Problem after updating from Newton 2.00 to latest from SVN

[TheDushan]

Hello guys.
I am expiring one problem after updating code from Newton 2.00 to latest from svn. [rev.r1155].
While my application is working on Newton 2.00 after updating it to latest revision from svn.
I am experiencing some problem, and I don't know is that Newton problem or problem with my code.

Am I using [coreLibrary_200].

I have uploaded two photos of my problems.

Thanks

you are not releasing the collisions afte you asigne then to a body

I had the same as in screenshot #1 after the update.
The app worked, but when closing it i got the same error msg.
When starting to play around with newton i was too lazy to care about proper deallocation.
Adding this 2 lines to my world object destructor solved it for me:

NewtonDestroyAllBodies (world);
NewtonDestroy (world);

The more dense error checking in actual newton is a good thing, as it helps to find your own mistakes.
You'll be warned if you generate NaNs, for example.

Hi Dushan, i've got your PM.

It seems in CMod_PhysicsAddEntity(sharedEntity_t * gEnt) you are not realeasing the collision, like you do correctly at generation of the static bsp model. Or is the release elsewhere?

Two other things i've found:
You call NewtonCreateBody (something, something, NULL)
If i use NULL in my app, i get a crash. Use the transformation matrix at creation instead.

Most important: It seems you use the timestep for newton based on fps. This is bad, as it needs a fixed timestep.
In practice, you should make steps at 60 Hz, and interpolate between actual and previous physical states for the rendering.
