some difficulties upgrading to public NGD 2.0

Postby Auradrummer » Fri Jan 23, 2009 6:33 pm

Me again ...!!!!!!!!

I upgraded my Newton Dynamics to the public version. I`m not having big problems, really, but some doubts:
1. The functions I set as callbacks usually asked me two args: (NewtonBody* body, dFloat timestep). Now, they are asking me for a third parameter, an int.
First: what happens if I declare anything instead of timestep in the function? I`m not using this timestep anywhere.
Second: what is that int?

2. I made my car based in the old `MonsterTruck` example. The structures Axle, Tires and the car are returning the error `Cannot allocate ... abstract type` and ` because virtual functions are pure within ...` and so on. Someone have any tip?

I`m still working over those questions, but if is a natural issue, I think some tip could make my work easier.

Thanks again to everybody!

A lot of the callbacks have an extra parameter for the thread now.

Thanks Werks, but I mean 'what I have to pass there?'

Considering it's a callback, you don't pass anything, Newton does. It simply tells you which thread index is currently calling this callback.
