If you’re new to Processing, start at the beginning!

This will be the simplest 2D collision physics possible, with nothing extra whatsoever, and the math is surprisingly simple!

I do not presume that I could build something of that power and complexity, but the idea is very [...]]]> http://cadjunkie.com/1547/parametric-drawing-in-processing/feed 0 http://cadjunkie.com/1537/matching-v011 http://cadjunkie.com/1537/matching-v011#comments Fri, 16 Apr 2010 04:34:11 +0000 adam http://adam.theoherns.com/?p=1537 This is getting fun! It’s official, folks. This has been such an incredible learning experience for me! I’m getting pretty comfortable with Processing at this point, and I’m even starting to leverage some external libraries. The game now supports a few different modes, and it’s getting pretty hard! Turn all of the types on (except [...]]]> http://cadjunkie.com/1537/matching-v011/feed 0 http://cadjunkie.com/1532/addition-matching http://cadjunkie.com/1532/addition-matching#comments Tue, 13 Apr 2010 04:14:43 +0000 adam http://adam.theoherns.com/?p=1532 Okay kids, here’s version v010 of the “matching” game I’ve been working on. Yes, this is what that whole “rectangular collision engine” was all about. It’s still really early days, but at least this is a proof of concept, and it’s FRIGGIN’ HARD. I can only imagine how much harder it would be if you [...]]]> http://cadjunkie.com/1532/addition-matching/feed 2 http://cadjunkie.com/1517/collision-engine-v006 http://cadjunkie.com/1517/collision-engine-v006#comments Sat, 03 Apr 2010 18:16:55 +0000 adam http://adam.theoherns.com/?p=1517 This is part of a series of posts chronicling the development of a math game involving collisions between rectangular objects on the screen, using a java framework called Processing. Physics are still a little wonky, but as a proof of concept, the collision engine is coming along beautifully.

The simplest of my ideas was a basic quiz game, where the user simply types answers to questions of simple arithmetic.

Take a look at WordPress.org, and you’ll notice their motto at the bottom-right of every page: ‘Code is Poetry’.
