I've made progress stubbing out a dice system on my local computer. Here's how it kinda works so far and/or I've planned it to work so far while I'm experimenting with it. In the Tabletop RP forum (naive implementation): - GM can add players to the roleplay's player whitelist. These are the only players that can post IC and create rolls. (i.e. RandomDude69 can't just start creating incessant rolls in random RPs) - GM can enable the "dice-enabled" flag on their roleplay which adds a "Rolls" tab. - For the Roll tab, I pretty much mimic [url]http://orokos.com/roll/?action=view_all[/url] which should be a familiar site to a lot of people in that forum. I started writing a dice expression parser (Example: "2d12+2r3"), but my friend pointed out that it'd be much nicer if I just made an actual widget/form. The widget would let you test your roll and it could spit out the dice expression for people familiar with dice-expressions to double-check their rolls. - People can link to their rolls from IC/OOC. <-- Seems lame to me but not sure how to improve it, yet. In other words, I can make it a bit less painful and a bit more integrated than Orokos. The above is just what I've come up with so far looking at how people are actually using a dice-rolling service. Not sure where to take it from there. Have no tabletop experience, so I've got no intuition for how it can get more integrated than that. I tried to think of ways to show rolls nicely inline with IC posts, but didn't come up with much.
