<brief_description>
|
|
A tracked object.
|
|
</brief_description>
|
|
<description>
|
|
An instance of this object represents a device that is tracked, such as a controller or anchor point. HMDs aren't represented here as they are handled internally.
|
|
As controllers are turned on and the [XRInterface] detects them, instances of this object are automatically added to this list of active tracking objects accessible through the [XRServer].
|
|
The [XRController3D] and [XRAnchor3D] both consume objects of this type and should be used in your project. The positional trackers are just under-the-hood objects that make this all work. These are mostly exposed so that GDExtension-based interfaces can interact with them.

Marks this pose as invalid, we don't clear the last reported state but it allows users to decide if trackers need to be hidden if we loose tracking or just remain at their last known position.

The unique name of this tracker. The trackers that are available differ between various XR runtimes and can often be configured by the user. Godot maintains a number of reserved names that it expects the [XRInterface] to implement if applicable:
|
|
- [code]left_hand[/code] identifies the controller held in the players left hand
|
|
- [code]right_hand[/code] identifies the controller held in the players right hand
