Unity中lineOfSight射线未触发目标Debug.Log但wayPointFinder射线却触发的问题咨询

大家好，我在Unity项目里实现了一个GoToWayPoint函数，里面用到了多条射线检测，现在碰到一个很诡异的问题：lineOfSight这条射线对应的Debug日志完全没按预期触发，反而wayPointFinder射线会莫名其妙触发这条日志？而且RaycastHit lineOfSight的写法和另一条正常工作的borderFinder射线几乎一样，我实在排查不出问题所在。

具体细节：

• lineOfSight射线里有一句调试代码：Debug.Log("isBorder " + isBorder + " objectName: " + hitObjectName);，但实际运行时，这条日志是被wayPointFinder射线触发的，而非lineOfSight自身
• 另外，用于检测左右传感器的borderFinder射线是能正常识别到带trackBorder标签的碰撞体的

下面是完整的GoToWayPoint函数代码：

public void GoToWayPoint()
{
    // uses Rigidbody.MoveRotation
    HRLSpeedController speedController = gameObject.GetComponent<HRLSpeedController>();
    // Check if there are any waypoints in the array
    if (npcWayPoints.Length == 0) return;

    // Get the current waypoint
    GameObject currentWaypoint = npcWayPoints[currentWaypointIndex];

    // Find the GameObject with the "trackBorder" tag
    GameObject trackBorder = GameObject.FindGameObjectWithTag("trackBorder");

    RaycastHit wayPointFinder;
    Physics.Raycast(sensorWayPointFinder.transform.position, sensorWayPointFinder.transform.forward, out wayPointFinder, rayWayPointDistance);
    Debug.DrawRay(sensorWayPointFinder.transform.position, sensorWayPointFinder.transform.forward * rayWayPointDistance, new Color(1f, 0.65f, 0f));

    //Debug.Log("currentWaypointIndex: " + currentWaypointIndex + " currentVertexIndex: " + currentVertexIndex);

    if (isTurning)
    {
        // Get the current vertex
        GameObject currentVertex = vertex[currentVertexIndex];

        if (wayPointFinder.collider != null && wayPointFinder.collider.gameObject == currentVertex)
        {
            currentVertexIndex++;
            if (currentVertexIndex >= vertex.Length)
            {
                currentVertexIndex = 0;
            }
            currentVertex = vertex[currentVertexIndex];
        }

        // Calculate the direction from rbFuselage to currentVertex
        Vector3 direction = (currentVertex.transform.position - rbFuselage.position).normalized;
        // Calculate the target rotation
        Quaternion targetRotation = Quaternion.LookRotation(direction);
        // Interpolate between the current rotation of rbFuselage and targetRotation using Slerp
        rbFuselage.rotation = Quaternion.Slerp(rbFuselage.rotation, targetRotation, Time.deltaTime * rbFuselageRotationSpeed);
    }
    else
    {
        if (wayPointFinder.collider != null && wayPointFinder.collider.gameObject == currentWaypoint)
        {
            currentWaypointIndex++;
            if (currentWaypointIndex >= npcWayPoints.Length)
            {
                currentWaypointIndex = 0;
            }
            currentWaypoint = npcWayPoints[currentWaypointIndex];
        }

        // Calculate the direction from rbFuselage to currentWaypoint
        Vector3 direction = (currentWaypoint.transform.position - rbFuselage.position).normalized;
        // Calculate the target rotation
        Quaternion targetRotation = Quaternion.LookRotation(direction);
        // Interpolate between the current rotation of rbFuselage and targetRotation using Slerp
        rbFuselage.rotation = Quaternion.Slerp(rbFuselage.rotation, targetRotation, Time.deltaTime * rbFuselageRotationSpeed);
    }/**/
