How random is your random number generation? Do you seed your RNG from random.org or is it pseudorandom?
Seriously, it can't get any more random. We are using PhysX to throw the dice so it's really always random/different every time. Thomas
Since I am "just the artist" I have Ric (programmer) answer this. He doesn't have an account on this forum so I shall post his text here. He can explain things much better than I could and of course understand it much better than I do. Here we go: ----------------------- Hello everyone, I did the programming of this app, and Thomas asked me to explain in detail how it works. Most dice rollers figure out what number will come up and then make it look that way, but instead we: - Randomize the initial dice position - Randomize how hard each die is initially thrown - Randomize its direction and torque - When two dice collide, add a small random force besides the collision force pushing them away - You can flick your wrist to re-roll the dice, in essence becoming your own random "seed" - On top of that, when you flick your wrist to re-roll the dice we add a small random force to it, to further mix things up. There are many other small details, like the difference in friction between the walls and the floor. The end result is that on any throw of 3d6, there are over 300 random forces and torques calculated and applied before the dice come to a rest. So in essence what Dongs is saying is right - Newtonian physics are deterministic, much like what happens when you roll dice in your hand is deterministic, but it's almost impossible for someone to consistently roll 20s in a 1d20 by hand. What we do is emulate that natural process, and so many small things are randomized that the result is unpredictable unless you know the resulting forces at each step. Of course, in a small sample it's easy to be fooled by randomness, much like that guy everyone knows from the roleplaying group who consistently rolls 20s, or those days when one can't seem to roll to save his life. About your question, Hodapp, yes, it's pseudorandom. I considered getting a number of seeds from Random.org, but as you can see we would end up eating through the values so quickly, that using a SecureRandom implementation that complies with RFC 1750 provided us with pretty much the same result. If it's good enough for banking simulations, it's good enough for our dice roller Best, Ricardo
Anybody serious about dice roller can contact me via PM for a promo code. In return I expect a written review in the itunes store. Thanks for your interest Thomas
Pm sent, hopefully I can get a promo, this would be great for the (Very) numerous ocassions when my family and I want to play board games and somebody lost the die (or is it dices....I think it's dices, I should look that up)
Indeed, our dice roller is not only good for Dungeons&Dragons but for a variety of board games that include dice. Hope you like it. Thomas
I am Canadian, so your promo codes won't help me. Fortunately, I found your desktop version. It is beauty meets geeky. I would really like to endorse this dice roller, but I have a number of concerns. 1. The Dashboard widget has a full-screen button that attempts to take the widget full-screen but, in the end, only crashes the Dashboard. 2. There doesn't seem to be a way to choose which dice to re-roll. It will only allow me to re-roll all the dice. 3. There is no log of dice rolls. This is probably my favorite feature of the Dicenomicon. 4. I don't often need more than 10 dice, but I would rather not have that low ceiling. 5. It will not allow me to select d2 as an option. Both the Dicenomicon and Mach Dice allow for a coin toss. Just to clarify; I have only tried the mac version, and I am assuming that the iDevice app is a direct port (so correct me if I am wrong.) I think I will stick with the Dicenomicon for now: it has served me well. But I will keep an eye on your progress. Good luck.
Thanks for your input Starjimstar, Locking certain dice is something we are looking into for a future update along with other small ideas we have in mind. I and many others hardly ever need more than 10 dice at once for their game session. We will see what we can do about that in the future though. Adding a D2 shouldn't be that big of a deal and may make it into a future update as well. Development costs money however so we will have to see how RocknRoll does sale wise before we commit to any of the above. So in essence, without your support our hands are bound. Your input and support is greatly appreciated and we would love to take it one step further. Thomas
