VistasUnity Multiplayer MLAPI Could not get NetworkObject for the NetworkBehaviour
For my PlayerController script, I changed inheriting from MonoBehaviour to NetworkBehaviour
public class PlayerController : MonoBehaviour
{
From this, to this:
public class PlayerController : NetworkBehaviour
{
Even though my player controller object does have a NetworkObject component.
Its throwing an error saying that it doesn't have one.
NullReferenceException: Could not get NetworkObject for the NetworkBehaviour. Are you missing a NetworkObject component?

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)
Its throwing this error as soon as I click on "Start Host" on the Network Manager script/object.
How can I fix this issue?

For some reason. There was a race condition that made GetComponentInParent return null. So I edited NetworkBehaviour.cs to use GetComponent instead.
/// <summary>
/// Gets the NetworkObject that owns this NetworkBehaviour instance
/// </summary>
public NetworkObject NetworkObject
{
get
{
if (m_NetworkObject == null)
{
//m_NetworkObject = GetComponentInParent<NetworkObject>();
m_NetworkObject = GetComponent<NetworkObject>();
}
if (m_NetworkObject == null)
{
throw new NullReferenceException($"Could not get {nameof(NetworkObject)} for the {nameof(NetworkBehaviour)}. Are you missing a {nameof(NetworkObject)} component?");
}
return m_NetworkObject;
}
}
