Building the game
Building the game is simple, but since the game relies on AssetBundles to load scenes and other content, you will need to "build the content" first.
Building content means packaging all of the game's assets in AssetBundles, as defined in the Addressable Group window (to see it, use the menu item Window/Asset Management/Addressables/Groups). When ready to build content, go to the Groups window and choose the option called Build/New Build/Default Build Script:
This will produce the AssetBundles that will be stored in the Library folder at Library/com.unity.addressables/aa/[Platform], ready to be put into the build.
Once content has been built, you can kick off a regular build from the menu File/Build Settings... and then clicking the Build button. Notice that in the Build Settings window you should see only one scene in the list, called 'Initialization'. The rest of the scenes are packaged in AssetBundles.
Notice that if you only update scripts, you can create a new build without necessarily building the content first.
