Flipping a default frame

How do I flip the WarlockPowerFrame? Specifically the Demonology power frame. Iíve tried /run WarlockPowerFrame:SetRotation() and /run WarlockPowerFrame:SetTexCoords() with appropriate values but neither work; I always get an error stating SetRotation() or SetTexCoords() are nil values.

Iím trying to flip the power frame upside-down.

With some free time I managed to flip it, but the shards remained unflipped.

This is what I used:

Code:
local Addon = CreateFrame("Frame")
    Addon:SetScript("OnEvent", function(self, event, ...) return self[event](self, ...) end)
    Addon:RegisterEvent("PLAYER_ENTERING_WORLD")

local function yOffset(Frame, Offset)
    local P = { Frame:GetPoint() }
    Frame:SetPoint(P[1], P[2], P[3], P[4], Offset)
end

-- Inverts texture vertically.
local function yInvertTexture(Texture)
    local Left, Top, _, Bottom, Right = Texture:GetTexCoord()
    Texture:SetTexCoord(Left, Right, Bottom, Top)
end

-- Inverts all child textures of a frame.
local function yInvertAllTextures(Frame)
    for _, Region in pairs({ Frame:GetRegions() }) do
        if Region:IsObjectType("Texture") then yInvertTexture(Region) end
    end
end

function Addon:PLAYER_ENTERING_WORLD()
    yOffset(WarlockPowerFrame, 180)
    yInvertAllTextures(WarlockPowerFrame)
end
Any help would be greatly appreciated.

One guess might be that the shards are populated after the player entering world event. You might want to RegisterUnitEvent unit_power, player, and flip the shards there. Since you only care about gaining/losing shards, I would include an if check at the beginning to see if the power type that is changing is shards.

The shards are added to the Shards table. Given the complexity of the shard template I'm not sure a crude "flip"will work for everything but...

Lua Code:
  1. -- Inverts all child textures of a frame.
  2. local function yInvertAllTextures(Frame)
  3.     for _, Region in pairs({ Frame:GetRegions() }) do
  4.         if Region:IsObjectType("Texture") then yInvertTexture(Region) end
  5.     end
  6.     for i=1, #Frame.Shards do
  7.         for _, Region in pairs({ Frame.Shards[i]:GetRegions() }) do
  8.             if Region:IsObjectType("Texture") then yInvertTexture(Region) end
  9.         end
  10.     end
  11. end
