How do you add mobile support to this script?

[darrenthegamer129]

Hello, devs!
Does anyone know how I can add mobile support using starter GUI to this script?
There is also another problem where I cannot turn the valve if I press A, does anyone have an idea of what’s causing the problem?

Script in StarterGui

local player = game.Players.LocalPlayer or game.Players.PlayerAdded.Wait()
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local uis = game:GetService("UserInputService")
local holding = false
local e = 'nil'


repeat game:GetService("RunService").Stepped:Wait() until game.Players.LocalPlayer
local player = script.Parent.Parent
local mouse = player:GetMouse()
local selecting = false
local valve

mouse.Button1Up:Connect(function()
	if selecting == true then
		valve = mouse.Target
		if valve.Using.Value == false and valve.Parent == workspace.Valves and script.Parent.IsUsingValve.Value == false then
			if box then
				box:Destroy()
			end
			valve.Using.Value = true
			script.Parent.IsUsingValve.Value = true
			local camera = workspace.CurrentCamera
			local tweenservice = game:GetService('TweenService')
			local cf = camera.CFrame
			repeat
				wait(.01)
				camera.CameraType = Enum.CameraType.Scriptable
			until camera.CameraType == Enum.CameraType.Scriptable
			character.HumanoidRootPart.Anchored = true
			script.Parent.ValveUI.Enabled = true
			tweenservice:Create(camera,TweenInfo.new(1,Enum.EasingStyle.Cubic,Enum.EasingDirection.Out), {CFrame = valve.offset.WorldCFrame}):Play()
			repeat
				wait(.01)
			until valve.Orientation.X > 60
			wait(1.5)
			script.Parent.ValveUI.Enabled = false
			valve.Turn:Play()
			valve.Parent = workspace.Valves.Completed
			valve.Using.Value = false
			wait(0.3)
			tweenservice:Create(camera,TweenInfo.new(1,Enum.EasingStyle.Cubic,Enum.EasingDirection.Out), {CFrame = cf}):Play()
			valve = nil
			wait(1)
			script.Parent.IsUsingValve.Value = false
			character.HumanoidRootPart.Anchored = false
			repeat
				wait(.01)
				camera.CameraType = Enum.CameraType.Custom
			until camera.CameraType == Enum.CameraType.Custom

		end
	end
end)

mouse.KeyDown:Connect(function(key)
	if key == "d" then
		holding = true
		print('play')
		e = 'Front'
	end
end)

mouse.KeyUp:Connect(function(key)
	if key == "d" then
		holding = false
		e = 'nil'
		print('stop')

	elseif key == "a" then
		holding = false
		e = 'nil'
		print('stop')

	end
end)

while wait() do	

	for i,v in pairs(workspace.Valves.Completed:GetChildren()) do
		if i == 5 then
			workspace.Door.Open:FireServer()
		end
	end
	if valve and holding == true then
		if e == 'Front' then
			print('Q')
			valve.CFrame = valve.CFrame * CFrame.fromEulerAnglesXYZ(0.090,0,0)

		elseif e == 'Back' then
			print('E')
			valve.CFrame = valve.CFrame * CFrame.fromEulerAnglesXYZ(-0.050,0,0)


		end
	end

	if mouse.Target then
		if script.Parent.IsUsingValve.Value == false and mouse.Target.Name == '1' or mouse.Target.Name == '2' or mouse.Target.Name == '3' or mouse.Target.Name == '4' or mouse.Target.Name == '5' or mouse.Target.Name == '6' then
			if not mouse.Target:FindFirstChild('selection') and mouse.Target.Parent == workspace.Valves and mouse.Target.Using.Value == false and script.Parent.IsUsingValve.Value == false then
				box = script.Parent.ValveUI.selection:clone()
				box.Parent = mouse.Target

				selecting = true
				box.Adornee = mouse.Target
			end
		else
			selecting = false
			if box then
				box:Destroy()
			end
		end

	end	
end

Thanks for the help!

You can use ContextActionService, which is often used for mobile support controls. Settings binds for it should be fairly easy and you can even set priorities.

Could you possibly provide an example of how I can do this?
sorry if it may seem like a stupid question, but I’m horrible regarding scripting and other things.

Please do take a look at the link he provided. Roblox offers a full tutorial on ContextActionService

[DasKairo (Cairo)]

ContextActionService = game:GetService"ContextActionService" -- Service


ContextActionService:BindAction(    -- Binds an Action
    "ActionName",                   -- Name of the Bind so you can refer to it later
    function()                      -- The Function you want to fire when pressed
    end,
    true,                           -- Creates a Button for Touch Devices
    -- Below here you can add any KeyInput of InputType you like!
)

Just so you know, you may need to Move the Button’s Position around, Tho I do feel the Button like is a Bit Outdated, Here is Documentation however:

Thank you so much, will consider doing it.
