Need help with context action service

I tried making a toggle button for mobile users to sprint when you press it it does actually sprint but if you press it again nothing happens you stay sprinting I hope you understood
So how can I make it toggle?
Here is my code:

local ContextActionService = game:GetService("ContextActionService")
local char = game.Players.LocalPlayer.Character

local function Sprint()
	char.Humanoid.WalkSpeed = 26
end

ContextActionService:BindAction("Sprint", Sprint, true, Enum.KeyCode.LeftShift)

Try this.

local ContextActionService = game:GetService("ContextActionService")
local char = game.Players.LocalPlayer.Character
local toggle = 0

local function Sprint()
     if toggle == 0 then
	char.Humanoid.WalkSpeed = 26
        toggle = 1
    else 
	char.Humanoid.WalkSpeed = 16 -- default walk speed
        toggle = 0
     end
end

ContextActionService:BindAction("Sprint", Sprint, true, Enum.KeyCode.LeftShift)

Do I need to hold the button down?

#4

No, when the function Sprint() is called (once), it will change the walk speed to either run or walk, based on if the speed is currently 26 or 16.

#5

Well when I tried it,
It only works when I hold it down but you know what? I’m fine with it at least it works

Sorry I misunderstood, one moment please.

local UserInputService = game:GetService("UserInputService")
local char = game.Players.LocalPlayer.Character
local toggle = 0

UserInputService.InputBegan:Connect(function(input, isTyping)
	if not isTyping then
		if input.KeyCode == Enum.KeyCode.LeftShift then
			if toggle == 0 then
				char.Humanoid.WalkSpeed = 26
				toggle = 1
			else 
				char.Humanoid.WalkSpeed = 16 -- default walk speed
				toggle = 0
			end
		end
	end
end)

You can do this to toggle key on PC. You may have to utilize some other code on mobile, however I am not particularly good at mobile development.
