Summary0006969: Клиппинг майндфлай
Descriptionhttp://egammi.net/image/SnOy
ru.wowhead.com/spell=216513/
У нас не реализованно
Так же это действует и у лока на ru.wowhead.com/spell=198590
Steps To ReproduceВстаём у маникена, кастуем ru.wowhead.com/spell=216513/ , не прерывая каст, жмем МФ снова, длительность не изменится, от слова совсем
Additional InformationПруф скину в коммы, если надо .
Инфы по "клипанью" полно в Гугле


От тестера:

На данный момент клип механика не работает на эти ченнел спеллы,
их длительность никак не меняется

This was implemented in Cataclysm and is not specific to priest. Internally, this is called "positive pushback", and it happens by being an effective positive pushback (as pushbacks are usually negative). Here's how you **must** implement it, if you don't and cheat by making the new channel longer, addons will not calculate the ticks properly leading to ticks of damage happening out of sync with the addon's channel bar.

This is the code from Gnosis, a castbar addon:

function Gnosis:UpdateCastbar(cb, startTime, endTime, spell)
    local barname, cfg = cb.name, cb.conf;

    local fSPB = endTime - cb.endTime; -- spell pushback

    -- "positive" channel pushback (4.1)
    if(fSPB > 0 and cb.channel) then
        if(cfg.bExtChannels) then
            cb.duration = cb.duration + fSPB;
        end
        cb.endTime = endTime;

        if(cb.totalticks and cb.totalticks > 0) then
            for i = 1, cb.totalticks do
                cb.ticks[i] = cb.ticks[i] + fSPB;
            end

            if(cfg.bExtChannels) then
                if(cb.endTime - cb.ticks[cb.totalticks] > cb.channelticktime) then
                    cb.totalticks = cb.totalticks + 1;
                    cb.ticks[cb.totalticks] = cb.ticks[cb.totalticks-1] - cb.channelticktime;
                end
                
                self:DrawTicks(cb, cfg);
            end
        end
    -- "negative" pushback
    elseif(fSPB ~= 0) then
        cb.pushback = cb.pushback + fSPB;
        cb.endTime = endTime;

        self:DrawTicks(cb, cfg);
    end
end

This is a sniff of Cataclysm retail-era Mind Flay

Clipping was performed ingame at 0.8seconds remaining, with 0.1s of variance due to latency. The chat messages you see in the sniff are weakaura triggers that log the following Lua code: `select(6, UnitDebuff("target", 1))`

To implement this, you must:
- Send CHANNEL_UPDATE with duration 0 on recast (only when clipping)
- Send CHANNEL_UPDATE with extended duration after SPELL_GO
- **Never** remove the aura, just update its duration

And finally this is my implementation from a few years ago

Bad link, my link should have been https://github.com/The-Cataclysm-Preservation-Project/TrinityCore/pull/117/files#diff-3bc4fed9fddf12c9bf4b42c47f58a3c3f1637d3732ec503801881e151c3e4bf2R2867

Most of the remainder of that merge request is useless because it implements CATACLYSM DOT HASTE SCALING, which is NOT A THING IN LEGION. See issue 0027577
