Description

Moves around some conditional guards so that we don't unnecessarily wrap entire classes. This stops downstream packages from having to also wrap Input System objects with similar conditionals.

Only device class definitions that get replaced by specific packages should be entirely wrapped.

This PR is a copy of the internal PR created here: https://github.cds.internal.unity3d.com/unity/com.unity.inputsystem/pull/5

Changes made

Removes #if UNITY_INPUT_SYSTEM_ENABLE_XR && (ENABLE_VR || UNITY_GAMECORE) && !PACKAGE_DOCS_GENERATION
guards from wrapping entire class files under InputSystem/Plugins/XR/Devices and InputSystem/Plugins/XR/Haptics.
This makes it so any packages that want to use these Input System package objects don't have to also wrap the use of those objects with #if ENABLE_VR guards. Classes that should ignore Package Generation have been added to the filter.yml file.

We now only wrap the use of device descriptors with #if UNITY_INPUT_SYSTEM_ENABLE_XR to prevent use when the XR Module package is not installed.

Testing status & QA

Engines Supported: 6.2, 6.1, 6.0, 2022.3, 2021.3

Test 1:

  • Create project (or use an existing one)

  • Install Input System package

  • Install OpenXR package (this package uses the Input System but currently does not wrap any objects).

  • Switch platform from Standalone or Android into tvOS or QNX (ENABLE_VR conditional wont be defined on these platforms)

    Expected result: No compiler errors

Test 2:

  • Create project (or use an existing one)

  • Install Input System package.

  • Install the com.unity.xr.oculus, com.unity.xr.openvr, and com.unity.xr.windowsmr packages (these packages override certain device class definitions).

    Expected result: No compiler errors

Test 3:

  • Create project (or use an existing one)

  • Install Input System package.

  • Implement something that tries to leverage an XRHMD or XRController object

  • Switch platform to tvOS or QNX (ENABLE_VR conditional wont be defined on these platforms)

  • Execute code in Editor or in a build for the new platform.

    Expected result: No runtime errors

@Pauliusd01 I'm adding you just to make sure there's no breakage. Going through the tests mentioned in the PR description should be enough

Looks good. Just some non-blocking questions.
I also da Input QA to make a sanity check.

I'm understanding this correctly: this means that these API won't be published? Any reason why? I'm just out of context probably.

Hmm maybe I need to change this then. Besides the XRHMD devices, I started using this file to stop some xml errors I was getting from the yamato tests. I assumed the older define logic was hiding those same errors.

// Docs generation is skipped because these are intended to be replaced with the com.unity.xr.oculus package.

Thanks for removing this messy define. Are we ok with removing the UNITY_GAMECORE as well? I assume that was something Microsoft related?

Yes we only added UNITY_GAMECORE to these places so that when you're on the gamecore platform these classes will be compiled. Since we are no longer wrapping entire classes they will always be compiled.

I have no XR devices so only ran through non XR testing/sample scenes on windows playmode and player.
