AddPointForce

[JoshKlint]

I know this was discussed previously, but I can't seem to find the right topic.

Does my equation for applying a force at a specific position look correct? It seems wrong to me that nothing is being subtracted from the force value:

Code: Select all

void Entity::AddPointForce(const Vec3& force, const Vec3& position)
{
   Vec3 torque = position.Cross(force);
   torque.x = Degrees(torque.x);
   torque.y = Degrees(torque.y);
   torque.z = Degrees(torque.z);
   AddForce(force);
   AddTorque(torque);
}

No. You need to get the center of mass and substract for the position.
There is a function in the sdk that does that.

You can check the source.
