Question

我正在制作一个游戏，玩家在该游戏中绕着行星旋转相机（相机支架的子代）。我需要能够在特定的时间点限制相机的位置（和旋转）。我正在使用RotateAround函数，我想知道是否有人可以帮助我解决这个问题？我的代码如下：

private void RotateCamera(Vector3 dragStartPosition, Vector3 dragEndPosition)
 {

     //normalised for odd edges
     dragEndPosition = dragEndPosition.normalized *planetRadius;
     dragStartPosition = dragStartPosition.normalized * planetRadius;

     // Cross Product
     Vector3 cross = Vector3.Cross(dragEndPosition, dragStartPosition);

     // Angle for rotation
     float angle = Vector3.SignedAngle(dragEndPosition, dragStartPosition, cross);

     //Causes Rotation of angle around the vector from Cross product
     holderTransform.RotateAround(planet.transform.position , cross, angle);

     EventHandler.instance.AddHiddenEvent(EventHandler.EventType.panCamera);
 }


 private static Vector3? GetMouseHit()
 {
     RaycastHit hit;
     int layer_mask = LayerMask.GetMask("Planet"); //raycasting on the planet
     if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hit, Mathf.Infinity, layer_mask))
     {
         return hit.point;
     }
     return null;
 }

使用Mathf.clamp（）函数。

unity-夹紧相机的RotateAround功能？
