Hi all: Collision group and collision filter seems not working between kinematic rigidbody and dynamic rigidbody collision. I also set collision flag of kinematic object to CF_NO_CONTACT_RESPONSE， but dynamic object still collid with kinematic object, and it got rebounded. So, what should i do to av...

Thanks for your replay, drleviathan and Flix. The V-HACD project looks great. I'm going to use 64 boxshapes and a bottom shape, all rigidbody, no compound shape. . The reason i believe trigngle mesh is expensive is that if i use it, the aabb of arena will intersect with every single aabb in this are...

I have an arena which might look like this: http://oi60.tinypic.com/nxt6o1.jpg I believe it's too expensive to use Triangle mesh. I'm thinking to use static plane to represent floor, and 64 box shapes to represent the wall.(every box for a section of wall). I have never worked in this area, i don't ...

just use body->setWorldTransform() not motionstate->setWorldTransform(tf); Thanks marios. It shoud be done as you said. Not via motionstate. And to drleviathan: I don't think it's a good idea to write this code in motion state. mBody->setWorldTransform(worldTrans); I think for dynamic object, Motio...

Hi drleviathan. I use ogre with bullet, this is my motion state: virtual void getWorldTransform(btTransform &worldTrans) const { worldTrans.setRotation(toBt(mSceneNode->_getDerivedOrientation())); worldTrans.setOrigin(toBt(mSceneNode->_getDerivedPosition())); } virtual void setWorldTransform(con...

I want to change position of dynamic object manually, this is my code. body->activate(true); btMotionState* ms = body->getMotionState(); btTransform tf; ms->getWorldTransform(tf); tf.setOrigin(btVector3(x, y, z)); ms->setWorldTransform(tf); It doesn't work, the object will flash back to it's origina...

Thanks c6burns

Hi, i'm using bullet(2.82) terrain with ogre1.9 It works fine except it takes too much performance to debug draw wireframe of terrain. The fps drop below 5 if i toggle draw wireframe, i can barely move my camera. Is there a way to disable debug draw of terrain ? :?: For most of time, i just want to ...
