Comments on: Processingjs & Box2d Physics! http://codeblog.shawson.co.uk/processingjs-box2d-physics/ development notes for my failing memory Wed, 16 May 2012 12:57:09 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Andor Salga http://codeblog.shawson.co.uk/processingjs-box2d-physics/comment-page-1/#comment-228 Andor Salga Wed, 19 May 2010 23:50:31 +0000 http://www.shawson.co.uk/codeblog/?p=540#comment-228 Awesome. Glad to hear you can use the IDEs. Don't forget to save every once in a while locally. I lost my work a few times while working in a coffee shop when the connection died. It took me a while to get started with Box2DJS. The documentation is there but the explanations aren't. The members are listed, but what do they do? I had to rely on examples to figure out how to get things working. And for the Twitter mashup, I was unable to delete bodies so the page has to reload so it doesn't slow to a crawl. Supposedly you can delete bodies, but it just doesn't work. I pulled out most of my hair trying to create rigid bodies which weren't rectangles or circles. There is a limitation for those and trying to work around it was a nightmare. If I ever get some more time, I'd like to get it working so I can finish the crayon physics thing. Here is another IDE I forgot to mention: http://obsessing.org/ There are a bunch of us on irc.mozilla.org at #processing.js if you want to chat. Good luck on the game! Awesome.

Cool examples too- I find the physics enabled projects the most engaging and interesting to work on. IDE's are great- Bespin in particular is very slick- brilliant find! This was a real limiting factor for me as i was having to code in the main processing ide, then copy and paste to javascript which just didnt seem like a good process! I'm just about to embark on an 8 week project making a "manic miner" type game as part of a competition with a few mates- we can use any tech we want- they are making this their very first xna project while i'm either going to use javascript native or with processingjs library! These new IDE's may have tipped the balance! How have you found working with Box2DJS? I've so far only used pBox2D which has been a bit of a pain as a lot of the data types and method signatures differ from Box2d and there's not much documentation on it!

You mentioned that PJS doesn't have an IDE. But there are a bunch! here is mine: matrix.senecac.on.ca/~asalga/pjswebide/ Bespin version: http://sketch.processing.org/ IDE on main site: http://processingjs.org/learning/ide I've also been playing around with these two libraries. If you're interested here's some stuff I made: Crayon physics prototype: http://matrix.senecac.on.ca/~asalga/DPS909/release0.2/work/demos/ Processing.js + Box2DJS + Twitter http://matrix.senecac.on.ca/~asalga/pjs_twitter If you figure out how to remove bodies from a scene, please let me know. Every time I try I run into JS errors. Nice to see you’re messing with these two libraries. You mentioned that PJS doesn’t have an IDE. But there are a bunch!
