Hey guys! I am trying to save some data in my game, but it just isn’t working.
I want it to be stored in the device itself, and not on the sd-card. That is why I use the Internal Only selection, on the Player Settings.
Below is my script. I tried fixing it, looking everywhere, but got no answers. I did choose to use Binary Formatter instead of Player Prefs because I believe it is safer, and easier to use. Perhaps I shouldn’t be using it at all…
In the Editor everything works fine, and data is saved. The problem is building at Android. By the way, I didn’t test yet on iOS, but wouldn’t be surprised if it didn’t work.
