How do I make an animation only play once after touching an object?

I am making an obby sort of game and I have a lava jump like obstacle, and I have a script so that if you touch the object, a death animation plays. The issue is that sometimes the animation doesn't play, and sometimes, it plays the 1st few frames then repeats them. I think this is because I have it set the player's walkspeed to 0, and so the game thinks that the character is hitting the object over and over, therefore playing the animation over and over. I thought maybe I could make it so the player moves or gets pushed to another place, but, 1, their walkspeed is 0, and 2, I don't know how to do it. If anyone could help me then it would be very much appreciated! My code is below.

function onTouched(hit)
	local human = hit.Parent:findFirstChild("Humanoid")
	if human then
	human.WalkSpeed = 0
	local anim = human:LoadAnimation(script.Parent.Animation)
	anim:Play()
	wait(2)
	human.Health = 1
	wait(0.5)
	human.Health = 0
	end
end
script.Parent.Touched:connect(onTouched)

Thanks.

BlackOrange3343 told me to set a debounce and I looked up a roblox dev page on it and I tried something and it fixed it! Here is the code.

local anim = false
script.Parent.Touched:connect(function(hit)

	if not anim then
		
		anim = true
	if hit.Parent then
		human = hit.Parent:FindFirstChild("Humanoid")
		local anim = human:LoadAnimation(script.Parent.Animation)
	anim:Play()
	end
	wait(10)
	anim = false
	 
	end
		
end)	
	

Thank you BlackOrange3343.
