Overhaul Main Menu #27

Closed GentleMoa closed 2 years ago

GentleMoa commented 2 years ago

Issues:

Make UI Canvas "World Space"
Spawn a conditional player (if there is an HMD connected --> spawn VR Player prefab // if there are more than 5 screens connected, spawn CAVE Player prefab)
Either have a button which creates a room with a random name OR
Have a virtual keyboard, which can be operated via VR controllers

Issue (For conditional player spawning):

I use Displayer.display.length to determine if there more displays connected than a specified number

However, "In the Unity Editor, displays is not supported; displays.Length always has a value of 1, regardless of how many displays you have connected." (Unity Documentation, link: https://docs.unity3d.com/ScriptReference/Display-displays.html)

---> Testing this code is impossible outside of the CAVE (Maybe send to Alex, because he has a multi-display setup)

Pitfall (For HMD registering)

Calling "InputDevices.GetDevicesWithCharacteristics(InputDeviceCharacteristics.HeadMounted, inputDevices);" only once in Start wont find the connected Oculus Quest headset.
Instead use a method to call it again for a few frames and then it will be registered!

Unknown Problem (For HMD registering):

After adding a "XRUI Input Module" to the Canvas, the HMD would never be found again. Even after removing the "XRUI Input Module" component and reconnecting the Headset.

Fix: Remove "XRUI Input Module" component, close and re-open Unity. Then it works again.

Issue (UI Button does not react to Controller Inputs)

Possible solution:

Rather than spawning a conditional player we could have a VR/CAVE player inactive in the scene and active one or the other conditionally. This way we could have the Event Camera of each player assigned to a version of the UI.
