How do I make a script that gives me a tool when I click on a part?

I'm new to programming, I just need a key to be issued when I press a button.

Put the tool you want to be added inside replicated storage. Put a script inside the part. Also, put a click detector inside the part.

local part = script.Parent
local replicatedStorage = game:GetService("ReplicatedStorage")

part.MouseClick:Connect (function(player)
local tool = replicatedStorage.Tool:Clone() --Set this to the name of your tool.
tool.Parent = player.Backpack

I hope this helps.

My sincere apologies if this doesn't work.

Don't forget to accept this answer is this works!

Players = game:GetService("Players") -- Service Players (need to get player from character)

part = game.Workspace.Part -- Your part

ClickDetector = part.ClickDetector -- Add ClickDetector to your part

Tool = game.ReplicatedStorage.Tool -- Your tool in ReplicatedStorage

Put your tool to ReplicatedStorage and add ClickDetector to your part

ClickDetector.MouseClick:Connect(function(click)

	local character = click.Parent -- Character (we gets that for player that have backpack)

	local player = Players:GetPlayerFromCharacter(character) -- player itself

	local ClonedTool = Tool:Clone() -- You cloning your tool from RepStorage
	ClonedTool.Parent = player.Backpack -- And after you putting your tool to player's Backpack
end)

Say if you have any errors. And you should remember, put your tool to ReplicatedStorage.
