When asking for help with an addon, you should include the name of the addon, and a link to its download page. You're fortunate that in this case I recognized my own addon in your screenshot.
Open Frames.lua in Notepad or another
plain-text editor. Go to the block starting at line 700:
Code:
if unit == "player" then
local SafeZone = Castbar:CreateTexture(nil, "BORDER")
SafeZone:SetTexture(config.statusbar)
SafeZone:SetVertexColor(1, 0.5, 0, 0.75)
Castbar.SafeZone = SafeZone
Castbar.Time = ns.CreateFontString(Castbar, 20, "RIGHT")
Castbar.Time:SetPoint("RIGHT", Castbar, "RIGHT", -4, 0)
elseif (uconfig.width or 1) > 0.75 then
Castbar.Text = ns.CreateFontString(Castbar, 16, "LEFT")
Castbar.Text:SetPoint("LEFT", Castbar, "LEFT", 4, 0)
end
Replace that block with this:
Code:
if unit == "player" then
local SafeZone = Castbar:CreateTexture(nil, "BORDER")
SafeZone:SetTexture(config.statusbar)
SafeZone:SetVertexColor(1, 0.5, 0, 0.75)
Castbar.SafeZone = SafeZone
Castbar.Time = ns.CreateFontString(Castbar, 20, "RIGHT")
Castbar.Time:SetPoint("RIGHT", Castbar, "RIGHT", -4, 0)
end
if unit == "player" or (uconfig.width or 1) > 0.75 then
Castbar.Text = ns.CreateFontString(Castbar, 16, "LEFT")
Castbar.Text:SetPoint("LEFT", Castbar, "LEFT", 4, 0)
end
The lines in green are the ones that changed. Save the file, then reload your UI (if WoW was already running).
However, you may want to think about whether you
really need this -- did you really forget which spell you
just started casting? Can you really not recognize the icon of your own spell?
