I want to learn Clojure and the first idea for a "simple" app that popped into my head was some sort of roguelike (because I'm a gamer and this is what I like to do...) I could go on making hello world apps and tiny test apps that serve little purpose, but the way I learn is by setting an end goal and going for it. I don't intend on making this in the first shot, but like I said, there's the goal.
I've read quite a bit on Clojure, done some simple stuff like the "Hello World" apps and such already. I get the idea of the list structure (though I'm still VERY green on this.) A little background: I have an extensive background (10+ years professional, many more non-pro) in OOP and Procedural Programing using everything from Javascript/Actionscript to C# and even the gross VB4-6 in my early years and a little known Aspect Scripting (which I've totally forgotten by now.) I've only really dealt with threaded applications in C# because, let's face it... it's dead simple even using mutex locking. Non-professionally I started on an old TRS-80 then moved to a 80386 with GWBASIC/QBASIC and dabbled in C/C++ (but mainly I've just read tons of books on C/C++...) So, I'm trying to put all that aside and think Functional for this. I'm really trying, and it's mind bending to put all that aside... but I learn by example so here's where I ask some clues. I've downloaded Netbeans and an addon and played with it a little bit, but it seems to require a _main entry method and from the various tutorials around, I see that's not the norm. I'm having an interesting (to me) question around a using REPL. Once it's shut down, where does this code go? I feel like I'm in the old TRS-80 volatile coding days where you write some code, and if you shut down you've lost it all. Is this the case? So how do you save your code in a REPL? I understand these could be unique per editor so I understand if you get irate at me for asking such a silly question... I understand a list from ( to ) has the potential to be a function in separate threads because I poked my head into a tutorial I should have probably stayed clear of. If I create a function that I want to execute first on start up to check for a file and load it, but if it doesn't exist, create it and populate some array for world data. That's fairly straight forward, but in a game environment, this gets you nowhere but RAM full of data. About this point I'd then call a function create a player that would read in data from this world within a local proximity and act upon it. There's two ways I can see going about this. One is threading it off to act on it's own (which is what I'd love to do) and the other is appending it to the end of this creation function (have that function call the player on completion) but this is where I'm lost. Is it as simple as calling said method at the end of the list or is that filling up a stack of pain that I don't want to deal with when it all crashes? So I thought, I just need to do it. Just put it to silicon and start making something then I stared at the screen... A part of me would approach this as a client/server model which I'm not certain is right for functional programming. You have to have some communication method, or is the "world data" stored in a global location that is accessible to this player? Am I thinking about this all wrong? Would the player spawn the world load/creation only when it was needed? What if you wanted more than one actor? (would be a boring game if there were no enemies...) How does each actor access this world data? I realize some of this sounds totally noobish. Forgive me, but this is new territory for me. With OOP and functional languages I could scope a simple array of an array and reference it within it's scope. Is all Clojure scoped globally for data or am I supposed to go find something to handle that? I would figure with the nature of functional programming I could have it store data in a simple file format for the time being. That might not scale well, or it just may. I don't know. Sorry for the length of this post, the rambling, and the incoherent thought process. I realize I'm probably asking too many questions at once... :-\ -- You received this message because you are subscribed to the Google Groups "Clojure" group.
