Addon to mark specific mob

[Grondath]

Hi,

I'm looking for some help on writing an addon that will put a raid target marker on a mob with a specific GUID if it is targeted by a raid member at any point. I'd like it so that if one mark is used it will use the next one on the next mob etc etc.

Do you think this would be easy enough to do? I would appreciate any help with it!

Thanks!

Are these all mobs with the same name? If so they would all be given the same UnitId.

The identifier is related to how the player is accessing the unit, not the other way around.

There's some info here: http://wowprogramming.com/docs/api_types#unitID

Yeah so I would need to check raid1target through to raid25target on a frequent basis...I'm guessing that would be quite laggy wouldn't it

Is there a way to tell when a raid member sets a mark on a mob? (I used to see a message in chat - "Player sets star on x" for example but don't anymore?)

Or alternatively a way to see which marks have already been used?

Got a working addon now, ty anyway! You can close/delete this thread if needed.

The setting for that is in the chat settings, I believe. As for the GUID thing, here's a proof of concept that should work reasonably well:

local updateInterval = 1
local guids = {
    ["0xF530007EAC083004"] = true
}
local IsInRaid, GetNumGroupMembers, UnitGUID, UnitExists, SetRaidTarget =
       IsInRaid, GetNumGroupMembers, UnitGUID, UnitExists, SetRaidTarget
local currentIndex = 1
local updateFrame = CreateFrame("Frame")
updateFrame:Hide()
updateFrame:SetScript("OnEvent",function(self)
    if IsInRaid() then
        if not self:IsShown() then
            self.elapsed = updateInterval
            self:Show()
    else
        self:Hide()
    end
end)
updateFrame:RegsiterEvent("GROUP_ROSTER_UPDATE")
updateFrame.elapsed = 0
updateFrame:SetScript("OnUpdate",function(self,elapsed)
    self.elapsed = self.elapsed+elapsed
    if self.elapsed >= updateInterval then
        while self.elapsed >= updateInterval do
            self.elapsed = self.elapsed-updateInterval
        end
        for i=1,GetNumGroupMembers() do
            local tarID = ("raid%dtarget"):format(i)
            if UnitExists(tarID) then
                local tarGUID = UnitGUID(tarID)
                if guids[tarGUID] then
                    guids[tarGUID] = false
                    SetRaidTarget(tarID,currentIndex)
                    currentIndex = (currentIndex%8)+1
                end
            end
        end
    end
end)

Should set the next raid target that hasn't been used by the addon yet (wrapping around after 8 (skull)) when the GUID is first encountered.
I'm not quite sure what you'd want to do with specific GUIDs though, as these are unique every time a mob is spawned. If you want NPC IDs, these can be extracted from the GUID (see this for details).

Thanks Treeston!

That's a lot better than my implementation

What do you think the effects of this might be on my frame rate?

It's up to 25 UnitGUID calls a second. It might lose you one or two FPS on lower-end machines, but should not have any noticable effect. If it does, consider increasing the update interval.

Just curious at what type of practical use this would have as it sounds interesting.

Like marking Lei Shi adds?
