This is great! I made it all the way to 8, but couldn't win :) I like the idea of having to examine wind streams to plot your way through the map. This is an awesome tech demo, would be keen to see something more polished & fleshed-out.

There is a trick in level 7. You have to do something counterintuitive.

Very nice.

Has anyone made fluid dynamics sailing game yet?

You would need only two controls, trim and rudder (direction instead rudder might be easier to comprehend). Wrong trim and point of sail could broache or even capsize the boat. Oh, and you could add not just the winds but the sea currents and waves also.

Now I'm salivating.

Earlier quoted context omitted.

Really cool stuff! Both technically and on the game design side > Does someone know more games then the two I mentioned in the README (Plasma Pong and Pixeljunk Shooter) with more or less realistic fluid dynamics? A friend of mine, Thomas ten Cate, tried but eventually shelved a project to make a fluid-dynamics based game tha he called Archimedes [0]. Before he moved on to other projects he blogged about it[1]. Does…

Well, only the games/projects count which I would add to the readme. And sorry, I have to say no here.

No worries, I just wasn't clear on whether you wanted to know of more projects and devlogs on the same topic in general, or about finished games.

I suspect 3D fluid dynamics gets a lot slower a lot more quickly

Awesome! I encourage you to add it to the science-based games list https://github.com/stared/science-based-games-list

Thanks stared. I forked the repository and will make a pull request. Also I have seen your quantum game project.

You don't need 3D fluid dynamics for 2d sailing game.

You would have 3 separate 2d layers for wind, sea currents and then wave layer. The waves don't have to follow the wind, but they they could have specular reflection from the land. It would make sailing in complex archipelago or narrow choke points more realistic.

Can you explain the expf_fast function?

Actually no. I found them by googling. You can find more tricks in my utils file.

I guess you can read an explanation on a similar problem here: https://en.wikipedia.org/wiki/Fast_inverse_square_root

That is exactly what I am asking. So far I haven't seen such a game. But I think it is easy doable with a few changes. I will remember it as a possible idea for a game entry next year.
