How do I make my collision script for ladders mobile compatible?

Hello, I'm making a 2D game on Roblox. I have it so when you press W on the keyboard the collisions for the trusses are turned on, however, this only works on PCs or other keyboard enabled devices, can any one help me with this. Here is my code, I'm new to scripting so it'll probably look a bit messy.

local L = game.workspace.T1
local userInputService = game:GetService("UserInputService")
userInputService.InputBegan:connect(function(inputObject)
    if inputObject.KeyCode == Enum.KeyCode.W and L.CanCollide == false then 
            L.CanCollide = true
        end
    end)
userInputService.InputBegan:connect(function(inputObject)
     if inputObject.KeyCode == Enum.KeyCode.Space and L.CanCollide == true then
            L.CanCollide = false

    end
end)
userInputService.InputBegan:connect(function(inputObject)
     if inputObject.KeyCode == Enum.KeyCode.Space and inputObject.KeyCode == Enum.KeyCode.W  then
            L.CanCollide = true

    end
end)
