Question

我已经制作了这个脚本来检查玩家和陷阱之间的碰撞并移除玩家hp。它运作完美，但惠普几乎立即下降。我尝试使用协程，但我不知道如何使它工作。

using UnityEngine;
using System.Collections;
using System;

public class hp_loss : MonoBehaviour 

{

public float loss_hp = 1;


    void OnTriggerStay2D(Collider2D other)
    {
        GameObject gObj = other.gameObject;

        if (gObj.CompareTag("enemy") && hajs.hp > 0)
        {
            hajs.hp = hajs.hp - loss_hp;
        }
    }
}

我怀疑你想要OnTriggerStay2D，因为它会多次发射。

IEnumerator OnTriggerEnter2D(Collider2D other)
    {
        yield return new WaitForSeconds(2f);

        GameObject gObj = other.gameObject;

        if (gObj.CompareTag("enemy") && hajs.hp > 0)
        {
            hajs.hp = hajs.hp - loss_hp;
        }
    }

我会以这种方式去做某事

Answer 3

greendhsde的答案应该做的工作，但只是在你想要在OnTriggerStay2D函数中完成所有这些工作而不需要更多的函数和更少的代码，这段代码也应该没问题。 decreaseTime越高，更新的时间越短。如果decreaseTime设置为2秒，则每2秒更新一次。

float decreaseTime = 0.2f;
float startCounter = 0f;
public float loss_hp = 1;

void OnTriggerStay2D(Collider2D other)
{
    //Dont decrease if  startCounter < decrease Time
    if (startCounter < decreaseTime)
    {
     startCounter += Time.deltaTime;
     return;
    }
    startCounter = 0; //Reset to 0

     //Don't decrease if score is less or equals to 0
    if (hajs.hp <=0)
    {
       return;
    }

    GameObject gObj = other.gameObject;
    if (gObj.CompareTag("enemy"))
    {

        hajs.hp = hajs.hp - loss_hp;
    }
}

碰撞后等待几秒钟
