Unity C#TouchScript - 将对象移动到Flick的方向

我试图让对象读取轻弹(使用Unity上的Touchscript包) - 然后在方向上轻弹脚本附加的对象。

它肯定会读取轻弹,但我不知道如何读取/获取方向以将力添加到刚体上/将其平移到方向上。我看了一下像ScreenFlickVector& amp;没有运气的手势方向。我很乐意帮助你!

private Rigidbody rb;
    // Use this for initialization
    void Start () {
        rb= GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        transform.Translate(Vector3.down * Time.deltaTime);

    }

    private void OnEnable()
    {
        // subscribe to gesture's Tapped event
        GetComponent<FlickGesture>().Flicked += OnFlick;

    }
    private void OnDisable()
    {
        GetComponent<FlickGesture>().Flicked -= OnFlick;
    }

    private void OnFlick(object sender, EventArgs e)
    {
        // Implement the Flick

    }
}

访问FlickGesture信息可以这样做:

void OnFlick(object sender, System.EventArgs e)
{
    var gesture = sender as FlickGesture;

    float distanceFromCamera = Vector3.Distance(transform.position, Camera.main.transform.position);

    Vector3 wp1 = new Vector3(gesture.PreviousScreenPosition.x, gesture.PreviousScreenPosition.y, distanceFromCamera);
    wp1 = Camera.main.ScreenToWorldPoint(wp1);

    Vector3 wp2 = new Vector3(gesture.ScreenPosition.x, gesture.ScreenPosition.y, distanceFromCamera);
    wp2 = Camera.main.ScreenToWorldPoint(wp2);

    Vector3 velocity = (wp2 - wp1) / gesture.FlickTime;

    rigidbody.AddForce(velocity, ForceMode.VelocityChange);
}

通过获取手势的开始和结束位置并将这些位置转换为世界空间,然后应用经过手势时间的缩放,可以使对象的世界空间速度被轻弹。

我希望这能让你顺利上路。
