Can anyone tell me how to retrieve the metadata string in Unity using C#.

Yes. The easiest approach will probably be to pass the metadata to your script by referencing it using GetComponent() in the event handler. Otherwise rewriting the event handler in Javascript would require you to restructure the project to ensure the proper compilation order for the C# references.

See: http://docs.unity3d.com/Documentation/Manual/Scripting42.html

Like I said below:


gives you the metadata

If you output this using Debug.Log for the sample it should show something like samplebook1.json which is the content of the metadata file pertaining to that target.

Adding string is not the problem.

The problem is how to grab the string from the metadata and store it in a string variable.

It seems you need to figure out how to add strings in c#

A simple web search of  "unity3d add string c#" reveals the following:

Thanks NalinS,

I have a string variable called url_path, I want to change it to : url_path = "My url"+"metadata string";

How can I do it.

Check the source and you will find references to metadata in the callback below.




    /// <summary>

    /// Handles new search results

    /// </summary>

    /// <param name="targetSearchResult"></param>

    public void OnNewSearchResult(TargetFinder.TargetSearchResult targetSearchResult)


        // This code demonstrates how to reuse an ImageTargetBehaviour for new search results and modifying it according to the metadata

        // Depending on your application, it can make more sense to duplicate the ImageTargetBehaviour using Instantiate(), 

        // or to create a new ImageTargetBehaviour for each new result


        // Vuforia will return a new object with the right script automatically if you use

        // TargetFinder.EnableTracking(TargetSearchResult result, string gameObjectName)


        //Check if the metadata isn't null

        if(targetSearchResult.MetaData == null)





        // enable the new result with the same ImageTargetBehaviour:

        ImageTargetBehaviour imageTargetBehaviour = mImageTracker.TargetFinder.EnableTracking(targetSearchResult, mParentOfImageTargetTemplate);


        if (imageTargetBehaviour != null)


            // stop the target finder

            mCloudRecoBehaviour.CloudRecoEnabled = false;


            // Calls the TargetCreated Method of the SceneManager object to start loading

            // the BookData from the JSON
