unity.system; Не работают ивенты

Есть две части кода:

using UnityEngine;
using UnityEngine.Events;
public class cubeCollisionDetector : MonoBehaviour
{
    public UnityEvent scoreUp;
    public UnityEvent scoreDown;
    private string cubeName;
    private string[] cubeNameMassive;
    public void OnCollisionEnter(Collision collision)
    {
        if (collision.transform.tag == "sphere")
        {
            cubeName = gameObject.name;
            Destroy(GameObject.Find(gameObject.name));
            string nameToCount = gameObject.name.Split('(')[0];
            string[] cubeNameMassive = nameToCount.Split('/');
            string colour = cubeNameMassive[3];
            if (colour.Contains("red"))
            {
                scoreUp.Invoke();
            }
            else if (colour.Contains("green"))
            {
                scoreDown.Invoke();
            }
        }
    }
}

и

using UnityEngine;
using UnityEngine.UI;
public class scoringScript : MonoBehaviour
{
    static private int scoring = 0;
    public void scoringUpMethod()
    {
        scoring++;
        Debug.Log(scoring);
        GetComponent<Text>().text = "scoring: " + scoring.ToString();
    }
    public void scoringDownMethod()
    {
        scoring--;
        Debug.Log(scoring);
        GetComponent<Text>().text = "scoring: " + scoring.ToString();
    }
}
