They're inside bullet-2.75/msvc/8 for visual studio 2008 or /71 for 2005

libbulletcollision.vcproj
libbulletdynamics.vcproj
libbulletmath.vcproj

that wksbullet.sln file also builds those projects along with the samples.

You should be able to get away with adding just a btCollisionObject, though i haven't really tried it. For trigger zones in my game, i just use a rigidbody with CF_NO_CONTACT_RESPONSE and CF_STATIC_OBJECT flags set.

Okay, so the problem is no longer with the accumulator, but with waking objects up. You shouldn't need to wrap your accumulator around your remove code. You may have to do something where you activate all your objects if you remove an object. Do you have your own list of objects? pseudocode: void Re...

You're suffering from a problem called temporal aliasing. Even though you're using getWorldTransform, which supports interpolation, you're passing in a fixed time step so bullet doesn't interpolate (because it doesn't need to). If you pass in FrameTime to stepSimulation, the problem will go away. Of...

have you tried a simple cube/sphere? seems like there was some tricks i had to do to get it work, but here's my relevant code: dfCollisionShape *ZeroShape = NULL; ZeroBody = new dfRigidBody(0.0f, NULL, ZeroShape); dfTransform Rotation; Rotation.setIdentity(); ZeroBody->setWorldTransform(Rotation); ....

isn't it a little redundant to pass the start and end vector twice when you need to raycast the world? i.e. btCollisionWorld::ClosestRayResultCallback Result(Start, End); PhysicsWorld->getCollisionWorld()->rayTest(Start, End, Result); I think rayTest() should only have one parameter, ClosestRayResul...

Cool demos! I think that the webskategirl is more of a hoverboard simulation rather than a classical skateboard simulation. It seems like it has trouble going up the ramps though, since it's using a ray spring. I think that if you used a sphere to model the board, it could roll up the ramps smoothly...

I'm trying to create a skateboarding game with bullet physics. It seems like there are two ways to go about it: 1. Use the vehicle raycaster. 2. Use a regular shape (box or sphere) and constrain its movement to a vertical plane. I'm trying the second approach, since it seems like the vehicle method ...

Better, simpler, more up to date demo here:

Well for some reason my callstack gets corrupted. The IDE gives me the error: Windows has triggered a breakpoint in irrlamb.exe. This may be due to a corruption of the heap, and indicates a bug in irrlamb.exe or any of the DLLs it has loaded. The output window may have more diagnostic information An...

Hey Proctoid.

You're right, i meant to say delete constraints before rigid bodies. (hint: don't post after poker night and drinking)

So i guess the proper way is to delete constraints first. It's weird that it was working (by working i mean not crashing) up until 2.54.

Thanks

With the new 2.54, i'm experiencing a new bug when deleting constraints after rigid bodies. Basically: i'm getting a crash inside VS2005 when i delete a constraint after a rigid body. However, i can't reproduce the crash inside a test crash, or outside debugging inside VS2005. Not very convincing is...

cool thanks for adding this to 2.54 Erwin

In my game, i need to raycast only on certain objects. Since there was no easy way to do this, i decided to add a collisiongroupmask to the rayTest function. void rayTest(const btVector3& rayFromWorld, const btVector3& rayToWorld, RayResultCallback& resultCallback, short int collisionFil...
