How do i make a script that takes away points when an item is bought?

Asked by

What i want to do is when the player has greater then or equal too (>=) points it subtracts points from the players in-game points. The thing was when the player didn't have enough money, it still subtracted it and gave them a negative number. Which i didn't want. And when i did less then or equal too (<=) when they had enough and they bought it and took away points it said they couldn't afford it when i didn't want it to.

This is my code:

(In a LocalScript)


local money = script.Parent.Parent.Parent.Parent.ShopMenu.PlayerPoints.num
local space1Avalible = script.Parent.Parent.PlanetSpotsAvalible.Ring_LVL1.Space1_Avalible
local space2Avalible = script.Parent.Parent.PlanetSpotsAvalible.Ring_LVL1.Space2_Avalible
local space3Avalible = script.Parent.Parent.PlanetSpotsAvalible.Ring_LVL1.Space3_Avalible
local space4Avalible = script.Parent.Parent.PlanetSpotsAvalible.Ring_LVL1.Space4_Avalible

local function addNewPlanetToList()
    local planetListItem = game.StarterGui.PlanetGui.ListOfPlanets.Planet1:Clone()
    planetListItem.Name = "Planet2"
    planetListItem.Text = "Planet2"
    planetListItem.Position = UDim2.new(0, 0, 0.35, 0)
end

local function getNewPlanet()
    local planet1 = workspace.PlanetPlacement
    local PlanetModel = Instance.new("Model")
    PlanetModel.Name = "Planet2"
    PlanetModel.Parent = workspace
    planet1.Parent = PlanetModel
    planet1.Position = workspace.PlanetPlacement2.Position
    addNewPlanetToList()
    print("Planet succesfully bought!")
end

script.Parent.MouseButton1Click:Connect(function()
    if money.Text >= "1500" then
        getNewPlanet()
        money.Text = money.Text - 1500
        script.Parent.Parent.Visible = false
        space2Avalible.Value = false
    end                                 --Right here!
end)

idk whats wrong..can someone plz tell me..?

You're trying to subtract a number from a string, but you can't do that. That's like saying print("Hello" - 10). I suggest creating a NumberValue, inserting it into your player, then subtracting from that value. However, here is how you would do it your way.

-- Use WaitForChild() on your children. I'm not even going to attempt writing that out. 
local money = script.Parent.Parent.Parent.Parent.ShopMenu.PlayerPoints.num
script.Parent.MouseButton1Click:Connect(function()
    -- Grabs all string numbers in the text, then turns them into numbers. 
    local my_number = tonumber(string.match(money.Text, "%d+"))
    if my_number and my_number > 1500 then
        getNewPlanet()
        money.Text = my_number - 1500
        script.Parent.Parent.Visible = false
        space2Avalible.Value = false 
    end
end)
