  When mentioning foundational 2d driving models one simply can't omit Marco Monster (2003) [1].Also Physics for Game Developers (2001) had a hilarious chapter dedicated to car racing simulation. Most of the chapter is dedicated building the scene in a minute detail - for instance pointing out that the center of gravity of the car will change during the course due to fuel consumption - only to simplify and cancel out most things at the end to leave the reader with just a handful of variables.[1] https://www.asawicki.info/Mirror/Car%20Physics%20for%20Games...

  I'm sorry, I really want to like and understand this, but the diagrams are worthless and mostly incomprehensible.I would've liked to understand more about why it works the way it does, how it achieved the correct feel etc, not just regurgitate whatever the code does.I would've liked to know more about how the author achieved what they did, not a blog post anyone with an llm could've written.

  GTA I and II had really fun car physics. Just driving around and evading police was fun, in a way the later 3d games in the series didn't quite capture for me

  This is painfully awful Claudeslop. They didn't even bother changing the default style.

  It still feels great to play! I love the history too, it's actually a great example of why prototyping "toys" is so important in product development. It allows you to play with isolated concepts without baggage or the expectation to make things production grade. Just getting straight to the point.Great story, programming and mechanics.

  no dynamics model (uses bicycle model) but i built a solver for parkinghttp://truckslop.joshu.dev/

  Can you please add a "parking simulator" mode? Iam not joking, my SO wants a simple way to train parking and I think that could work very well. Or maybe just let one draw obstacles.

  This is what taught me how to do handbrake turns.And shortly after I learned how expensive tyres were, I stopped doing handbrake turns.

  To the creator, thank you. I spent many years almost 2 decades alter playing multiplayer gta2 with my good friend during late night sessions.Thank you for a great little physics engine

  Interesting that he namechecks Thrust from 1986, an absolutely amazing game for the BBC Model B, and I guess the first 'physics' game I ever encountered. The 'towing' physics were amazing.https://youtu.be/Dt44PEIWBRg?is=CbVTRyDfo8Nt56fHThrust was by Jeremy C. Smith who went on to work on Exile with Peter Irvin

  This feels incredible to play, even with the simple graphics. Wow. Top class

  Nostalgic!It'd be amazing to hook is up with the engine sound simulator: https://github.com/ange-yaghi/engine-sim

  no understeer? fronts are too grippy

  GFA Basic !… So many memories are coming back to me.

  If you accelerate the Car, then switch the configuration from Car to Brick, the brick won't slow down. Not sure whether is it intended but it feels wrong.

  StopTheMadness Pro users on iOS: exempt website, so you won’t keep selecting the text on the controls. May still highlight the “Speed Zoom on” line though.

  Even that little simulation is really fun. I’d like to play a little 2D game with this mechanic.

  d doesn't turn right for me, but shift+d does. Arrow keys do work though.

  Really nice. GTA 1 & 2 were really amazing. I had a lot of good times with them.
• hendry
  Feels like the original, just need some thing to run over.
• Cadman021
  I liked your idea. It was really cool.
• gaghak2010
  It's an interesting project, although not a physics expert I am so curious what the original version looked like!

  Really nice game

  > It began as a little wireframe demo written in GFA BASIC on my Atari ST home computer (and was later ported to C for use in the actual game).The Atari ST is in the news today on HN! (there was a TFA about the Atari Falcon, which was a really big Atari ST).

  >One weekend in late August 1996, I wrote a 2D physics simulation which later became the basis of the vehicle system in the eventually popular game "Grand Theft Auto" aka "GTA".I don't mean to be... judgemental, but if you had the talent to go something like this, why devolve on the remake? One could think that a person with your level of skill would be one of the main vanguard for hand coding. Again, I don't want to be too judgemental, as I am not a great programmer and use assisted tools when planning and designing personal apps, but I am just curious.
