How do I make it to where if you press C a certain amount of times, it does something?

This is all I have right now, I got help from some websites n stuff. It makes you crouch, and that's it. You can stand back up, but that's all it does. I'm wanting it to be like: C pressed once = Crouch C pressed twice = Lay C press three times = Stand back up again

local key = "C"
local Player = game.Players.LocalPlayer
local Character = Player.Character
local AnimationID = "6974258690"
local CharAnimation
local ContextActionService = game:GetService("ContextActionService")
local FREEZE_ACTION = "freezeMovement"


local Sens = 0.12
local LastPressed = nil
game:GetService("UserInputService").InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.C then
		local Trig = false
		if LastPressed ~= nil then
			if tick() - LastPressed <= Sens then
				print("Open Menu")
				Trig = true
			end
		end
		if not Trig then
			LastPressed = tick()
		end
	end 
end)


game:GetService("UserInputService").InputBegan:Connect(function(inputObject, gameProcessedEvent)
	if inputObject.KeyCode == Enum.KeyCode[key] then
		animation()
	end
end)
function animation()
	if Character then
		local idleanimation = Character:FindFirstChild("AnimationCharacter")
		if CharAnimation then
			CharAnimation:Stop()
			ContextActionService:UnbindAction(FREEZE_ACTION)
		end
		if idleanimation then
			if idleanimation.AnimationId=="rbxassetid://"..AnimationID then
				idleanimation:Destroy()
				return
			end
			idleanimation:Destroy()
		end
		local Animation =Instance.new("Animation",Character)
		Animation.Name= "AnimationCharacter"
		Animation.AnimationId = "rbxassetid://"..AnimationID
		CharAnimation= Character.Humanoid:LoadAnimation(Animation)
		CharAnimation:Play()
		ContextActionService:BindAction(
			FREEZE_ACTION,
			function()
				return Enum.ContextActionResult.Sink
			end,
			false,
			unpack(Enum.PlayerActions:GetEnumItems())
		)
	end
end

It's kinda simple really.

Add a LocalScript somewhere (I put mine in StarterCharacterScripts) and put this code:

local uis = game:GetService("UserInputService")

local isCrouching = false -- check if the player is crouching
local isCrawling = false -- check if the player is crawling

local walkingAnimId = 1 -- change this to your walking animation ID
local crouchingAnimId = 1 -- change this to your crouching animation ID
local crawlingAnimId = 1 -- change this to your crawling animation ID

uis.InputBegan:Connect(function(key)
	if key.KeyCode == Enum.KeyCode.C then
		if isCrouching == false and isCrawling == false then
			isCrouching = true
			print("Player is now crouching")
			game.ReplicatedStorage.PlayMovementAnimation:FireServer(crouchingAnimId)
		elseif isCrouching == true then
			isCrouching = false
			isCrawling = true
			print("Player is now crawling")
			game.ReplicatedStorage.PlayMovementAnimation:FireServer(crawlingAnimId)
		elseif isCrawling == true then
			isCrawling = false
			print("Player is now walking")
			game.ReplicatedStorage.PlayMovementAnimation:FireServer(walkingAnimId)
		end
	end
end)

Then, add a RemoteEvent into ReplicatedStorage and call it "PlayMovementAnimation".

And finally, add a ServerScript into ServerScriptService and type this:

local rs = game:GetService("RunService")

local walkAnimId = 1 -- change this to your walking animation ID
local crouchAnimId = 1 -- change this to your crouching animation ID
local crawlAnimId = 1 -- change this to your crawling animation ID

game.ReplicatedStorage.PlayMovementAnimation.OnServerEvent:Connect(function(player, animationId)
	local animation = Instance.new("Animation")
	animation.Parent = player.Character
	animation.AnimationId = animationId

	local playAnimation = player.Character.Humanoid:LoadAnimation(animation)

	if animationId == walkAnimId then
		player.Character.Humanoid.WalkSpeed = 16 -- you can adjust this
	elseif animationId == crouchAnimId then
		player.Character.Humanoid.WalkSpeed = 7 -- you can adjust this
	elseif animationId == crawlAnimId then
		player.Character.Humanoid.WalkSpeed = 4 -- you can adjust this
	end

	while true do
		if player.Character.Humanoid.MoveDirection.Magnitude > 0 then
			playAnimation:Play()
		else
			playAnimation:Stop()
		end
		wait()
	end
end)

Hope this helps. :)
