using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public Transform targetPosition;
    public float popupDistanceThreshold = 2f;
    public GameObject popupPanel;

    private void Update()
    {
        if (targetPosition == null || popupPanel == null)
        {
            Debug.LogError("Please assign the target position and popup panel in the Inspector.");
            return;
        }

        float distanceToTarget = Vector3.Distance(transform.position, targetPosition.position);

        if (distanceToTarget <= popupDistanceThreshold)
        {
            popupPanel.SetActive(true);
        }
        else
        {
