How do i make it so when i click with an item, it rewards points?

I want to make a system where when you click with a bloxy cola in your inventory it gives you points. I can't seem to figure it out, help!!! Also I need to make it so when you have more points, your jump height and walkspeed increases. Also I dont know how to add game passes, and i want one that gives you points. THANK YOU!

To make the tool award points, you need to put a serverscript, a localscript and a remoteevent into the tool. Name the tool i.e. pointsRemote.

Then what we do next is set up the event handler for server event, aswell as a debounce to prevent them from spam clicking the tool.

After a successful click, we use PointsService:AwardPoints() to give the player one point.

Server script in the tool:

local remote = script.Parent.pointsRemote
local tool = script.Parent

local debounce = false
local interval = 1

remote.OnServerEvent:Connect(function(p)
	if debounce then return end
	debounce = true
	local plr = tool:FindFirstAncestorWhichIsA("Player") or game:GetService("Players"):GetPlayerFromCharacter(tool:FindFirstAncestorWhichIsA("Model"))
	if not plr then debounce = false return end
	if p ~= plr then --a lil security
		p:Kick("Stop firing someone else's remotes, nub exploiter")
		debounce = false
		return
	end
	game:GetService("PointsService"):AwardPoints(plr.UserId, 1)
	wait(1)
	debounce = false
end)

Localscript in the tool:

local remote = script.Parent.pointsRemote
local tool = script.Parent
tool.Activated:Connect(function()
	remote:FireServer()
end)

Now, to make their WalkSpeed increase, let's say by 1 for each 10 points, we're going to use PointsService:GetGamePointBalance() in any server script. It would be the best to have only one server script handle it.

local ps = game:GetService("PointsService")

game:GetService("Players").PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local hum = char:WaitForChild("Humanoid")
		hum.WalkSpeed = 16 + math.floor(ps:GetGamePointBalance(plr.UserId) / 10)
	end)
end)

local Tool = script.Parent

local Player = game.Players.LocalPlayer
local Character = Player.Character
local Mouse = Player:GetMouse()

Mouse.Button1Down:connect(function()
	while true do 
		Player.leaderstats.Points.Value = Player.leaderstats.Points.Value + 100
		Character.Humanoid.WalkSpeed = math.huge
		-- do rest
	end
end)
