Question

空间中的玩家和用户立方体：

我想为我目前正在从事的项目寻求想法和帮助。

在此项目中，用户利用鼠标移动立方体（称为用户）以跟踪球体（称为播放器）的随机运动。有20个随机动作。当用户移动多维数据集时，它只能在x-y平面或x-z平面上移动，并且通过使用Shift键可以切换模式。然后，每3秒显示20个球体运动坐标和立方体（用户）坐标。

尽管具有此功能，但该程序无法正常运行。操纵立方体非常困难。有时，换档压力机无法很好地套准，因此很难在x-y平面上移动到x-z平面上。这不是最佳的用户体验。如果多维数据集不可见，则几乎不可能将其取回。另外，我很难弄清楚如何在盒子环境中绑定立方体和球体。

我希望我将来可以在Windows机器上针对Oculus Rift进行调整（我在MacBook Pro上运行），但是截至目前，我只是在尝试完成此原型合理的用户功能。

任何建议或帮助将不胜感激。

下面包含的是我GitHub上整个项目的链接，以及我项目的主要代码。

谢谢你，节日快乐！
