问题 I'm adding objects to a scene for each entry in a database. I had a cube appearing in the scene for entry, but when I tried to add raycasting to click on objects it doesnt work, the objects dont appear and the console reads "Expression unavailable"..

I'm sure this is possible, but I do not have the VR developer skills yet to figure this one out! Thanks in advance for your help! 回答1:

问题 It's should be simple but I can't find any proper tutorial/sample for this. I imported the OVR package to my Unity scene, and put the OVRGearVrController in the middle of it. I can see the controller in my scene, but that's it.

问题 I am trying to show four videos at once using Google Cardboard. These videos are normal 2D videos that were shot on a normal 16:9 camera. What I want and need is to have one video in front of you then you turn your head 90 degrees and you see another video, turn again and see another until you hit the front video again.

问题 I am developing an Android application using Unity3D for the Samsung Gear VR, with the Samsung Galaxy S7. In my app, I use the bluetooth to create a local network between two devices. When the system popup asking permissions to enable bluetooth discoverability is supposed to appear in my app, the whole app freeze, the popup is not shown and I have to reboot the phone to use it again.
