Function for Unity Engine

Run Python functions (a.k.a "predictors") locally in your Unity apps and games, with full GPU acceleration and zero dependencies.

Tip

Join our waitlist to bring your custom Python functions and run them on-device across Android, iOS, macOS, Linux, web, and Windows.

Installing Function

Add the following items to your Unity project's Packages/manifest.json:

{
  "scopedRegistries": [
    {
      "name": "Function",
      "url": "https://registry.npmjs.com",
      "scopes": ["ai.fxn"]
    }
  ],
  "dependencies": {
    "ai.fxn.fxn3d": "0.0.30"
  }
}

Retrieving your Access Key

Head over to fxn.ai to create an account by logging in. Once you do, generate an access key:

Then add it to your Unity project in Project Settings > Function:

Caution

If your Unity project is open-source, make sure to add UserSettings/ to your .gitignore file to keep your Function access key private.

Making a Prediction

First, create a Function client:

using Function;

// Create a Function client
var fxn = FunctionUnity.Create();

Then make a prediction:

// Make a prediction
var prediction = await fxn.Predictions.Create(
    tag: "@fxn/greeting",
    inputs: new () { ["name"] = "Roberta" }
);
// Log the result
Debug.Log(prediction.results[0]);
