using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using TMPro;

public class DamagePopup : MonoBehaviour
{
[SerializeField] GameObject dmgPopup; //a prefab

public void Popup(Vector3 position, float damage)
{
var Clone = Instantiate(dmgPopup, position, Quaternion.identity); //clone reference
Clone.transform.SetParent(GameObject.Find("Canvas").transform);
Vector2 randomForce = new Vector2(Random.Range(-1f, 1f), Random.Range(5f, 10f));
Rigidbody2D CloneRb = Clone.GetComponent<Rigidbody2D>(); //this works fine
CloneRb.AddForce(randomForce, ForceMode2D.Impulse);
Clone.GetComponent<TextMeshPro>().SetText(damage.ToString()); //this line throws the error
Destroy(Clone, 2);
}
}

 

nevermind. figured it out myself

 

For future reference:

The answer is always the same... ALWAYS!

How to fix a NullReferenceException error

Three steps to success:
- Identify what is null <-- any other action taken before this step is WASTED TIME
- Identify why it is null
- Fix that
