Enable VR with scripting?

Unity 5.1 has integrated VR, its in the Build Player Settings as a checkbox. I want a startup scene that is not VR, then when the user starts it enables the VR camera. How can I do that?

 

with the checkbox checked put "VRSettings.enabled = false;" in startup and VRSettings.enabled = true; when you want to enable VR mode.

 

thanks for the responses. The VRSettings.enabled is working fine for me.

@Ed, what are the possible values for device? i heard that GearVR has been added as a device but that would be Android, versus Oculus is just desktop. Are there any plans to include Cardboard natively for Android and iOS?

 

The cardboard Unity asset includes distortion code for lens correction. This need to be done. A standard stereo device type will not look optimal. The distortion code also varies for the different cardboard lenses. v1 and 2

 

What about OpenVR / SteamVR? For now, I prefer their SteamVR plugin (and would actually prefer to have the native Unity integration be designed much more like that). But eventually, it would be nice to have it all integrated natively into Unity.

It also seems that sometimes, the native integration conflicts with the SteamVR plugin: I just recently had the case that I had "Virtual Reality Supported" switched off but it looked as if both was trying to render to the HMD with quite a bit of odd flickering going on ... but that could also have been something else - I just never saw that when using the SteamVR plugin in Unity 5. I'll probably add VRSettings.loadedDevice = VRDeviceType.None; in startup just to be sure.

Another really important one is Sony Project Morpheus, of course.

 

I'm working with the Note 4 / Gear VR in 5.1.2. If you check VR Supported in the Player Settings, the Android Device asks you to place your phone in the Gear VR before the game begins... What if you have some levels in VR and some in Non-VR, and want to start in a Non-VR menu?

My test today was an .apk with VR Support unchecked in the player settings. The user starts in a non-VR level. When the user loads a VR level, I have a script in said VR level where the Start() function sets VRSettings.enabled = true and also sets VRSettings.loadedDevice to VRDeviceType.Oculus.

However, once I start my VR level and this code executes, I do not see dual cameras rendering. Additionally, inserting my phone into the Gear VR once my VR level is loaded will launch the Oculus VR Home app. Prior to inserting my device into the Gear VR when my VR level loads, my logcat actually shows the same OVR reference errors from the Android Personal Edition bugs that Ed Unity and I worked through in versions before 5.1.2

Maybe it's not a bug since I could understand the argument that my implementation is an edge case, but.... Repro steps:

VR supported unchecked.
Scene 0: Scene 0 is non VR, using new Unity GUI elements to load a VR-enabled level (call it Scene 1)
Scene 1: When Scene 1 loads, code is executed to enable VR and set device type = oculus.
Symptom - No dual camera rendering. No Prompt to insert device into Gear VR. When the user inserts the device into the Gear VR voluntarily, the Oculus VR Home App launches.

 

Thanks for the response, Ed Unity. I guess I'm looking at making two separate yet companion apps (which is annoying but not the end of the world).

Application.persistentDataPath is the right place for me to share something like a flat JSON file where the two apps could share data about one another's progress, correct?

 

Do you know if there are any plans to support this functionality in the future?

 

Thank you! That's great to hear!!!

 

That's pretty annoying. I wanted players to use VR if they have a headset, now I'll need to make a separate app and sell it separately, which will not please my player base.

 

This does not work well , please see my post in the VR forums, The problem is the app launches to VR and then only kicks out of it and into regular play. That is an unacceptable user experience. I need the app to launch smoothly into regular game play. This is for oculus.

Hi,

I was wondering if changing between VR and Non-VR is still not support on GearVR.

I'm trying to start an app with Non-VR and then activate it via script but even when I use VRSettings.enabled=false and VRSettings.loadedDevice=VRDeviceType.None the first thing the apps does is asking you to put the pone in the GearVR so then you see the Non-VR app through the glasses and if I get the pone out the app just closes automatically.

So basically I would like to know if this is something doable or it is imposible so I don't keep trying to do something that I won't get done.

Thanks!

 

Unlike daydream or cardboard, for gear vr Oculus does not allow you to do this. Perhaps one day they'll change their mind, you could try contacting them. Unity isn't the party holding this up.

Thanks for the answer!

I've left my comment there too just in case it helps.

 

I'd love to be able to do this, personally. In my case my goal is to have separate scenes where I can have a VR scene with the same objects, but another scene dedicated just for testing/debug which is more isolated where I don't have to enter VR. For now, I'm limited to manually going into Edit -> Project Settings -> Player -> XR Settings in order to enable/disable VR so I can have more direct control (or if my laptop isn't currently connected to my eGPU/Vive).

¯\_(ツ)_/¯
