How do I make local Variables within a function that's specific to a player?

So I'm making a door script where the player clicks on one side of a door and would appear on the other side and vice versa, there would also be a GUI transition animation for the player when they click the door and I plan on doing this using RemoteEvents.

local transitioning = false
script.Parent.DoorIn.ClickDetector.MouseClick:Connect(function(Plr)
	if transitioning == false then
		transitioning = true
		--fire said RemoteEvent
		wait(0.5)
		transitioning = false
	end
end)

This just makes it so that the player cannot fire an event whilst the transitioning is occurring, but this means other players cannot activate the transition whilst another player is already transitioning during that 0.5 wait period, I would like other players to click on the door and activate the event despite ANOTHER player is already transitioning.
