Why does the value change but the cost doesn't?

Asked by

If I just leave the value at 17 or in the script put cost.Value = Max.Value *2 or something like that it will work. But for some reason it will not work like this. The original cost is 17 and the value changes but the cost stays the same. Help please

Button script and cost script

local player = game.Players.LocalPlayer


script.Parent.MouseButton1Click:Connect(function()
    local upgrade = game.ReplicatedStorage.Functions.UpgradeBackpack:InvokeServer()
    if upgrade == false then
        script.Parent.Text = "You need more coins!"
        wait(1)
        script.Parent.Text = "Upgrade"
    elseif upgrade == true then
        script.Parent.Text = "Upgraded!"
        wait(1)
        script.Parent.Parent.Parent.Parent.Parent.Parent.Visible = false
        script.Parent.Text = "Upgrade"
        local cost = player.UpgradeCosts.BackpackUpgrade
       if player.backpack.WeightLevel1.Value == 2 then
                cost.Value = 20
                player.backpack.Max.Value = 80

upgrade script

UpgradeBackpack.OnServerInvoke = function(player)
    local cost = player.UpgradeCosts.BackpackUpgrade

    if cost.Value <= player.leaderstats["Coins"].Value then
            player.leaderstats["Coins"].Value = player.leaderstats["Coins"].Value -cost.Value 
            player.backpack.WeightLevel1.Value = player.backpack.WeightLevel1.Value + 1
            return true
    else
        return false
    end
end

How do I make the 'Upgrade Script' detect when the value is being updated ChefDevRBLX 90 — 5y

I don't understand what the question you're asking is, but if you want the 'Upgrade Script' to detect when the value is updated, you could use the 'Changed' event from the ROBLOX API. You can read about it here: https://developer.roblox.com/en-us/api-reference/event/Instance/Changed Loughdough 291 — 5y

Your question is a bit confusing,

I cleaned up your script a bit so you won't need those if-statements anymore by using a table for the backpackmaxweight outcomes. Use the ':Changed' event as Loughdough mentioned to do something when a property of an instance changes.

local player = game.Players.LocalPlayer
--You can get rid of all of those if-statements by using a table:
BackpackMaxWeights = {80,160,200,210,230,250,300,301,302,303,304,305,306,307,308,309,310,311}

--... (Other stuff with button and such)

player.backpack.Max.Value.Changed:Connect(function()
    local level = player.backpack.WeightLevel1.Value
    player.backpack.Max.Value = BackpackMaxWeights[level]
    player.backpack.NextUpgrade1.Value = BackpackMaxWeights[level + 1]
    if BackpackMaxWeights[level + 1] == nil then
        script.Parent.Text = "MAX!"
    end
end)

I hope you can maybe take inspiration from this script to possible solve your problem. I hope I have helped you.
