Odd wish: a digital dice roller for 4th ed

[Silverblade The Ench]

Hey guys, I thought that "random" algorithims were not very random? Always used to see annoying streaks with them?
(or maybe they were just bad formulas?)

Silverblade, try Random.org True randomness

Here goes:
Here's the code from a button that calls it:

        private void btnRoll_Click(object sender, EventArgs e)
        {
            Dice roller = new Dice(txtFormula.Text);
            lblResult.Text = roller.Roll().ToString();
        }

You should really toss some error handling in there... your class throws an exception for unexpected syntax.

Also, in general the built-in random functions are of pretty poor quality, regardless of language. I haven't done much research in the area, but the Mersenne Twister algorithm seems to be one of the best, and there's a version of it already made for all the popular languages (here's a C# implementation).

Such is the nature of things resident in my pile of incomplete projects. And exactly the reason I posted the code with caveat.

Geez.... I post a snippet of code that someone might be able to build off of -- or not -- and I get criticized because it's not full-featured? You're welcome.

That's amazing... I just sat to read this and I was going to post the same thing, only my algorithm comes from this article.

EDIT: Though after further review, the article needs some work. I'll take a look at Trevor Misfeldt's.

I would add a few other methods that allow for grouping dice rolls, for attack, damage, criticals, sheak attacks, secondary damage, etc.

I apologize if I offended you, it was not my intent. I was just trying to offer some advice.

I appreciate the post. It's a good helpful start to putting together a more fully featured program. Excellent.

No problem. Internet doesn't carry tone well. It's an evening's work from about six months ago. I mainly just wanted to see if I could get natural syntax for die rolling. I had intended on refining it and packaging it for reuse, but other priorities took over.

I posted it mainly because it was something I'd tried a couple of times before without luck. I figured it might be a useful boost to someone else in the same position.
