How Do I make it so that touch fires when I jump constantly( read description)?

So if you didn't know touch event does not fire when you press on space bar constantly and keep on jumping is there any way I can make touch fire even when they are jumping because people can cheat and jump multiple times.

local Part = script.Parent
local debounce = false 


Part.Touched:Connect(function(touch)
	Hum = touch.Parent:FindFirstChild('Humanoid')
	if debounce == true then return end
if debounce == false then
	Hum:TakeDamage(10)
	debounce = true
	wait(1)
	debounce = false
end 
	
end)

Well the way I see it, you would like to damage player's when they are jumping, so you could do this two ways, one with a Remote Event which waits for the player to hit a SpaceBar and then damages them on the Server (this is because if they are damaged on the Client it will not replicated)

For this example, you will require a Local Script and a Server Script. The Local Script utilizes the UserInputService to determine what key the player presses

Server Script

local Remote = Instance.new("RemoteEvent")
Remote.Name = "PunishJump"
Remote.Parent = game:GetService("ReplicatedStorage")

Remote.OnServerEvent:Connect(function(player)
	player.Character:WaitForChild("Humanoid"):TakeDamage(10)
end)

Local Script

local Remote = game:GetService("ReplicatedStorage"):WaitForChild("PunishJump")

game:GetService("UserInputService").InputBegan:Connect(function(input, event)
	if input.KeyCode == Enum.KeyCode.Space then
		Remote:FireServer()
	end
end)

You can also damage them on the Server by simply checking if they begin to jump with the HumanoidStateType "Jumping"

Server Script

game:GetService("Players").PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		character:WaitForChild("Humanoid").StateChanged:Connect(function(old, new)
			if new == Enum.HumanoidStateType.Jumping or character:WaitForChild("Humanoid").Jumping == true then
				character:WaitForChild("Humanoid"):TakeDamage(10)
			end	
		end)
	end)
end)

However, this has the drawback of only not firing when the player continuously jumps

Another option you can do is to simply disable the player's ability to jump by setting the SetStateEnabled for Jumping to be false:

LocalScript

game:GetService("Players").LocalPlayer.Character:WaitForChild("Humanoid"):SetStateEnabled(Enum.HumanoidStateType.Jumping, false)

My final suggestion is to set the CanCollide property of the "Part" (script.Parent) to false, which will make any player jumping on it fall through it, damaging them with the script you already have.

Otherwise: Revised Server Script

local Part = script.Parent
Part.CanCollide = false
local debounce = false 

Part.Touched:Connect(function(touch)
	local Hum = touch.Parent:FindFirstChild('Humanoid')
	if debounce == true then return end
	debounce = true
	
	if Hum ~= nil then
		Hum:TakeDamage(10)
		wait(1)
	end

	debounce = false
end)

Since you are using FindFirstChild() you're original script would break if the result of this function was nil
