Weak Aura string returning LUA errors

[Deleted]

Hi guys

So i just finished my wa string for warning me when my current spellcast drops me below a certain mana percentage, but after I completed it im often getting the warning about a lot of errors and the option to turn of my addons.

So I wanted to hear if there is anything in my lua code the issue or if anyone can pinpoint the root of my problems

function()
    
    local name, rank, icon, count  =   UnitDebuff("Player", "Arcane charge", nil, "PLAYER");
    
    local basecost = 3200;
    local cost = basecost * count;
    local spell = UnitCastingInfo("Player")
    local maxpower = UnitPowerMax("Player" , Mana);
    local mana = UnitMana("Player");
    
    local next = (mana-cost) / maxpower *100;
    local ap = UnitAura("player", "Arcane Power")
    
    
    if  next < 92 and spell == "Arcane Blast" and count >= 3 and ap~= "Arcane Power" then
        return true
        
    else
        return false
    end
    
    
    
end

Any chance you can share the error as well?

Either way.. easiest way to troubleshoot errors is by removing line to line and print the output of the variables you set, to see if they are alright.
You have to systematically check, this way you learn the caveats and nuances in coding.
Have fun..

Copying it in my editor: I think the variable next is a reserved function

function()
    
    local name, rank, icon, count  =   UnitDebuff("Player", "Arcane charge", nil, "PLAYER");
    
    local basecost = 3200;
    local cost = basecost * count;
    local spell = UnitCastingInfo("Player")
    local maxpower = UnitPowerMax("Player" , Mana);
    local mana = UnitMana("Player");
    
    local next = (mana-cost) / maxpower *100;
    local ap = UnitAura("player", "Arcane Power")
    
    
    if  next < 92 and spell == "Arcane Blast" and count >= 3 and ap~= "Arcane Power" then
        return true
        
    else
        return false
    end
    
    
    
end

Highlighted the problematic parts I see: If player does not have the debuff "Arcane Charge" your variable count will be nil, so no multiplication or numerical comparison is possible. Check for nil (if count then ...) to avoid.

Also, your call UnitPowerMax("Player" , Mana) should be UnitPowerMax("Player", SPELL_POWER_MANA).

There is indeed a lua function called next, but this does not prevent you to name any local (or global for that matter) variable the same.
