When using the car level make sure that your car is aligned the same way as the one in the sample level. Also make sure that the car is slightly above the floor and not inside it at startup. Finally download the latest GameStudio beta from the Updates forum.
I ask because I was making the game with A6C and Newton, I bought this days (get yesterday my key) the A6 Pro to use the A6 Physics and I am finishing one Demo to send to my client. I never use the A6 Physics before and I am lost , It appears to be very different from newton, but I need the A6 Physics to save the level and have All compatibility with the Engine, not possible using the newton because it is a dll and all tries that I make to save a level it not save the physics.
I apreciate very much any simple example for I get fast the physics used in cars from A6 Physics like interation of body and tyres, any detail like position to use the model in MEd and this thinks.
