How do i loop an animation when "E" is pressed?

I'm trying to make a crawl animation play when you click "E" but i want it to loop until i release "E"... How?

Code:

local player = game.Players.LocalPlayer repeat wait() until player.Character.Humanoid local humanoid = player.Character.Humanoid local mouse = player:GetMouse()

local anim = Instance.new("Animation") anim.AnimationId = "http://www.roblox.com/asset/?id=1267282598"

mouse.KeyDown:connect(function(key) if key == "e" then local playAnim = humanoid:LoadAnimation(anim) playAnim:Play() end end)

The animation is 0.1 seconds long so do i just have to make it like 100 sec long and it will automatically loop until i no longer press it?

local player = game.Players.LocalPlayer repeat wait() until player.Character.Humanoid 
local humanoid = player.Character.Humanoid 
local mouse = player:GetMouse()

local anim = Instance.new("Animation") 
anim.AnimationId = "http://www.roblox.com/asset/?id=1267282598"


mouse.KeyDown:connect(function(key) 
	if key == "e" then
		while wait() do --loops animation
			local playAnim = humanoid:LoadAnimation(anim) 
			playAnim:Play() 
			mouse.KeyUp:connect(function() --function happens when key isn't pressed
				playAnim:Stop() 
		end)
	end 
end)

All I did was add a while loop in order to loop the animation. Inside the loop, I played the animation & put in a function that stops the animation. The function occurs when the key stops being pressed.

I think you could also put in while wait() and key == "e" do instead of the function, but I'm not sure.
