Leaderboard script failing to increase a value while yielding no errors?
I've created a script that adds - or is supposed to add - a value to a players' gold count every five seconds. I've tried print debugging on certain parts, but I can't seem to find any errors. Where have I gone wrong?
Script, located in Workspace:
game.Players.PlayerAdded:connect(function(player)
leaderstats = Instance.new("IntValue")
leaderstats.Name = "leaderstats"
leaderstats.Value = 0
gold = Instance.new("IntValue", leaderstats)
gold.Name = "Gold"
gold.Value = 0
rank = Instance.new("StringValue", leaderstats)
rank.Name = "Rank"
rank.Value = player:GetRoleInGroup(3026186)
leaderstats.Parent = player
rank.Parent = leaderstats
end)
function getGold(P,rank)
Gold = P.leaderstats.Gold.Value
if rank == "[C] Peasant" then
Gold = Gold + 2
elseif rank == "[C] Merchant" then
Gold = Gold + 15
elseif rank == "[C] Shopkeeper" then
Gold = Gold + 20
elseif rank == "[C] Wealth Nobleman/Noblewoman" then
Gold = Gold + 50
elseif rank == "[M] Enlisted" then
Gold = Gold.Value + 5
elseif rank == "[M] Private" then
Gold = Gold + 10
elseif rank == "[M] Corporal" then
Gold = Gold + 20
elseif rank == "[M] First Sergeant" then
Gold = Gold + 20
elseif rank == "[M] Staff Officer" then
Gold = Gold + 200
elseif rank == "[M] 2nd Lieutenant" then
Gold = Gold + 30
elseif rank == "[M] 1st Lieutenant" then
Gold = Gold + 30
elseif rank == "[M] Captain" then
Gold = Gold + 35
elseif rank == "[M] Field Marshal" then
Gold = Gold + 35
elseif rank == "[M] High Constable" then
Gold = Gold + 40
elseif rank == "[N] Knight" then
Gold = Gold + 45
elseif rank == "[N] Baron/Baroness" then
Gold = Gold + 45
elseif rank == "[N] Count/Countess" then
Gold = Gold + 60
elseif rank == "[N] Duke/Duchess" then
Gold = Gold + 70
elseif rank == "[N] King" then
Gold = Gold + 100
else
print(rank)
end
end
while true do
wait(5)
P = game.Players:GetChildren()
for i, v in pairs(game.Players:GetChildren()) do
rank = v.leaderstats.Rank.Value
getGold(v,rank)
end
end

Your GetGold function doesn't modify P.leaderstats.Gold.Value -- it only modifies the Gold local variable.
In order to modify the IntValue, you have to somewhere explicitly set .Value somewhere:
-- always use local variables! local Gold = P.leaderstats.Gold -- i.e., NOT .Value up above -- we need to CHANGE .Value! Gold.Value = Gold.Value + 10
Instead of using elseif, you should consider using a dictionary:
local Earning = {
["[C] Peasant"] = 2,
["[C] Merchant"] = 15,
-- etc
["[N] King"] = 100,
}
.........
function getGold(P, rank)
local Gold = P.leaderstats.Gold
if Earning[rank] then
Gold.Value = Gold.Value + Earning[rank]
else
print("unknown rank `" .. rank .. "`")
end
end

Thank you, that definitely clears things up! Brinceous 85 — 7y

So was I creating a new local variable with the value of the initial Gold IntValue? And in your method you were stating the location of the variable, then declaring its new value? Brinceous 85 — 7y

That's exactly right. You made the variable Gold, set it to the old value, modified it, ... and then threw it away. The correct way says "this object holds a .Value, here's the new .Value for that object." BlueTaslem 18071 — 7y

Awesome, thank you so much for explaining that. I love learning things like this :) Brinceous 85 — 7y

After I've set up a dictionary, would it be appropriate to run an infinite loop (every 60 seconds) calling the getGold function as long as I have the P and rank variables defined before loop-calling the function? Brinceous 85 — 7y

Yea, that makes sense. BlueTaslem 18071 — 7y
