In crowd animation, the Path Follow behavior lets you direct delegates to traverse a specified path during a crowd simulation. Delegates can move forward or backward along paths, and when they reach the end, they can loop back to the start or reverse direction, or even continue in the same general direction.
If the delegate's start position isn't on the path at the start of the simulation, it moves to the path before following the path. During the solution, character studio intermittently displays an optional target icon to show the delegate's immediate goal; this changes as the simulation proceeds.
