左右移动

    // Update is called once per framevoid Update(){float inputX = Input.GetAxis("Horizontal");//切换方向if (inputX > 0)transform.localScale = new Vector3(-1.0f, 1.0f, 1.0f);else if (inputX < 0)transform.localScale = new Vector3(1.0f, 1.0f, 1.0f);//移动m_body2d.velocity = new Vector2(inputX * m_speed, m_body2d.velocity.y);}

跳

    void Update(){if (Input.GetKeyDown("space")){m_body2d.velocity = new Vector2(m_body2d.velocity.x, m_jumpForce);}
