Hey all!
I am really struggling with this error, I am trying to setup a custom torque and force feedback but it crashes when I run it. It crashes with a standard "Instruction at xxx referenced memory at yyy. The Memory could not be read"
On debugging I find it crashes in this function:
This comes from my Character Initialisation function:
I have a well defined world that I have been using, I create the col just before I create a character:
At the moment, as you can probably tell, I don't fully understand alot of things, so alot of things are being hacked together just to see it working and then I was goign to refine things as I go along, at the moment I have no idea why this isn't working.
One thing I did notice when debugging though, compared to my friends who works fine, is that if I step into my newtonWorld variable, and then into m_leavefeedback, down past the two boost functions I come to a 'vtable' variable: "Error expression could not be evaluated". I don't know if this has any effect on what I am trying to do, but it is the only difference between mine and my friends whose works.
I have searched the forums and such already, so any ideas at all will be muchly appreciated, because I am completely stumped

void setCustomForceAndTorqueCallback( ForceCallback callback );

}This comes from my Character Initialisation function:

thisBody = new OgreNewt::Body(mWorld,col,0);
thisBody->setCustomForceAndTorqueCallback<Character>(&Character::CharacterForceAndTorque, this);
return thisBody;
}I have a well defined world that I have been using, I create the col just before I create a character:
col = new OgreNewt::CollisionPrimitives::Ellipsoid(W,Vector3(10,30,5),Quaternion(1,0,0,0),Vector3(100,0,100));At the moment, as you can probably tell, I don't fully understand alot of things, so alot of things are being hacked together just to see it working and then I was goign to refine things as I go along, at the moment I have no idea why this isn't working.
