+A navigation link does not provide any specialized movement through the link. Instead, when
+an agent reaches the position of a link, game code needs to react (e.g. through area triggers)
+and provide means for the agent to move through the link to end up at the links other position
+(e.g. through teleport or animation). Without that an agent will attempt to move itself along
+the path of the link. You could end up with an agent walking over a bottomless pit instead of
+waiting for a moving platform, or walking through a teleporter and proceeding through a wall.
