I need this tool to be permanently be selected. I don't know how?

Here's my script:

---//SE-006 Script made by Cyotokatrov\\---
 -- kk let's begin.
while tool.Selected == false do --we want our victim to keep the tool lol.
	tool.Selected = true
end

x = game.Workspace
player = game.Players.LocalPlayer
tool = script.Parent

print("Loaded.")

tool.Selected:connect(function(m)
	m.KeyDown:connect(function(key)
		print("Key pressed: "..key)
	end)
end)

I made a while loop so the script would automatically check if the tool is unselected, although it doesn't work.

If you want to be sure that a tool can never be deselected, first disable the CanBeDropped property.

In a LocalScript, you will need to remove the backpack HUD so the tool can't be manually deselected by clicking on it or pressing a number.

game.StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Backpack,false)
