However, the method 'RegisterTrackableEventHandler' from the interface 'ITrackableEventHandler' are outdated and do not work as they should anymore. So I found a guide (see below) which seems to work for the most parts. Scripts // NetworkingManager.My goal is to create a marker content dynamically from an assigned prefab when a marker is tracked.

In Part 2, weвЂ™ll look at downloading 3D model files using the DownloadHandlerFile, how to cache them locally to speed up subsequent downloads, and how to load them into Unity at run time.

These are just some of the helper classes, check out the Unity docs for a lot more. In conclusion, UnityWebRequest gives us a lot of options when downloading files and data from the internet. Then drag the NetworkManager GameObject into the NetworkManager.cs scriptвЂ™s audioSource reference. Lastly, click on your NetworkManager and add an AudioSource component.

Duplicate a button, rename it and change the text to вЂњDownload Sound.вЂќ Update the click function to be вЂњDownloadSoundвЂќ and enter a sample URL for an ogg file that you can download. Follow the same process as for the image.

Configuring the SceneДЇinally, letвЂ™s jump into our scene and configure it to download and play our sound.

We chose it because Windows doesnвЂ™t readily support the MPEG option, or mp3. AudioType.OGGVORBIS is just one of many you can try. YouвЂ™ll notice the subtle differences with helper classes, but itвЂ™s very similar to loading images! One thing to note, we need to specify the type of audio file to the GetAudioClip method. Using (UnityWebRequest req = UnityWebRequestMultimedia.GetAudioClip(url, AudioType.OGGVORBIS)) If you're on a mac, you can try MPEG (mp3) Note, we try to download an OGGVORBIS (ogg) file because Windows doesn't support IEnumerator SoundRequest(string url, Action callback) Load the clip into our audio source and play Get the sound out using a helper classДЄudioClip clip = DownloadHandlerAudioClip.GetContent(req) If (req.isNetworkError || req.isHttpError)Дebug.Log($'') StartCoroutine(GetRequest('', (UnityWebRequest req) => This method doesnвЂ™t seem to do much, however, it letвЂ™s us flexibly make GET requests and pass the response from the server to a callback that we can process in other functions. Send the request and wait for a response Using (UnityWebRequest request = UnityWebRequest.Get(url)) IEnumerator GetRequest(string url, Action callback)

Public class NetworkManager : MonoBehaviour This might look different than what youвЂ™re used to, but IвЂ™ll explain why we use this approach. Once you open it up, weвЂ™re going to add a simple GetRequest method. WeвЂ™ll come back to this script during the tutorial to add more request types. Coding a GET UnityWebRequestДЇirstly, create a new C# script and name it NetworkManager.cs. Next, letвЂ™s dig into our coding out the network request.

The reason we added the Horizontal Layout Group is so that we can easily add more buttons in a row when we need to make more requests. Drag your Button under your Button Row and it should position itself in the top left of the screen. Hold down shift + alt and click top left to anchor your Button Row to the top left of the UI. Next, on your Button RowвЂ™s Rect Transform, click the Anchor Presets box. Search for вЂњHorizontal Layout GroupвЂќ and add it to your Button Row. Select it and then hit Add Component in the inspector. Add an empty GameObject under your Canvas named вЂњButton RowвЂќ. This will create a Canvas element holding your button.

Open a fresh project and select the Game tab to preview our UI. To start, letвЂ™s set up our scene in Unity. If not, there are a lot of great resources available. For brevity, we assume that you are familiar with web servers and making HTTP requests. Using UnityWebRequest.GetДЇirstly, weвЂ™ll cover a simple example of how to request data from a web server. If youвЂ™re coming from the video you can find the NetworkingManager.cs script in the scripts section below. But to do this, we need to know how to interact with web servers. We can enable features like leader boards, user logins, and cloud data backups. Using this data allows us to take our games and apps to the next level. Nowadays in app development, more data is coming from websites and APIs. In this post, weвЂ™ll cover different ways that we can make network requests using UnityвЂ™s UnityWebRequest class. вЂњLearn how to efficiently use the UnityWebRequest class to download many different resources from the web.вЂќ Overview
