This is far from a complete system but I dug it out for another post and thought it might be useful for anyone wanting to make a top down physics based driving game like those parking lot games you see on miniclip etc.



It could easily be altered to make more complicated vehicles like trucks with trailers etc. No media required for this version...

Hope you can find it useful!!

Not bad, although the skid button is a bit of a cheat. A brake button would be better I played about with a similar thing a bit ago but making the brake work properly and skidding when it should was a hard one to get working. I didn't use individual body and wheels though, just the direction the car was moving in, and the target direction it was aiming for.

Thanks baxslash. I was trying the same thing last month. It's good to see what someone else has done.

What if I just called it a brake button? It was just to see how easy it would be to reduce the lateral damping on demand really. It would be better to edit the lateral damping based on velocity, braking, surface type and probably a number of other factors for a finished engine.

Not really great coding but it might help someone with their own system. The lateral damping function is actually a bit of a hacked attempt, although it does seem to work fairly well.

I just hope it helps someone struggling with the concept.

Thanks for the code, Baxslash,
A few days ago I began with a parking game and the car's physics was driving me crazy.

Regards!

I could pickup a lot of useful tips on this if I could just stop playing it.

It's way to easy to have fun with the 'simple test' stuff.

While testing new bits in my WIP game, I set it up so that it was way too hard to get to the next level and laughed myself silly trying.

Yes, the temptation to "play" when we should be "working" is a hard one to avoid. It's also pretty hard to distinguish between the two sometimes when making games
