Need help with particle enable script

I have a script that should enable a particle emitter using the C key and should stop emitting when that key is released.

However, I’m not sure how to get that to work, and where the placement should be.

Here’s the script:

local userInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local particle = game.Workspace.FountainC.cannon.particleCore.fountain
local UpdateCon

userInputService.InputBegan:Connect(function(input, gp)
	if input.UserInputType ~= Enum.UserInputType.Keyboard then return end
	if input.KeyCode ~= Enum.KeyCode.C then return end

	if UpdateCon then
		UpdateCon:Disconnect()
		UpdateCon = nil
	end

	UpdateCon = RunService.Heartbeat:Connect(function(gp)
		particle.Enabled = true
	end)
end)

userInputService.InputEnded:Connect(function(input, gp)
	if input.UserInputType ~= Enum.UserInputType.Keyboard then return end
	if input.KeyCode ~= Enum.KeyCode.C then return end
	if not UpdateCon then return end

	UpdateCon:Disconnect()
	UpdateCon = nil
end)

This script is a LocalScript, and is located in the StarterGui.

Why connecting into a RunService?, I tested it and works fine like this:

local userInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local particle = game.Workspace.FountainC.cannon.particleCore.fountain
local UpdateCon

userInputService.InputBegan:Connect(function(input, gp)
	if input.UserInputType ~= Enum.UserInputType.Keyboard then return end
	if input.KeyCode ~= Enum.KeyCode.C then return end
	
	--[[
	if UpdateCon then
		UpdateCon:Disconnect()
		UpdateCon = nil
	end
	]]
	
	--UpdateCon = RunService.Heartbeat:Connect(function(gp)
		particle.Enabled = true
	--end)
end)

userInputService.InputEnded:Connect(function(input, gp)
	if input.UserInputType ~= Enum.UserInputType.Keyboard then return end
	if input.KeyCode ~= Enum.KeyCode.C then return end
	--if not UpdateCon then return end

	--UpdateCon:Disconnect()
	--UpdateCon = nil
	particle.Enabled = false
end)

Without the RunService connection values:

local userInputService = game:GetService("UserInputService")
local particle = game.Workspace.FountainC.fountain

userInputService.InputBegan:Connect(function(input, gp)
	if input.UserInputType ~= Enum.UserInputType.Keyboard then return end
	if input.KeyCode ~= Enum.KeyCode.C then return end
	particle.Enabled = true
end)

userInputService.InputEnded:Connect(function(input, gp)
	if input.UserInputType ~= Enum.UserInputType.Keyboard then return end
	if input.KeyCode ~= Enum.KeyCode.C then return end
	particle.Enabled = false
end)

local UserInputService = game:GetService("UserInputService");

local Held = false;

local Func = coroutine.create(function()
      if held == true then
      --Yourfunction
    end
end)

UserInputService.InputBegan:Connect(function(Input)
    if Input.UserInputType == Enum.KeyCode.C  then
        coroutine.resume(Func)
        Held = true;
    end
end)

UserInputService.InputEnded:Connect(function(Input)
    if Input.UserInputType == Enum.KeyCode.C then
        Held = false;
    end
end)

coroutine.resume(Func);Preformatted text
