Problem with Newton Physics

Jun 1, 2009 at 12:08 AM

Hi,

I'm trying to set WorldSize in Newton Lib, but when i set it shows a message:

System.AccessViolationException was unhandled
  Message="Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
  Source="NewtonWrapper"
  StackTrace:
       at NewtonDynamics.Newton.NewtonSetWorldSize(IntPtr pNewtonWorld, Single[] pMinPoint, Single[] pMaxPoint)

  InnerException:

My code

NewtonPhysics physics= new NewtonPhysics();
physics.WorldSize = new BoundingBox(new Vector3(-400f, -200f, -400f), new Vector3(400f, 200f, 400f));

 

Did anyone try this?

You need to initialize the physics engine before doing anything with it.

If you do scene.PhysicsEngine = new NewtonPhysics(), then scene class automatically calls the Initialize() function, but if you just do NewtonPhysics physics = new NewtonPhysics(), then you need to call Initialize() yourself.
