Eluna script error：attempt to index global 'spell' (a nil value)

[Chen Jiang]

I wrote a logic to use Fire Ball (42833) to trigger the removal of Harvest Soul (28679) that Gothik the Harvester from Naxxramas casts on me.

When worldserver.exe is loaded, the command window prints an error: attempt to index global 'spell' (a nil value).

Although the code still works, but I hate to see errors. Any idea how to mitigate this error?

local function RemoveHarvestSoul(event, player)

    spell = player:GetCurrentSpell(1)

    if ((spell:GetEntry() == 42833) and player:HasAura(28679))

    then

        player:RemoveAura(28679)

    end

end

 

RegisterPlayerEvent(5, RemoveHarvestSoul)

can you post the whole startup error?

at first glance i would say you created a Global variable "spell" but then use it as a world object pointer "spell:GetEntry()"

Try this instead: 

local function RemoveHarvestSoul(event, player, spell, skipCheck)
    if ((spell:GetEntry() == 42833) and player:HasAura(28679))
    then
        player:RemoveAura(28679)
    end
end
 
RegisterPlayerEvent(5, RemoveHarvestSoul)
