 using UnityEngine;

 public class callback : MonoBehaviour {
     public bool IsSuccessCallBack = true;
     private delegate void VoidDelegate();
     [ContextMenu("Build")]
     public void Build()
     {
         StartCoroutine(Builder(SuccessCallBack, FailureCallBack));
     }

     private IEnumerator Builder(VoidDelegate success, VoidDelegate failure)
     {
         if (!IsSuccessCallBack)
         {
             failure();
             yield break;
         }
         //前面是种种导致执行失败的判断
         success();
     }

     private void SuccessCallBack()
     {
         Debug.Log("该函数执行成功");
     }

     private void FailureCallBack()
     {
         Debug.Log("该函数执行失败");
     }
 }
