How To Make Ai In Unity 2D

Greetings readers!
Welcome, readers!

In this article, we will discuss how to create artificial intelligence (AI) for your game in Unity 2D. We will cover the basics of AI programming and provide step-by-step instructions on how to implement it in your game.

Understanding AI

Before we begin, it’s important to understand what AI is and why it’s useful in games. AI refers to the ability of a computer program to make decisions and perform tasks that are typically associated with human intelligence.

In the context of game development, AI can be used to control non-player characters (NPCs) or enemies in your game. By implementing AI, you can create more engaging and challenging gameplay experiences for your players.

Implementing AI in Unity 2D

Now that we have a basic understanding of AI, let’s dive into the process of implementing it in Unity 2D. Here are the steps you can follow:

  1. Create an AI script: Start by creating a new C# script and name it “AIController”. This script will be responsible for controlling your NPCs or enemies.
  2. Define variables: In the AIController script, define some variables that will be used to control your NPC’s behavior. For example, you can create variables for speed, acceleration, and target distance.
  3. Implement the Update() function: The Update() function is called every frame in Unity. Use this function to update your NPC’s position and movement based on the values of the variables you defined earlier.
  4. Create a Patrol Area: To make your NPC move around, create a patrol area using Unity’s built-in NavMesh system. This will allow your NPC to navigate through your game world and avoid obstacles.
  5. Attacking the Player: If you want your NPC to attack the player, implement a function that checks if the player is within range of the NPC’s weapon. If so, call a function to fire the weapon at the player.


In conclusion, creating AI in Unity 2D can greatly enhance your gameplay experience. By following the steps outlined in this article, you can implement AI for your NPCs or enemies and create more engaging and challenging gameplay experiences for your players.
