Unity has changed the 2D Extras. It says lower down under Notice, on this page:
“We are changing how we develop additional 2D Tiles and Brushes for 2D Tilemap. An important part of this change involves ensuring a single point of entry for users to get the latest tiles and brushes for Tilemap. To this end we created the Tilemap Extras package which is accessible from Package Manager.”
However, this page, explains, under Getting Started, how to get it:
https://forum.unity.com/threads/tilemap-extras-preview-package-is-now-available.962664/
It says it is in Preview, but I’m guessing that once we use Rule Tile to place the tiles, that it won’t be using this, so it should be safe (or most of it, but correct me if I’m wrong - I’m just starting to use it).
Then right click in Assets folder, and:
Jim
