Hi guys, I just released the beta version of my first panda.js plugin. Download: https://github.com/stephan0v/Panda.js-physics-extention-plugin. Live demo: http://vermeire.home.xs4all.nl/panda/ Panda.js physics extention plugin. This plugin adds several features to the built in basic physics engine of Panda.js. Features: Collision between squares and circles is now far more realisic and follows the laws of physics.Gravity is no longer affected by the mass of the object.The effect of the gravity on individual bodies can be regulated now with the body.gravityFactor propertyYou can add squares that act like a wall with the body.fixed property.The bounciness of individual bodies can be regulated with the restitution propertyLimitations: Polygons/lines/triangles are not supportedBodies won't rotate on collision
