Downloading A Scene and/or Assets for use in-game

Hi everyone.
I am struggling to figure out a way of implementing an in-game asset/scene download feature like those in mobile casino games.



There are tiny download icons on each slot game.
Each game takes roughly 30MB of space

How would I go about implementing something similar to this with Unity?

 

You break up all the assets for each mini game into its own Asset Bundle. You download the Asset Bundle as needed. All of the code has to be integrated into the main game binary, as code can't be included in Asset Bundles, but code doesn't take up much space.

 

What Uncle Joe said above is spot-on... and when you design your AssetBundles, always use complete Scenes rather than collections of tons of random assets. If you use the latter, you will have to write specific code to load and connect every piece, whereas if you use the Scenes-type of asset bundle, you just load the scene and you're done.

 

addressables would also work with this download and load the appropriate assetpack when appropriately called

 

Thanks for the replies. I am currently getting familiar working with Asset Bundles. I just have one more question.
I am planning on publishing my game on the Google Play Store. Would I have to add those files with the apk file on the release page? I assume they won't let me pull data from a random server.

 

Not possible. You can only have the signed APK or AAB and any OBB expansion parts, not just stray files.

Actually this is exactly how you do it. But you're welcome to stick it in the Streaming Assets folder in Unity3D too, which gets it pulled into the build. But if that's all you're doing, it begs the question of why even do it: just access the resources "normally" in Unity.

 

How exactly would this be done. I've been struggling to find an answer to this question on how to use addressables for this sort of download
