By: Brackeys

This tutorial shows how to setup the general AStar package in a 2D Unity project. It goes over the basics of setting up an initial grid and getting a basic enemy AI that will make the enemy follow a target. It also has an example to setup your own simple AStar enemy AI script using AStar's Pathfinding package.

This tutorial also cover the basics of setting up an enemy object with a graphics child object, flipping that graphic when the enemy should be going another direction, and just moving an enemy with physics and forces in general, instead of just updating position.

Sebastian Lague A* Tutorial Series - Path Smoothing - Pt. 08 and Pt. 09

December 13, 2019 A* Tutorial Series A* Pathfinding (E08: path smoothing 1/2) A* Pathfinding (E08: path smoothing 1/2) Link - Tutorial 1 By: Sebastian Lague A* Tutorial Series A* Pathfinding (E09: path smoothing 2/2) A* Pathfinding (E09: path smoothing 2/2) Link - Tutorial 2 By: Sebastian Lague A* Pathfinding (E08: path smoothing 1/2) Intro: These tutorials both covered the same general topic of smoothing the path of the unit. Theory Currently the units follow the path by making a straight line from one point to the next, which looks unnatural. To remedy this, they suggest a path smoothing technique. This system starts with each point having a small line pointing directly to the previous point, whose length is called the "turn distance". This line then has a perpendicular line emanating from the end, called the "turn boundary". Once the unit passes this turn boundary, it will start to turn towards the next point in the path (inste...
