不用射线触发，主动传送到场景中预设的点  
新版本的强制传送

public virtual void ForceTeleport(Vector3 destinationPosition, Quaternion? destinationRotation = null)
            {
                DestinationMarkerEventArgs teleportArgs = BuildTeleportArgs(null, destinationPosition, destinationRotation);
                StartTeleport(this, teleportArgs);
                Quaternion updatedRotation = SetNewRotation(destinationRotation);
                Vector3 finalDestination = GetCompensatedPosition(destinationPosition, destinationPosition);
                CalculateBlinkDelay(blinkTransitionSpeed, finalDestination);
                Blink(blinkTransitionSpeed);
                if (ValidRigObjects())
                {
                    playArea.position = finalDestination;
                }
                ProcessOrientation(this, teleportArgs, finalDestination, updatedRotation);
                EndTeleport(this, teleportArgs);
            }

老版本的强制传送

public virtual void ForceTeleport(Vector3 destinationPosition, Quaternion? destinationRotation = null)
            {
                DestinationMarkerEventArgs teleportArgs = BuildTeleportArgs(null, destinationPosition, destinationRotation);
                StartTeleport(this, teleportArgs);
                CalculateBlinkDelay(blinkTransitionSpeed, destinationPosition);
                Blink(blinkTransitionSpeed);
                if (ValidRigObjects())
                {
                    playArea.position = destinationPosition;
                }
                Quaternion updatedRotation = SetNewRotation(destinationRotation);
                ProcessOrientation(this, teleportArgs, destinationPosition, updatedRotation);
                EndTeleport(this, teleportArgs);
            }

后设置camerarig角度，导致每次传送的位置有偏差，所以更新下vrtk版本，解决这个问题。

如果在强制传送的，想同时调整相机的角度，即 同时调整传送后相机角度与位置

public void Teleport(Transform trans)
        {
            Quaternion tempQ = Quaternion.Euler(trans.eulerAngles); 
            m_teleport.ForceTeleport(trans.position, GetRotation(trans));
        }
    
        Quaternion GetRotation(Transform trans)
        {
            float offset = ( m_playArea != null && m_headset != null ? m_playArea.eulerAngles.y - m_headset.eulerAngles.y : 0f);
            return Quaternion.Euler(0f, trans.eulerAngles.y + offset, 0f);
        }

m\_headset 为camera（eye）  
m\_playArea为cemerarig  
计算传送后应该补偿的夹角得到新的rig方向

传送后即为箭头预设方向
