Is a while loop the most efficient way?

[lelion77]

Hi so I have hundreds of parts and I want to change the color of the part (locally) that the mouse is over. Would it be best to do this in a while loop and check player:GetMouse().Target or is there a better alternative?

Someone told me while loops are unefficient, his argument was “You’re always one task.wait() away from game failure”.

The better way is to use an event

local mouse = player:GetMouse()

mouse.Move:Connect(function()
	if mouse.Target:IsA("Part") and mouse.Target ~= nil then
		-- Do whatever you want with the mouse.Target
	end
end)
