So, there are two main classes: one being the “media handler” and the other one being the “api handler”.

Info:

- One script handles the API: sends user text/audio to Convai, receives the AI’s response, plays the voice audio if included.
- The other one intercepts the AI’s response text, looks for patterns like “video of…” or other language variants, and uses fuzzy matching to find the closest local video listed in a`videoList.txt` file (containing the video file names, and I know, it’s not very dynamic).
- If a match is found, it shows the video UI and plays the corresponding video from the local folder.
- Video titles are loaded asynchronously from `videoList.txt` in `StreamingAssets/Videos`, making it easy to update the list without recompiling.
- For fuzzy matching, I used **FuzzySharp** (NuGet package) to compare the requested video name with available titles and trigger playback when the match confidence exceeds a threshold (I set it at 30%).
- I handle platform differences by copying the video to `Application.persistentDataPath` before playing it, which is especially needed on Android where direct access to `StreamingAssets` isn’t possible.
- Commands work across multiple languages by checking for keywords like:
- “video of” (English)
- “video di” (Italian)
- “vidéo de” (French)
- etc.
- Example workflow:

1. User says: _“I’d like to see the video of -insert video title here-.”_
2. Convai responds: _“Here is the video of -insert video title here-.”_
3. The media handler parses “video of -insert video title here-”, matches it to the closest video, and plays it automatically.

Here are the links to the 2 classes:

> **[ConvaiAPIHandler — Codefile](https://codefile.io/f/MRVOanbQaT)**
>
> Create collaborative code files online for your technical interviews, pair programming, teaching, etc.

> **[ConvaiMediaHandler — Codefile](https://codefile.io/f/saIOcJyWWO)**
>
> Create collaborative code files online for your technical interviews, pair programming, teaching, etc.

The ConvaiAPIHandler is attached to an empty game object, while the ConvaiMediaHandler is attached directly to the canvas of the video player.

If you have any questions please ask.
