Question

我对自己的代码有疑问。现在，我使一个文本UI在碰撞后显示在屏幕上，并且我还想让文本在2秒钟后消失，以便在再次发生新的碰撞后可以再次显示它。那么，我该如何设置计时器来获取此功能？非常感谢！

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class CollisionWithPlayer : MonoBehaviour
{
    int score;

    // Start is called before the first frame update
    void Start()
    {
        score = 0;
        GameObject.Find("message").GetComponent<Text>().text ="";
        GameObject.Find("collect").GetComponent<Text>().text = "";
        GameObject.Find("score").GetComponent<Text>().text = "";

    }

    // Update is called once per frame
    void Update()
    {

    }

    void OnCollisionEnter(Collision collision)
    {
        print("Collided with " + collision.collider.gameObject.tag);
        if (collision.collider.gameObject.tag == "pick_me")
        {
            GameObject.Find("collect").GetComponent<Text>().text = "You have collected an object!";
            Destroy(collision.collider.gameObject);
            //yield return new WaitForSeconds(2);
            //Destroy(GameObject.Find("collect"));
            score++;
            GameObject.Find("score").GetComponent<Text>().text = "score = " + score;
            print("Score " + score);

        }
        if (collision.collider.gameObject.name == "end" && score == 4)
        {
            print("Congratulations!");
            GameObject.Find("message").GetComponent<Text>().text = "Congratulations!";
        }
    }
}

在我的代码中，我有4个球属于“ pick_me”。我想要文本“您已经收集了一个物体！”出现在玩家与球碰撞时，然后在2秒后消失，下一次，玩家与另一个球碰撞，文本再次出现。那我该怎么办？

您应将coroutine与WaitForSeconds一起使用。例如：

IEnumerable OnCollisionCoroutine()
{
    // Do stuff here to make the text visible

    yield return new WaitForSeconds(2);

    // Do stuff here to hide the text
}

然后，当检测到冲突时，调用：

StartCoroutine(OnCollisionCoroutine());
