我的问题是您可以看到插值占 20 个点，但是当它运行时它只运行其中的一半，然后又回到开头。我不明白为什么它会在第 10 个间隔停止。我知道我错过了什么，但是什么？

顺便说一句，我是新来的，所以你看到我可以修复的任何东西，请继续让我知道。

提前致谢。

fraction_changed输出介于 0 和 1 之间的值。PositionInterpolator 的键具有从 0 到 20 的整数值。这意味着每当 TimeSensor 开始/结束时，只有第一个 (0) 和第二个 (1) 值将处于活动状态。基本上，您的转换将交替转换为 (0,0,0) 5 次和 (10, 0, 0) 5 次。

要实现您想要的，您必须将键数组更改为：key [0 0.05 0.10 0.15 .... 0.95 1]

或将person-time.time路由到 person-position.set_fraction。这将遍历所有键值一次。

它应该以这种方式工作。
