How to get the "Stop for Turns" count in A* Navigator

I can set "Stop for Turns" in A* Navigator.

Is there a way to know how many times this "Stop for Turns" has been done?

Software Version:

FlexSim 21.2.4

a star navigation stop for turns

Here is one idea how this could be done:

I an instanced process flow with the task executer as instance object, I listen to the "OnAStarNavigatePath" event. This happens when the task executer starts traveling and let's you assign the node with the kinematics info to a label on the token.

I then use the "getkinematics()" command (see link below) to search the kinematics for rotations and store their start times in an array. The token then waits for the start time of the first rotate kinematic and increments a label on the task executer. It then loops around until there are no more entries in the array (no more rotations in the travel path).

I also write the current token to a label on the task executer. When it becomes blocked as has to take a new path, this allows me to prematurely release the counting token from the loop so only the rotations that actually happen are counted.

@Felix Möhlmann ,

Sorry for the late reply.

This is exactly what I wanted to do!

Thank you for your answer.
