# Detection Parameters

A detection type is how the enemy will notice the players. You can set different types or all together.

Each detection type has the **Detection** **Sensitivity** value - it means how quickly opponents will notice the characters.

### Vision

The vision is divided into 2 parts - <mark style="color:green;">**central vision**</mark> and <mark style="color:orange;">**peripheral**</mark>. During the game, if a player is in sight, the enemy will see him. And depending on the **AI behavior**, the enemy will immediately attack the player or start looking for him.

Here you'll find more info about the **AI behavior**:

### Hearing

All characters have a noise radius, if the enemy is in that area and there are no walls between them, then he hears the character.
