Unity 中 XR 控制器移动的距离

Question

我一直在 Unity 中制作一个脚本来测量玩家在现实世界中使用像这样的 XRNodes 用右手移动了多远： InputTracking.GetLocalPosition(XRNode.RightHand) 在运动的开始，然后将其与结束位置进行比较现在我想移动距离，即使玩家绕着一圈移动。是使用 XRNodes 执行此操作的方法吗？测量游戏过程中移动的总距离？

是的，好吧，你可以简单地总结每一帧，比如

// Stores the overall moved distance
private float totalMovedDistance;

// flag to start and stop tracking
// Could also use a Coroutine if that fits you better
private bool track;

// Store position of last frame
private Vector3 lastPos;

public void BeginTrack()
{
    // reset total value
    totalMovedDistance = 0;
    
    // store first position
    lastPos = InputTracking.GetLocalPosition(XRNode.RightHand);

    // start tracking
    track = true;
}

public void EndTrack()
{
    // stop tracking
    track = false;

    // whatever you want to do with the total distance now
    Debug.Log($"Total moved distance in local space: {totalMovedDistance}", this);
}

private void Update()
{
    // If not tracking do nothing
    if(!track) return;

    // get current controller position
    var currentPos = InputTracking.GetLocalPosition(XRNode.RightHand);

    // Get distance moved since last frame
    var thisFrameDistance = Vector3.Distance(currentPos, lastPos);

    // sum it up to the total value
    totalMovedDistance += thisFrameDistance;

    // update the last position
    lastPos = currentPos;
}
