If [code]true[/code] a simplified version of the path will be returned with less critical path points removed. The simplification amount is controlled by [member simplify_epsilon]. The simplification uses a variant of Ramer-Douglas-Peucker algorithm for curve point decimation.
Path simplification can be helpful to mitigate various path following issues that can arise with certain agent types and script behaviors. E.g. "steering" agents or avoidance in "open fields".
