Oculus Go's controller not detected by OVRInput.IsControllerConnected()

I have a Unity game that runs on both Android Cardboard and Oculus Go. I'm trying to determine whether the Go's controller is connected.
I imported the Oculus integration package from the Unity asset store (though I'm not sure it's actually required... I've gotten the impression that Oculus support has been built into Unity since at least 2018.3, if not 2018.2 or earlier). I also deleted Cardboard and added Oculus as Virtual Reality SDKs in Player settings.
The following code executes in the Start() method that initializes most of my game:
void Start() {
// ...
if (OVRInput.IsControllerConnected(OVRInput.Controller.RTrackedRemote)) {
// do something visible
}
// ...
}
The problem is, OVRInput.IsControllerConnected(...) always returns false, and the code inside the block never executes.
Other things I've tried:
Moved the call to OVRInput.IsControllerConnected() from Start() to Update(), just in case it's an initialization-time issue. No success. Same result.
Instead of using OVRInput.Controller.RTrackedRemote as the argument, I tried the other objects... LTrackedRemote, Active, All, Gamepad, LTouch, RTouch, Remote, Touch, Touchpad, and None. All of them except '.None' returned false. '.None' returned true.
I set a breakpoint on the line calling OVRInput.IsControllerConnected() (after moving it to Update()), then called OVRInput.GetConnectedControllers() in VS2017's immediate window... it returned "None". Ditto for OVRInput.GetActiveController().
The game itself began as Android Cardboard. So far, the only major changes I've made to it are:
Importing the Oculus support library from Unity's Asset store.
In Player -> XR Settings, I deleted "Cardboard" and added "Oculus" as a VR SDK
In Build Settings, I changed the build method from 'Gradle' to 'Internal' (Gradle builds failed... I've seen posts from summer 2018 saying it's a Unity bug, but I'm not sure whether that's still current info... regardless, changing from Gradle to Internal made THAT error go away).
Most notably, I have NOT added any Oculus-specific prefabs, or changed/removed any of the GoogleVR-specific prefabs.

I know you tried moving IsControllerConnected to Update but did you try GetConnectedControllers in Update after a second? That's what did the trick for me. So in Update():
// initialize hand once after one second of start
if(!handInitialised){
initialWait += Time.deltaTime;
if(initialWait > 1f){
OVRInput.Controller c = OVRInput.GetConnectedControllers();
if(c == OVRInput.Controller.LTrackedRemote || c == OVRInput.Controller.LTouch){
//
}
//
handInitialised = true;
}
}

Unity:Time.timescale =0 not working

I am trying to display player tutorial when the user 1st starts the game using playerpref and want the game to be paused, the problem i am facing is that Time.timescale=0 is not pausing the game when placed inside start (tutorialCanvas gets displayed), but works when is called by a button(Pause button).
Following is the code I use
void Start()
{
if (PlayerPrefs.HasKey ("test4") ==false ) {
tutorialCanvas.SetActive (true);
Time.timeScale = 0;
}
}

Time.timeScale = 0 is really messed up for me so what i could recommend you is that if you just want to pause something like pausing a movement of a character then you can try it like this :
GameObject PlayerScript;
if(Input.GetKey(KeyCode.P)){
//lets disable the playermovement script only not the whole object
PlayerScript = GetComponent<PlayerMovement>().enabled = false;
}
I've been stucked there also so i made an alternative way. And you can also visit this one. If you want a free of that asset you can get it here

I had this issue recently, although it was only doing it on a build, and not in the editor. Changing timeScale to something like 0.0001f would fix it, but that wasn't a great solution. Creating an input settings asset (under Camera -> Player Input -> Open Input Settings) seemed to have fixed it for the builds.

Unity Start nog called on real build

I've made a dice app as a project to learn to work with unity (it was so good in my eyes that I put it on the google play store) but when I downloaded it from there, the Start function of at least 2 scripts isn't called and I have no idea whether the other Start functions are being called.
Here you can see 2 of the Start functions that aren't called
void Start()
{
light = light.GetComponent<Light>();
GetComponent<Button>().onClick.AddListener(TaskOnClick);
rawImage = GetComponent<RawImage>();
isLockMode = false;
rawImage.texture = getIconLock(isLockMode);
}
void Start()
{
Screen.fullScreen = false;
Dice.AddDie();
Input.gyro.enabled = true;
GlobalConfig.onShowShadowsChanged += onShadowsEnabledChange;
}
They work when I use Unity Remote on my smartphone and they also work when I just use unity without the remote...
the first script is attached to a UI element and the second script is attached to an empty GameObject called 'App'
It's also even more weird because they used to work but then I switched pc's (but used the same code).
I think something is wrong with the building itself

Found out the problem, the build was generating two files, an .apk and an other .odb or somethingl ike that (might be another extension). I had to untick 'split application binary' in the player settings

Unity Multiplayer FPS Client/Server Interaction Problems

I have a simple FPS where a player can fire a gun. I want the clients to see the bullet holes. I am trying to accomplish this by invoking a server side method when the client tries to fire the gun. The server side method should then raycast from the players camera and spawn a bullet hole for everyone to see..
I can get this to work partially by passing the player as a parameter to the server method. However, since my raycasting needs to be done based off the player camera, the bullet holes end up appearing at character height, since it's using the player and not the camera.
It won't allow me to pass a camera through. I have also tried creating an empty game object called bullet spawn and passing that through but I was getting a "object reference not set to instance of an object." This same error seems to surface for any Child element of the player I attempt to pass to the server side method.
I am unsure of the right way to accomplish this.
void Update()
{
if (isLocalPlayer)
{
if (Input.GetButton("Fire1"))
{
CmdFire(BulletSpawn);
}
}
}
[Command]
void CmdFire(GameObject Player)
{
Ray shooterRay = new Ray(Player.transform.position, Player.transform.forward);
if (Physics.Raycast(shooterRay, out Hit, 10000))
{
Debug.Log("player hit");
GameObject Bullet_Hole = (GameObject)Instantiate(BulletHole_Prefab, Hit.point, Quaternion.FromToRotation(Vector3.up, Hit.point));
NetworkServer.Spawn(Bullet_Hole);
}
}

Think about it this way. What is it that you need to fire your weapon? You need the firing point and the firing direction (in your simple case). So try to pass just that information. Your CmdFire should look like void CmdFire(Vector3 firingPoint, Vector3 firingDirection). Remember that when you pass the player gameobject, it gets serialized and sent to the server which causes a lot of unneeded network traffic. Stick to value types and simple objects for commands.
This is what ultimately led me to the solution. Thank you for the advice. I simply passed two Vector3 parameters as you suggested which represent the raycast position and direction. I can now shoot from both client and server and see the bullet holes on both as well. Here is the code that fixed it in case anyone runs into this later on:
void Update() {
if (isLocalPlayer) {
if (Input.GetButton("Fire1")) {
Vector3 FiringSpot = PlayerCam.transform.position;
Vector3 FireDirection = PlayerCam.transform.forward;
CmdFire(FiringSpot, FireDirection);
}
}
}
[Command]
void CmdFire(Vector3 firingPoint, Vector3 firingDirection) {
Ray shooterRay = new Ray(firingPoint, firingDirection);
if (Physics.Raycast(shooterRay, out Hit, 10000)) {
GameObject Bullet_Hole = (GameObject)Instantiate(bullet_Hole_Prefab, Hit.point, Quaternion.FromToRotation(Vector3.up, Hit.point));
NetworkServer.Spawn(Bullet_Hole);
Destroy(Bullet_Hole, 10);
}
}

Host's camera on network game isn't working correctly

So, I'm doing an FPS game in Unity5, and some days ago I started looking at multiplayer tutorials at the official site of Unity.
However, I changed some bit of the code to fit in an FPS, but I had a problem when started doing this. The client's camera moved fine, but the host's one did not: It used the client's camera to see, but his player to move, sort of a third-person view.
All players have the same code, and the camera has a Network Identity with Local Player Authority turned on. Also, it has this C# script:
using UnityEngine;
using System.Collections;
using UnityEngine.Networking;
public class VisionControl : NetworkBehaviour {
void Start () {
Cursor.lockState = CursorLockMode.Locked;
}
void Update () {
if(!isLocalPlayer){
return;
}
transform.Rotate (new Vector3 (-Input.GetAxis ("Mouse Y")*5.0f,0.0f,0.0f));
}
}

Your camera should not have a network identiy.
It is used only by the local clients to get a perspective of the game world, so they do not need to be networked.
Each camera exists on the current client.for the current client only.
Each game instance should have 1 camera running, that of the Local Player.
Attach a simple non-networked camera component to your player prefab and test again.

Fixed! I removed the VisionControl script and putted this one on the player's movement script:
public override void OnStartLocalPlayer ()
{
if (isLocalPlayer) {
FindObjectOfType<Camera> ().gameObject.transform.position = this.transform.position+new Vector3(0f,0.5f,0f);
FindObjectOfType<Camera>().gameObject.transform.SetParent (this.transform);
}
}
