All language subtitles for 1. Sensing the Game World

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.
