如何在 XNA 中仅在几分钟后移动相机？
我将相机放置在距物体 10 个单位的位置，但不在物体后面。我不希望在物体旋转时相机位置立即位于物体后面，我希望当我旋转物体时，相机位置会缓慢移动，直到它位于物体后面。
I made the camera position 10 units from an object, but not behind it. I dont want the camera position behind the object right away when it rotates, I want that when I will rotate the object, the camera position will move slowly until it will be behind the object.

查看 XNA App Hub 中的相机示例：http://create.msdn .com/en-US/education/catalog/sample/chasecamera
它基本上按照您所描述的方式进行：它是一个追踪相机，滞后于对象并使用“类似弹簧”的行为来跟踪它。
从概述来看：“船和摄像机的运动都受简单的物理原理控制。当船加速离开时，摄像机向后拉。当船转弯时，摄像机在转向中滞后，以显示船的部分侧面视图。当船停止移动时，摄像机逐渐滑回原位”

It basically does what you describe: it's a chase camera that lags behind the object and follows it using a "spring like" behavior.
From the overview: "The motion of both the ship and the camera are governed by simple physics. When the ship speeds away, the camera pulls back. When the ship turns, the camera lags behind in the turn to show a partial profile view of the ship. When the ship stops moving, the camera gradually slides back into place"
