How To Develop A Game in Unity Using ChatGPT?

Unity is the world’s most leading Game Development Engine that allows you to create, manage and monetize games on different platforms. You only need to develop the game once and it can be deployed on every gaming platform. These platforms include Windows, Android, iOS, Oculus, and PlayStation. It is also used in Automotive, Transportation & Manufacturing, Film, Animation & Cinematics, Architecture, Engineering & Construction, and Sales & Marketing. Everything you can imagine, unity can make it possible.

In this tutorial, we’ll be using ChatGPT, a natural language processing tool developed by OpenAI, to help us develop a game in Unity.

  • Click the “Download” button next to “Unity Hub”.
  • Once the download is complete, run the installer to install Unity Hub on your machine.
  • Follow the prompts in the installer to complete the installation process.
  • Once Unity Hub is installed, open it and click the “Installs” tab.
  • Click the “Add” button and select the version of Unity you want to install.
  • Click the “Install” button to begin the installation process.
  • Follow the prompts in the installer to complete the installation process.

How To Develop A Game in Unity Using ChatGPT?

Creating a game in Unity can be a complex and time-consuming process, but it doesn’t have to be. Before you can start using ChatGPT, you’ll need to set up Unity on your machine. If you haven’t already done so, download Unity from the official website and follow the instructions to install it. Once it’s installed, open Unity and create a new project by clicking “New” in the top right corner of the start window.

After you have opened a new project, open ChatGPT on chrome. Install the necessary assets that will be required in your game depending on the kind of game you are developing.

You can use ChatGPT to generate scripts for your game. However, ChatGPT can’t really develop the whole game for you in Unity but it’s a helpful tool in generating scripts for your characters and other elements in the game. For example, we asked ChatGPT to generate a script of a character controller that can walk, run and jump. Here are the results:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CharacterController : MonoBehaviour
{
public float speed = 5f;
public float runMultiplier = 2f;
public float jumpForce = 10f;
private Rigidbody2D rb;
private bool isGrounded = true;

void Start()
{
    rb = GetComponent<Rigidbody2D>();
}

void Update()
{
    float horizontalInput = Input.GetAxis("Horizontal");
    bool isRunning = Input.GetKey(KeyCode.LeftShift);
    float currentSpeed = speed;
    if (isRunning)
    {
        currentSpeed *= runMultiplier;
    }

    rb.velocity = new Vector2(horizontalInput * currentSpeed, rb.velocity.y);

    if (Input.GetKeyDown(KeyCode.Space) && isGrounded)
    {
        rb.AddForce(Vector2.up * jumpForce, ForceMode2D.Impulse);
        isGrounded = false;
    }
}

void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.gameObject.tag == "Ground")
    {
        isGrounded = true;
    }
}
}

The code above is for a 2d character that can walk, run and jump using this script. Let’s try asking it for another script “Generate a script for an endless runner character”.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EndlessRunnerCharacter : MonoBehaviour
{
public float speed = 5f;
public float jumpForce = 10f;
private Rigidbody2D rb;
private bool isGrounded = true;

void Start()
{
rb = GetComponent();
}

void Update()
{
rb.velocity = new Vector2(speed, rb.velocity.y);
if (Input.GetKeyDown(KeyCode.Space) && isGrounded)
{
    rb.AddForce(Vector2.up * jumpForce, ForceMode2D.Impulse);
    isGrounded = false;
}
}

void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject.tag == "Ground")
{
isGrounded = true;
}
}

With the help of ChatGPT, all you need to do is frontend work, like import the assets and ask ChatGPT to write scripts for you.

Final Words

ChatGPT is a great tool, it can help a lot in developing a game in Unity. However, ChatGPT is still under development and is still learning (training). So, there is a chance it will sometimes generate a script that won’t run or have errors. Before trying to develop a game in unity using ChatGPT, make sure you have enough knowledge to differentiate between a working script and a non-working script.
