I have created UI text object

enter image description here

And then created Text field in behavior class:

using UnityEngine.UI;

public class Explorer : MonoBehaviour
{
    public Material mat;
    public Text text;

...

void FixedUpdate () {
    ...
    text.text = string.Format("x {0}", scale);

If I just run it, it says

Object reference not set to an instance of an object

at runtime.

If I try to drag ZoomText to Text slot, it doesn't allow me:

If I first drag ZoomText from Hierarchy to Project

enter image description here

then it allows me to set Text slot, but still gives

Object reference not set to an instance of an object

at runtime.

If I am trying to set text field by Find

private void Start()
{
    text = (Text) GameObject.Find("ZoomText");
}

it gives me

Cannot convert type 'UnityEngine.GameObject' to 'UnityEngine.UI.Text'

What I am doing wrong? Suspect may be incorrect types, but how to know correct ones?

    \$\begingroup\$ In your Explorer class, you can take a GameObject instead of a Text, than in your Start/Awake, just call a GetComponent<WhateverYourTypeIs>() on it. \$\endgroup\$ Commented Oct 10, 2020 at 16:35

  • \$\begingroup\$ @formatc2013 this worked, but why so complex? why was I able to set material directly? \$\endgroup\$ Commented Oct 10, 2020 at 18:38

    \$\begingroup\$ An object in your project folder cannot reference an object in your scene - because scenes can come and go from memory, so you have no guarantee that scene object even exists when you want to read it. Object in the scene can reference each other, or objects in the project folder, but not the other way around. \$\endgroup\$ Commented Oct 10, 2020 at 19:07
