android - 不知道如何用语言表达。我的应用程序在它应该将一个元素放在飞机上然后没有响应时出现故障

问题描述

链接到谷歌驱动器上的应用程序我在 gitHub 上有这个应用程序，但它与这个不完全相同，这就是为什么我在谷歌驱动器而不是 gitHub 上上传了这个版本

屏幕截图屏幕截图还包括问题摘要

新手在这里，这可能是一个简单的修复，但我只是还没有找到它。

我的屏幕底部有一个带有家具图片/图标的菜单。我希望当您单击其中一张图片并单击锚点（我可以放置对象/资产的地方）时，该对象应放置在您正在点击的锚点上

在点击锚点后，我尝试登录到调试控制台，以查看应用程序是否识别出已点击的资产/对象。

因此，例如，如果我点击椅子然后点击锚点，应用程序确实会识别出我点击了椅子。

我安装了sceneform插件我的gradle依赖项中有sceneform

对不起所有这些代码，只是不知道问题到底出在哪里。

我的猜测是它只在放置对象时出现，我想为可能需要查看缺失部分的任何人添加它

我希望当我单击家具物品的图片然后单击锚点时，该对象会出现在锚点上。相反，当我这样做时，应用程序会出现“故障”，然后我的水龙头没有得到任何响应
