Traipse Beta 'OpenRPG' {100117-00} Traipse is a distribution of OpenRPG that is designed to be easy to setup and go. Traipse also makes it easy for developers to work on code without fear of sacrifice. 'Ornery-Orc' continues the trend of 'Grumpy' and adds fixes to the code. 'Ornery-Orc's main goal is to offer more advanced features and enhance the productivity of the user. Update Summary (Beta) New Features: Added Bookmarks Added 'boot' command to remote admin Added confirmation window for sent nodes Minor changes to allow for portability to an OpenSUSE linux OS Miniatures Layer pop up box allows users to turn off Mini labels, from FlexiRPG Zoom Mouse plugin added Images added to Plugin UI Switching to Element Tree Map efficiency, from FlexiRPG Added Status Bar to Update Manager New TrueDebug Class in orpg_log (See documentation for usage) Portable Mercurial Tip of the Day added, from Core and community New Reference Syntax added for custom PC sheets New Child Reference for gametree New Parent Reference for gametree New Gametree Recursion method, mapping, context sensitivity, and effeciency.. New Features node with bonus nodes and Node Referencing help added Dieroller structure from Core New DieRoller portability for odd Dice Added 7th Sea die roller; ie [7k3] = [7d10.takeHighest(3).open(10)] New 'Mythos' System die roller added Added new vs. die roller method for WoD; ie [3v3] = [3d10.vs(3)]. Included for Mythos roller also New Warhammer FRPG Die Roller (Special thanks to Puu-san for the support) New EZ_Tree Reference system. Push a button, Traipse the tree, get a reference (Beta!)
