Hello,

is it intentional to call addConstraint(pGen6DOF, true) with true as its second, disableCollisionsBetweenLinkedBodies parameter, and this way disabling collision between body and body2 ?

Hello,

how did you create the constraint and add to your world?

Hello,

it also happens for me, and as far as I can remember e.g. strings are stored in such chunks (as arrays of char-s), and they do not have an own DNA ID.

Sorry, I think bullet is not too well documented...

Hello,

I think you might get some kind of information from the TranslationalLimitMotor. You could try something like this: Hope this is what you need.

Hello! I am not really familiar with OpenGL and glm, but for me it seems you are using the wrong function of btTransform. getOpenGLMatrix gets the information from the btTransform and writes it to the given parameter, in your case cursor.m_modelMatrix. I think you intended to do it the opposite way,...

Hello, both approaches are OK. The difference is that with applyCentralForce you need to apply a force for a period of time to really have the effect of throwing (so it is usually not enough to only call it once). During this period the ball gains speed because of the applied force. On the other han...

Hello!

The source itself is in the BULLETDIRECTORY/Extras/Serialize/makesdna subdirectory.

There you can also find a CMakeLists.txt, but if you are using VS you can also create a project for makesdna by hand as it only uses a couple of files.

Hope that helps.

I think you could try setting the angular factor to 0 on that rigid body using btRigidBody::setAngularFactor.

I do not know if I understand the original problem correctly, but if all you need is dynamically changing gravity then could use the setGravity function of btRigidBody in every step before (or after) every stepSimulation. At this point you can retrieve the position of your car or plane with e.g. btR...

I have found a bullet issue which explains a more or less similar situation, maybe the information there could also help you, please take a look at it: https://code.google.com/p/bullet/issues/detail?id=687&colspec=Modified%20ID%20Type%20Stars%20Status%20Owner%20Summary There Erwin states: Before...

I think first you should take a look at the App_SoftDemo demo project of bullet. There are a lot of small demos integrated into this project. I think demo #7 might be useful for you (you can change demo number with the [] keys), where a cloth mesh is lying/hanging on a capsule shape. You can find th...

I am not familiar with RaycastVehicle so my answer might not be 100% relevant but I know for sure that btGeneric6DofConstraint doesn't really like 90 degree rotation on its Y axis. Please see detailed description of btGeneric6DofConstraint in bullet online help: Angulars limits have these possible r...

Hi, has anybody already bumped into btAssert(found) in btSequentialImpulseConstraintSolver::solveGroupCacheFriendlySetup function? We have created a ragdoll and for a "special" experiment we had to turn off collision on its rigidbodies. We used a picking constraint very similar to the one ...

btMotionState setWorldTransform supplies world transformation. If you have an Ogre::SceneNode attached to the root scene node (root scene node in the "world center"), then you can directly use the position and rotation information from this world transform in e.g. Ogre::SceneNode::setPosit...
