I had this happen to me so I thought I would add to the thread in case anyone else comes across it. The adverts package was installed for me so I uninstalled, then re-installed and the errors went away.
@PolymathicIndustries, I updated Advertisement to 3.7.5 (the latest and greatest), closing and re-opening the Unity editor two of times. No joy. I get the same error:
Assets/scripts/WWIFC.cs(28,37): error CS0246: The type or namespace name ‘IUnityAdsListener’ could not be found (are you missing a using directive or an assembly reference?)
It seems like they’ve made some “braking changes” that everybody love so much))). Support gave me a link on new version of implementing (you should use all three new interfaces, as for me that worked) i’ve copied the code and made some minor changes (like removed button). Had some practice in reading docs)) https://docs.unity.com/ads/ImplementingRewardedAdsUnity.html
Not sure if you still need a solution, but for future viewers, this is an update issue. To resolve this head over to the package manager, select Advertisements as shown in finneous’ screenshots above, except this time you need to update it. Click on Advertisements and select/click on the latest/higher number. Once up date your package to the latest version the errors in your IDE will go away, having been resolved.
I think the interfaces have changed for unity ads, there are now 3 listener interfaces instead of 1 and the formats have changed significantly. But the worst part is that it is not mentioned in the change-logs or documentation but only in the examples.
I also came across this same error… This happened when I duplicated the original project for random changes which I don’t want to make in original project, however original project is working good and whereas duplicate project having these errors.
Originally I created the copy of real project to have separate work space for every different app store, because every other store requires unique SDK for monetization, so implementing them means major changes in project and I don’t want to take any other risks.
Fixed it by changing plate form to android (lol) and then updating Advertisement to latest version.
I believe @finneous is having similar scenario.
Hi there i have the same problem, i came back to unity after a year and get that error, i read some documentation but i can’t figure out how to fix it. i have Ads Meditation Installed version 1.0.0 and Advertisement package version 4.3.0
Thanks in advice! @finneous
