hi.

i have this error linker when i try to compilie

error LNK2005: "public: static class hkTypeInfo const * const * const hkBuiltinTypeRegistry::StaticLinkedTypeInfos" (?StaticLinkedTypeInfos@hkBuiltinTypeRegistry@@2QBQBVhkTypeInfo@@B) already defined in CTerrain.obj

i dont write anything with hkTypeInfo in Cterrain.h

how do i solve it. thanks

[ask]how to generate havok heightfield using vertices x y z

Wed, 25 Nov 2009 00:00:06 -0800

hi.

how do i generate havok heightfield using vertices x y z.?
i am using directx, and have generated the heightmap using raw file. and i have the vertex buffer.

the vertex buffer has this xyz values.

how to convert those xyz value to suit the variable needed for HeightFieldShape(ci, heightData);

in the sample i found these code

for (int x = 0; x < xRes; x++)
        {
            for (int z = 0; z < zRes; z++)
            {
                hkReal dx,dz,height = 0;
                int octave = 1;
                // Add togther a few sine and cose waves
                for (int i=0; i< 3; i++)
                {
                    dx = hkReal(x * octave) / xRes;
                    dz = hkReal(z * octave) / zRes;

                    height +=  (5 - (i * 2)) * hkMath::cos(dx * HK_REAL_PI) * hkMath::sin(dz * HK_REAL_PI);
                    octave *= 4;
                }

                // Convert to 16 bit 
                m_heightData[x*zRes + z] = static_cast ( hkUint16(-1) * (height + 10.0f) / 20.0f );
            }
        }

so how do i do it with the already generated xyz from raw file??

thank you

Crash when loading skeleton

Tue, 24 Nov 2009 14:33:16 -0800

I am trying to load a skeleton into my app without the demo framework and I cannot seem to see why this crashes

void CreateSkeleton()
{
hkLoader* m_loader;
hkaSkeleton* m_skeleton;

// Load the data
m_loader = new hkLoader();

wstring MediaDirectory = L"../../Media/";
wstring HavokDirectory = L"Resources/Animation/HavokGirl/";
wstring FileName = L"hkRig_L4101.hkx";// hkRig.hkx hkRig_L4101.hkx
wstring FinalFileName = MediaDirectory + HavokDirectory + FileName;

hkRootLevelContainer* container = m_loader->load( JWStringToString(FinalFileName).c_str() );

if(container != HK_NULL)
MessageBox( NULL,L"You got the container",L"Error", MB_OK );
else
MessageBox( NULL,L"No container loaded",L"Error", MB_OK );

hkaAnimationContainer* ac = reinterpret_cast( container->findObjectByType( hkaAnimationContainerClass.getName() ));

if(ac && (ac->m_numSkeletons > 0) )
MessageBox( NULL,L"You got the skeleton",L"Error", MB_OK );
else
MessageBox( NULL,L"No skeleton loaded",L"Error", MB_OK );

m_skeleton = ac->m_skeletons[0];

}

It always crashes here:
hkaAnimationContainer* ac = reinterpret_cast( container->findObjectByType( hkaAnimationContainerClass.getName() ));

even though the app reports that the container is loaded properly...

I believe that the source from the demos might be outdated because in the source it loads hkRig.hkx but that file doesnt exist in the resources folder. I tried to substitute hkRig_L4101.hkx instead but i still get the crash.

Any help would be appreciated ;).

Edit: I figured the demo(Api/Playback/SkeletonDemo) would be the easiest place to start for animation since all it does is load a skeleton but if anyone has an tips on a simpler example i would be glad to know.

Havok Content Tools Linear and Angular Damping

Tue, 24 Nov 2009 10:41:32 -0800

I am exporting an hkx file with a rigid body which I am controlling through forces in my demo. The linear and angular damping are not being exported by the content tools. Max linear veloctiy (as well as angular) are not being exported either. I have double checked that with the XML filter.

Vehicle warning: The force feedback multiplier value is large

Tue, 24 Nov 2009 08:44:33 -0800

Hello, I'm using the default havok vehicle and I'm getting this warning:

The force feedback multiplier value is large - the forces being applied to objects the vehicle runs over will be clipped.

Which parameters can be causing this?

How to Deactivate the World and stop the collisions?

Tue, 24 Nov 2009 00:59:54 -0800

Hello,
I am trying to implement a 'FlyCheat' for the CharacterProxy in a game. When I press button 'p' on the keyboard I want the world to get deactivated and I want no collisions to take place. Now the user can control the CharacterProxy and he can move freely (Something like a 'GOD' mode where he can go pass anything e.g. walls) And when the user presses 'p' again I want the world to get reactivated and collisions to start working.
Now, Let me tell you what I have done. I have already created a hkpWorld as follows:
void GameObjectManager::CreateWorld()
{
{
int stackSize = 0x100000;
stackBuffer = hkAllocate( stackSize, HK_MEMORY_CLASS_BASE);
hkThreadMemory::getInstance().setStackArea( stackBuffer, stackSize);
}

m_WorldCinfo.m_simulationType = hkpWorldCinfo::SIMULATION_TYPE_CONTINUOUS;
// Flag objects that fall "out of the world" to be automatically removed - just necessary for this physics scene
m_WorldCinfo.m_broadPhaseBorderBehaviour = hkpWorldCinfo::BROADPHASE_BORDER_REMOVE_ENTITY;

// 2 lines added for char class
m_WorldCinfo.setBroadPhaseWorldSize(10000);
m_WorldCinfo.m_gravity.set(0, -9.8f, 0);
m_WorldCinfo.m_collisionTolerance = 0.1f;
m_PhysicsWorld = new hkpWorld(m_WorldCinfo);

m_PhysicsWorld->m_wantDeactivation = false;
// Register Collision agents
hkpAgentRegisterUtil::registerAllAgents( m_PhysicsWorld->getCollisionDispatcher() );

}

//Now I call a function named flyCheat() on keypress 'p'

void CharacterProxyObject::flyCheat()
{
//physicsWorld is the same hkpWorld used during creation
physicsWorld->m_wantDeactivation = true;

}

However this doesnt seem to work. The world is not getting deactivated. Also can you please let me know how the collisions in the physics world can be stopped and later resumed.

Thanking you.

Ajinkya

How to get the angle of the hinge constraint

Mon, 23 Nov 2009 05:04:00 -0800

I used a motor to drive the hinge constraint. Now I wanna know how to get the relative angle between the two bodies, not the target motor angle.

If this kind of API is not provided, is there anything useful tool to compute the relative angle?

Thank you in advance.

Using the visual debugger with a hkpVehicleInstance in the World crashes my app

Sun, 22 Nov 2009 11:37:59 -0800

Hello,

I've been trying to get a simple vehicle into my application, but whenever I add it to the world my application crashes, but only if I use the hkVisualDebugger::step(), if I comment this out, it works and the chassis also colldies with a box in the scene (I 'confirmed' that by logging the Y (height) of the chassis through some time).

Here is the code I use to add my vehicle to the simulation:

// m_vehBody is the rigid body I use for the chassis
	m_vehInst=new hkpVehicleInstance(m_vehBody);

	// This creates all elements that hkpVehicleInstance requires and setups their values 
	m_vehicle.BuildVehicleMain(m_world,*m_vehInst,0.4f,hkVector4(0.9f,-0.1f,1.1f),hkVector4(0.9f,-0.1f,-1.3f));	

	// Add to simulation, is this ok?
	m_vehInst->addToWorld(m_world);
	m_world->addAction(m_vehInst);

How do I compare two hkVector4's?

Sat, 21 Nov 2009 16:35:50 -0800

Hello,
I have a problem in comparing two hkVector4 positions. The thing is I am trying to implement a 'teleporting' functionality for the CharacterProxy. So I basically want to compare the current position of the CharacterProxy and a specific position in the world. Well I am using the following code:

void CharacterProxyObject::teleport(hkVector4 &checkPosition,hkVector4 &teleportPosition)
{

hkVector4Comparison a;

a.MASK_W;
a = checkPosition.compareEqual4(getObjectPosition());
//getObjectPosition gets the current position of the CharacterProxy
}

Now I am not able to figure out how can I check for the individual x,y,z components?
Can you please help me out with this?
Thanking you.

P.S.: Please excuse me if this question has been answered before as I am new to this forum.
