让海龟等待x滴答声 [英] Making turtles wait x number of ticks

问题描述

我要做的部分工作是让一只乌龟到处走动，但是当一只乌龟到达目的地时，乌龟要等待一定的滴答声才能继续?也有可能使海龟根据其目的地(不同的斑块颜色)等待不同数量的of.是制作海龟品种或全局变量来计算of的数量吗?希望相关的代码如下.

Part of what I am trying to do is make a breed of turtles move around, but when one reaches its destination that turtle waits for a certain number of ticks before continuing ? Also is it possible to make turtles wait for different number of ticks depending upon their destination ( different patch colors). Is it a case of making a turtle breed or global variable to count the number of ticks? The hopefully relevant code is below.

推荐答案

您是对的，可以通过让海龟计算它们在补丁上的s虫数量来实现.另外，这必须是乌龟变量，而不是全局变量，因为每只乌龟对此都有不同的值

You are right, this can be done by making the turtles count the number of ticks they have been on a patch. Also this has to be a turtle variable and not a global variable since each turtle will have a different value for this

我使用的方法是:

1. 乌龟到达目的地后，将ticks(记录到现在为止已经过去的滴答声数量的全局变量)记录到乌龟变量中，例如ticks-since-here.这就像时间戳一样.

2. 在每个连续的刻度上，检查当前时间ticks全局变量和ticks-since-here turtle变量之间的差.如果该数量大于允许乌龟停留在补丁上的滴答声的数量，请让它选择并移动到新的目的地.

1. Once the turtle arrives at its destination record the ticks (the global variable which records the number of ticks that have passed till now) into a turtle variable say ticks-since-here. This works like a time-stamp.

2. On each successive tick check the difference between the current-time ticks global variable and the ticks-since-here turtle variable. If this becomes greater than the number of ticks the turtle is allowed to stay on the patch, let it choose and move to the new destination.
