AnimationGroup question

[myrroddin]

Confession: I have never dabbled with Blizzard's animation system. It confuses me greatly. Therefore, to the experts!

Is it possible to animate text created with CreateFontStrong, SetFont, SetText to shine or glint like bright metal does under the sun? How can this be accomplished?

If you're just moving a shine texture across the text, that's certainly doable. Manipulating colors and gradients would still need to be done on Lua side as the animation system isn't that fancy. It can only handle various movement, scaling, and fading.

Hmm, okay. So that means I would need a shine texture. Does one exist within WoW, or is that something that needs to be created?

This is my frame creation code. It is just the base, as I haven't populated it except for the title text. The good news is that the title text is the only part I want shiny or glittery. That would be line 31.

The plan eventually is to have have "MyrroUI" at the top in gold, version in silver below that, and at the bottom of the frame, "Installer" in bronze, all glittering, but baby steps.

-- if SVN checkout, replace version text --------
if version:match("@") then
    version = L["Developer"]
end
local addonName = "MyrroUI " .. version
 
function MyrroUI:CreateInstaller()
    -- create Installer window ----------------------
    local width = UIParent:GetWidth() / 2
    local height = UIParent:GetHeight() / 2
    local f = f or CreateFrame("Frame", "MyrroUIInstallerFrame")
    f:SetFrameStrata("MEDIUM")
    f:SetMovable(true)
    f:SetUserPlaced(false)
    f:SetClampedToScreen(true)
    f:SetSize(width, height)
    f:ClearAllPoints()
    f:SetPoint("CENTER", UIParent, "CENTER")
 
    -- frame backdrop ---------------------------
    f:SetBackdrop({
        bgFile = LSM:Fetch("background", "Blizzard Marble"),
        edgeFile = LSM:Fetch("border", "Blizzard Achievement Wood"),
        tile = false, tileSize = 0, edgeSize = 100,
        insets = {left = 0, right = 0, top = 0, bottom = 0}
    })
    
    -- colour it --------------------------------
    f:SetBackdropColor(1, 1, 1, 0.75)
    f:SetBackdropBorderColor(0, 0, 0, 0.75)
    
    -- "MyrroUI version" ------------------------
    local fo = f:CreateFontString()
    fo:SetFont(LSM:Fetch("font", "Roman"), 24, nil)
    -- fo:SetTextColor(255, 215, 0, 1)
    fo:SetPoint("BOTTOM", f, "TOP", 0, -26)
    fo:SetText(addonName)
    fo:SetTextColor(255, 215, 0, 1)
    
    return f
end

I'm sure there are a few shine textures in the default UI. Off the top of my head, combo points, action button cooldown frames, and the objective tracker uses them to name a few.
