Has anyone actually made and submitted a racing sim with physics that at least include force, slip and friction?

I''m sorry I should have clarified my post, I meaant has anyone submitted a racing game _to this site_. It seems to me that the majority of people who like programming, or even computers, dont like racing games, they want to program a role playing game, or maybe just a platform game because they are trying to learn how to write games.

I only really like racing games I dont know why, maybe because I''m a revv-head at heart, and I''ve been coming up with ideas that involve cars NOT racing which hasnt really been looked at much in computer games, and I think it could be an audience for it.

At the moment I''ve been gathering physics information on race physics and it seems there''s a dozen different ways you can go about it. If anyone wants to get together and work on this I''d be happy to share my ideas.

though this is kinda off the original topic..

I imagine even the arcade "fun" games like Crazy Taxi have all these fundamental elements of racing physics..

you are absolutely right. different game, but definitely arcade..the San Franciso Rush driving model (which uses a 4 point driving model with unnaturally high values forced into it) was originally a police trainer back in the mid eighties. the police trainer was then massaged into Hard Drivin (also mid eighties) and then again into SF Rush. over the course of SF Rush new ideas were incorporated into the engine..for instance the arcade version of Rush 2049 took a new tire turning approach, which is used in real life, where the inside tire turns slightly more than the outside tire to enable better traction.

its amazing that such slight changes to "real physics" can give such an unreal experience.

Graham, I think I have read most of them... there may be one or two I havent, I''ll have a look.

I have read an article on the arcade game Hard Drivin'', it was a very nice machine for it''s time. I believe a bit of parallel processing was being done, with shared memory. I think I read it was about the equivelant of a Pentium 300 but dont quote me. I dont think I have played it on a console that had anywhere close to the physics that was used in the arcade version.

I agree, the slightest amount of more realism to the physics makes the gameplay a lot more fun. That is where a lot of commercial racing games went wrong I think. They had a deadline and they didnt put enough time into the controls and the physics. For eg Gran Turismo (sorry if I cant speel ) bored me to death almost. It didnt seem to have the depth of physics that even Need For Speed 1 had.

Need For Speed 1 was a classic IMO. The main drawbacks in it though were that the cars were confined to the track, with invisible barriers a few feet from either side of the track. I recently hacked it so that you could go offroad, and it made a MUCH more playable game, although I didnt go any further with it because each track had to be painstakingly edited. Also, the game engine only raised the car off the ground as high as the road at that particular point, so any offroad sections that were a different height to the road would had to have to been sectioned off so you couldnt drive on them, not too much of a loss really.

It is interesting to see when you go offroad in NFS and you hit trees they get flattened on the ground and make a slight thump noise. This was probably because the only objects that you could actually hit in the unhacked game were signs. Well it was fun anyway flattening 10 palm trees sideways. The only other bad point I could give NFS was that the rendering engine only rendered in the forward pointing direction... very nasty, but still fast even on a P100.

Which is why it surprises me that someone hasn''t made a racing game an ongoing project. Why cant independant programmers get together and work on a freeware Motor City stlye game? (I havent actually seen Motor City).

yeah we had a seriously optimized and in some places hacked-apart
driving model for the console versions of Rush. we couldnt add
the little bells and whistles the arcade guys were adding to the engine, cause we needed to run the model up to 4 times a frame (the drone cars ran through the model as well, just not every frame) on the n64''s 99mhz processor..

Ok but I dont have much at all. Just top view of a box for the car. I was trying to make at least friction and I got something like it. What have you got?
