Error CS0117: 'Selection' does not contain a definition for 'objects'

[nernada]

Hi there,

I'm a new game developer working with a designer that used Gaia. I'm trying to import the unity package but runtime of game now has many errors. It seems to have the same issue but across all components.. Wondering where do I begin with troubleshooting this? 😞

Adding that me and my designer both used Unity 2021.3.18f1. However I was using Mac M1 and my designer was using Windows.

Hi @nernada, it looks like another asset or one of your own scripts is overriding the class name "Selection" in the project, which then leads to the errors you are seeing.
You can double-click on the error and hover over the term "Selection" in the code; this should show you where that term is resolved to in that project - it usually should point to the class "UnityEditor.Selection" like so:



In your project, it most likely points to something else. You should then be able to right click on the term "selection" and select "Go To Definition" to find the file that makes that definition that overrides the meaning of "Selection" for the entire project. This can either be a script file, or a DLL library.

If this is one of your own scripts, you should use a namespace for your own code to avoid such conflicts. If this comes from another asset developer, you would need to contact them with this error and ask them to fix this from their side, they should be using namespaces as well. 

Alternatively, you can crawl through all of the errors in the Gaia code and change "Selection" to "UnityEditor.Selection" to work around this issue, this would however be reverted when you update Gaia again.

Wow thank you so much! This did the trick!!
