Unity

Changes

1. [Important] Getting runtime status is changed:

   • Real Connection:

     • Passive: developer can listen to event WaveVR_Utils.Event.ALL_VREVENT to get the connection status of Head, Dominant Controller and NonDominant Controller
     • Proactive: developer should use WaveVR_Controller.Input().connected to get the connection status of Head, Dominant Controller and NonDominant Controller

   • Valid Pose:

     • Passive: developer can listen to event WaveVR_Utils.Event.DEVICE_CONNECTED to check whether the pose of Head, Dominant Controller and NonDominant Controller is valid.
     • Proactive: developer should use WaveVR.Instance.getDeviceByType ().connected to check whether the pose of Head, Dominant Controller and NonDominant Controller is valid.

   • Left-Handed Mode:

     • Passive: developer can listen to event WaveVR_Utils.Event.DEVICE_ROLE_CHANGED to get the device role change event.
     • Proactive: developer should use WaveVR_Controller.IsLeftHanded to check left-handed mode. (True: left-handed)

2. Assume developer uses InputModuleManager and set parameters as below:

   • Custom Input Module: Gaze
   • BtnController: True (means using controller button to controll)
   • With Time Gaze: False (means no timer)

   In runtime, if controller disconnected, Gaze module would use timer.

3. Set HMD enter button to trigger Gaze as default.

In right-handed mode, the “Dominant” hand will be right device. In left-handed mode, the “Dominant” hand will be left device. Here is the change file list. If developer used these files of previous version SDK to make customized prefabs, developer would have to check the value of fields in prefabs due to old types are removed from SDK3.0

7. [Important] changed public variables name of Script:

   • WaveVR_ControllerLoader.cs
   • WaveVR_Beam.cs
   • WaveVR_ControllerPointer.cs

   Developer should check source code to which is related.

8. In ControllerLoader.prefab, developer can customize beam & pointer.

9. WaveVR_Beam.cs and WaveVR_ControllerPointer.cs is unbundled from WaveVR event system.

   Developer can not set raycast mode and related settings in WaveVR_Beam and WaveVR_ControllerPointer anymore. Developer should review related source code about using WaveVR_Beam and WaveVR_ControllerPointer.
