How to script mobile controls for plane??

Hi, I have made an airplane that flys. The controls I coded are only for keyboards. How can I get it to work with mobile players? Like with the joystick or make custom Gui buttons for them to control it.

Local script:

wait(1)

local inputS=game:getService("UserInputService")

local player=game.Players.LocalPlayer

local engine=script.Parent.Engine

local rotor1=script.Parent.Motor

local rotor2=script.Parent.Rotor



local gyro=Instance.new("BodyGyro",engine)

gyro.maxTorque=Vector3.new(1e4,1e4,1e4)

gyro.D=1250

gyro.cframe=engine.CFrame



local spd=Instance.new("BodyVelocity",engine)

spd.maxForce=Vector3.new(1e9,1e9,1e9)

local max_speed=50



local w,a,s,d,up,dn



inputS.InputBegan:connect(function(input)

	local code=input.KeyCode

	if code==Enum.KeyCode.W or code==Enum.KeyCode.Up then

		w=true

	elseif code==Enum.KeyCode.A or code==Enum.KeyCode.Left then

		a=true

	elseif code==Enum.KeyCode.S or code==Enum.KeyCode.Down then

		s=true

	elseif code==Enum.KeyCode.D or code==Enum.KeyCode.Right then

		d=true

	elseif code==Enum.KeyCode.E then

		up=true

	elseif input.KeyCode==Enum.KeyCode.Q then

		dn=true

	end

end)



inputS.InputEnded:connect(function(input)

	local code=input.KeyCode

	if code==Enum.KeyCode.W or code==Enum.KeyCode.Up then

		w=false

	elseif code==Enum.KeyCode.A or code==Enum.KeyCode.Left then

		a=false

	elseif code==Enum.KeyCode.S or code==Enum.KeyCode.Down then

		s=false

	elseif code==Enum.KeyCode.D or code==Enum.KeyCode.Right then

		d=false

	elseif code==Enum.KeyCode.E then

		up=false

	elseif input.KeyCode==Enum.KeyCode.Q then

		dn=false

	end

end)



function rotorSpd(spd)

	rotor1.TopParamA=-spd

	rotor1.TopParamB=spd

	rotor2.BottomParamA=-spd

	rotor2.BottomParamB=spd

end



local chg=Vector3.new(0,0,0)

local rot=0

local inc=0

while true do

	wait(.1)

	local lv=engine.CFrame.lookVector

	if up then

		rotorSpd(0.6)

		if chg.y<30 then

			chg=chg+Vector3.new(0,2,0)

		end

	elseif dn then

		rotorSpd(0.2)

		if chg.y>-30 then

			chg=chg+Vector3.new(0,-2,0)

		end

	elseif chg.magnitude>1 then

		rotorSpd(0.4)

		chg=chg*0.9

	else

		rotorSpd(0.4)

		chg=Vector3.new(0,1,0)--0,1,0

	end

	if w then

		if inc<max_speed then

			inc=inc+2

		end

		spd.velocity=chg+(engine.CFrame.lookVector+Vector3.new(0,0.3,0))*inc

		gyro.cframe=CFrame.new(engine.Position,engine.Position+Vector3.new(lv.x,-0.3,lv.z))

	elseif s then

		if inc >-max_speed then

			inc=inc-2

		end

		spd.velocity=chg+(engine.CFrame.lookVector-Vector3.new(0,0.3,0))*inc

		gyro.cframe=CFrame.new(engine.Position,engine.Position+Vector3.new(lv.x,0.3,lv.z))

	else

		inc=inc*0.9

		spd.velocity=chg+engine.CFrame.lookVector*inc+Vector3.new(0,0,0)

		gyro.cframe=CFrame.new(engine.Position,engine.Position+Vector3.new(lv.x,0,lv.z))

	end



	if a then

		if rot<math.pi/8 then

			rot=rot+math.pi/20

		end

		gyro.cframe=gyro.cframe*CFrame.Angles(0,math.pi/10,rot)

	elseif d then

		if rot>-math.pi/8 then

			rot=rot-math.pi/20

		end

		gyro.cframe=gyro.cframe*CFrame.Angles(0,-math.pi/10,rot)

	else

		rot=0

	end

end

Not too familiar with mobile controls, but if you make buttons, you should be able to do the same as with the letters and just detect when the button is being held or not.
