Inventory Item Keeps adding to backpack even after it is pressed. Someone please help me?
So I have a Murder-Mystery-Style Inventory system, and whenever I press an imageButton, let's say the Default Knife, It correctly gives me the item, but if I press it again and again, it'll keep giving me the item! I have tried to make 2 scripts to prevent this, but neither of them are working.. so can someone PLEASE review them and tell me what I'm doing wrong?
Script 1:
script.Parent.MouseButton1Click:Connect(function()
if game.Players.LocalPlayer.Backpack.DefKnife == true then
return
end
end)
Script 2:
script.Parent.MouseButton1Click:Connect(function()
if game.Players.LocalPlayer.Backpack.DefKnife = game.Players.LocalPlayer.Backpack.DefKnife then
return
end
end)
And In case someone is wondering, here is the script to give the item:
script.Parent.MouseButton1Click:Connect(function()
game.ReplicatedStorage.Tools.DefKnife:Clone().Parent = game.Players.LocalPlayer.Backpack
end)

One of the ways you can check if a folder such as the Backpack contains an object is by using :FindFirstChild()
Whenever you use FFC and the object is not found, it will return nil. Thus, if the statement used below returns nil, the tool will be given to the player.
local Player = game.Players.LocalPlayer
script.Parent.MouseButton1Click:Connect(function()
if Player.Backpack:FindFirstChild("DefKnife") == nil then
game.ReplicatedStorage.Tools.DefKnife:Clone().Parent = Player.Backpack
end
end)
You can also use the not keyword within an if statement to verify that the Backpack doesn't already contain the tool.
script.Parent.MouseButton1Click:Connect(function()
if not Player.Backpack:FindFirstChild("DefKnife") then
game.ReplicatedStorage.Tools.DefKnife:Clone().Parent = Player.Backpack
end
end)
