unity中控制人物移动有很多方法，经过这么长时间的学习后，我总结了一些；

1. 利用transform的translate方法控制人物移动；(结合动画的控制就不说了)

 float mx = Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime;float mz = Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime;transform.translate(mx,0,mz);

2.利用Rigidbody组件rigidbody.MovePosition()方法进行移动(包含动画控制部分),鼠标控制人物移动；

void  FixedUpdate()
{float h=Input.GetAxis("Horizontal");float v=Input.GetAxis("Vertical");Move(h,v);Turning();Animating(h,v);
}
void Move(float h,float v)
{Vector3 movement;movement.Set(h,0,v);movement=movement.normalized*speed*Time.deltaTime;rigidbody.MovePosition(transform.position+movement);
}
void Turning()
{Ray camRay=Camera.main.ScreenPointToRay(Input.mousePosition);RayCastHit hitInfo;if(Physics.RayCast(camRay,out hitInfo,distance,floorMask)){Vector3 playerToMouse=hitInfo.point-transform.position;playerToMouse.y=0;Quaternion newRotation=Quaternion.LookRotation(playerToMouse);rigidbody.MovePosition(newRotation);}
}
void Animating(float h,float v)
{bool walking=h!=0||v!=0;m_ator.SetBool("Walk",walking);
}

3.还有一种就是利用Rigidbody的velocity属性来控制人物移动了

 float moveSpeed =10;Animator m_ator;Rigidbody rigid;Vector3 m_Pos;void Start () {m_ator = transform.GetComponent<Animator>();rigid = transform.GetComponent<Rigidbody>();m_Pos = transform.position;}void Update () {float mx = Input.GetAxis("Horizontal") ;float mz = Input.GetAxis("Vertical") ;Vector3 nowVelocity = rigid.velocity;if (Mathf.Abs(mx) > 0.01f || Mathf.Abs(mz) > 0.01f){m_Pos = transform.position;transform.LookAt(m_Pos+new Vector3(mx, 0, mz));rigid.velocity = new Vector3(mx * moveSpeed, nowVelocity.y * moveSpeed, mz * moveSpeed);m_ator.SetBool("Walk",true);}else {rigid.velocity = new Vector3(0,nowVelocity.y*moveSpeed,0);m_ator.SetBool("Walk",false);}}
