Hello,

I'm getting:

Quote

Server.lua:2001: calling 'HasSpell' on bad self (number expected, got nil)


On this function:
function PlayerLearnSpell(PlayerID, SpellID)
	if(PlayerID:HasSpell(SpellID) == true) then -- Line 2001
		return false;
	end
	
	PlayerID:LearnSpell(SpellID);
	return true;
end


What seems to be the problem?

The error says: You Not defined SpelliD

example: local SpellID = 999

note: im not sure whats youre trying to do but i think you're missing an " else "

SpellID is defined in the parameters of the function.

It doesn't need a else statement, if HasSpell returns true then the script stops it from reaching the LearnSpell by returning false.

I know what the error is, it's saying the spellid I'm using is a nil value, but I'm actually using: http://old.wowhead.com/spell=6673 (The WOTLK version)

Looks like the parameters are wrong. It's telling you that HasSpell takes a integer, but you tried to put nil (nothing) into it. Print all the parameters at the start of the function and find out what is going wrong. You might have them round the wrong way.

can you post more of the script, maybe, we can help you than.

where you call the function "PlayerLearnSpell" ? There you should search for the error.
Anyway, SpellID is nil and that is the problem. Where you set it in the Script? Maybe there is the root of the problem.
