Here is my guess: On Calculate Path is an event, that fires when a Taskexecuter starts or change his travel to a destination cell. In Version 20.0 you have only access to events directly of a Taskexecuter. OnReceiveTasksequence, On Start Task and some more. Since you have not access to more events of an AStar Grid you correlate any change of an older travelpath to another newer travelpath of a Traveler to imitate On Calculate Path event. You can do this on intervals of allocating and deallocating of grid cells or just time ticks.

Jörg is right. But the reason the onCalculatePath is being used in the Kiva model in this way is to return the list of barriers that are in play depending on whether the robot is loaded or empty. The dynamic barriers are not in earlier versions so you should upgrade if you can.

我可以使用自定義代碼來修改它的程序，以便在 2020 版本中使用該代碼嗎？

The short answer is 'probably not'.
