybod...

Hey, folks. Late-comer here. I'm wondering how far you got with this external communication board development. Is it nailed down? Is it working? What were the final transfer rates? Thanks.

Thanks! I'm using it in a game project. There are 25 directories with images involved. Each directory has images for sprites and tiles. The tool computes the palette for each directory, such that all of its images can appear on the screen using a single palette. So, there are 25 palette files, plus ...

I didn't realize that the 2 dummy address bytes needed to be at the front of the output binary image files, in order to load them with the VLOAD command in BASIC. I have modified the program to insert those 2 zero bytes at the head of the binary image data, so those ".BIN" files will also ...

Uploaded a small fix, yielding V1.1 of this tool. The code was converting the entire output file path to upper-case, rather than just the last portion (filename plus extension) of it. With the change, the first portion of the path is left as-is. FYI.

Are you still working on this? I had some thoughts that might help, if you like. First, either pre-compute the rotated X/Y coordinates, or at least use integer sin/cos tables (possibly with interpolation, but preferably not) to get your angles. Second, switch to sprites, and don't draw at all. Third...

This is the 2nd part of a demo showing 128 sprites. This application adds collision detection. The details are in the README file in the repository, but the collision detection involves combining several techniques, including pre-computing many numbers needed to make the demo happen. Specifically, t...

Using a C program to generate a table of pre-computed X and Y coordinates is exactly how I did this demo. In the 8-bit world, we have to limit runtime calculations.
