Re: Handling dynamics for bowling pins

Well the test works pretty well. I'll have to keep playing with it to get the right scale (a bowling alley lane is 1.05m x roughly 20m) but this is definitely a good starting place. I tried making the box 10x200 to approximate the scale but, as expected, this caused the pins to randomly fall over fr...

Re: Handling dynamics for bowling pins

Wow, that's great! I'll download that and give it a try later. Hopefully this does it for me. :)

Re: Handling dynamics for bowling pins

I tried modeling a plane that was subdivided a bunch but that didn't seem to help (and made the ball bounce as it rolled down the lane). I also tried making everything smaller and that seemed to make a bit of difference, but the pins still acted like they were responding to collisions right off the ...

Re: Handling dynamics for bowling pins

Well I solved part of the problem. Turns out somehow my visual model was 1 unit higher on the Y axis than my collision mesh. Not sure how since I modeled both on top of each other in Maya so they shouldn't have needed to be changed. However I applied a matrix for rendering to fix that shift and they...

Re: Handling dynamics for bowling pins

I had no idea an inertia tensor was generated for me. That's pretty nice. I am using a big box as my plane. Currently my lane is 21 units x 400 units (and I give the collision box a depth of 10 units). Could that scale be the issue? How would you suggest resolving this? Should I shrink my physics si...

Handling dynamics for bowling pins

I'm currently working on a little bowling demo to learn BEPU and am having some issues with the pins. I can't figure out exactly how to handle them: 1) Try to figure out a set of primitives that covers most of the necessary surface area. I figure that it could be done with a cylinder and about 8 or ...
