Raid Buffs using Weak Auras

[Mirrikh]

As the title says, i'm trying to set up some weak auras to show that i have all my raid buffs, but i can't quite figure out how to get them to work since the buffs can change depending what you bring in the raid.

GetRaidBuffTrayAuraInfo() would probably be quite useful.

[Mirrikh]

not too good at lua, could you show me how the code should go?

If you could post whatever you have at the moment it'd help.

I don't use WeakAuras myself but I am aware of the principles behind it so these may or may not work. For each of the following set the trigger as an 'aura' or 'buff' (I'm not aware of WeakAura's terminology) on the player.

For a single aura that'll activate if you're not missing any raid buffs:

-- If you want it to activate if you're missing any buff types swap the 'true' and 'false'.
function()
    for i=1, NUM_LE_RAID_BUFF_TYPES do
        if not (GetRaidBuffTrayAuraInfo(i)) then
            return false
        end
    end
    return true
end

For an aura that activates if you're missing a specific raid buff type:

--[[
Each number corresponds to a specific raid buff type.
1 - Stats
2 - Stamina
3 - Attack Power
4 - Attack Speed
5 - Spell Power
6 - Spell Haste
7 - Critical Strike
8 - Mastery
]]--
 
function()
    -- Replace the '#' with a number from above for the matching buff type.
    -- If you want it to activate if you're missing the buff type swap the 'true' and 'false'.
    return (GetRaidBuffTrayAuraInfo(#)) and true or false
end

Thank you so much, this has been super helpful. What i had before was...i'm not even sure haha.

That will work, but won't take into account whether or not anyone in your raid can actually provide the buffs that are missing.

Here's a revised version that should ignore unavailable buffs:

-- If you want it to activate if you're missing any buff types swap the 'true' and 'false'.
function()
    local buffMask, maxBuffs = GetRaidBuffInfo()
    if buffMask then
        local numBuffs = 0
        for i = 1, NUM_LE_RAID_BUFF_TYPES do
            if GetRaidBuffTrayAuraInfo(i) then
                numBuffs = numBuffs + 1
            end
        end
        if numBuffs < maxBuffs then
            return false
        end
    end
    return true
end

thanks phanx, exactly how would i set this up? make a icon and give it a custom trigger with that code popped in?

That's a very good point.

Here's the single buff version:

--[[
Each number corresponds to a specific raid buff type.
1 - Stats
2 - Stamina
3 - Attack Power
4 - Attack Speed
5 - Spell Power
6 - Spell Haste
7 - Critical Strike
8 - Mastery
]]--
 
function()
    -- Replace the '#'s with a number from above for the matching buff type.
    if bit.band(GetRaidBuffInfo(), 2^(#-1)) > 0 then
        -- If you want it to activate if you're missing the buff type swap this 'true' and 'false'.
        return (GetRaidBuffTrayAuraInfo(#)) and true or false
    else
        return false
    end
end

Although, it seems GetRaidBuffInfo() only returns useful information when in a group. So if you're looking to use these revised ones when solo they won't trigger.

I've never actually used WeakAuras either, but I'd assume that's how it works.

Probably a long winded method of doing things, but I have a string for my own WeakAura raid buff tracker here:

http://www.tekagi.com/?page_id=56

It displays icons for the raid buffs you are missing, including food and flasks. It doesn't however, check if those buffs are available from your raid - but then I do find that knowing what my group is missing helpful too.

[Mirrikh]

thx alltherage, i wanted to do this after seeing your buff setup from your ui.
