游戏结束后如何阻止分数增加 [英] After Game Over how to stop score from increasing

问题描述

我正在制作无尽的亚军游戏，并且正在使用 ScoreManager对象，并且将对撞机2d设置为触发，因此每次对象被击中时得分都会提高。但是我希望它在健康状况达到0时停止增加分数。这是ScoreManager代码：

Im making a endless runner game and am using a 'ScoreManager' object with a box collider 2d set to 'is trigger' increasing the score every time a object hits it. But I want it to stop increasing the score if the health reaches 0. This is the ScoreManager code:

 public int score;
public Text scoreDisplay;

void OnTriggerEnter2D(Collider2D other)
{
    if (other.CompareTag("Obstacle"))
    {
        score++;
    }
}

private void Update()
{
    scoreDisplay.text = score.ToString();

}

我想添加一个：

public int health = 3; 

并在更新功能中：

if (health <= 0) {
        Destroy(gameObject);
    } 

但这似乎不起作用。

运行状况显示在播放器脚本中。

The health is displayed in a player script.

public class Player : MonoBehaviour
{
private Vector2 targetPos;
public float Yincrement;

public float speed;
public float maxHeight;
public float minHeight;

public Text healthDisplay;

public GameObject gameOver;

public int health = 3;
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
private void Update()
{
    healthDisplay.text = health.ToString();

    if (health <= 0) {
        gameOver.SetActive(true);
        Destroy(gameObject);
    }    

有什么想法吗？

推荐答案

只要定义了健康状况，就将其替换为一个属性，该属性会在设置为值<时启动一个事件。 0.像这样：

Wherever your health is defined, substitute it by a property that launches an event whenever set to a value < 0. Like this:

public class Player : MonoBehavior
{
    public delegate void PlayerDiedDelegate();
    public static event PlayerDiedDelegate onPlayerDied;

    private int _health;
    public int health
    {
        get
        {
            return _health;
        }
        set
        {
            _health = value;
            if(_health < 0)
            {
                onPlayerDied?.Invoke();
            }
        }
    }
}

现在您可以将场景中的任何控制器附加到事件：

Now you can attach any controller in your scene to the event:

public class ScoreController : MonoBehavior
{
    private void Awake()
    {
        Player.onPlayerDied += OnPlayerDied;
    }

    private void OnPlayerDied()
    {
        // Put your logic here: stop collecting score etc.
    }
}
