[Solved] RagDolls penetrating static TriangleMeshShapes

Looking for a little help for a good solution with this problem in our game. It looks to me like a flaw in the way Bullet handles collision on constrained objects but could be a small object problem. Basically we have a complex rag doll setup for our main character, built entirley from btCapsuleShap...

Re: problem loading mesh from .bullet file

Dynamica is availabe for Max now. This is an excellent fix :) Thank you VicariousEnt, now I need to dig up the code I saw on converting a rigid body to a btBvhTriangleMeshShape and I am in serious buisness! 8) The last release of Dyamica actually has code in it for this but a bug kept it from being ...

Re: Bullet development updates

That would be fantastic! If another release with bug fixes were to come out fairly soon I would be able to adopt it into our project before it ships.

Re: Questions about joints, usage and design of Bullet...

Oh one other thing. Maybe its too minor to bother adding to the issue tracker or fixing it may cause other issues, but the twist limit debug rendering doesn't work when the rigidbodies its attached to are set to Static. The 2 swing span limits render fine, its just the twist limit. Looking though th...

Searching for some ConeTwistConstraint answers myself and came across this thread. Its not too old so I'll answer what I can with my experience thus far. Alot of these questions I figured out by reading source, testing demos and trail and error. Most of these could be easily answered by comments in ...

Re: Bullet 2.78 released: FractureDemo, CCD,SAT contact clip

Awesome!

Will a 2.78 Dynamica release be far behind? I would assume we'd need a new build of it to take advantage of the improvments to the .bullet file format. Hopefully full primitive support (capsules & cylinders) and the cone twist contraint will make it into that.

Re: Small Dynamica and Serializer feature requests

As requested I've added my fixes and requests to the google code Dynamica Project. I've included SVN Patches for the code changes. The fix to make btBulletWorldImporter remove objects from its DynamicWorld before deleting them is here... http://code.google.com/p/dynamica/issues/detail?id=16 The cras...

Re: Small Dynamica and Serializer feature requests

Sorry to be a pest, but I wanted to discuss one more issue. I ran into a crash in the btGimpactTriangleMeshShape code during debug rendering and collision tests. This issue has been raised in a couple threads already so I posted my fix to it in one of them... http://bulletphysics.org/Bullet/phpBB3/v...

Re: problem loading mesh from .bullet file

Ok, so I ended up running into this crash problem myself and decided to come up with a proper fix for it instead of a work around. The crash is basically from a sort of design flaw in the btGimpactTriangleMeshShape collision primitive. If you look at the GimpactTestDemo it illustrates how this class...

Re: Serialization breaks determinism?

At this point player B now has 100B and so he de-serializes 100A that he downloaded from the server and compares the two states. I would have expected 100A and 100B to be identical but they are ever so slightly divergent. I'm not sure I entirely understand your main problem, but in regards to the q...

Re: Small Dynamica and Serializer feature requests

Perhaps it could be an optional parameter in the WorldImporter loadFile() function? Yes, we can add a flag/setting to the btBulletWorldImporter, to create collision objects for objects with mass 0. This will of course require the btCollisionObjects to be added to the DynamicWorld as well as the Rig...
