I have the free version. I need this package for wandering, patrolling, investigating (if noise heard, move to noise location) and perhaps some other things later. This is a topdown 2D unity game. Which components should I be familiar with, which properties of those components would I use the most? Is the grid type graph good for my game? The motor of my NPC will handle all navigation related methods.
For managing the individual graphs you’ll want to get familiar with AstarPath. And for your units you’ll want to read up on the Seeker which basically “finds the path” and the three Movement Scripts which apply and “walk along” that path.

This is the older getting started guide but it’s what was written for the free version. Give it a look to get started and definitely get back to us if you need any more help!
