Question by dthisner · Jul 02, 2019 at 02:55 AM · nullreferenceexceptionspawningdeclaration

Getting null reference exception when spawning my player instead of having it in the scene

This is related to the course for Galaxy Shooter on Udemy.

I am spawning my player through the "Spawn Manager" I initiate the uiManager

 void Start()
     {
         _uiManager = GameObject.Find("Canvas").GetComponent<UIManager>();
 - check for null-
 }


Then when this function is triggered:

 public void DamagePlayer()
     {
         _uiManager.UpdateLives(_lives);
     }

I am getting: NullReferenceException and if I do: _uiManager = GameObject.Find("Canvas").GetComponent<UIManager>();

Before I call _uiManager.UpdateLives(_lives); then it works.


If I have the player being in the Game already and not being spawned by the Spawn Manager, then there is no NullReferenceException, why is that?
