Ultimate 2D Physics 2.1
Press space to spawn a new polygon.
Click on nodes to "freeze" them, click and drag to move them. Click and drag elsewhere to create a force.
Click on stage to add a new node. Click on existing nodes to select them: select 2 to create a link between them.
To delete a node, click on it. Any links to the node will be erased as well.
After coming back to this, I decided to create more than just elastics. I've added rigid physics (which get wonky with lots of links) and created lots of backup scripts to help organize the code. Planned features include spherical collision, linear intersection, and more...
[Physics intensifies] glitch. :P
