Question

如果这有所不同，我会使用统一5.1.2。

我有一个游戏对象盾牌，我想围绕一个玩家围成一圈。我有一定程度的工作，盾牌对输入反应良好，但没有动画，因为它只是传送到新位置而不是以平滑的方式绕圈移动。游戏是2D自上而下，所以只能在x / y平面上工作。曾试图使用lerp和slerp但没有获得任何快乐

真的很感谢你帮忙解决这个问题！

这是我到目前为止所拥有的：

public class ShieldMovement : MonoBehaviour {

    public Transform target; //player shield is attaced to

    float distance = 0.8f; // distance from player so it doesn't clip
    Vector3 direction = Vector3.up;


    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {

        float angle = Mathf.Atan2 (Input.GetAxisRaw("rightH"), Input.GetAxisRaw("rightV"))* Mathf.Rad2Deg;

        if(Input.GetAxis("rightH") != 0f || Input.GetAxis("rightV") != 0f)
        {
            direction =  new Vector3(Input.GetAxis("rightH"),Input.GetAxis("rightV"), 0.0f ) ;
        }

        Ray ray = new Ray(target.position, direction);
        transform.position = ray.GetPoint(distance);

        if(Input.GetAxis("rightH") != 0f || Input.GetAxis("rightV") != 0f)
        {
            transform.rotation = Quaternion.AngleAxis(angle,Vector3.forward*-1);
        }
    }
}

试试这个。通过对app.post('/somepath', function (req, res, next) { var hmacReceived = req.headers['x-shopify-hmac-sha256']; hmac = crypto.createHmac('SHA256',secret); req.on("data", function(data) { hmac.update(data); }); req.on("end", function() { var calculatedHmac = hmac.digest("base64"); var test1 = hmacReceived === calculatedHmac; }); req.on("error", function(err) { return next(err); }); }进行如此多的方法调用，您真的只想在开始时调用它一次并将其缓存到变量中以加快速度。另外，你真的不需要检查Input.GetAxis("...")两次，所以我将所有内容都放入其中一项检查中。我添加了if(Input.GetAxis("rightH") != 0f || Input.GetAxis("rightV") != 0f)的乘法，希望能为你找到顺利的东西

Answer 2

经过大量的搜索和一些帮助，我终于解决了问题，谢谢大家:)这是我提出的解决方案

public class ShieldMovement : MonoBehaviour {

public Transform target; //player shield is attaced to

float distance = 0.8f; // distance from player so it doesn't clip
Vector3 direction = Vector3.up;
public float circSpeed = 0.1f; // Speed Shield moves around ship


// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

    float rh = Input.GetAxisRaw("rightH");
    float rv = Input.GetAxisRaw("rightV");

    if(Mathf.Abs(rh) > 0.15f || Mathf.Abs(rv) > 0.15f)
    {
        Vector3 targetDir = new Vector3(rh, rv, 0.0f);
        direction  = Vector3.Slerp(transform.position-target.position, targetDir, circSpeed);

    }

    Ray ray = new Ray(target.position, direction); // cast ray in direction of point on circle shield is to go

    transform.position = ray.GetPoint(distance); //move shield to the ray as far as the radius

    float angleY = transform.position.y - target.position.y;
    float angleX = -(transform.position.x - target.position.x);

    float angle = Mathf.Atan2 (angleY, angleX) * Mathf.Rad2Deg-90; //Get angle

    if(Mathf.Abs(rh) > 0.15f || Mathf.Abs(rv) > 0.15f)
    {
        transform.rotation = Quaternion.AngleAxis(angle,Vector3.forward*-1); // keep shield facing outwards in respect to player, will need revisiting on animating shield properly
    }


}

}
