I have two .lua file, one named sv_money.lua and the other economy.lua
The code in sv_money.lua is :
local meta = FindMetaTable("Player")
local PlayersMoney = {}
function meta:addMoney(amount)
if not amount then return false end
PlayersMoney[self:SteamID64()] = PlayersMoney[self:SteamID64()] + amount
end
And in economy.lua :
for k, v in pairs(player.GetAll()) do
v:addMoney(60)
Notify(v, "You've received 60€.", 5, "Generic" )
end
The expected result is the notification "You've received..." on players screen but the actual result is the error :
Lua Error: [ERROR] addons/economy/lua/autorun/economy.lua:63: attempt to call method 'addMoney' (a nil value)
1. unknown - addons/economy/lua/autorun/economy.lua:63
For an unknown reason to me this code in economy.lua works :
hook.Add("PlayerSpawnProp", "Cost", function(ply, class)
if not ply:canAfford(10) then
Notify(ply, "You don't have enough money !", 5, "Error" )
return false
else
Notify(ply, "You've spent 10€ to spawn this prop.", 5, "Generic" )
ply:addMoney(-10)
return true
end
end)
The problem was that economy.lua was executed client-side while my code was for server-side.
