How can I add a hat when a player joins if a Boolean is true?

Asked by 5 days ago

I am trying to make a player equip a hat when they join if their hat purchased variable is true.

Part of my saving and loading script.

game.Players.PlayerAdded:Connect(function(player)
    local folder = Instance.new("Folder", player) --Creating variables
    folder.Name = "leaderstats"

    local folder2 = Instance.new("Folder", player)
    folder2.Name = "variables"

    local folder3 = Instance.new("Folder", player)
    folder3.Name="purchases"

    local val = Instance.new("IntValue",folder)
    val.Name = "Cash"
    local val2 = Instance.new("IntValue",folder2)
    val2.Name = "PPC"
    local val3 = Instance.new("IntValue",folder2)
    val3.Name = "CPS"
    local val4 = Instance.new("IntValue",folder2)
    val4.Name = "Price"
    local val5 = Instance.new("IntValue",folder2)
    val5.Name = "CPSPrice"
    local val6 = Instance.new("BoolValue",folder3)
    val6.Name = "TopHat"

    local stats = ds:GetAsync(player.UserId)

    if stats ~= nil then 
        val.Value = stats[1]--The numbers are the table below
        val2.Value = stats[2]
        val3.Value = stats[3]
        val4.Value = stats[4]
        val5.Value = stats[5]
        val6.Value = stats[6]
    else 
        val.Value = 0
        val2.Value = 1
        val3.Value = 0
        val4.Value = 10
        val5.Value = 500
        val6.Value = false
    end

This is what I tried in a separate script This prints No Hat

game.Players.PlayerAdded:Connect(function(player)
    local purchases = player:WaitForChild("purchases")
    local TopHat = purchases:WaitForChild("TopHat")
    if TopHat.Value == true  then
        local pmodel = player.Character 
        local hum = pmodel:WaitForChild("Humanoid")
        local ss = game:GetService("ServerStorage")
        local hat = ss:WaitForChild("TopHat"):Clone()
        hum:RemoveAccessories()
        hum:AddAccessory(hat)
        print("Has hat")
    else 
        print("Has No hat")
    end
end)

This is what I tried in the same script as the one that saves and loads It is in player added Doesn't print at all

    if player.purchases.TopHat.Value == true  then
        local pmodel = player.Character 
        local hum = pmodel:WaitForChild("Humanoid")
        local ss = game:GetService("ServerStorage")
        local hat = ss:WaitForChild("TopHat"):Clone()
        hum:RemoveAccessories()
        hum:AddAccessory(hat)
        print("Hat")
    else 
        print("No Hat")
    end

This is probably because there is no saving datastore. It uses GetAsync() on a datastore that either doesn't exist, or the datastore isn't saving in the first place. Try wrapping the GetAsync with a pcall too. It automatically sees that the datastore hasnt saved anything, so it gives you nil. This is why its saying no hat; the stats = nil. Hopefully this helps.

ds = game:GetService("DataStoreService"):GetDataStore(--put storename here-)
game.Players.PlayerAdded:Connect(function(player)
    local folder = Instance.new("Folder", player) --Creating variables
    folder.Name = "leaderstats"

    local folder2 = Instance.new("Folder", player)
    folder2.Name = "variables"

    local folder3 = Instance.new("Folder", player)
    folder3.Name="purchases"

    local val = Instance.new("IntValue",folder)
    val.Name = "Cash"
    local val2 = Instance.new("IntValue",folder2)
    val2.Name = "PPC"
    local val3 = Instance.new("IntValue",folder2)
    val3.Name = "CPS"
    local val4 = Instance.new("IntValue",folder2)
    val4.Name = "Price"
    local val5 = Instance.new("IntValue",folder2)
    val5.Name = "CPSPrice"
    local val6 = Instance.new("BoolValue",folder3)
    val6.Name = "TopHat"

    local stats

local success,errormessage = pcall(function()
    stats = ds:GetAsync(player.UserId)
end)

    if success then

if stats ~= nil then 
       print("Successfully retrieved stats")
 val.Value = stats[1]--The numbers are the table below
        val2.Value = stats[2]
        val3.Value = stats[3]
        val4.Value = stats[4]
        val5.Value = stats[5]
        val6.Value = stats[6]
    else 
        print("No current stats exist. Creating new ones")
    val.Value = 0
        val2.Value = 1
        val3.Value = 0
        val4.Value = 10
        val5.Value = 500
        val6.Value = false
    end
end


game.Players.PlayerRemoving:Connect(function(player)
    local stats = {} --put the references to the current leaderstats you want--
    local success,errormessage = pcall(function()
        ds:SetAsync(player.UserId,stats)
    end)
    if success then
        print("Saved Stats")
    end
end)
