I have just tried downloading a library which will allow me to add animated tiles to unity. I have been following this tutorial:http://shadowpeakstudios.com/2018/10/22/unity-tutorial-animated-tiles/
It told me to download this library in order to work the animated tiles: https://github.com/Unity-Technologies/2d-extras
After this the tutorial told me to unzip the library and place it into my assets folder. It loaded into my assets folder and then got the following error:
Assets\2d-extras-master\2d-extras-master\Editor\Tiles\RuleTile\RuleTileEditor.cs(277,26): error CS1061: 'ReorderableList' does not contain a definition for 'IsSelected' and no accessible extension method 'IsSelected' accepting a first argument of type 'ReorderableList' could be found (are you missing a using directive or an assembly reference?)
Does anyone perhaps know why this error is occuring.
