  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.

  This is what taught me how to do handbrake turns.

  And shortly after I learned how expensive tyres were, I stopped doing handbrake turns.

    GTA didn't exist back then, so I had to learn them from the lore.

    And shortly afterwards, in addition to all the different physics-in-action experience, I learned about how car insurance excess works.

  Nostalgic!

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

  no dynamics model (uses bicycle model) but i built a solver for parking

    This is pretty fun!

  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.

  Thrust was by Jeremy C. Smith who went on to work on Exile with Peter Irvin

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

  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.

  I liked your idea. It was really cool.

  Really nice. GTA 1 & 2 were really amazing. I had a lot of good times with them.

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

  >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.

    Why needlessly do extra work when it's easier than ever before to modernize what is already made? Why would he want to be a vanguard for "hand coding"?

      Sometimes the reward lies in the doing, not in the done.

        And for that same reason people knit their own scarves but they don't expect the scarf they see at the store to be hand knit.

        And sometimes not.

        Seems the author chose option 2 and focused on the article instead.

        He's already done the doing.

          Yes, I recall well the famous words of Claude Monet: "Well, I painted one scene of water lilies. That should be more than enough for a lifetime."

    I've been a developer for not nearly as long as the author but long enough that at some point it felt like I was writing the same code and same abstractions over and over again and sometimes a new novel problem would reinvigorate my love of programming but today I'm happy to let an LLM write the tedious code while I give the more fun high level architectural direction and when reviewing the code sometimes I'll give it a nudge in a different direction. I suspect the author has written code like the 2d car physics many times over. Just my 2 cents.

  Feels like the original, just need some thing to run over.
• gaghak2010 26 minutes ago
  It's an interesting project, although not a physics expert I am so curious what the original version looked like!

  Just give us the prompt..

    I'd say you're fully off the mark here. That page contains serious architectural insight on how to make a "designed" car feeling work within a "physically correct" collision engine. Getting the balance right is super hard and he explains how to do it. I'm confident no AI could do that architecture, so this is most likely hours of hard work with a thin layer of LLM gloss on top.

    No, I don't want to see the prompt. Yes it has some llm tics, but it's clear that he went back and forth before arriving at this. Why would I be interested in the transcript?

      Pangram says the first half is human and second half is gen AI.

      Ran out of steam, I guess...

        yes and? someone sharing the details of an extremely popular project is super cool. comments like this will not encourage more people to share more cool things.

        I'd be ecstatic if more people used AI to share more cool things they've done. that'd be awesome. more of this blog post please.
