How to save data with a webGL build?

Unity Engine
1

Hey guys, I use serialization in my game for the windows build, and want to make a webGL build so I can host it on online websites, and serialization didnt work. I made everything playerPrefs next, which said that it will save in the internalDB in the browser, and it also didnt work for me. I did a windows build with playerprefs and it worked, so my code is fine, just the webgl version is giving me problems. Is there anything I am doing wrong? Do I have to use a database for this simple game? Does anyone else have experience doing this? Thanks!

Depending on where your game is located online, playerprefs doesn’t work. For example, on Facebook or Kongregate due to the fact the game plays in an iFrame(so other sources will not work either). WebGL can not use system.IO either, so anything relying on it will not work either.

You will need to use a database or a free backend. I would suggest if it’s not a lot of data, look into PlayFab as it’s got a free tier that is pretty decent for small projects.

Thank you very much! I will look into this and see if I can figure it out haha.
