Hello there, i have a minor problem, i don't know it's not working but i'm trying to do a framefade, with castbars, and it's not working. Any reasons?

local f = CreateFrame('Frame')
            f:RegisterEvent('PLAYER_TARGET_CHANGED')
            f:RegisterEvent('PLAYER_FOCUS_CHANGED')
            f:RegisterEvent("UNIT_SPELLCAST_SENT")
            f:RegisterEvent("UNIT_SPELLCAST_START")
            f:RegisterEvent("UNIT_SPELLCAST_CHANNEL_START")
            f:RegisterEvent("UNIT_SPELLCAST_CHANNEL_STOP")
            f:RegisterEvent("UNIT_SPELLCAST_STOP")
            f:RegisterEvent('UNIT_SPELLCAST_FAILED')
            f:RegisterEvent('UNIT_SPELLCAST_INTERRUPTED')
            f:RegisterEvent('UNIT_SPELLCAST_DELAYED')
            f:RegisterEvent('UNIT_SPELLCAST_CHANNEL_UPDATE')
            f:RegisterEvent('UNIT_SPELLCAST_CHANNEL_INTERRUPTED')
            f:SetScript('OnEvent', function(event)
                    if unit == "player" or unit == "target" or unit == "focus" or unit == "pet" then
                        if self.Castbar then
                            if event == "UNIT_SPELLCAST_START" or event == "UNIT_SPELLCAST_CHANNEL_START" then
                                UIFrameFadeIn(self.Castbar, 0.8, self.Castbar:GetAlpha(), 1)
                            elseif event == "UNIT_SPELLCAST_STOP" or event == "UNIT_SPELLCAST_SENT" or event == "UNIT_SPELLCAST_FAILED" then
                                UIFrameFadeOut(self.Castbar, 0.8, self.Castbar:GetAlpha(), 0.2)
                            end
                        end
                    end 
                end
            end)
        end
    end

Your OnEvent function doesn't have "self" or "unit" arguments. Change line 14 to this and it should work:

f:SetScript('OnEvent', function(self, event, unit)

Hmm, nop didn't work

local f = CreateFrame('Frame')
    f:RegisterEvent("UNIT_SPELLCAST_SENT")
    f:RegisterEvent("UNIT_SPELLCAST_START")
    f:RegisterEvent("UNIT_SPELLCAST_CHANNEL_START")
    f:RegisterEvent("UNIT_SPELLCAST_CHANNEL_STOP")
    f:RegisterEvent("UNIT_SPELLCAST_STOP")
    f:RegisterEvent('UNIT_SPELLCAST_FAILED')
    f:RegisterEvent('UNIT_SPELLCAST_INTERRUPTED')
    f:RegisterEvent('UNIT_SPELLCAST_DELAYED')
    f:RegisterEvent('UNIT_SPELLCAST_CHANNEL_UPDATE')
    f:RegisterEvent('UNIT_SPELLCAST_CHANNEL_INTERRUPTED')
    f:SetScript('OnEvent', function(self, event, unit)
        if unit == "player" or unit == "target" or unit == "focus" or unit == "pet" then
            if self.Castbar then
                if event == "UNIT_SPELLCAST_START" or event == "UNIT_SPELLCAST_CHANNEL_START" then
                    UIFrameFadeIn(self.Castbar, 0.8, self.Castbar:GetAlpha(), 1)
                elseif event == "UNIT_SPELLCAST_STOP" or event == "UNIT_SPELLCAST_SENT" or event == "UNIT_SPELLCAST_FAILED" or event == "UNIT_SPELLCAST_INTERRUPTED" or event == "UNIT_SPELLCAST_CHANNEL_STOP" then
                    UIFrameFadeOut(self.Castbar, 0.8, self.Castbar:GetAlpha(), 0.2)
                end
            end 
        end
    end)

Once a fade is in motion, you have to stop it in order to start a new one, or the new one will simply be ignored.

Try adding this before each fadein/out:

if UIFrameIsFading(frame) then 
    UIFrameFadeRemoveFrame(frame)
end

i bet 'self.Castbar' isn't defined because self, in this case, points to the event frame you created (f).

i'd suggest, if using things like .PostCastStart does not work, that you define a table in your layout when you create each .Castbar element:

local castbars = {}
--...
-- in your style function:
self.Castbar = YourCastBarFrame
castbars[unit] = YourCastBarFrame

and then in your onevent function you can just check for castbars[unit] and operate on that.

.. or you could just change the 'self' argument in the OnEvent function to something else, Then the variable self will refer to variable you want
