Go Stand By the Stairs, So I Can Protect You

Posted by ryuzaki0 on from the phun-with-physics dept.

ewhac writes "It seems a programmer named Jetro Lauha, for his submission to the Assembly 2002 competition, decided to explore the realm of solid body physics simulations. So he wrote Porrasturvat -- 'Stair Dismount'. The game involves the application of force vectors to solid bodies connected by links with constrained range of motion, and observing their impact forces against other objects in the environment. ...Or, more colloquially, you push a guy down the stairs and see how much damage he takes. Apparently, any similarity between this game and the Terrible Secret of Space is entirely coincidental."

  1. The bug in this game... by Leon+da+Costa · · Score: 5, Informative

    You can get really high scores in this game by finding the "bug": I'll keep the hint minimal, but if you push hard on his foot, and try to push it down and back into the stairs, there's a chance he'll get stuck for a few seconds... resulting in very high scores.

      Heading is at or very close to 180.
      pitch between 80-85
      target: foot.
      full force

      I found best at 179.62 and 81.06 full force, got 40,000 before I left the first step

      Doesn't happen every time, and you can tell if you've got it by looking at his leg of the foot you hit. If its hasn't got atleast 10,000 before he gets off the first 2 steps, reset, try again. Vary the verticle angle, use the arrow keys, small increments.
      It needs to be full force, (or within 2 bars)

  2. good to see that a l33t haxor is already on top by grahamsz · · Score: 4, Informative

    sadly the database seems to have gone down - but look at http://db.cs.helsinki.fi/~jlauha/taat/porrasturvat /score/webscores.cgi tommorrow :)

      The game score was hacked pretty quickly after release of the game.. easiest way being to fiddle with the values straight to the memory when the game is running (trying to change the saved scores or online submit data should be a bit harder).

      If I get around taking time for the project, I'll be adding some more obfuscation for those things (as if that would help any ;-). Checking the hit on server side takes a LOT of cpu time but I guess some system for validating top entries could be viable.

  3. Uses the Open Dynamics Engine by Anonymous Coward · · Score: 5, Informative

    It uses the free (or to be specific LGPL) Open Dynamics Engine. A quite nice physics SDK, check it out if you are interested in physics engines.

    Lol :-)

    Anyway, the true story is that the idea for the game came when one work day I personally almost did a stair dismount, and we started joking with colleagues about making a game out of that..

    ...Pontifex. You try and build bridges which stay up when you run trains over them. Really cool.

    Woops, cocked that up! I blame Submit and Preview being right next to each other slighly more than my own crapness.
