public class ScoreChanger : MonoBehaviour
{
    int hits = 0;
    [SerializeField] private TextMeshProUGUI scoreText;

    private void Start()
    {
        UpdateScoreText();
    }

    private void OnCollisionEnter(Collision other)
    {
        hits++;
        UpdateScoreText();
    }

    void UpdateScoreText()
    {
        scoreText.text = hits.ToString();
