Hi newgrounds! It's been 3 years since the last game i made. And had been involving study for years, recently i came back to Flash with AS3.0 and written some physics stuff and wanting to write some games on it. It's just fun! :)
For the simulation, i trade-off the cheap calculation to real-time achievable, instead of using step-simulation, i introduced penetration depth recovery, the drawback is however the in-accurate and artifact introduced when penetrating happens too deep.
Hope to integrate more physics stuff into the system and make a game to it. :)
