Types

type Advanced 

type Advanced = class

Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.

type Any 

type Any interface {
	gd.IsClass
	AsXRInterface() Instance
}

type Capabilities 

type Capabilities = gdclass.XRInterfaceCapabilities //gd:XRInterface.Capabilities

const (
	/*No XR capabilities.*/
	XrNone Capabilities = 0
	/*This interface can work with normal rendering output (non-HMD based AR).*/
	XrMono Capabilities = 1
	/*This interface supports stereoscopic rendering.*/
	XrStereo Capabilities = 2
	/*This interface supports quad rendering (not yet supported by Godot).*/
	XrQuad Capabilities = 4
	/*This interface supports VR.*/
	XrVr Capabilities = 8
	/*This interface supports AR (video background and real world tracking).*/
	XrAr Capabilities = 16
	/*This interface outputs to an external device. If the main viewport is used, the on screen output is an unmodified buffer of either the left or right eye (stretched if the viewport size is not changed to the same aspect ratio of [method get_render_target_size]). Using a separate viewport node frees up the main viewport for other purposes.*/
	XrExternal Capabilities = 32
)

type EnvironmentBlendMode 

type EnvironmentBlendMode = gdclass.XRInterfaceEnvironmentBlendMode //gd:XRInterface.EnvironmentBlendMode

const (
	/*Opaque blend mode. This is typically used for VR devices.*/
	XrEnvBlendModeOpaque EnvironmentBlendMode = 0
	/*Additive blend mode. This is typically used for AR devices or VR devices with passthrough.*/
	XrEnvBlendModeAdditive EnvironmentBlendMode = 1
	/*Alpha blend mode. This is typically used for AR or VR devices with passthrough capabilities. The alpha channel controls how much of the passthrough is visible. Alpha of 0.0 means the passthrough is visible and this pixel works in ADDITIVE mode. Alpha of 1.0 means that the passthrough is not visible and this pixel works in OPAQUE mode.*/
	XrEnvBlendModeAlphaBlend EnvironmentBlendMode = 2
)

type Instance 

type Instance [1]gdclass.XRInterface

This class needs to be implemented to make an AR or VR platform available to Godot and these should be implemented as C++ modules or GDExtension modules. Part of the interface is exposed to GDScript so you can detect, enable and configure an AR or VR platform. Interfaces should be written in such a way that simply enabling them will give us a working setup. You can query the available interfaces through [XRServer]. 

var Nil Instance

Nil is a nil/null instance of the class. Equivalent to the zero value.

func New 

func New() Instance

func (Instance) ArIsAnchorDetectionEnabled 

func (self Instance) ArIsAnchorDetectionEnabled() bool

func (Instance) AsObject 

func (self Instance) AsObject() [1]gd.Object

func (Instance) AsRefCounted 

func (self Instance) AsRefCounted() [1]gd.RefCounted

func (Instance) AsXRInterface 

func (self Instance) AsXRInterface() Instance

func (Instance) EnvironmentBlendMode 

func (self Instance) EnvironmentBlendMode() gdclass.XRInterfaceEnvironmentBlendMode

func (Instance) GetCameraFeedId 

func (self Instance) GetCameraFeedId() int

If this is an AR interface that requires displaying a camera feed as the background, this method returns the feed ID in the [CameraServer] for this interface.

func (Instance) GetCapabilities 

func (self Instance) GetCapabilities() int

Returns a combination of [enum Capabilities] flags providing information about the capabilities of this interface.

func (Instance) GetName 

func (self Instance) GetName() string

Returns the name of this interface ([code]"OpenXR"[/code], [code]"OpenVR"[/code], [code]"OpenHMD"[/code], [code]"ARKit"[/code], etc.).

func (Instance) GetPlayArea 

func (self Instance) GetPlayArea() []Vector3.XYZ

Returns an array of vectors that represent the physical play area mapped to the virtual space around the [XROrigin3D] point. The points form a convex polygon that can be used to react to or visualize the play area. This returns an empty array if this feature is not supported or if the information is not yet available.

func (Instance) GetProjectionForView 

func (self Instance) GetProjectionForView(view int, aspect Float.X, near Float.X, far Float.X) Projection.XYZW

Returns the projection matrix for a view/eye.

func (Instance) GetRenderTargetSize 

func (self Instance) GetRenderTargetSize() Vector2.XY

Returns the resolution at which we should render our intermediate results before things like lens distortion are applied by the VR platform.

func (Instance) GetSupportedEnvironmentBlendModes 

func (self Instance) GetSupportedEnvironmentBlendModes() []any

Returns the an array of supported environment blend modes, see [enum XRInterface.EnvironmentBlendMode].

func (Instance) GetSystemInfo 

func (self Instance) GetSystemInfo() map[string]interface{}

Returns a [Dictionary] with extra system info. Interfaces are expected to return [code]XRRuntimeName[/code] and [code]XRRuntimeVersion[/code] providing info about the used XR runtime. Additional entries may be provided specific to an interface. [b]Note:[/b]This information may only be available after [method initialize] was successfully called.

func (Instance) GetTrackingStatus 

func (self Instance) GetTrackingStatus() gdclass.XRInterfaceTrackingStatus

If supported, returns the status of our tracking. This will allow you to provide feedback to the user whether there are issues with positional tracking.

func (Instance) GetTransformForView 

func (self Instance) GetTransformForView(view int, cam_transform Transform3D.BasisOrigin) Transform3D.BasisOrigin

Returns the transform for a view/eye. [param view] is the view/eye index. [param cam_transform] is the transform that maps device coordinates to scene coordinates, typically the [member Node3D.global_transform] of the current XROrigin3D.

func (Instance) GetViewCount 

func (self Instance) GetViewCount() int

Returns the number of views that need to be rendered for this device. 1 for Monoscopic, 2 for Stereoscopic.

func (Instance) Initialize 

func (self Instance) Initialize() bool

Call this to initialize this interface. The first interface that is initialized is identified as the primary interface and it will be used for rendering output. After initializing the interface you want to use you then need to enable the AR/VR mode of a viewport and rendering should commence. [b]Note:[/b] You must enable the XR mode on the main viewport for any device that uses the main output of Godot, such as for mobile VR. If you do this for a platform that handles its own output (such as OpenVR) Godot will show just one eye without distortion on screen. Alternatively, you can add a separate viewport node to your scene and enable AR/VR on that viewport. It will be used to output to the HMD, leaving you free to do anything you like in the main window, such as using a separate camera as a spectator camera or rendering something completely different. While currently not used, you can activate additional interfaces. You may wish to do this if you want to track controllers from other platforms. However, at this point in time only one interface can render to an HMD.

func (Instance) InterfaceIsPrimary 

func (self Instance) InterfaceIsPrimary() bool

func (Instance) IsInitialized 

func (self Instance) IsInitialized() bool

Returns [code]true[/code] if this interface has been initialized.

func (Instance) IsPassthroughEnabled 

func (self Instance) IsPassthroughEnabled() bool

Returns [code]true[/code] if passthrough is enabled.

func (Instance) IsPassthroughSupported 

func (self Instance) IsPassthroughSupported() bool

Returns [code]true[/code] if this interface supports passthrough.

func (Instance) OnPlayAreaChanged 

func (self Instance) OnPlayAreaChanged(cb func(mode int))

func (Instance) SetArIsAnchorDetectionEnabled 

func (self Instance) SetArIsAnchorDetectionEnabled(value bool)

func (Instance) SetEnvironmentBlendMode 

func (self Instance) SetEnvironmentBlendMode(value gdclass.XRInterfaceEnvironmentBlendMode)

func (Instance) SetInterfaceIsPrimary 

func (self Instance) SetInterfaceIsPrimary(value bool)

func (Instance) SetXrPlayAreaMode 

func (self Instance) SetXrPlayAreaMode(value gdclass.XRInterfacePlayAreaMode)

func (Instance) StartPassthrough 

func (self Instance) StartPassthrough() bool

Starts passthrough, will return [code]false[/code] if passthrough couldn't be started. [b]Note:[/b] The viewport used for XR must have a transparent background, otherwise passthrough may not properly render.

func (Instance) StopPassthrough 

func (self Instance) StopPassthrough()

Stops passthrough.

func (Instance) SupportsPlayAreaMode 

func (self Instance) SupportsPlayAreaMode(mode gdclass.XRInterfacePlayAreaMode) bool

Call this to find out if a given play area mode is supported by this interface.

func (Instance) TriggerHapticPulse 

func (self Instance) TriggerHapticPulse(action_name string, tracker_name string, frequency Float.X, amplitude Float.X, duration_sec Float.X, delay_sec Float.X)

Triggers a haptic pulse on a device associated with this interface. [param action_name] is the name of the action for this pulse. [param tracker_name] is optional and can be used to direct the pulse to a specific device provided that device is bound to this haptic. [param frequency] is the frequency of the pulse, set to [code]0.0[/code] to have the system use a default frequency. [param amplitude] is the amplitude of the pulse between [code]0.0[/code] and [code]1.0[/code]. [param duration_sec] is the duration of the pulse in seconds. [param delay_sec] is a delay in seconds before the pulse is given.
