How it works...
The major benefit of using NavMeshes is that they can provide for more natural movements.
Furthermore, they allow for pathfinding if our bot cannot find a direct route to its target. This is
particularly useful for areas where there are a large number of narrow walls, such as a maze.
If our pawn can't find a direct route to its target, whether it is a vector when we are using
the MoveTo() function or actor when we use the MoveToward() function, pathfinding can
automatically generate an efficient route.
By setting a list of constraints, such as avoiding edges of walls or finding a random target,
we can create natural movements and prevent our pawn from getting stuck. Along the way
we have our pawn create a list of points it needs to reach before it can arrive at our target,
in addition to displaying a red sphere at its next destination for debugging purposes.
