Re: Are there any Physics Engines for use with XNA GS?

I just want to say that for 2D, Farseer is AMAZING! It took me less than 15 min to fully integrate it in my game/engine and it works like a charm. I also wonder, if I wanted to use one of the 3D ones, which shold I go for? I haven't had time to test anyone yet but JigLibX looks really good. What do you say? BTW: I couldn't write a less-than sign, is this forum interpreting html-tags? Is this a bug or feature? test

Okay thanks. Sorry, I must have missed that!

Might want to note somewhere that I couldn't get any of these in the top half of the list except Oops! to actually run. And one prompted VS to give a bunch of security warnings... :-(

I think my post got deleted. Anyway, the link to Newton is broken.

Are there any Physics Engines for use with XNA GS?

If you require code that will run on Xbox 360 or Zune then you need a 100% managed engine.

Most of these are free, or are free wrappers around commercial products. You should look at each one and determine pricing and licensing.

Farseer - 2d only. Source and Silverlight port available
JigLibX - Source available, port of C++ JigLib, formerly JiggleX
Bullet
- BulletX: By XnaDevRu: Supports Xbox360 as well as windows. Updated recently (dec 21 2007).
- XBAP: By Chris Cavanagh, buildt on BulletX above.
Newton
Oops! 3D Physics Framework
Bepu physics - commercial but free for non commercial use
Jello Physics - soft body physics. Used in JelloCar and other fun Walaber games.
Physics2D.Net - see demo video

If you are only targetting windows then you can use any of the commercial, or open source engines. Some have managed wrappers or you may need to roll your own

PhysX
- MS Robotics Studio has a wrapper but check the license.
- http://code.google.com/p/physxdotnet/
ODE (Open Dyamics Engine)
- XPA (XNA Physics lib): XnaDevRu has a nice wrapper for, but it's majorly outdated and ODE is rumored to be bad/unstable. There's very little information about it, but the API is pretty friendly. Pretty easy to get up and running with simple collisions (even I made it!), but its hard to find what you need when problems occur, and its updated very slowly.
Newton Game Dynamics
- [link appears to have died] Newton physics: Was written in 8-10 hours so I guess its quality reflects that.
