I've created a simple bridge design game with the Farseer Physics Engine. The goal is to build the best bridge you can, and then destroy it. The better the bridge, the harder it is to destroy it, or at least that is the hope!
I know it is still not that realistic at this point, but I'm still tweaking all of the physics parameters. If you have any suggestions on how to make it more realistic, please let me know!

Very cool.

I posted about it on my blog...

I'll play it some more when I'm not at work and let you know if I see anything I think could be improved.

I posted your game to the Fun-Motion forums. Some of them are having trouble getting the game to run. Just thought you might want to know.

Here is the thread:

thanks for the heads up! i thought all the bugs were worked out, i had already stamped it with the 'works on my machine certification'...

Nice game, but I can't play - every time when I start building bridge it restarting. This same when try to run simulation.

Are you saying that when you click the 'Build' button on the top right, the game restarts? It doesn't show any popups with error information? If you don't mind, please try it again and post your bridge code. Thanks!

Now I can see error message:

This may be the "Locals" bug. It causes exceptions on non English systems.

It's an easy fix...

crashlander, you are the man. that is precisely the problem. i fixed a few instances of it this morning, but i'll have to look at it more when i get home from work.

also, that is a really cool forum you posted Bridge Breaker at. i've never been there before.

Yeah, Fun-Motion is a great place to test out physics games before releasing them to the masses.

I've renamed the game to Bridge Basher. Apparently, Bridge Breaker is already a registered trademark name. I should've done my homework before naming it in the first place, I suppose.

I've also made some changes to make the game more realistic (at least I hope!). The K-truss doesn't collapse on itself anymore, so that's a step in the right direction. Also, the diamond shaped bridge that PlasmaMan posted on the fun-motion physics forums can no longer beat IMPOSSIBLY HEAVY! I challenge anyone to see if they can still beat IMPOSSIBLY HEAVY!

Now, what I'm most excited about is the new feature: Joint Monkeys! That's right, now you can hang monkeys from your bridge's joints. What could possibly be more fun? My best run has been 23 total monkeys with 7 hanging from a single joint.

I get this error in FireFox 3 Beta 5:

Silverlight Error:

I don't think Silverlight supports Firfox 3 yet.  It's too new.

I wish the were a bit of an explanation on how to build a good bridge.  I'm tying joints together, but I don't feel like I know what I'm doing otherwise.  On the plus side I've seen similar games, and this one works the best.

That is a good point and that is what I was hoping the Bridge Code feature would help with.  People have posted some interesting bridges over at the fun-motion physics forum:
