never not loving how the latest New Gods book's " let's loop in every character that's been peripherally tied to them " included alluding to that in one panel

Haven't posted about Rampant on the Tracks for a bit - been reworking the Track generation logic. You can see the result below, before and after - more detailed writeup to come. #procgen #proceduralgeneration #gamedev #solodev #indiedev

Rampant on the Tracks " Track " generated with Voronoi points

I love that Peter Cheyney created a character named " Lemmy Caution ", and that a sequential list of the Caution book titles reads like a conversation

Building a lightweight Android app for easily identifying the complementary colors between two extracted from a picture taken - got a demo at jpshh.com (" Color Spectrum Calculator ") that shows its core logic by letting you pick the two " extreme " colors.

this is rendered by drawing a line whose RGBA color is (0, 0, 0, 0) and applying a shader to it. the bar's progress is a Tween, on which the alpha of the Action Bar's color is also dependent.

Taking actions in Rampant on the Tracks is limited by this Action Bar - it's cut in half with every Block or Redirect applied, and blocks any action at 25% or below. It runs down and back up on its own - you'll have to act when you can. #godot #godotdev #gamedev #indiedev #solodev

this is done with a shader on the focus element that draws the Walker's color on all pixels within " walker_radius " of its current position

jpshh @jpshh.com · 17/06/2026

When focusing on a Track segment a Walker's crossing in Rampant on the Tracks, you can see the Walker there too in simplified form - you won't have to look back and forth between Track and focus. #godot #godotdev #gamedev #indiedev #solodev

Further refined my game's Track generation logic to minimize " nodes " overlapping with other nodes/edges. Demo that isn't just a Matplotlib gif coming soon! (Blue = Track " start ", red = Track " end ".) #procgen #proceduralgeneration #gamedev #solodev #indiedev

Parts of my game's level generation logic generated level " segments " too close to others, or too small for their traversal meaningful - implemented logic to correct those by combining " too small " edges with the nearest and largest. #procgen #proceduralgeneration #gamedev #solodev #indiedev

Level generation pre-correction - features multiple segments too close others to others and/or with too short lengths.

Level generation post-correction - segments are more evenly spaced out, and average minimum segment length is longer.

Switched my game's level generation logic from managing level state with the single-threaded networkX to the multi-threaded rustworkx - cut the average level generation time down to a third! #procgen #proceduralgeneration #gamedev #solodev #indiedev

If you need a Python module that outputs SciPy's Voronoi diagram generation in easier-to-parse JSON for #proceduralgeneration or #procgen purposes, I've got one: pypi.org/project/Voro... Example output in Matplotlib (number of sites 15, 45, 135, 405):

Voronoi diagram with 15 sites, generated by Voronout and graphed in Matplotlib.

Voronoi diagram with 45 sites, generated by Voronout and graphed in Matplotlib

Voronoi diagram with 135 sites, generated by Voronout and graphed in Matplotlib
