Score counter breaking after adding points

Questions & Answers
1

I managed to make a score counter that adds 500 points when an object is destroyed. The destroy function only destroys the renderer and collider of the destructibles. However, upon activating the script to add 500 points when already at 500, instead of going to 1000, it goes to 0 and then to 500 again. The only way to get above 500 is to destroy several crates at once. Here is the script:

using UnityEngine;

using UnityEngine.UI;
using System.Collections;



public class ScoreCounter : MonoBehaviour {
public Text countText;
private int score;

	void Awake () {
		score = 0;
		SetCountText ();
	
	}

	void Update () {
		
	
	}

	void OnCollisionEnter (Collision coll) { 
	if (coll.relativeVelocity.magnitude > 25f && coll.other.tag == "Crate") {
	score = score + 500;
		SetCountText ();
		}
	}
	public void SetCountText ()
	{
	countText.text = "Score: " + score.ToString ();
	}
}

Why?! Please help, need an answer by tomorrow!
-EDIT- Now it doesn’t give me any points at all. I think this whole problem is because it’s attached to 41 objects at once, but I don’t know how to work around that. I barely was able to do this script as is.

maybe try

using UnityEngine;
 
 using UnityEngine.UI;
 using System.Collections;
 
 public class ScoreCounter : MonoBehaviour {
 public Text countText;
 private int score;
 
     void Awake () {
         score = 0;
         SetCountText ();
     
     }
 
     void OnCollisionEnter (Collision coll) { 
     if (coll.relativeVelocity.magnitude > 25f && coll.other.tag == "Crate") {
     500 += score;
         SetCountText ();
         }
     }
     public void SetCountText ()
     {
     countText.text = "Score: " + score.ToString ();
     }
 }

Hi. If you get this in time, you need to create an empty game object by going to the create tab (in the hierarchy view) and selecting empty game object. then add the new score script to that empty game object, not the crates.

create a new script the name CrateScript, thats very important, and attach that script to your crates. now on the crate, you will see the script attached (in the inspector view) and a field saying Score Script, drag the empty game object (from the hierarchy view, not the scene) directly onto that field that says Score Script.
Its probably i good idea to do that, then duplicate that crate a bunch of times, so you don’t have to repeat the process of dragging the empty game object onto the Score Script field.

  using UnityEngine;
  using UnityEngine.UI;
  using System.Collections;
  
  public class ScoreCounter : MonoBehaviour {
  public Text countText;
  int score = 0;
  
      public void SetCountText (int crateValue)
      {
      score += crateValue
      countText.text = "Score: " + score.ToString ();
      }

 using UnityEngine;
  using UnityEngine.UI;
  using System.Collections;
  
  public class CrateScript : MonoBehaviour {

      public ScoreCounter scoreScript;
      int crateValue = 500;

      void OnCollisionEnter (Collision coll) { 
      if (coll.relativeVelocity.magnitude > 25f && coll.other.tag == "Crate") {
      scoreScript.SetCountText(crateValue);
      Destroy(col.gameObject, 2);
          }
      }

  }
