Firstly, please do not use an existing thread, create a new one.

Im getting a crash while running on ipad, im using unity 4 and vuforia 1.5.8.

We do not support older versions of Vuforia so you need to upgrade to the latest.

I cant understand what has happend or is wrong. I created the new dataset using the Target Manger web.

The Target Manager has been updated and no longer works on older versions of Vuforia.

Hi, please excuse my english, ill try and explain my problem as best as i can.

Im getting a crash while running on ipad, im using unity 4 and vuforia 1.5.8.

I have the ImageTarget object and Unity's AR camera dataset activated and loaded and setup (in the inspector, under Data Set Load Behaviour).

When i try using other datasets it works perfectly and i have hade other custom datasets working before, now they don't work after reimporting them anymore.

The last log in Xcode before the crash is "Successfully created data set".

I cant understand what has happend or is wrong. I created the new dataset using the Target Manger web.

Any help would be much apriciated!

I also googled but couldn't find that how to replace in right way

A better strategy would be to search the sample code in MonoDevelop for example uses of the API.

e.g. If you look at ImageTargetsMenu.cs you'll find the code below.

        ImageTracker imageTracker = (ImageTracker)TrackerManager.Instance.GetTracker(Tracker.Type.IMAGE_TRACKER);

        IEnumerable<DataSet> dataSets = imageTracker.GetDataSets();

        IEnumerable<DataSet> activeDataSets = imageTracker.GetActiveDataSets();

        // Changes current active dataset

        if (dataSets.Count() >= 2 && activeDataSets.Count() >= 1)

        {

             DataSet activeDataSet = activeDataSets.ElementAt(0);

             if(mCurrentDataSetIndex == 0)

             {

                 imageTracker.DeactivateDataSet(activeDataSet);

                 imageTracker.ActivateDataSet(dataSets.ElementAt(1));

                 mCurrentDataSetIndex = 1;

                 mDatasetText = SWITCH_TO_STONES_AND_CHIPS;

             }else

             {

                 imageTracker.DeactivateDataSet(activeDataSet);

                 imageTracker.ActivateDataSet(dataSets.ElementAt(0));

                 mCurrentDataSetIndex = 0;

                 mDatasetText = SWITCH_TO_TARMAC_TEXT;

             }

         }

Thanks Nalin,

Thank you Nalin for posting this migration 1.5 to 2.x at here "https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/migrating-your-unity-project-vuforia-15-2x". Sorry it is not proper mentioned that how to replace code properly, On 5th point, I just replace code "ImageTracker.GetDataSets()" instead of "GetNumDataSets() and GetDataSet(int)" but it generating many issues. I also googled but couldn't find that how to replace in right way, can you please help me on that, how to replace lines of code in right way?

Thanks

Please see the new sticky at the top that contains the Migration guide from 1.5 to 2.x

Thanks Nalin,

I just tried to upgrade 1.5 to 2.6 but it generate many errors which I don't think so I can hanlde without any guide. So I think I need link where I can first upgrade 1.5 to 2.0 which is currently not available or hide and then 2.0 to 2.6 which already given "https://developer.vuforia.com/resources/dev-guide/migrating-your-unity-project". So kindly show us or open for us link 1.5 to 2.0. I need to do this ASAP, this will be great for me if you can. Thanks in advance.

Sorry about the OWA link - not sure where or how it happened?

There used to be a 1.5 to 2.0 migration guide but that has currently disappeared from the portal and I am trying to see if we can get it restored.

In the meantime there is another migration guide from 2.0 to 2.5/2.6, but I am not sure this helps you.

Thanks Nalin,

I just open the link in post which you mentioned link in reply "https://developer.vuforia.com/resources/dev-guide/transitionmigration-guide" it open Outlook Web App page, see attached file, need your assistance at here. I googled and found this migration link "https://developer.vuforia.com/resources/dev-guide/migrating-your-unity-project". So am I eligible to follow this link because I dont know what is the least version required at here for Vuforia SDK like 1.5 to 2.6 or 2.0 to 2.6. Now I am at 1.5 so am I eligible to upgrade to 2.6 or I need other link to upgrade to 2.6? Thanks again.

Please see this thread for more details:

If you are genenerating new datasets for applications on 1.5.8 they will not be compatible, so you have no choice but to upgraed your application to the latest SDK.

While you are at it you might wish to consider upgrading to a later Unity version as well.
