如果玩家沒有在游戲場景中點擊，幾分鍾后會改變場景

Question

我想檢查用戶是否點擊了我的一個游戲對象（我有 15 個游戲對象），如果用戶在 10 秒內沒有點擊其中一個，則顯示文本，如果他點擊了我的一個游戲對象，他可以繼續玩。

這是代碼：

using UnityEngine;
using UnityEngine.EventSystems;

/// <summary>
/// Attach this component to "your game objects" along with collider.
/// Also, you have to attach
/// - PhysicsRaycaster (for 3D)
/// - Physics2DRaycaster (for 2D)
/// to your Main Camera in order to detect Click.
/// </summary>
public class ClickDetector : MonoBehaviour, IPointerClickHandler
{
    void IPointerClickHandler.OnPointerClick(PointerEventData eventData)
    {
        IdleDetector.NotifyClick();
    }
}

using UnityEngine;
using UnityEngine.UI;

/// <summary>
/// You may want to attach this component to empty GameObject.
/// You need only one instance of this component in the scene.
/// </summary>
public class IdleDetector : MonoBehaviour
{
    [SerializeField] float _timeoutSeconds = 10;
    [SerializeField] Text _console = default;
    static float _timer = 0f;
    static bool _isTimedout = false;

    void Update()
    {
        _timer += Time.deltaTime;

        if (_timer > _timeoutSeconds)
        {
            if (!_isTimedout)
            {
                // Show message.
                string message = $"{_timeoutSeconds} seconds elapsed without click.";
                Debug.Log(message);

                if (_console)
                {
                    _console.text = message;
                }

                _isTimedout = true;
            }

            // Do whatever you want on timeout.
        }
        else if (!_isTimedout && _console.text.Length > 0)
        {
            _console.text = "";
        }
    }

    public static void NotifyClick()
    {
        Debug.Log("Click.");
        _timer = 0f;
        _isTimedout = false;
    }
}

如果你想看看它是如何工作的，試試 unitypackage。
