how to get NPC to FOLLOW YOU in terraria?

Answer 1

There really isn't a way to lead NPCs in terraria, however, they can only jump small distances so be sure to make small stairs for them. Also you can "force" them to go somewhere by blocking of the previous route of stairs. furthermore if you build a suitable house for them they will eventually move in on their own, which makes it easier to move NPCs found in mines.

Hope this helps
