Rolling dices on OpenMoko
Hi folks, a new application will be soon available for SHR (as soon as I understood how to build a package) : alea alea is a dice rolling application that you could use for role playing game. It's a very simple application which uses python-elementary -- no 3D at all, I would have love it but not enough time nor motivation --, here are some screenshots : Main page : you click on dices and score is automatically updated. If you need more dices, click on Add. There are 2 complete dice sets, but no more so buttons are big enough. http://imgur.com/8qxok.png This should limits the number of action to do in order to roll few dices. Second page (advanced) : a pad to enter a formula, like 5d6+5 Used formula are accessible through history, if you need to roll them several times during your game (but it's not saved on disk, you have to keep it running). http://imgur.com/Xth92.png This should be useful for big roll. Bug known : as formula becomes big, Roll button shrinks. I still don't understand totally elementary :/ Todo list : * allow to click on score to see details for each dice (some games requires to keep only certain dices) * add a '-' button hidden behind the '+' one (barely useful) * maybe a roll sound and a persistent history I will try to add it to SHR repository, but I don't understand what I need to do to achieve this. I hope you will like it, Xavier Cremaschi. PS : many thanks to podboy project, which is useful to discover how python-elementary and elementary work :) PPS : https://svn.troulite.fr/alea/ ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
