wait - 让海龟等待 x 刻度数

Question

我正在尝试做的部分工作是让一种海龟四处移动，但是当一只海龟到达目的地时，海龟会等待一定数量的滴答声，然后再继续吗？也可以让海龟根据它们的目的地(不同的补丁颜色)等待不同数量的滴答声。是制作海龟品种或全局变量来计算滴答声的情况吗？希望相关的代码如下。

Answer 1

你是对的，这可以通过让海龟计算它们在一 block 补丁上的刻度数来完成。此外，这必须是海龟变量而不是全局变量，因为每只海龟对此都有不同的值

我使用的方法是这样的:

1. 一旦乌龟到达目的地，将ticks(记录到现在为止已通过的滴答数的全局变量)记录到乌龟变量中，比如ticks-since-here。这就像一个时间戳。

2. 在每个连续的滴答声中检查当前时间 ticks 全局变量和 ticks-since-here 海龟变量之间的差异。如果这变得大于允许乌龟停留在补丁上的刻度数，让它选择并移动到新的目的地。
