When a project is packaged as UnityPackage, after importing other projects, the customized Tag and Layer in the project will be lost. The following method will automatically write its Tag or Layer into the user’s project when importing the UnityPackage package. Packing the following scripts with resources together, so that when other projects are imported into the UnityPackage package of the project, the program will call Addtag and Addlayer to add. judge.

The following code only adds one tag and a layer, modify the addition of N multiple tags and layers

Put the script under the project
