OnCollisionStay 和协程问题

如何解决OnCollisionStay 和协程问题

大家好，我有一个小问题。只要玩家每 X 秒站在平台游戏上，我就试图让平台游戏对玩家造成伤害，现在它可以工作，但只要我继续移动，如果玩家只是站在那里什么都不会发生。

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

public class PlatformerManager : MonoBehavIoUr
{

    bool canTakeDmg = true;
    


    private void OnCollisionStay2D(Collision2D collision)
    {
        if (collision.gameObject.tag == "Player")
        {
            var healthComponent = collision.gameObject.GetComponent<PlayerManager>();

            if (healthComponent != null && canTakeDmg)
            {
                healthComponent.Getdamage(1);
                StartCoroutine(WaitForSeconds());
            }
        }



        IEnumerator WaitForSeconds()
        {
            canTakeDmg = false;
            yield return new WaitForSecondsRealtime(3);
            canTakeDmg = true;
        }
    }
}

玩家运动 - 对于我在玩家运动上做错的情况。

    {
        if (horiznotal>0 &&!isFacingRight || horiznotal < 0 && isFacingRight)
        {
            isFacingRight = !isFacingRight;

            Vector3 scale = transform.localScale;

    {
        currentHealth -= amount;

        if (currentHealth <=0)
        {
            //Dead animation 
            //GameOverScreen
        }
    }
}

解决方法

您应该删除代码并重新开始。

这可能有效：

void OnCollisionStay2D(Collision2D collision)
{
    if (collision.gameObject.tag == "Player")
    {
        if (canTakeDmg)
        {
            TakeDamage();
        }
    }



    void TakeDamage()
    {
        var healthComponent = collision.gameObject.GetComponent<PlayerManager>();
        yield return new WaitForSecondsRealTime(3);
        healthComponent.GetDamage(1);
    }
}
