ok so i've added a new vehicle type.
For now its just a stdwheeled copypasta.
however it keeps givng me this error message.
any idea why?

I will keep working on this, if I manage to find out, I will let you know.
However if anybody knows...let me know
Or if someone could give a more detailed explanation of how to go about adding new movement types.
much appreciated.

I'm just having the same problem.
I found that we have reference our new movement class in GameFactory.cpp.
Now i have to delete "duplicate" like struct and anything else to be able to compile, and then i think it will be ok.

So not it's not enough, i still have this error, event after having referenced my new class in gameFactory.

And we don't hava acces to CVehicle class, it's very hard to learn this engine without detailed documentation or cry devs on the forum.
