how do i make code that slowly does damage to a plyr, when they r in it?

Here is a script that slowly does damage while the player is in it. Unfortunately it doesn't work all the time. I put it in a block and put the blocks down different places so when the player walks through it it does damage.

  local damage = 1
	  local touched
	        local timebeforeotherdamage = 1
	 
	 
	 
	script.Parent.Touched:Connect(function(hit)
	    if hit.Parent:FindFirstChild("Humanoid") then
	        if touched == false then
	              touched = true
	        repeat
	     if touched == true then
	        hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health - damage
	 
	end
	wait(timebeforeotherdamage)
	        until
	        hit.Parent.Humanoid.Health == 0
	        end
	 
	    end
	    repeat
	    wait()
	    until
	    touched == false
	 
	 
	 
	 
	 
	end)
	script.Parent.TouchEnded:Connect(function(hit)
	    touched = false
	end) ~~~~~~~~~~~~~~~~~


sometimes it will do a little damage, but when you go out of the block and back in, it does A LOT. The code looks fine to me so I don't know whats wrong...

This might work! Put this in a script inside of your damage part. Change the wait(1) to change how many seconds you want to wait in between damaging. Change the hum:TakeDamage(50) to how much damage you want to do. If this doesn't work or gives an error, tell me in the comments of this answer and I'll fix my code.

local part = script.Parent
local debounce = false
part.Touched:Connect(function(touched)
	local hum = touched.Parent:FindFirstChild("Humanoid") --if its a player
	if hum then
		if debounce == false then
			hum:TakeDamage(50) --Damage you want to do
			wait(0.5) --wait whatever amount of seconds
			debounce = true
		end
	end
end)

**EDIT: you can make it the part's transparency 1 and cancollide false to make it sort of an invisible "damage zone"

Make sure it's a server script and inside of your part. Hope this works :)
