I’m trying to create a “flow” algorithm, like how water and magma flow in Dwarf Fortress.

I’m having a surprisingly(?) difficult time of it…

    Not really surprising… fluid dynamics [ http://en.wikipedia.org/wiki/Fluid_dynamics ] is *not* an easy field.
    Remember the movie Shrek? Apearantly the hardest ‘shots’ in the movie where Lord Farquaad fills a glass of milk and the whole ‘Shrek showers in mud’ scene.

      But if I simplify the problem enough, I should be able to create a simulation that is easy to implement yet still has some interesting features.

      At least, that’s what I keep telling myself…

      ¯\_(ツ)_/¯

        Well it’s certainly a fun subject that plenty of people have played around with (like the Box2d extension linked by the commenter below for example, I like that one). There is inspiration, ideas and code all over the web.

        It’s just that it’s such a textbook example of ‘thing that seems simple on the surface but is actually really complicated’ :-)

        Good luck anyway!

    you can take a look on how the guys from google did it over Box2d: https://google.github.io/liquidfun/

    Are you trying to make a physics fluid sim, or a tile based sim(water expanding into adjacent tiles)?
