1. Unity人物移动+自动寻路

        _NMA = GetComponent<UnityEngine.AI.NavMeshAgent>();
        //IsRunBoolID = Animator.StringToHash("IsRun");  //Hash-1
    }//end_Start

                _NMA.Resume();              
            }            
        }

        //WASD控制移动
        hor = Input.GetAxis("Horizontal");
        ver = Input.GetAxis("Vertical");
        //hor或ver不为0,表示有从wasd的输入,所以要终止导航,自己操作

            _NMA.Stop();

            //移动和旋转
            transform.Translate(0, 0, ver * MoveSpeed * Time.deltaTime);
            transform.Rotate(0, hor * RoteSpeed * Time.deltaTime, 0);
        }
        else
        {
            //如果wasd输入为0,才可能会自动导航
            //导航的速度为0的时候,不奔跑;不为0,奔跑
            if (_NMA.desiredVelocity!=Vector3.zero)
            {
                IsRun = true;
            }
            else
            {
                IsRun = false;
            }
        }       
    }//end_Update

2. 通过角色控制器控制移动
