Ultimate 2D Physics WIP
Press the following keys to spawn a polygon using:
E - elastic physics
R - rigid physics
S - static physics (none applied)
G - gravitational physics
Use the scroll wheel while hovering over a node to increase/decrease its mass/size
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.
