<div class="IPBDescription">D:</div> I'm learning to code java, and I'm doing well, but there are a few things I've been wondering:
How do I create a random number, and after that, put paramaters on it(like 1-100, 1-10, all that).
I'll have more questions later, but this is the most pressing.

RandomIntGenerator( <lowestnumber> , <highestnumber> )
the numbers CAN be negative
{
//stuff between 0 and 10
}
I think, I'm still a Java nublet myself
IIRC, RPG Jssmfulhud answer wins.

Thats next year! This year is just wierd...stuff. Yeah. Hard to explain.
Thanks folks for this. I'm wanting to make my own little mini text RPG as a way of showing how even in basic programming, that unique game designs can come out(being all my friends are like "You must remake a classic like Pac Man or pong!")

Edit: And I *hate* the Java API. It doesn't show you anything, doesn't explain anything in terms that anyone can understand- its like a reference for people who've already memorized all of java's commands! <!--emo&:(--><img src='http://www.unknownworlds.com/forums/html/emoticons/sad-fix.gif' border='0' style='vertical-align:middle' alt='sad-fix.gif' /><!--endemo-->

True, finding out specifics about stuff requires that you have between a general and good idea of what you're looking for...but when you do, the API helps. For instance, it's very common to forget whether nextInt(6) will generate numbers from 0 to 6, 1 to 6, 0 to 5, 1 to 5....the api lets you know exactly.
Well, I actually want it to be rather simple. First I wanna dev my own battle system and a level up system. From there, I'll construct a first mini-story so that I can construct a stats based interaction system, similar to that in Deus Ex, or Bloodlines(being its text based, it should be merely a matter of creating the choice when a certain stat is reached).
I know it'll be lots of work, but it'll help me learn! <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin-fix.gif' border='0' style='vertical-align:middle' alt='biggrin-fix.gif' /><!--endemo-->

Qbasic is a terrible language for writing text RPG's though, the things get whipped off like no time in an object oriented language. The sequential line number hopping system of Qbasic is just not condusive to statistics storage or randomly generated events, and if you try to actually include a story, good luck because you are screwed.

Oh, it worked fine. It just went through several design iterations, took on mass, and eventually grew into a kind of single player MUD complete with a custom scripting language. A hell of a lot of fun to write, it just never got finished before I decided I'd better hurry up and move on to C.
See, my instructor is teaching us things according to a book, and when it comes down to it, he's barely 3 days ahead of us. Heh. But I was wondering, what command could make me go to whatever line I tell it to? A'la the "Goto" command(if I am thinking of it correctly).

Yeah, at that ending part. And yes, I realize that my current thing of this RPG is pretty basic- I'm still working on learning how to manipulate the JOptionPane stuff, as well as frame modifiers.
Also, being I haven't been able to use it yet until now, I can't seem to figure out how to get the random thing to work. Could someone show me it in a working context?
just make an operation (aka monsterDed) that gets called when monster.hp = 0
forinstance you could have an action that accepts a monster type object for its argument.
so you call monsterDed(*insert monster you are playing with atm here*) and it will pull out how much xp, what loot etc etc should be added to your character <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile-fix.gif' border='0' style='vertical-align:middle' alt='smile-fix.gif' /><!--endemo-->
and you can ofcourse create a class that handels all combat by simply passing it a playerChar object and a monster object.
hehe, I havn't messed around with Java in a whiel, but I still like it (I also definatly recomend that you get ussed to ussing the API as you will often find a simple way to do omething you have been doing the long way all along)
I had a project where I had to encode a number. We were suposed to use for loops, I found a piece in the API that let me simply set a deffenition for what each number should be changed into <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile-fix.gif' border='0' style='vertical-align:middle' alt='smile-fix.gif' /><!--endemo--> (oh, yah the grader told me not do do it b/c we were technicaly suposed to be doing for loops, so I left it in my code commented out <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif' /><!--endemo-->)

I don't know really any java, but I was under the impression that it handled this alot like C++... basicly there is no goto command, what you would do with goto loops in QB is done massively more efficiantly with loop commands, function calls, and multiple objects. If you need to back track your story in the game it should be built as multiple objects so that you can call them at any point in time from any point in the game. and levels and statistics should not under any circumstance be stored anywhere but in objects or callable functions.
[edit]oh, and Soulscorpion, I wasn't saying that Qbasic isn't capable of building text RPG's, I have a few partially finished ones in it myself. I was just saying that Qbasic is much messier and no where near as efficiant for building them as any of the object oriented languages are.
Actually, psychology is, like my own media sciences, a social, not a humanistic science. We're bound to empirical data, they're not <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif' /><!--endemo-->
But yeah, whenever people start talking about advanced technicals, part of my brain just shuts down.
