Fading Text Frame

This code will create a frame that can show text in the middle of the players screen. It will hold this text for 3 seconds and then fade it out. This is very similar to the code that blizzard uses for zone changing.

Snippet

MOD_TextFrame = CreateFrame("Frame");
MOD_TextFrame:ClearAllPoints();
MOD_TextFrame:SetHeight(300);
MOD_TextFrame:SetWidth(300);
MOD_TextFrame:SetScript("OnUpdate", MOD_TextFrame_OnUpdate);
MOD_TextFrame:Hide();
MOD_TextFrame.text = MOD_TextFrame:CreateFontString(nil, "BACKGROUND", "PVPInfoTextFont");
MOD_TextFrame.text:SetAllPoints();
MOD_TextFrame:SetPoint("CENTER", 0, 200);
MOD_TextFrameTime = 0;

function MOD_TextFrame_OnUpdate()
  if (MOD_TextFrameTime < GetTime() - 3) then
    local alpha = MOD_TextFrame:GetAlpha();
    if (alpha ~= 0) then MOD_TextFrame:SetAlpha(alpha - .05); end
    if (alpha == 0) then MOD_TextFrame:Hide(); end
  end
end

function MOD_TextMessage(message)
  MOD_TextFrame.text:SetText(message);
  MOD_TextFrame:SetAlpha(1);
  MOD_TextFrame:Show();
  MOD_TextFrameTime = GetTime();
end
