// Code to make Unity assets "addressable"


// Use this object to manipulate addressables

var settings = AddressableAssetSettingsDefaultObject.Settings;


// Create and Remove groups and labels and custom address:

string group_name = "YourGroupName";

string label_name = "YourLabelName";

string path_to_object = "Assets/path/to/your/object/";

string custom_address = "Custom address here";



//Create a group

settings.CreateGroup(group_name, false, false, false, new List<AddressableAssetGroupSchema> { settings.DefaultGroup.Schemas[0] });


//Create a Label

settings.AddLabel(label_name, false);


//Remove a group

AddressableAssetGroup g = settings.FindGroup(group_name);

settings.RemoveGroup(g);


//Remove a label

settings.RemoveLabel(label_name, false);



//Make a gameobject an addressable

AddressableAssetGroup g = settings.FindGroup(group_name);

var guid = AssetDatabase.AssetPathToGUID(path_to_object);


//This is the function that actually makes the object addressable

var entry = settings.CreateOrMoveEntry(guid, g);

entry.labels.Add(label_name);

entry.address = custom_address;


//You'll need these to run to save the changes!

settings.SetDirty(AddressableAssetSettings.ModificationEvent.EntryMoved, entry, true);

AssetDatabase.SaveAssets();

So many helpful snippets here
