Desperate help needed

[Dolbarian]

Ok, I have a problem...

Firstly, hi all!!

Ok, I am making a 3D game, It consists of a miniture globe with a road going
all the way around it, along with a user controlled car. I have added some
links to some images to show what i am making, of course, the world is not
finished yet, but i am looking to address my problem before i carry on with the
modelling.

As you can see, my scene in 3DS Max, and to test things so far, i have
imported the scene file into director, and everything is set up ok, however,
now i need to make the car stick to the road, so when the user presses the
control keys (accelerate for example) the car will drive along the road, i.e -
stick to it.

So far, i have added the controls and everything, but i cannot get the car to
stick to the road surface, the car just flies off in a straight line into the
distance.

I am really stuck on this one guys, i would really appreciate any help, i just
don't know what lingo to use. Someone told me about using a spring from the
ChromeLibs tools i think it was, but i can't get this to work properly :(

Can anyone help?

Have a look in the Havok Extra Lingo Ref. Guide. You'll find a mention of
gravity.

havok.gravity
Syntax havok.gravity
Access Get/Set
Description
This property holds the current force of gravity for the simulation. You
specify gravity
display units, so you need to be careful when setting it up. If using a scale
factor of
1.0 (i.e. meters) then gravity should be (0, -9.81, 0) to act appropriately
(assuming
positive Y is up).
Example
The following Lingo example displays the current gravity before changing it.
put havok.gravity
-- vector( 0, 0, -386.22 )
Havok Xtra Lingo Reference Guide
Copyright ? 2000/2001 Havok.com Inc. 3
havok.gravity = vector( 0, 0, -100 )
put havok.gravity
-- vector( 0, 0, -100.0 )

I dont know if itll be any use to you, but I believe it to be the answer you
are looking for.
