hello
i saw Citroen C4 Game in this post :
http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=222889&page=1
it is very good in graphic and physic.
i try to use "3DGS BASIC PHYSICS CAR TUTORIAL Version 0.3" in post:
http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=280628&page=2

and i have two problem

1:in Citroen C4 car moves so fast . when i increase my car speed my car dosen't go fast even with 300 in speed and i have problem in physic(my car goes up and down)

2:in Citroen C4 if you collide to any object with any speed car just decrease speed and stay on the ground but when my car collide with other objects my car goes up and down


3:which is better for physic: "game studio wed block" or mdl (is there any good config for physic?)

thank you.

c4 robot does not use the physics engine, it's a couple of c_move with self calculated physics.

ok
but is there any answer to my questions with physic?

What!?
that Citroen C4 Game is made with 3dgs????

if you want to do fast cars, you have to use raycast vehicles. instead of tires made of physics objects, use rays and do your own calculations. the vehicle itself can still be a physics object.

"raycast vehicles" ?
can you explain more?
