Free engines for cross-platform RTS games.

Are there any good engines for a sprite-based 2D real-time strategy games like C&C or Starcraft, preferably scriptable with Lua or Tcl or Python?

I looked at Stratagus and was unimpressed because it is confusing and inscrutable and has shitty documentation.  But maybe I'll have to reconsider if there are no other options.  Spring looks better from the developer's point of view, but it is 3D, and I can't 3D-model for shit.

I want a 2D engine because I can create physical models from inorganic garbage and glue (which is somewhat hard but yields good results, see Starcraft, Doom etc) and make 360° photos of them isolated on white background (which is easy if you have a photo camera and a rotating stand).

Why don't you take the time to document the stratagus code? Don't you know any system modelling tools that are intended for  the purpose of clearly presenting the different aspects of the system? Whenever I pick up an existing project, I always make high level system models of the system using tools such as data flow diagrams and entity relationship models (data analysis), flow process charts and control graphs (process analysis).

Stratagus became a piece of shit, when they rewrote it from Scheme to Lua. They should have rewritten it to Common Lisp. No cool AI vs AI battles for you.

U MENA should've kept it in Scheme.

Do you understand how long can it take to become familiar with a 400 KLOC C++ codebase?  Did you document other people's programs?

Make your own, >>1-san.

Are you making a Touhou RTS game? Because I really want one.

Writing game engines is unfun and tedious, especially the GUI part.

GUI part could b just a few lambdas linked to buttons, which itself are packed in a simple rect layout. Text input fields will be a little more difficult (you need to check user input for correctness), but nothing is impossible, when you use a good language.

Last time I checked, Racket had one problem with FFI - accessing memory through pointer was a little slow. But SDL and OpenGL worked nicely (i.e. games like Starcraft and World of Warcraft could be easily done).

That's why I do high level system models for the system and then do detailed models in the areas where I want to work. Models allow us to focus on certain aspects of the system so that we don't become blinded with information inside source code.

While I could make detailed models of these systems, I usually can't afford the time to work like that. For a system of that size (400kloc of a system using C++) I would budget no longer than one day to complete the high level system models. I budget one more day to do detailed models of the specific areas where I want to work. While I skip over many details in my models during this process, it's easy enough to update the models whenever I need it.

I do this work every time I pick up projects that don't have this sort of documentation. Going through this process means that I can quickly get a good overview of the system and get enough information to focus on my area. If I need to change my focus to other areas, it's simply a matter of filling in the details for my existing high level models.

Best one I've read in a while even on /prague/.

Thanks bro, I appreciate your show of support.

>>9 clearly never wrote any GUI outside of microsoft visual studio.
