UnitySubsystemsManifest.json

UnitySubsystemsManifest.json contains metadata about your provider that can be queried before your plugin is loaded. The values in this dictionary are used to populate specific instances of SubsystemDescriptors in C#. For example, information within the displays list is used to populate XRDisplaySubsystemDescriptors.

Example .json file:

{
    "name": "PluginName",
    "version": "1.0.0",
    "libraryName": "UnityXRDisplayExample",

    "displays": [
        {
            "id": "Display0",
            "supportedMirrorBlitReservedModes" : ["leftEye","rightEye", "sideBySide"]
        }
    ],
    "inputs:": [
        {
            "id": "MockHMD Head Tracking Stationary"
        },
        {
            "id": "MockHMD Head Tracking Simulated"
        }
    ]
}
Metadata Descripción
name The name of your provider. Must match the first parameter of your native plug-in’s RegisterLifecycleHandler call. Likely to show up in UI in the future.
version Unused currently. Likely to show up in UI in the future.
libraryName Must match the name of your provider’s native plug-in binary without the extension.
displays Collection of Display subsystem providers.
id Identifier for this display plug-in configuration. The id must match the string you pass into your native plug-in’s RegisterLifecycleHandler call for that subsystem. You can have more than one display, as long as your native plugin calls RegisterLifecycleHandler for each.
inputs Collection of Input subsystem providers.

Your manifest file can include other displays after id - subsystems specify which parameters are valid.
