Class FloodPathTracer Extends ABPath

Public

Traces a path created with the Pathfinding.FloodPath.

See Pathfinding.FloodPath for examples on how to use this path type

A* Pro Feature:

This is an A* Pathfinding Project Pro feature only. This function/class/variable might not exist in the Free version of the A* Pathfinding Project or the functionality might be limited.
