在Unity中暂停Google ARCore [英] Pause Google ARCore in Unity

问题描述

是否可以暂停或至少停止ARCore旋转屏幕.我有一个菜单，可以通过销毁游戏对象并实例化它来在AR场景之间切换"，但是当我重新激活菜单时，SessionComponent继续控制摄像头，因为它仍在跟踪剩余的锚点.我不知道如何删除锚，因为它是通过调用Session.CreateAnchor创建的，而Session似乎没有删除锚的方法.我假设删除锚点可能是阻止ARCore跟踪的最佳方法，并且类似于重置它，但是我无法找到如何删除锚点的方法.我实际上尝试删除了Anchor，但是它似乎仍保留在列表中，或者似乎仍然有某些东西试图在Session和Anchor类中跟踪它，从而导致nullptr异常.

Is there any way to pause, or at least stop ARCore from rotating the screen. I have a menu that I use to "switch" between AR scenes by destroying the gameobject and instantiating it, but when I reactivate the menu the SessionComponent continues to control the camera because it is still tracking the leftover anchor. I have no idea how to delete the anchor because of the fact that it is created by calling Session.CreateAnchor and Session doesn't seem to have a method for removing anchors. I'm assuming that removing the anchor could be the best way to stop ARCore from tracking and would be similar to resetting it, but I can't find out how to remove the Anchor. I tried actually deleting the Anchor, but it seems to be still kept in a list or there seems to be something that still attempt to track it in the Session and Anchor class that causes a nullptr exception.

推荐答案

使用ARCoreSession.Destroy(yourAnchor)，如果不起作用，请使用ARCoreSession.DestroyImmediate(yourAnchor).

Use ARCoreSession.Destroy(yourAnchor), if this doesn't work use ARCoreSession.DestroyImmediate(yourAnchor).

它在官方文档中仍然没有更新.但是，这就是您实现它的方式

It is still not updated in the official documentation. But, this is how you achieve it
