Hi Please Help Me... PxController Problem...!!!

I’m sorry. I can not speak English well.

I am having problems now.

this is my code.
my Player Object is CapsuleController.
/---------------------------------
m_pScene = pPxScene;

PxCapsuleControllerDesc PxCapsuledesc;
PxCapsuledesc.position = PxExtendedVec3(0, 0, 0);
PxCapsuledesc.radius = 5.0f;
PxCapsuledesc.height = 10.0f;
PxCapsuledesc.stepOffset = 2.f;

PxCapsuledesc.volumeGrowth = 1.9f;
PxCapsuledesc.slopeLimit = cosf(XMConvertToRadians(15.f));
PxCapsuledesc.nonWalkableMode = PxControllerNonWalkableMode::eFORCE_SLIDING;
PxCapsuledesc.upDirection = PxVec3(0, 1, 0);
PxCapsuledesc.contactOffset = 0.0001f;
PxCapsuledesc.material = pPxMaterial;
m_pPxCharacterController = pPxControllerManager->createController(PxCapsuledesc);

My stage map used a triangle mesh.
/------------------------------------------------------------------------------
PxTriangleMeshDesc meshDesc;

PxVec3* m_pVtxTex;
PxU32* m_pIndex;
_uint m_iCount;
m_iCount = CMeshMgr::GetInstance()->Get_MeshVtxCnt(m_uiObjNum);
m_pVtxTex = CMeshMgr::GetInstance()->Get_MeshPxVtx(m_uiObjNum);
m_pIndex = CMeshMgr::GetInstance()->Get_MeshPxIndex(m_uiObjNum);
meshDesc.points.count = m_iCount;
meshDesc.triangles.count = m_iCount/3;
meshDesc.points.stride = sizeof(PxVec3);
meshDesc.triangles.stride = sizeof(PxU32) * 3;
meshDesc.points.data = &(*m_pVtxTex);
meshDesc.triangles.data = &(*m_pIndex);
meshDesc.flags = PxMeshFlags(0);
PxDefaultMemoryOutputStream stream;
bool ok = pCooking->cookTriangleMesh(meshDesc, stream);
if (!ok)
return ;

PxDefaultMemoryInputData rb(stream.getData(), stream.getSize());
PxTriangleMesh* triangleMesh = pPxPhysics->createTriangleMesh(rb);
PxVec3 ScaleTemp = PxVec3(vScale.x, vScale.y, vScale.z);

//Scale
PxMeshScale PxScale;
PxScale.scale = ScaleTemp;
PxTriangleMeshGeometry meshGeom(triangleMesh, PxScale);

PxTransform _PxTransform(0, 0, 0);
m_pPxActor = PxCreateStatic(*pPxPhysics, _PxTransform, meshGeom, *pPxMaterial);
m_pPxActor->setName(name);
pPxScene->addActor(*m_pPxActor);
//------------------------------------------------------------------------

The problem I’m having here is that the controller is somewhat floating in the triangleMesh.

I don’t understand.

How do I get the controller to stick to the stage obects that surrounds the triangle mesh?

//example Pictures

      <------ this gap Why??????????

Hello,

I cannot see an actual picture with your post but I suspect the gap is just the “skin width” (a.k.a. contact offset) between the kinematic capsule embedded in a character controller, and the mesh.

How are you rendering the capsule? If you are just rendering the PxActor from the character controller, then this is not the volume used for collision detection and sweeps by the character controller module. You need to add the PxControllerDesc::contactOffset to the capsule’s radius.

You can try to set this parameter to 0.0 to see if it indeed makes the capsule touch the mesh (don’t do that permanently though, just to check whether this is indeed the problem).

This is the situation most similar to me.

How are you rendering your character’s capsule/box? Are you sure you use the “height” parameter correctly? Maybe you need to multiply it by two, as there’s often a confusion between what the “height” or “half height” means.

The capsule should touch the ground, as it does in our samples. You might try to check the samples and compare them to your app, to find where the difference comes from.

Otherwise, would you have a small repro that I could use? (maybe a small zip with a the minimum source code needed to reproduce the problem). The code above doesn’t show me enough to figure out where the problem comes from.

I received your reply.

I’m just using a character controller.

Player Object

variable

PxController* m_pPxCharacterController;

It is a character controller setting.

PxCapsuleControllerDesc	PxCapsuledesc;
PxCapsuledesc.position = PxExtendedVec3(0, 0, 0);
PxCapsuledesc.radius = 5.0f;
PxCapsuledesc.height = 10.0f;
PxCapsuledesc.stepOffset = 2.f;
PxCapsuledesc.volumeGrowth = 1.9f;
PxCapsuledesc.slopeLimit = cosf(XMConvertToRadians(15.f));
PxCapsuledesc.upDirection = PxVec3(0, 1, 0);
PxCapsuledesc.contactOffset = 0.1f;
PxCapsuledesc.material = pPxMaterial;
m_pPxCharacterController = pPxControllerManager->createController(PxCapsuledesc);

Character Controller Gravity Setting
The character controller spontaneously falls from top to bottom.

Object UPDATE Part

m_fFallvelocity -= m_fFallAcceleration * fTimeDelta * 50.f;
if (m_fFallvelocity < -1000.f)
	m_fFallvelocity = -1000.f;
m_pPxCharacterController->move(PxVec3(0, 1.f, 0) * fTimeDelta * m_fFallvelocity, 0, fTimeDelta, PxControllerFilters());

PxControllerState   m_pPxState;
m_pPxCharacterController->getState(m_pPxState);

if (m_pPxState.collisionFlags == PxControllerCollisionFlag::eCOLLISION_DOWN || 
m_pPxState.collisionFlags == PxControllerCollisionFlag::eCOLLISION_UP)
m_fFallvelocity = 0.f;

Object that creates the map (-> ground Object)

variable

PxRigidStatic *m_pPxActor;

Using TriAngle Mesh;
It is a Static setting.

PxTriangleMeshDesc meshDesc;

PxVec3*			m_pVtxTex;
PxU32*			m_pIndex;

_uint			m_iCount;

//Mesh vertex Count
m_iCount = CMeshMgr::GetInstance()->Get_MeshVtxCnt(m_uiObjNum);
m_pVtxTex = CMeshMgr::GetInstance()->Get_MeshPxVtx(m_uiObjNum);
m_pIndex = CMeshMgr::GetInstance()->Get_MeshPxIndex(m_uiObjNum);

meshDesc.points.count = m_iCount;
meshDesc.triangles.count = m_iCount/3;
meshDesc.points.stride = sizeof(PxVec3);
meshDesc.triangles.stride = sizeof(PxU32) * 3;
meshDesc.points.data = &(*m_pVtxTex);
meshDesc.triangles.data = &(*m_pIndex);
meshDesc.flags = PxMeshFlags(0);

PxDefaultMemoryOutputStream stream;
bool ok = pCooking->cookTriangleMesh(meshDesc, stream);
	
if (!ok)
return ;

PxDefaultMemoryInputData rb(stream.getData(), stream.getSize());

PxTriangleMesh* triangleMesh = pPxPhysics->createTriangleMesh(rb);

PxVec3 ScaleTemp = PxVec3(vScale.x, vScale.y, vScale.z);
//Scale
PxMeshScale PxScale;
PxScale.scale = ScaleTemp;
PxTriangleMeshGeometry meshGeom(triangleMesh, PxScale);
PxTransform _PxTransform(0, 0, 0);
m_pPxActor = PxCreateStatic(*pPxPhysics, _PxTransform, meshGeom, *pPxMaterial);
m_pPxActor->setName(name);
pPxScene->addActor(*m_pPxActor);

That’s all !!

However, when the character controller falls under gravity and is closed to the ground, it does not stop but stops above a certain distance.

I really can not understand.!!!

Have you tried visualizing in PVD(PhysX Visual Debugger)? This would let you see exactly what PhysX is simulating. You may find that what is rendered in PVD looks like it’s touching the ground. If that is the case, then the issue may be the following:

(1) The halfHeight value is the height of a line segment that is the basis vector for the capsule. The full height of the capsule is halfHeight + 2*radius. If the thing you are rendering is not as big as the thing PhysX is simulating, your render will look like it’s floating.

(2) The location of the capsule is defined at center of the capsule. Please ensure that the model you’re rendering is also centered around the same space. If it isn’t (say if the geometry is centered around the base of the capsule/box), you would need to compensate for this somehow when assigning the PhysX transform to your render object.

If you take a look in PVD, you will probably see that the capsule/box is touching the ground. Alternatively, you could also confirm this by placing a very small dynamic object on the ground near your character and have it walk towards it. If the character can push the object even through the shape you’re rendering seems like it is floating above the object, that’s a good indicator that the problem is that what you’re rendering doesn’t match what PhysX is simulating.

Hope this helps.

Thank you for the reply.

(1)
I was already using PVD(PhysX Visual Debugger). Already in PVD, the Character Controller was slightly floating from the ground.

The Character Controller is affected by gravity and falls down, and the Character Controller stops at a certain height before it closes to the ground.

However, when using an object using the Dynamic Actor, the object is gravitationally affected and falls down to the ground.

Dynamic Actor is very close to the ground.

If so, is there a problem with the Character Controller?

I can not understand.
