Hi

I´m from germany thus english aren´t my native language.
But I hope you can understand me.

Here are some background information:

I´m programming a game and have some good experiences on C++
and PhysX and irrlicht, but irrlicht doesn´t satisfied me so I
changed to ogre.

I´ve changed my renderer engine from irrlicht to ogre - everything works.
( It was a lot of work, especially the trimesh cooker, because I didnt know ogre before)
I´ve made a new project for this conversion.

So, after changing my renderer engine, I wanted to add my entity class, which includes the
PxController. I´m using the PxCapsuleController and I can move it, it collides with
each triangle or primitive shapes. <- So that works great.

So far, in irrlicht works the collision perfect, with PhysX 3.1, 3.11, 3.2 Beta 1 or 2.


I´ve got some strange bugs and I dont know why and how it works.

If a PxRigidDynamic collides with my controller there are a big bug / bad behaivor of it.
The PxRigidDynamic moves my controller !!!! ( Without code it, that cant be true! )
And if I´m deleting the PxRigidDynamic while he is
moving my controller, it crashes sometimes - but its not findable because it crashed in
PhysX3CharacterKinematic_x86.dll at the procedure controller->move(..) !
( No other debug information are available. ! ) - it worked in irrlicht!

So, I though there are maybe a bug in my entity class, but it works 100% in irrlicht.
I can create some primitives and a controller if I push some keys to test it.

( No inherties from other classes )

SO- that same bad behaivor - each collision works, BUT the PxRigidDynamic can push
my controller around, it doesn´t matter if it was may entity controller or a "fresh"
clean controller. AND each controller CANT push any objects!! There will be pushed
by an object, and moves along while the object is moving. BUT sometimes the controller
are able to push a PxRigidDynamic for some short distance.

Example 1: Sometimes or seldom I can push a PxRigidDynamic when I try to move it ( ran against it) and change the velocity direction ( 3rd person camera).

Example 2: I can push the PxRigidDynamic while there are not on the ground - only testet while the objects are falling down, than I can move each PxRigidDynamic.

Other information:

I use PxSimulationFilterCallback and PxSimulationEventCallback and PxUserControllerHitReport
but it doesn´t matter if I "commented off" or returns only the needed values.


BUT: Another strange thing is, that the project is almost 1 : 1 converted,
only the differences between irrlicht and ogre are changed.

So, my question is how can I fix that? And how can that be possible?

I´ve tried it with Physx 3.2 Beta 1 and 2 - but both doesn´t work in ogre,
but perfekt in irrlicht. HOW CAN THAT BE?

Here are the code how I create the controller and PxActors...

// Rigid Actor
PxRigidDynamic* mActor = mPhysic->getSDK()->createRigidDynamic(PxTransform(CConvert::toPx(Vector3(50,0,0))));
PxShape* shape = mActor->createShape(PxBoxGeometry(PxVec3(1.f)),*mPhysic->getSDK()->createMaterial(0,0,0));
mActor->userData = new CPhysicActorUserData(mActor,COLLISION_GROUP_INVALID);
// mActor->setMass(1); // Doesn´t matter
mActor->setRigidDynamicFlag(PxRigidDynamicFlag::eKINEMATIC,false);
mPhysic->addUserDataToShapes(mActor);
mPhysic->getScene()->addActor(*mActor);

//Controller
PxCapsuleControllerDesc desc;
desc.material = mPhysic->mCollisionMaterial.mDefaultMaterial;
desc.height = 5;
desc.radius = 4;
desc.position = PxExtendedVec3(0,-10,0);
desc.scaleCoeff=1;
desc.climbingMode = PxCapsuleClimbingMode::eCONSTRAINED;

Con = mPhysic->getManager()->createController(*mPhysic->getSDK(),mPhysic->getScene(),desc);




I hope you can help me..
