The ImageTargetBuilder has been moved to a precompiled DLL in 2.8. 

But its public API is still available and unchanged; you can find it here:


The UserDefinedTargetEventHandler is in the sample code of User Defined Target sample.

The sample illustrates how to use the prefabs and API to setup a UDT target.

Hi @hoseinAR2021

The script will not work on newer versions of Vuforia Engine.

Could you please elaborate on your use-case? We can then guide you on the features.

For example, I believe something similar to the ImageTargetBuilder is a new feature called Insta Image Targets which lets you create Image Targets at run-time. More info here: https://library.vuforia.com/articles/Solution/how-to-create-and-load-targets-in-unity.html

Also a good source on how-to are our Unity samples available here:https://assetstore.unity.com/publishers/24484 starting with the Core sample: https://assetstore.unity.com/packages/templates/packs/vuforia-core-samples-99026

Thank you.
