SteamID pointshop

[spocksgirl94]

I tried this code out for a model for someone's steam id:

ITEM.Name = 'Tyrael'
ITEM.Price = 10000
ITEM.Model = 'models/player/tyrael/tyrael.mdl'

function ITEM:OnEquip(ply, modifications)
	if not ply._OldModel then
		ply._OldModel = ply:GetModel()
	end
	
	timer.Simple(1, function() ply:SetModel(self.Model) end)
end

function ITEM:OnHolster(ply)
	if ply._OldModel then
		ply:SetModel(ply._OldModel)
	end
end

function GM:PlayerSetModel(ply)

	local mdl = GAMEMODE.playermodel or "models/player/tyrael/tyrael.mdl";
    if ply:SteamID() == "STEAM_0:1:1810974" then
        mdl = "models/player/tyrael/tyrael.mdl";
    end
    util.PrecacheModel(mdl)
    ply:SetModel(mdl)
end

And I got this error. (I know the name for the file is weird but thats just cause i wanted to test it really fast). Can anyone help me with this?

function ITEM:PlayerSetModel(ply)
[/LUA]

Oh right. Thanks rejax! But There is still a problem. Everyone can still see and buy the model it doesn't check the ID. Any ideas?

Just check the SteamID and return false for any other SteamID.

[spocksgirl94]

Just this?

if ply:SteamID() == "STEAM_0:1:1810974" then
        mdl = "models/player/tyrael/tyrael.mdl";
    end

I'm failing to see what you're trying to do
Is the model meant to be limited so that only a certain player can use it?
If so you should be using this function that's used by Pointshop

Of course replace the alive check with your steamid check
[quote]
Function: CanPlayerBuy
Arguments: ply (Player)
Realm: Server
Required: No
Description: Called when the player tries to buy the item. Return true or false.
Example:

function ITEM:CanPlayerBuy(ply)
return ply:Alive() -- only if alive
end

This still didn't work, unless I did it wrong lol

function ITEM:CanPlayerBuy(ply)
return ply:SteamID() == "STEAM_0:1:1810974" 
end
