How to setup User Defined Target in Unity 2017.2

Hi all
I want to have User Defined Target setup in Unity 2017.2 but I dont know how.
This guide https://library.vuforia.com/articles/Training/User-Defined-Targets-Guide
uses some prefab that I can't seem to find anywhere.
There is component User Definder Target Buiding Behavior but it is not enough to make it run.
Is there some good guide that can show step by step use of Vuforia User Target system on new Unity with integrated Vuforia support?

 

Hello @denmla1000

I apologize for the outdated documentation, our team is aware of it and is working towards an update to it.

In the meantime, our Core Samples (available on the Unity Asset Store for free) have a scene demonstrating how to set up User Defined Targets.

In short, you'll need to create an Image Target and then set the "Type" field to 'User Defined.' Then create a new object and add the "User Defined Target Builder" behaviour and "UDT Event Handler" script to this new object.

Please check out the samples and let me know if you have any further questions.

Apologies again for the inconvenience.

 

I did all the same as in core samples, but still it doesn't work.

 

Can you provide more information on what doesn't work and what issues you are running into?

 

User Defined Tracking is just bad documented, it's not updated, in current version of Unity UDT is different from YouTube tutorials, and your documentation is also different. I tried to do the same thing as you did in Core Sample, but still not working, as I am missing something and I can't find any documentation either.

 

Hi to all, actually I did make a demo out of the UDT scene of the above mentioned sample. The only problem is that you always need the sample project since there are things missing from the core package. I have Unity 2017.3p4 installed with Vuforia 7.0.47 integration. The integrated Unity package does not have the "UDT Event Handler" script. I suppose that is up to the developer to create one each time he needs different behavior?

 

Hello,
In the Vuforia Sample package, you can open Sample Resources/Scenes/UserDefinedTargets.unity
Note: the game object named QualityMeter, which is include Frame-Quality-Meter script => it will fix Null Exception in UDT-Event-Handler script when you play the scene.
In your project, you have to create a game object like that. (I don't know what does it use for because there's no document right now)

Hi,
it would be nice to get that UDTEventHandler.cs Script for User- defined target builder. I looked in WWW, but found nothing. Coule anyone tell me where to find it?

 

There's Vuforia Sample app on the Unity Asset Store, download it and look at how vuforia developers did it, you will also find necessary scripts.

 

Hello @tomicz,

thanks for your quick answer
i've already downloaded Vuforia-Core-Samples, but the C#- Script "UDTEventHandler.cs" is missing. Do you mean that with the Vuforia Sample App?

 

@tomicz
thanks! had an older version of "vuforia-core-samples". I downloaded the new package and that important UDTEventHandler.cs is included. Thanks a lot, you saved my day Have a nice day!
