This commit adds the classes OpenXRExtensionWrapperExtension and OpenXRAPIExtension that can be used in GDExtensions to define OpenXR extension wrappers. It modifies extension wrapper registration so that they can be registered before OpenXRAPI instantiation (e.g. in core level initialization of GDExtensions).

<return type="Dictionary" />
|
|
<description>
|
|
Returns a [Dictionary] of OpenXR extensions related to this extension. The [Dictionary] should contain the name of the extension, mapped to a [code]bool *[/code] cast to an integer:
|
|
- If the [code]bool *[/code] is a [code]nullptr[/code] this extension is mandatory.
|
|
- If the [code]bool *[/code] points to a boolean, the boolean will be updated to [code]true[/code] if the extension is enabled.

<method name="_on_process" qualifiers="virtual">
|
|
<return type="void" />
|
|
<description>
|
|

|
|
<method name="_on_register_metadata" qualifiers="virtual">
|
|
<return type="void" />
|
|
<description>
|
|
Allows extensions to register additional controller metadata. This function is called even when the OpenXR API is not constructed as the metadata needs to be available to the editor.
|
|
Extensions should also provide metadata regardless of whether they are supported on the host system. The controller data is used to setup action maps for users who may have access to the relevant hardware.
