我的导航系统是围绕 Aron Granberg 的 A* Pathfinder 项目（在 Unity 资产商店中找到的资产或简称为“webbing”）。其语法与 Unity 的 Navmesh 导航的读写方式非常相似。
下面的代码示例正确地将代理导航到 内的预定位置 List<T> 根据其 Vector3 排名 获得目标 。我的逻辑失败之处在于整个阵型不会像我目前所做的那样旋转。所有个体都会独立旋转和移动，但每次调用这些函数时，位置对齐都会保持在同一方向上。
TL;DR ：这会将单位移动到战术排列中，但不会旋转整个阵型。我想旋转整个阵型。

其意义跨越了党派界限：
public class PathOrganizer : MonoBehaviour
{
[SerializeField] GameObject destinationMarker = null;
IAstarAI agent;
MovementManager movement;
Vector3 callback = Vector3.zero;
private void Awake()
{
agent = GetComponent<IAstarAI>();
GetComponent<MovementManager>();
}
void Start()
{
transform.position = Selector.Instance.GetSelectedUnit().transform.position;
movement.ReachDestinationEvent += OnDestinationReached;
}
void OnDestinationReached(object sender, EventArgs e)
{
foreach (Transform child in gameObject.transform)
{
Destroy(child.gameObject);
}
}
public void ClearDestinationMarkers()
{
foreach(Transform child in gameObject.transform)
{
Destroy(child.gameObject);
}
}
public void AssignPosition(Vector3 point)
{
agent.destination = point;
GameObject waypoint = Instantiate(destinationMarker, point, Quaternion.identity);
waypoint.transform.SetParent(gameObject.transform, true);
waypoint.transform.eulerAngles = new Vector3(90, 0, 0);
callback = point;
}
public Vector3 ConfirmedPosition()
{
return callback;
}
public void SteerFormation()
{
agent.destination = Input.mousePosition;
}
}
变量 Vector3 回调 将向量返回到 MovementManager.cs ，从而完成移动。这部分也运行得很好。最后一种方法 ( SteerFormation ) 是我遇到的问题。您在那里看到的只是一个占位符命令，直到我最终能够在这个挑战中获得 \'W\'。我尝试了更复杂的旋转逻辑，包括查找方向和幅度或将其与相机的视野对齐。之前的失败和上面的失败确实会转动容器 GameObject ( PathOrganizer )，但其中的位置从未改变。
我认为问题在于，这些实例化的位置（通过 destinationMarker）反映了全球定位，实际上只不过是它们所在地面上的标记。我希望这些标记能够像公交车一样放在 PathOrganizer 内，而代理则是追赶公交车的狗。理论上，如果我驾驶公交车，整个羊群都会跟着我。我调查过类似的查询，但没有找到（或者可能没有理解）令人满意的解决方案。
