I am applying the force as follows:

car->AddForce(vector*force);

I have also tried car->AddRelForce(vector*force);

but the car either moves in funny directions, or towards the axes.

Hi there,

I want to know how I can get the vector which points in the direction that an object is pointing, so that
I can apply a force in that direction.

I have tried :
car->GetTransform()*CS_VEC_FORWARD;

and
car->GetOrientation()*CS_VEC_FORWARD;

and
car->GetTransform().Other2This(CS_VEC_FORWARD);

but none of these seem to work, the force seems to be applied along the world axes, not in the direction that the car faces!

can you help?

The second code block i pasted shows where i initialise levelmeshes.
I can use it within that function with no problems, it is when I try to use it after this outside that function that I get a segfault.

Any ideas?

Kate

Hi there

levelmeshes is a global declared as

Code:

csRef<iMeshList> levelmeshes;

The following function is supposed to initialise levelmeshes and perform some stuff on it.
The function itself runs fine, but when I try to use levelmeshes later on in the code, I get a segfault as though it has not been initialised. Im guessing this is something to do with the fact that levelmeshes is initialised only within the scope of this function?

I also tried to return the raw iMeshList pointer and assigning it to a csRef outside the function but this didnt work either.

Your help with this would be much appreciated!

Code:

void Game::InitialiseLevelColliders()
{
  levelmeshes = engine->GetMeshes(); //initialise levelmeshes

  for(int i=0;i<levelmeshes->GetCount();i++)
  {
     //Do stuff with meshes - works ok
  }
}

Hi there,

I cant seem to access any of the bleeding edge docs at the moment. Could you tell me when this is likely to be resolved?

thanks

Hi there

I have made some changes to a plugin, and would like to recompile just that plugin without having to recompile the whole of CS again. Can I do this easily? If so could you tell me how?

Its the cs ODE plugin that I have changed, not ODE itself.

regards,
Kate

i take it this means no clues ?

any advice on this would be much appreciated,

regards,

Kate

that is correct.

With regards to the colliders, your final line:

Code:

m_app->GetDynSys ()->RemoveBody (m_body)

;

will remove the iRigidBody, not just the collider. Im not sure that this is what you want to do?

Code:

m_body->DestroyColliders ();

should remove the collider box from the iRigidbody, you could try calling

Code:

m_body->Update();

afterward.

Hi there,

the LCP error is harmless but appears to be some kind of bug in ODE. I can get hold of a patch to fix the bug if you want it?

I understand how to position the particle mesh, what im not sure about is how to find out the point where the two iRigidBody objects actually collide?

Looking at the API I cant seem to see any methods that let me find this out for a pair of iRigidBody or iDynamicsSystemCollider objects.

Kate

Hi there,

I have implemented some collision callbacks that generate a temporary particle effect when my car
collides with another object.

Could you give me some idea as to how I can position the particle effect specifically at the point of collision?
