Roller Derby Manager (RDMGR) is an application for Roller Derby live-event production. It includes video capture, score overlays, team intros, skater and team profiles, full scoreboard, media controls, and much more. RDMGR is currently in use at the Arizona Derby Dames. (Also in development: an accompanying WordPress plugin.)
The Scoreboard allows leagues to run the bout under official Banked Track Roller Derby rules.
Teams have intros, and so with this in mind, the Slideshow feature was created. It’s nothing compared to PowerPoint, but it suffices for displaying team logos, skaters as they’re introduced, and full-screen sponsor slides.
There are several record types, including Skater, Team, Penalty, Phase (quarters for bouts), Videos, and Slideshows. Each record has its own form to add, edit, and delete. The Slideshow feature allows a user to add Skater, Team, and media files (images, videos), to a slideshow easily.
I built this feature in for fun: It reads a folder and displays image files that are added to that folder, allowing the user to perform minor edits, and then display those changes to the Capture Window. For example, I can connect my Canon Rebel DSLR to my computer, and send photos to a projector as I take them.
A Telestrator is a device used to draw/illustrate on top of a video screen, such as the yellow lines on most live sports. I built one combining Electron’s IPC, to send real-time coordinates from the user’s interface, to the Capture Window.
