simpleParticle01 - 1.0

I wrote this in couple afternoons. Hadn’t done any projects like this in a while, but this was a simple task I wanted to tackle: Draw particles with the mouse, when close generate an interaction, and when the interaction occurs trigger an event. In a nutshell, that’s what this does:

  • LMB draws red, unfilled particles that slowly fall down the screen.
  • When they get close together, a latticework of lines will draw between them:
  • The more lines that connect them, the more opaque they get.
  • When the lines are created, a ‘burst’ of smaller white particles will emit from the larger red particle that spawned the line.

The app was mainly just written for leisure, it’s not that speedy. But was a nice relaxing thing to do over the weekend. If you grab just the source, you'll also need a fixed-up version of the Pygame vec2d lib, which you can download from my site here:

I didn't feel like in-lining the whole vec2d module in my module, but if you go to the home page link, I give you a direct download link to the fixedup version you can use.
AH, dependencies :) Glad you got it working.

This was neat to play with. I run Kubuntu, so with the single file source link, I found out that I needed to download the vec2d file from the wiki at and then that the file needed to have its Vec2d references changed to vec2d. So a little tinkering, not bad, but could be better for us who want to check out your code.

Anyway, thanks for sharing this, it was fun.
