How can I stop someone from receiving an item from a giver if they already have that item?
This script gives a player an item from ServerStorage called StrikeBall. However, I can not prevent a player from receiving multiple StrikeBalls. This is my attempt:
local Giver = script.Parent
local Gear = game.ServerStorage.StrikeBall
local debounce = false
function onTouch(part)
local Player = part.Parent:findFirstChild("Humanoid")
if Player ~= nil then
if debounce == false then
local Location = game:GetService('Players'):GetPlayerFromCharacter(Player.Parent)
if Location.TeamColor == Giver.BrickColor then
if Location.Character:FindFirstChild("StrikeBall") then
print("StrikeBall found in inventory.")
elseif Location.Backpack:FindFirstChild("StrikeBall") then
print("StrikeBall found in backpack.")
else debounce = true
local New = Gear:clone()
New.Parent = Location.Backpack
wait (5)
debounce = false
end
end
end
end
Giver.Touched:connect(onTouch)

Please provide explanation with your answers. Simply posting code does not spread knowledge of integral scripting processes which helps people understand the logic and reasoning behind your answer.
I made a helper method to to check and see if the person who touched the giver has the tool or not
local Giver = script.Parent
local Gear = game.ServerStorage.StrikeBall
local debounce = false
local function FindTool(player, tool)
local Character = player.Character
local HoldingTool = Character:FindFirstChild(tool)
local BackpackTool = player.Backpack:FindFirstChild(tool)
if HoldingTool ~= nil or BackpackTool ~= nil then
return true
end
end
Giver.Touched:connect(function(part)
debounce = true
local Player = game.Players:GetPlayerFromCharacter(part.Parent)
if Player ~= nil and Player.TeamColor == Giver.BrickColor and debounce and Player:FindTool("StrickBall") ~= nil then
Gear:Clone().Parent = Player.Backpack
end
wait(5)
debounce = false
end)

I understand that, but I am at a loss for words when trying to explain this. DewnOracle 115 — 9y

Just put :FindFirstChild("StrikeBall") ~= nil then
You were really close!

A Lua if check will pass as long as the condition is not nil or false. In other words, if something exists, the check will pass DewnOracle 115 — 9y
