Unity3d import picture automatically modifies texture type to Sprite (2D and UI) and set Packing tag as folder name

Unity3d's new UI system has brought us a lot of convenience, but also added a little bit of trouble. Each time you import pictures from your computer to Unity3d you need to manually set texture type to Sprite (2D and UI) and set Packing Tag. For pictures that need to be packaged as an atlas, we typically put them in a folder. Based on the above, we can make the Packing Tag of the picture automatically set to the name of the folder.

Unity3d provides a callback function for resource import, and we can use Assetpostprocessor to perform some of our own processing before and after the Unity3d processing the image.

Here, we first modify its Texture Type and Packing Tag before the image is Unity3d processed.

You can refer to Unity3d official documentation for details.

Put the above code file in the Editor folder (not the rules, just the habit).

Then drag a picture from your computer into Project view and you can see that the picture is automatically modified.
