I creating a pinball game and I have most of my code worked out, except for one thing.  I'm not sure what to use for the bumpers in the game.  I have 4 bumpers (2 circles, 2 polygons).  I've tried using both fixed linear springs and fixed angular springs, but after all my efforts of trying to tweak them (by changing mass, dampening constant, and spring constant) and make them stiff.  I can't get them to work.  I've heard of using slide joints because there stiffer than springs, but I'm not sure.  What's the best way for me to go about this?

I actually have hit a similar road block for a pinball-like game I am working on.  Any ideas?

Are the bumpers not static? What kind of movement should they perform?

The bumpers are static, but I don't know how to model them using the physics engine.  They will have a circular geometry, but I'm trying to get the bounce effect off of the bumper, and not just a collision, if that makes sense.

You want it to bounce more? Set the RestitutionCoefficient on the bumper to make it bounce more. Pass it a value between 0 and 1. 0 is no bounce and 1 is a perfect bounce.

Thanks a lot, genbox!  That worked great, and gave just the effect I needed.

Hey ZachTheRiah, I just wanted to know what platform your pinball game is for?

I have made it for Windows.  (It's more of a "pinball-like" game--Plinko, from The Price is Right).
