Hey Unity devs!π
Let us explore how to integrate OpenAI with Unity today with two powerful scripts from this amazing github repository. Big props to the creative minds behind it! π
TextToSpeech Scriptπ£οΈ:
Have you ever wanted to convert text to speech without any effort? The TextToSpeech script can do just that! It uses OpenAI's magic to transform your text into a masterwork of audio. Here's a little sample of what it can achieve:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
using System.Text;
using System.IO;
public class TextToSpeech : MonoBehaviour
{
private string apiKey = "YOUR_API_KEY";
private string baseUrl = "https://api.openai.com/v1/audio/speech";
private string model = "tts-1";
private string voice = "alloy";
private string inputText = "Hello World, This is a test to see the TTS of OpenAI!";
private string audioFileName = "speech.mp3";
private void Start()
{
StartCoroutine(GenerateSpeech());
}
private IEnumerator GenerateSpeech()
{
var payload = new
{
model = model,
voice = voice,
input = inputText
};
// Convert the payload to a JSON string.
string jsonPayload = JsonUtility.ToJson(payload);
using (UnityWebRequest www = new UnityWebRequest(baseUrl, "POST"))
{
www.uploadHandler = new UploadHandlerRaw(Encoding.UTF8.GetBytes(jsonPayload));
www.downloadHandler = new DownloadHandlerBuffer();
www.SetRequestHeader("Authorization", "Bearer " + apiKey);
www.SetRequestHeader("Content-Type", "application/json");
yield return www.SendWebRequest();
if (www.result == UnityWebRequest.Result.Success)
{
// Saving the audio data as an MP3 file.
File.WriteAllBytes(audioFileName, www.downloadHandler.data);
Debug.Log("Audio file saved as: " + audioFileName);
}
else
{
Debug.LogError("Failed to generate speech: " + www.error);
}
}
}
}
Just enter in your text, hit play, and voila! Your text is now a melody. π
OpenAI Vision Script πΈ:
Let us move on to discuss the AI Vision script, a script that lets you use OpenAI's GPT-4 Vision model to intelligently query images. Notice how simple it is:
using System.Collections;
using System.Collections.Generic;
using [System.IO](http://system.io/);
using UnityEngine;
using UnityEngine.Networking;
public class AIVision : MonoBehaviour
{
[SerializeField] private string openAIUrl = "https://api.openai.com/v1/chat/completions";
[SerializeField] private string apiKey = "YOUR_API_KEY";
public string[] imageUrls;
public string queryMessage = "What are in these images? Is there any difference between them?";
void Start()
{
if (imageUrls.Length > 0)
{
StartCoroutine(PostImageQueryRequest(imageUrls));
}
}
public void OnClickSend()
{
StartCoroutine(PostImageQueryRequest(imageUrls));
}
IEnumerator PostImageQueryRequest(string[] urls)
{
var requestBody = new
{
model = "gpt-4-vision-preview",
messages = BuildImageQueryMessages(urls),
max_tokens = 300
};
string json = JsonUtility.ToJson(requestBody);
using (UnityWebRequest webRequest = UnityWebRequest.Post(openAIUrl, "POST"))
{
byte[] jsonToSend = new System.Text.UTF8Encoding().GetBytes(json);
webRequest.uploadHandler = new UploadHandlerRaw(jsonToSend);
webRequest.uploadHandler.contentType = "application/json";
webRequest.downloadHandler = new DownloadHandlerBuffer();
webRequest.SetRequestHeader("Content-Type", "application/json");
webRequest.SetRequestHeader("Authorization", "Bearer " + apiKey);
yield return webRequest.SendWebRequest();
if (webRequest.result != UnityWebRequest.Result.Success)
{
Debug.LogError("Error: " + webRequest.error);
}
else
{
Debug.Log("Response: " + webRequest.downloadHandler.text);
}
}
}
private object[] BuildImageQueryMessages(string[] urls)
{
var messages = new List<object>
{
new { type = "text", text = queryMessage }
};
foreach (var url in urls)
{
messages.Add(new { type = "image_url", image_url = url });
}
return messages.ToArray();
}
public void LoadImagesFromFile(string filePath)
{
if (!File.Exists(filePath))
{
Debug.LogError("File not found: " + filePath);
return;
}
try
{
string[] lines = File.ReadAllLines(filePath);
StartCoroutine(PostImageQueryRequest(lines));
}
catch (IOException e)
{
Debug.LogError("Error reading the file: " + e.Message);
}
}
}
With just a snippet of code, you're equipped to query images and receive insightful responses. How cool is that? π
How to Get Started:
- - API Key: Grab your OpenAI API key.
- - Integration: Copy these scripts into your Unity project.
- - Customisation: Tweak parameters to fit your needs.
- - Run: Hit play and enjoy!
Feel free to explore the full capabilities, and don't forget to give a shoutout to the creators of this repository!

Hi, I use your code.
then Error: HTTP/1.1 400 Bad Request occured.
Do you know how to solve this error?
I didn't edit your code except adding imageurl and apikey
