-- Script
local TextButton=script.Parent
local gui=TextButton.Parent
local player=gui.Parent.Parent
local newtool=game.ServerStorage.Sword2
--local cost,debounce=20,nil;
TextButton.MouseButton1Click:Connect(function(...)
--if debounce or not player.leaderstats.Points.Value>=cost then return end
--debounce=true
local char=player.Character
local backpack=player:FindFirstChild"Backpack"
local tool=(backpack and backpack:FindFirstChild("Sword1")
or char and char:FindFirstChild("Sword1")
)
if tool then
--player.leaderstats.Points.Value-=cost
tool:Destroy()
newtool:Clone().Parent=backpack
end
--wait(.5)debounce=false
end)
Solution
We would need a LocalScript, Script and a Remote Event which would be used to communicate between the client and server.
LocalScript
local Client = game.Players.LocalPlayer
local PlayerGui = Client:WaitForChild("PlayerGui")
local Button = PlayerGui.ScreenGui.TextButton
local RemoteEvent = game.ReplicatedStorage.RemoteEvent
local function OnButtonClick()
RemoteEvent:FireServer()
end
Button.MouseButton1Click:Connect(OnButtonClick)
Script
local RemoteEvent = game.ReplicatedStorage.RemoteEvent
local Sword = game.ServerStorage.Sword
local function GiveSword(Player)
if Player.Backpack:FindFirstChid("Sword") then
Player.Backpack.Sword:Destroy()
Sword:Clone.Parent = Player.Backpack
else
Sword:Clone.Parent = Player.Backpack
end
end
RemoteEvent.OnServerEvent:Connect(GiveSword)
Extra info
If you want to hide something from the client put it in ServerStorage or ServerScriptService since they can't view what's inside, but the client won't have access to objects in these services. So, if you wanted to access something from inside of these services you can do it via remote event also make sure to validate the stuff coming through the remote event because an exploiter can fire it whenever they want.
