2d人物方向

人物  rigbody

脚本

private Rigidbody2D rb;
    private Animator anim;
    public float speed;
    private Vector2 movevelocity;
    // Start is called before the first frame update
    void Start()
    {
        anim = GetComponent<Animator>();
        rb = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        Vector2 moveInput = new Vector2(Input.GetAxisRaw("Horizontal"), 0);
        movevelocity = moveInput * speed;
        if(moveInput !=Vector2.zero)
        {
            anim.SetBool("walk", true);
        }
    }

    private void FixedUpdate()//让刚体移动
    {
        rb.MovePosition(rb.position + movevelocity * Time.fixedDeltaTime);
    }

 

再人物的animator内增加 bool
