新添加-> EntityFX.cs

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

public class EntityFX : MonoBehaviour
{
    private SpriteRenderer sr;
    [Header("Flash Fx")]
    [SerializeField] private float flashDuration;
    [SerializeField] private Material hitMat;
    private Material originalMat;
    private void Start()
    {
        sr = GetComponentInChildren();//获取子组件 SpriteRender，为之后的对Render的操作做铺垫
        originalMat = sr.material;//获取sr中的material，材料。先保存起来以便以后换回去
    }
    private IEnumerator FlashFX()//用IEnumerator，目的在于将材料变为白色后经过一段时间能够变回去，时间由flashDuration控制
    {
        sr.material = hitMat;
        yield return new WaitForSeconds(flashDuration);//WaitForSeconds()函数，应该是等待一段时间后变为0，与yield配合。
        sr.material = originalMat;
    }
}

注意

由于本人C#不是很好，关于IEnumerator和StartCoroutine暂时就不深入了，我就按个人感觉进行注释了，如有错误，请多指正
