I want to model a system, sort of like how Sim Tower started off life as an elevator systems model... a very basic 2D engine with some generic moving parts. I was looking at simulating a model of an airport, specifically the airstrip, terminals, parking and moving passengers from parking to the airplane through the concourse, based on different layouts and various constraints. Is there a general engine/platform I could look at for this sort of thing? Some things I've looked at so far and not been terribly impressed with were Love2d (Lua) libtcod (Python/C++/.net) Construct 2 RPG Maker Etc etc but these seem very pidgeonholed in to making a very specific type of game. I am a couple steps above a script kiddie but don't have the knowledge needed to build my own rendering engine etc. I feel like I might be better off re-purposing some sort of Checkers or Othello open source game and working from there.

Almost any programming language is acceptable for writing a simple 2d simulation program. Personally I'd just knock together a prototype in straight Java or Processing, as I am comfortable with both. What do you think a game engine or an existing codebase would do for you that you feel uncomfortable writing from scratch?

I took objective based C++ in high school (this was a year or two before Java at the HS/Uni level exploded) and 99% of our work was reading and writing to text files, arrays, bubble sorts, structs, hidden functions, etc.. very business based programming. Most of what I do for work is Bash scripting, SQL queries and some powershell. We very briefly touched on some goofy Carnagie Mellon University graphics library in high school, drawing squares that changed color in the last week of class. So I'm fairly nervous about getting my hands dirty writing some sort of slow, kludgy graphics when really I just want to write the logic under it. In theory some sort of game engine would let me bypass a lot of that. Also I guess I did a lot of Quake 1, 2 and TF2 level design at some point in the distant past.

For that kind of game I would look for two things in an engine: Tile-based maps, meaning a rather coarse grid-based map where things are nominally positioned at whole coordinates of, and freely moveable sprites, i.e. can be positioned at non-whole tile coordinates. The former because it's the easiest way to think about a map, the latter because you probably want smooth movements. Think of the elevators moving between floors in SimTower, nominally an elevator is always at one floor or another, but it will be shown as partway between two while transitioning. The actual simulation logic should only be bound loosely to the engine, and not depend too much on it. You still have to consider for yourself how you want to represent the maps (types and shapes of rooms, handling of walls and doors, and such) and the agents involved. If you haven't, watch some of the technical presentation videos about the new SimCity, where the developers talk about the Glassbox engine, it's pretty neat and you should be able to get some inspiration from it on how to handle this kind of simulation.

So...why is love2d inappropriate for that? It's not designed for "a specific kind of game" beyond assuming 2d graphics of some kind. Pygame or pyglet may also be worth a look.

I don't think there's any one book that covers everything you want, but there's a shortlist that will cover most of what you want. There are other books on all of these topics, so look around at the Amazon suggestions as well as what I point to.
As an aside, right now a question like this doesn't have a better home, but this really isn't the thread for it. Should we have a separate "small algorithmic/theory questions" thread?

Thanks ultrafilter that's definitely a decent list to get started. This is partly for me and partly for a CS class at the college I attend. Our textbooks for the class are Introduction to Algorithms and Algorithms (Dasgupta et al). The class is currently looking for suggested reading pertaining especially to optimization problems. This list helps! In regard to dynamic programming and integer programs (we just had a lecture on them today!), I'd love some resources.

I'm very slowly teaching myself to be better at command line stuff, and to do that I'm attempting to hamfistedly mash the prompt into something that I'd consider more user-friendly. This is what I've got so far: What I'm wondering is if there's a way to adjust the coloring of everything to the left of the directory and file listings? I've done a fair amount of googling but only find ways to adjust the rightmost column. I'm not even sure if I'm using the proper terms?

Not great as it runs on every request (which isn't bad actually I guess?). Javascript is asynchronous, if you need to do something sequentially the two options in javascript are either callbacks or promises. Depending on how you make your call to the DB you may have to wait for an event to fire before executing the callback.

Hey Goons, Does anyone know of a good software license for my needs? I'm creating a website that's been a ton of work... I didn't really want to open source it, but I needed something good for my resume, so I added the entire project to Github. Basically I don't mind if people look at my code, and learn from it or whatever if they can, but I don't want them selling it or actually putting it on their own website as-is (my whole website is literally open-source now). Is there a good license for this? How can I protect my work? Thanks!

If you don't want people to do anything with your code, why don't you just publish it and say 'all rights reserved' or whatever? Usually when people say 'open source' they mean that people are free to do more than just look at it.

A simple copyright might not add much as a deterrent. quote:Is there a good license for this? How can I protect my work? As mentioned, Standard copyright, i.e "all rights reserved" should cover you, and it is the default case for published things. Legally, adding 'all rights reserved' is really just making it clear IIRC. However, once you have published the code there is very little you can do if someone copies it or runs it without your permission. Personally I doubt you will lose many nights sleep over making your code actually open source.  Whether you like it or not, if your ideas are good other people will copy them, and perhaps the code too if they're exceptionally lazy. If your ideas aren't so good, you don't have to worry so much about other people using your code.

There is no default license of all GitHub projects. You retain all copyright. Sharing the source code for viewing is not equivalent to giving them a license to use it. You can put it under share-alike conditions, which say "if you want to use this, you must share any and all changes back to me". This would be something like the AGPLv3 or MPLv2.
