Package Dependencies

✨ Features

  • Added `ToggleComponentZone` sample script to activate/deactivate the Gaze Interactor GameObjects when entering a trigger collider to prevent unintentional gaze-based selection in the rest of the scene. This component was added to the Starter Assets and implemented in the `DemoScene` at the re-added "Gaze Interactable Objects" station. (Forward port from 2.6.5)

📈 Improvements

  • Changed the Climb Provider component in the `XR Origin (XR Rig)` prefab in the Starter Assets sample to also disable the Move provider when climbing.
  • Changed the `DemoScene` in Starter Assets to disable the Gaze Interactor by default so it is not causing accidental selection of interactables based on head movement.

🔧 Bug Fixes

  • Fixed an issue where pinching with the Hand Interaction Profile caused the Interactables to stick to the thumb longer than desired, moving the object after a pinch was released. The `ReleaseThresholdButtonReader` sample component was updated with new default values to ensure tighter press and release when pinching. (XRIT-334)
  • Fixed the Near-Far Interactor components to destroy the `Attach` and `Stabilization Cast Origin` GameObjects under the XR Origin that it creates when it is destroyed. This fix added new `OnDestroy` methods to [`InteractionCasterBase`](xref:UnityEngine.XR.Interaction.Toolkit.Interactors.Casters.InteractionCasterBase) and [`InteractionAttachController`](xref:UnityEngine.XR.Interaction.Toolkit.Attachment.InteractionAttachController). Users who had already implemented either method in derived classes will need to call the base method. (XRIT-322)
  • Fixed a compiler issue with the `KeyboardOptimizer` sample component that occurs when TextMeshPro or Unity UI packages are not installed.
  • Fixed an issue with the **AR Starter Assets** spawning components, where a compiler dependency on the `ObjectSpawner` component in **Starter Assets** was causing an inability to run Project Validation rules to import the required sample dependency.
  • Fixed hand prefabs in the `Hands Interaction Demo` sample that were based on the hand models from the XR Hands `HandVisualizer` sample. The new prefabs are built as a prefab variant, allowing smoother upgrade when the underlying models are updated. (Backport from 3.4.0-pre.1)
