Unity-Thrustmaster-T16KM-HOSAS-InputSystem

Automatically Differentiate Between Left- & Right Stick Inputs for HOSAS Use

Purpose

By default Unity does not recognize the difference between left- and right handed fight sticks. There is however a suitable system for XR-Controllers in the form of Configuration Usage Tags.

These scripts automatically assign a side to Thrustmaster T16000M sticks by reading the value of the little switch on the bottom.

Additionally the sides get updated automatically at runtime, should the switch be flipped again - or another device be plugged in.

Usage

Just place the scripts somewhere in your project.

Usage in Input Action UI

In the Input Actions Window, for each binding - the side can be chosen:

<HID::Thrustmaster T.16000M>{leftHand}/stick

<HID::Thrustmaster T.16000M>{rightHand}/hat

Usage in Code

Additionally the value of leftRightSwitchcan be read directly:

        // https://docs.unity3d.com/Packages/[email protected]/api/UnityEngine.InputSystem.InputAction.html
        InputAction changeHandAction = new InputAction(binding: "<HID::Thrustmaster T.16000M>/leftRightSwitch");
        changeHandAction.performed += (_ => foo()); // Right Side
        changeHandAction.canceled += (_ => bar());  // Left Side
        changeHandAction.Enable();

Though I see no reason to do so.

NOTE: To get notified of ANY change in stick side, use InputActionType.PassThrough.

Support for other Joysticks

For now this ONLY works for Thrustmaster T16000M joysticks. However, support for other sticks can be added:

Analogous to SidedTM16KM.cs:

1. Create an Input Layout Override
2. Add a binding using the SidedStickInitialize Attribute
3. Create a registerStick method
4. Add the method using the SidedStickRegistrate Attribute

If you do so, please create a pull request, so we can all benefit.
