@ArtOfShred do you intercept this function COMPASS_FRAME:GetBossBarActive()? |
Edit: Just took a quick look and looks like I hook BOSS_BAR.RefreshBossHealthBar().
And the menu toggle function calls COMPASS_FRAME:SetBossBarActive(true/false) depending on the setting to turn the bar directly on and off - just in case the player toggles it while they are standing in range of a boss.
Searching for "compass" in UnitFrames.lua gets you the two relevant functions for handling.
