Gathering information with sensors

An AI works by first taking in information about its surroundings. Then, that data is analyzed in order to choose an action, and finally, the chosen action is executed. As you can see, we cannot do anything without information, so let’s start with that part.

There are several sources of information our AI can use, such as data about itself (life and bullets) or maybe some game state (winning condition or remaining enemies), which can easily be found with the code we’ve seen so far. One important source of information, however, is also the AI senses. According to the needs of our game, we might need different senses such as sight and hearing, but in our case, sight will be enough, so let’s learn how to code that.

In this section, we will examine the following sensor concepts:

• Creating three-filter sensors with C#
• Creating three-filter sensors with Visual Scripting
• Debugging with gizmos
