Explaintion of some AStar properties

Hello,

What's the purpose of following AStar properties? I don't understand what document said.

Surround Depth

Smooth Rotations

Strict Diagonals


An example model to present the use case will be nice.

FlexSim 23.1.1

Surround Depth

On model reset, the grid will resize itself to encompass all A* barriers with an unobstructed path around the edge of the area at least X cells wide (where X appears to be Surround Depth + 2). I guess this is make sure that you don't accidentally make some locations unreachable by placing barriers (?)

Smooth Rotations

When active, rotating to a new travel direction takes time, when inactive the rotation finishes instantly.


Strict Diagonals

From reading the tooltip I would think it is supposed to do the following:

A traveller can move between points A and B along the green path but not along the red path. If the option is active, it is also forbidden to travel along the diagonal line between the points. Though I wasn't able to actually observe a Task Executer doing so with the option deactivated.
