I'm having an issue with the new Energy Regeneration and my HUD (MetaHUD).
I just tried the live version on the Beta Realm, and even tho the Energy Regeneration on the Server changed, the HUD only updates my current energy like every 2 seconds.
As this Addon is more or less abandoned, I kindly ask you guys if you have any ideas how to change the .lua to make the Regen-Bar work like the default UI Bar, which now updates like every 0.1 sec from what I have seen.
Check the latest revisions of IceHUD for an example of how to handle this or check wowcompares.com for the PlayerFrame stuff that they're doing. Basically there's a new CVar called predictedPower that determines whether to use the old event-based regen mechanism or to update every frame. Unfortunately, the new change means that any addon wishing to display power regen must register an OnUpdate and suck up the CPU cycles to update themselves every frame. This is IceHUD's (and the default UI's) new method of doing things and it seems to work well. Good luck!
