Heyo. Here''s the deal I have to make car physics that are atleast equivalent to those of Crazy Taxi, and those are pretty good. The point that I''m stuck at right now is tires and suspension and how they affect the movement of the car. I''ve tried looking for resources around the net and can''t anything. I think my real problem is controlling how and where all my forces are and what they doing and how they moving everything. I know it''s a pretty broad questiong but all the common places don''t cover it at all (Physics of racing series, http://home01.wxs.nl/~monstrous/ <-this guys stuff). I''m just basically wondering if a) someone has a really awesome car simulator with source code or b) there are some places on the net that cover these subjects thouroughly enough.

you could probably give the car an attribute like wieght, and then just make it go slower depending on the wieght. You could say there were more attributes, but truthfully , to make it easier on yourself, you could just give it weight. look thrugh the AI forum, (artifical intelligence) and there may be some more advanced theories.

I dont know much about cars but relate to this example:

Person decides upon these attributes:

paint amount: 1 (so +5 weight)
added protection: 5(max)(+20 wieght)

if(wieght>=2222)

go slower

Well it''s a little more complicated than just weight, I will have that, but I have to calculate the weight on each tire using wight transfer which will cause the car to tip so much on each of them. hmm I may be on to something for that part of it. Sorry, just typing out my though process. But thanks for the help. You got me think of this.

than just make four wieghts.

int topleftweight, toprightweight, bottomleftweight, bottomrightweight;

and then assign + and - depending on certain attributes.

lol

I guess your trying to make it pretty advanced, the wieght idea wont work for you then. lol. What API are you using to make it? I may be able to find something for you, some source code.
