如何在unity中使用键盘控制物体的前后左右

      方法1：利用虚拟轴

void Update () {

        float hor = Input.GetAxis("Horizontal");

        float ver = Input.GetAxis("Vertical");

        transform.position += -transform.forward * ver * Time.deltaTime * 5;

        if (ver < 0)

        {

            hor = -hor;

        }

        transform.Rotate(transform.up * hor * Time.deltaTime * 45);

    }

 

方法2：设置键控制

       void Update () {

        if (Input.GetKey(KeyCode.W)|| Input.GetKey(KeyCode.UpArrow)) {

            transform.position += -transform.forward * Time.deltaTime * 10;

        }

        if (Input.GetKey(KeyCode.S)||Input.GetKey(KeyCode.DownArrow))

        {

            transform.position += transform.forward * Time.deltaTime * 10;

        }

        if (Input.GetKey(KeyCode.A)|| Input.GetKey(KeyCode.LeftArrow))

        {

            transform.Rotate(transform.up*Time.deltaTime*45);

        }

        if (Input.GetKey(KeyCode.D)|| Input.GetKey(KeyCode.RightArrow))

        {

            transform.Rotate(-transform.up * Time.deltaTime * 45);

        }

    }
