unity实现角色的移动（用状态机控制动画）

private CharacterController cc;//角色控制组件
    private Animator animator;//角色的动画组件
    public float speed = 5;//移动速度

    private AnimatorStateInfo animStateInfo;//获取动画状态信息
    

    void Awake()
    {
        cc = this.GetComponent();
        animator = this.GetComponent();
    }


    void Update()
    {
        float h = Input.GetAxis("Horizontal");
        float v = Input.GetAxis("Vertical");
        animStateInfo = animator.GetCurrentAnimatorStateInfo(0);

        if (Mathf.Abs(h)>0.1f|| Mathf.Abs(v) > 0.1f)//判断有键按下
        {
            animator.SetBool("Walk", true);
            if (animStateInfo.IsName("Walk"))
            {
                Walk(h, v);
            }            
        }
        else
        {
            animator.SetBool("Walk", false);
        }

        if (Input.GetAxis("Attack")==1)
        {
            //如果按了攻击键则执行攻击方法
            Attack();
        }


    }

    private void Walk(float h,float v)
    {
        Vector3 targetDir = new Vector3(h, 0, v);
        transform.LookAt(targetDir + transform.position);//向移动方向看
        cc.SimpleMove(transform.forward * speed);//向前移动
    }

    private void Attack()
    {
        animator.SetTrigger("Attack1");
    }
