Debufftype timer

[darhanger]

For exmaple i have for certaine debuff by spell id or name. How i can make it for debuff type?

debufftimer = function(t, id, filter)
    local spellName;
    if tonumber(id) ~= nil then
        spellName = GetSpellInfo(id);
    else
        spellName = id
    end
    
    local expirationTime = select(7, UnitDebuff(t, spellName, filter))
    local duration = select(6, UnitDebuff(t, spellName, filter))
    if expirationTime ~= nil then
        return duration - (expirationTime - GetTime())  
    else
        return 0
    end
end;

Like

if debufftypetime("player", "Magic") > 3 then
--- do stuff
end

for example:

local PostUpdateDebuff = function(self, unit, button, index)
    local name, _, _, _, dtype, duration, expTime = UnitAura(unit, index, button.filter)
 
    if dtype == "Magic" and button.debuff then
        button.stealable:Show()
    end
end
