BubblePaint v0.01

BubblePaint.001

This is the results of my latest efforts to learn PyGame using PyMunk, a Python wrapper around the Chipmunk 2D physics engine.  Eventually I hope to use this knowledge in a physics-based tank game, but right now, I’m just having fun ‘painting’ with the ‘bubbles’.  There’s no great magic going on in my opinion, just some weekend coding fun.

In a nutshell:

  • You paint with “bubbles” on the canvas using the mouse.  It expects you have a 3-button mouse with a scroll wheel in the middle (because that’s what I have).  Since its physics based, the bubbles will push each other around, and none will be overlapping (if given time to settle).
  • LMB-drag draws bubbles
  • MMB-drag up\down: changes bubble size. Bigger bubbles get darker, smaller bubbles get lighter.
  • RMB-drag up\down: change brush hue
  • Mouse-wheel: change pressure of bubbles (number applied at once, from 1->10)
  • ‘s’ will save ‘test.png’ in the install dir.

You can find the Python source here:

And you can find a zipped Windows executable here:

Future plans for this include:

  • Shapes other than circles (square, triangle, random-polygon)
  • Ability to enable gravity, and add static rigid bodies (more of a physics sandbox at that point)
  • Images for the ‘bubbles’ rather than just solid color.
  • The ability to ‘dry’ the canvas to allow for multiple layers of painting.
  • A smarter way to save images.
  • A toggleable overlay layer showing stats.
  • Change the background color.
  • User defined resolution.  Currently set to 768×768

But we’ll see how much of that happens, I have family coming into two for the next few weeks :)
