WeakAura (custom?) trigger for "within the queued cast latency period"

[SlippyCheeze]

G'day. I have been trying to figure out how to get a WeakAura trigger to work for a while, and just can't manage it, which annoys me.

I would like to throw up an aura that fades in as I close on the latency of "next cast can be queued"; I fix that at 400ms, so I am fine with hard-coding it or just reading the CVar for the latency override rather than doing the complex "real cast latency" math.

What I can't figure out is how to have this happen for both instants (show when I am 400ms away from the GCD ending) and cast-time spells (show when I am 400ms away from the cast ending, even though the GCD finish three seconds earlier.)

As far as I can tell this does require a custom trigger, since I couldn't figure out how to use the status triggers to catch "x ms before the end of" on GCD or casting; otherwise I would have done a "require both" two trigger aura and just put both in place. So if you can tell me how to do that, I would be happy.

Only tested this a little bit but works fine so far. Use custom/event type.

Events: SPELL_UPDATE_COOLDOWN,UNIT_SPELLCAST_START,UNIT_SPELLCAST_STOP,UNIT_SPELLCAST_INTERRUPTED, UNIT_SPELLCAST_DELAYED

Custom Trigger:

function(event,...)
    local TOLERANCE=0.400
    --local TOLERANCE=GetCVar("maxSpellStartRecoveryoffset")/1000
    
    if event=="SPELL_UPDATE_COOLDOWN" then
    elseif event=="UNIT_SPELLCAST_START" or event=="UNIT_SPELLCAST_DELAYED" then
        if ...~="player" then return end
        local name,_,text,icon,startTime,expTime=UnitCastingInfo("player")
        WA_castexp=expTime and (expTime/1000-TOLERANCE) or 0
        WA_castdur=expTime and (WA_castexp-(startTime/1000)) or 0
    elseif event=="UNIT_SPELLCAST_STOP" or event=="UNIT_SPELLCAST_INTERRUPTED" then
        if ...~="player" then return end
        WA_castexp=0
        WA_castdur=0
    end
    local startTime,duration=GetSpellCooldown(61304)
    WA_gcdexp=startTime+duration-TOLERANCE
    WA_gcddur=duration-TOLERANCE
    WA_castexp=WA_castexp or 0
    WA_castdur=WA_castdur or 0
    local now=GetTime()
    return WA_gcdexp-now>0 or WA_castexp-now>0
end

Hide: Custom
Custom Untrigger:

function(event,...)
    if event=="SPELL_UPDATE_COOLDOWN" then
        return true
    elseif event=="UNIT_SPELLCAST_START" or event=="UNIT_SPELLCAST_DELAYED" then
        return ...=="player"
    elseif event=="UNIT_SPELLCAST_STOP" or event=="UNIT_SPELLCAST_INTERRUPTED" then
        return ...=="player"
    end
end

Duration Info:

function()
    if WA_gcdexp>WA_castexp then
        return WA_gcddur,WA_gcdexp
    else
        return WA_castdur,WA_castexp
    end
end

Thanks -- finally got time to test this out; it is almost what I want -- it triggers during the cast, rather than during the "safe to cast at the end" phase, but that is easy to adapt now that I have the pattern. Basically, I wanted it to trigger between 400ms and 0ms from the "end of cast or GCD", rather than before that, so that I have a visual "now is the right time to hit another button" hint. Easy fix though.

I really want the same trigger "between 400ms and 0ms from the end of cast or GCD". I tried now for nearly four hours to adapt the posted one and i still have no idea how to adapt it. SlippyCheeze can you please post how you adapted it? that would be great!

Sorry, I checked, and I don't have a backup copy of that around. Sorry. Turns out that this didn't work for me, so I ditched the idea most of a year ago.
