使用Physics.OverlapSphere来检测不方便调试, 其他都可以.

 

核心代码:

//检测敌人    public void CheckEnemy()     {        Collider[] cols = Physics.OverlapSphere(this.transform.position, attackRange);               if (cols.Length > 0)        {            foreach (var i in cols)            {                Debug.Log(i.gameObject.tag);                if (i.gameObject.CompareTag("Enemy"))                 {                    //检测到敌人在主角以attackRange半径的圆里面                }            }        }      }
