Cast channel not always working

Cast channel not always working

Haleth opened this issue 14 years ago · 6 comments

Certain channeled spells don't always trigger the cast bar to show. I've found that it seems to mostly happen with channeled spells that require a regular cast to activate, for example Crystal Storm (92265), Ground Pound (76590) and Flay (79922).

Well, that sounds like something which is going to be a huge hassle to debug :P. I'll read over the code and see if I can spot anything wrong.

I'm unable to re-create this with the flayers in stonecore on normal. They cast just fine and channel afterwards without any issue.

I also couldn't see anything in the current implementation that might prevent it from happening.

Strange. This is my implementation of castbar:

local Castbar = CreateFrame("StatusBar", nil, self)
Castbar:SetStatusBarTexture("")

local Spark = Castbar:CreateTexture(nil, "OVERLAY")
Spark:SetTexture"Interface\\CastingBar\\UI-CastingBar-Spark"
Spark:SetBlendMode"ADD"
Spark:SetWidth(16)
Castbar.Spark = Spark

self.Castbar = Castbar

local PostCastStart = function(Castbar, unit, spell, spellrank)
    if Castbar.Text then Castbar.Text:SetText(spell) end

    if self.Iconbg then
        if Castbar.interrupt and unit=="target" then
            self.Iconbg:SetBackdropBorderColor(1, 0, 0)
        else
            self.Iconbg:SetBackdropBorderColor(0, 0, 0)
        end
    end
end

local PostCastStop = function(Castbar, unit)
    if Castbar.Text then Castbar.Text:SetText("") end
end

local PostCastStopUpdate = function(self, event, unit)
    if(unit ~= self.unit) then return end
    return PostCastStop(self.Castbar, unit)
end

self:RegisterEvent("UNIT_NAME_UPDATE", PostCastStopUpdate)
table.insert(self.__elements, PostCastStopUpdate)

Castbar.PostChannelStart = PostCastStart
Castbar.PostCastStart = PostCastStart

Castbar.PostCastStop = PostCastStop
Castbar.PostChannelStop = PostCastStop

There's nothing in that code which changes the update behavior of the castbar.

That's strange. I'm seeing it happen really often.

Done some more testing and it apparently only happens on the target frame. Here are two screenshots. The first shows the pre-cast of Crystal Storm on Slabhide with all 3 cast bars (nameplate, target, boss) appearing fine. The second shows the channel which appears only on the nameplate and boss frame.
