Acrobatic and Slide vehicle

[jcarew]

Hi, I found some problems in my vehicle (I use Bullet Vehicle class for them).
1. When car stay on slope ground, my vehicle slide down, I set break force on max, but it doesn't help. How can I stop my vehicle on slope ground? eg. when cars waiting for start a race.
2. When I smash (speed is around 150km/h with vehicle size: 2.0x1.0x1.5 Bullet units -ConvexHull for car + Cylinders for wheels) in other vehicle or in wall, my car go up (on 10 or more meters) and do funny acrobatics in fly. How can I decrease this "effect". I think, when I smash in wall, my car should stop (eg. in most racing games), but vehicle go up. I try with Friction for vehicle body, this is ok, but when car jump, on landing stage friction "effect" is also visible, because floor of my car is in contact with ground, because suspension is so soft and I don't know how create harder suspension...
Thanks all for help.

Hi,

when you disable the gravity for the 'race start period' you should stop sliding as no force is acting.
