`Vuforia.ObjectTracker' does not contain a definition for `GetTargetFinder'

September 27, 2018 - 11:45am #1

Vuforia SDK Version: 7.5.20:d405d5a4b40800cf712d8239b7a320b7 -

Description with steps to reproduce: 1. Install Unity 2018.2.10f1

2. Enable Vuforia in XR settings

3. Enable VR support and put Vuforia SDK at top of list

4. Imported VR+AR asset package from Unity store

I get this error:

Assets/Common/Scripts/CloudRecoEventHandler.cs(82,42): error CS1061: Type `Vuforia.ObjectTracker' does not contain a definition for `GetTargetFinder' and no extension method `GetTargetFinder' of type `Vuforia.ObjectTracker' could be found. Are you missing an assembly reference?



Development OS (Mac OS X, Windows, Linux): Windows 10 x64 -

Mobile OS and Version: N/A -

Mobile Device Manufacturer and Model name: N/A -

Do the Vuforia Sample Applications show the same behavior?: Yes, the error appears after importing the VR+AR samples from the Asset Store.

This is likely a mismatch between the version of the samples downloaded, and the version of the SDK you are using. There is a Unity Asset Store limitation in that does not allow us to match the SDK and Asset version to insure the proper version is downloaded. Likely you're using the 7.5 samples with the 7.2 SDK, and some APIs have been updated.

Either that or you can edit the problematic script to update/remove these API calls.

I'm also having the same error, after downloading Vuforia Core samples and Book samples too. I'm using Unity 2018.2.13f1 and Vuforia 7.2.23.

Vuforia asks me to download and install Vuforia 7.5.26, but when I did the same all vuforia references are getting deleted.


Thanks in Advance, someone kindly help me out..
