i’m wondering if there is a way to do two wheeled vehicles in the bullet vehicle wrapper. whenever i try, i fail miserably. i tried modifying the script so that it would support two wheels instead of four, and this seams to work, but my ‘bike’ keeps steering with both wheels instead of the front. it also falls over onto it’s side, but that doesn’t really have anything to do with the vehicle wrapper. if someone could figure that out too, that would be nice.
Then disable steering for the back wheel.
I would find the section that controls steering in the script and remove it for the back wheel.
