当我在 ursina 中向播放器添加相机时，我的播放器正在下降并沿其 y 轴移动

Question

好的，在我的代码中，我试图让相机跟随我的播放器，并且我正在关注我在堆栈溢出中找到的教程。 但是当我这样做时，玩家“跌倒”并在其 y 轴上旋转这是怎么发生的，我也试图生成地面 class 但我不认为我这样做了。 并查看了 ursina 的所有文档并查看了如何制作视频，我仍然不明白为什么。 我做错了什么？

Answer 1

它正在下落，因为地面高于玩家的底部。 这可以通过向下移动地面来解决，例如 y=-1。 此外，像您一样将 origin_y 设置为负值将移动 model 并向上碰撞。

Answer 2

我想这会对你有所帮助。 您必须更改地面和玩家的y坐标：
