RiggsBar is an emulation of the shield tracker that Riggnaros uses and can be seen in many of his videos since Dragon Soul. That I know of, Riggs has never released his user interface as a unit however I often see requests, wondering what his shield tracker is so I set out to create my own that worked like it.
Currently there are no slash commands but there is an in-game configuration through the escape > interface panel.
Individual shield toggles
Automatic group detection
2.0: Complete rewrite, converting to Ace Libraries
1.32: Moved a function, hopefully to solve the double numbers [0s] issue
1.31: All that stuff that I just said that I was going to do, well I actually did it this time! <3
1.3: Changed from Spell Names to Spell IDs which should solve issues with non-English clients also added a hide command and fixed < 1000 values showing up as .4k rather than 482
1.2: Added short numbers also believe to have fixed an issue where sometimes "0" would be shown behind the shield number
