How Did They Do The Pixeljunk Shooter Liquid/Fluid Physics?

I bought Pixeljunk Shooter for PS3 and I really like how they’ve done the physics. Don’t know how it’s done, but that’s some cool liquid (or fluid) physics in action. You can shoot the water and it moves… you can “spray” lava and it turns into rock when hits water… it’s all so smooth and just super cool.

  1. Yeah, the water is thick, more like jelly or something…

  2. I was wondering the same when I was playing Pixjunk Shoot. the water some times seems a bit thick I’m not sure if any one else feels the same. But great game, another question that i wanted to know was how in Uncharted: Drake’s Fortune did the pull of the water in the game i know its off topic and not indie its just some thing to think of as well.

  3. A long-long time ago there was a game named H2O that contained puzzles involving water: http://www.bestoldgames.net/eng/old-games/h2o.php
    The physics was very simple (just particles that fall) but convincing (at that time :P). I think that if each particle becomes a metaball, you could get an interesting effect…

  4. @mirlix: I saw one screenshot of Dust – and was so impressed by that alone. Really looking forward to playing this one day.

  5. Yeah I really enjoyed playing this game. Now I’ve finally got my ps3 back from repairs; I’m playing it again to grab the achievements. :)

    Looking forward to Shooter 2

  6. Ironically, this came up when I was researching fluid physics for my project XD

  7. Rene Schulte released code that does pretty much the same tricks on fuild (minus the great game design):

  8. I’d say it’s similar to Phun:

    See the “liquify” feature at 0:55

  9. Quite impressive. Something similar is developed by Ubisoft in 3D at the moment. Im sure you will like this too. http://www.youtube.com/watch?v=CfKQCAxizrA
