Youtube - PATROL AI WITH UNITY AND C# - EASY TUTORIAL

This tutorial just sets up a basic patrolling AI where empty gameobject waypoints (called movespots in the tutorial) determine the enemy’s movement. It used an array of positions which contained all the possible waypoints, then randomly selected between them and moved the enemy there. This movement isn’t particularly useful for much, but it showcased a basic waypoint system well enough.

This tutorial actually attempted to correct the issue I brought up from the previous tutorials in my last blog where they were using if statements that ended when a position exactly equaled another position, which was very susceptible to math errors. They even used my quick (but still not great) work around of using distance and “less than” to set a small acceptable range to account for these small math errors.
