Fixing Wacom Tablets for Hearthstone in Windows

As of 2016-10-29, there is some sort of bug with Hearthstone where it will ignore clicks coming from a tablet. A quick search turns up complaints, but no solution:

  1. Wacom tablet pen support has been removed with patch 3.1.010357
  2. can't use mouse pen after update
  3. Wacom Tablet not working on Hearthstone

AutoHotKey for Windows has no such issues. And it can send mouse inputs that hearthstone can read… So, we'll make a new AutoHotKey script that clicks the left mouse button when the left mouse button is clicked. After installing AHK, make a new file with Notepad called wacom_echoer.ahk with the following contents:

;Map the left mouse button to the left mouse button. This makes Hearthstone, among other ;games, "see" it. #NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases. SendMode Input ; Recommended for new scripts due to its superior speed and reliability. SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory. return LButton::LButton
Edit: Fixed initial comments. Edit: It also fixes Cities: Skylines!

Double-click to run. Hearthstone should now work as expected.

I also followed these instructions to disable the click rings in Windows.
