How to make something take damage over time?

I have classified a few things in the script that might be helpful to figure out what the script entirely does. I haven't tested this so I don't know if it works or not. Hopefully this is what you were wanting help with and don't hesitate to tell me if it doesn't work or a question about it.

settings = { --This is a table, this table will store all the variables that you can change.
damageTime = 6, -- How many times It will damage the player
inbetweenTime = .5, -- The time you have to wait until It damages again
damage = 10, -- How much damage it will do
debounce = false, -- Not recommended to change this
}
game.Players.PlayerAdded:Connect(function(playerWait)
	playerWait.CharacterAdded:Connect(function(characterWait)
for i,v in pairs(game.Players:GetChildren()) do --[[ Grab all the players in the player service --]]
repeat wait() until workspace:FindFirstChild(v.Name)
workspace[v.Name].Touched:Connect(function(hit) --[[ This is a function which will fire when it is touched --]]
if hit.Parent:FindFirstChildOfClass('Humanoid') then --[[ This will check if it hits something w/ a humanoid --]]
if not settings.debounce then -- Checks if debounce is false
settings.debounce = true
for i = 1,settings.damageTime do -- This is a for loop that will loop a certain amount of times
hit.Parent:FindFirstChildOfClass('Humanoid'):TakeDamage(settings.damage) --[[ this will take damage--]]
wait(settings.inbetweenTime) -- this will wait for the time classified in settings.
end
settings.debounce = false
end
end
end)
end
end)
end)
