Bay 12 Games Forum

Hi guys,

I'm currently developing a new game based on space and one of its goals is some lightweight pressure/fluid/temperature simulation throughout the player spaceship. Like a good developer I'm cutting the project up into more palatable bite-size projects. The one I'd like to discuss and develop here is an open source version of DFs Cellular Automata simulation. After fairly extensive research I've concluded that the solution DF has implemented is actually really well done.
I'd love some help from the community here around a few specific points:
1. Has anyone already done the above? Eg is there already an open source implementation of DF's liquid and pressure simulation as discussed here? No point reinventing the wheel.
2. The above linked article discusses liquid simulation quite well. However I'm struggling to find information around how the system works with liquid interactions (water+magma), gases, temperature, etc. Would love some resources around this.

The plan here will be to develop a small open source project written in either C# or C++ (Undecided yet) and pluggable into Unity as its currently my engine of choice. But I'll try to keep it as engine agnostic as possible.

Hi,
Thought I'd give 40D13 a crack and I've run into a bit of a bug.
Load up a Dwarf Fortress game.
Hit d to designate something.
Click once in the game window, then move the mouse over a menu item in the designation menu. The mouse will automatically select the first item it touches.
Its like the left mouse button gets stuck down if you click in the game window and won't let go until you mouse over the menu.
This can be further exhibited by selecting 'Chop Trees' and using the mouse to select trees to chop down. You onyl need click once and just mouse over trees until your blue in the face.

Hi guys,

For a long time I've been a hobbyist game dev whose dabbled in almost all the roles a game needs to be complete (Modeller, Designer, Level Designer, etc) and I'm now taking a good look at programming. I've learnt my way around C++ over the last few months but the knowledge I am currently lacking is a higher level OO design process. That is to say, I'm curious as to how classes are organized and whether games like DF use the 'Model-Viewer-Control' methodology.

Ultimately I should probably pick up a book on the topic and read it cover to cover, but I'd love to have a discussion on how DF was designed from the ground up (Toady?) or how some of you would expect or go about designing and building a game like DF.
