0 Welcome to sensors. 1

In order for an AI to take actions, it needs to do two things. 2

First, to understand its environment. 3

We discussed this in the previous chapters and also to sense its surroundings. 4

That means enemies, useful items, useful locations, and much more. 5

These sensors can be taken from real life and then implemented, for example, sight, hearing, touching, 6

for example, if the AI gets hit by a player's bullet. 7

In this module we will be discussing about sight and hit. 8

And in the sight sensors we actually have three different categories. 9

We have the range, which takes all the stuff around it. 10

The Field of View Cone, which is basically what's in front of the eyes of the enemy, and also a raycast 11

which checks if the object that should be visible 12

is not occluded by a box, for example, or some obstacle that is between the AI agent and that object. 13

Let's look now at each of these sensors and see how they are implemented.
