How to prevent players from picking up more than 1 tool?

I have a script that let's you pick a tool up from the replicated storage by holding e on a model. but you can get tons of that tool if you keep repeatedly pressing e, which can give you more than that 1 tool. i want to make it so you only can have 1 of that tool and can't get no more.

this is the script for the ProximityPrompt

local ReplicatedStorage = game:GetService ("ReplicatedStorage") local keyTool = ReplicatedStorage.Keycard

local KeyPart = script.Parent

KeyPart.ProximityPrompt.Triggered:Connect (function(player) local keyCopy = keyTool:Clone() keyCopy.Parent = player.Backpack

end)

please help!

heres my take on the script. Put this script (not local script) inside the KeyPart

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local KeyTool = ReplicatedStorage.Keycard

local KeyPart = script.Parent
local Prompt = KeyPart.ProximityPrompt

Prompt.Triggered:Connect(function(player)
	local bp = player.Backpack
	if bp:FindFirstChild("Keycard") or player.Character:FindFirstChild("Keycard") then -- checks if the player already has Keycard
		return -- does nothing if player already has Keycard
	else -- if player doesn't have keycard
		local KeyCopy = KeyTool:Clone()
		KeyCopy.Parent = bp
	end
end)

if you want the player to keep the keycard until they leave, do this:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local KeyTool = ReplicatedStorage.Keycard

local KeyPart = script.Parent
local Prompt = KeyPart.ProximityPrompt

Prompt.Triggered:Connect(function(player)
	local sg = player.StarterGear
	if sg:FindFirstChild("Keycard") then -- checks if the player's startergear contains Keycard
		return -- does nothing if player already has Keycard
	else -- if player doesn't have keycard
		local KeyCopy = KeyTool:Clone()
		KeyCopy.Parent = sg
	end
end)

i feel this is a lot simpler

yeah thanks anyways! the other guy helped me already. but if his doesn't work ever, i'll use yours

You should probably use his solution, it's much more simple and can work across multiple parts in case you have multiple prompts that involve giving out your keycard.

on second thought, i tested your solution and it works the same, and it's a lot simpler like you said, and this guy^^^ is right. thanks!

This may require some knowledge on dictionaries, but here is a script with some explanations.

local Part = script.Parent
local ProximityPrompt = Part.ProximityPrompt

--The Tool
local Tool = Part.Tool

--Use A Dictionary To Record Whoever Already Has the Tool
local playerWhoHasTools = {
	
}

--Create Event
ProximityPrompt.Triggered:Connect(function(player)
	--Check dictionary to see if player already has tool
	if not playerWhoHasTools[player.Name] then
		local toolClone = Tool:Clone()
		toolClone.Parent = player.Backpack
		--Record player in dictionary so they don't get the tool again.
		playerWhoHasTools[player.Name] = true
	end
	
	--Create Event So When Human Dies, They Are Removed from the Dictionary
	local humanPart = player.Character:FindFirstChildOfClass("Humanoid")
	if humanPart then
		local humanEvent
		humanEvent = humanPart.Died:Connect(function()
			--Remove from Dictionary
			playerWhoHasTools[player.Name] = nil
			--Disconnect Event
			humanEvent:Disconnect()
		end)
	end
end)
