Keeping Progress Data

Is there a way to keep progress data even through updates? I wouldn't want any published updates I make to make users lose their data so how would I prevent that?

    I'm pretty sure saved attributes are not written over when an app is updated ?

    Hopefully someone with a little more insight into this kind of thing will chime in.

    @Socks is right, they stay saved

    There's a save attribute /load.

    Is there a save table/ load behavior? Not at my computer to check.

    @Socks I was wondering if saving tables like saving attributes means they dont get overwritten when updated. I suppose they do then. Thanks yall.

    I believe the save table attribute rolls over into update versions as well

    they do aslong you dont add new cells in tables were players already have saved versions of on their devices. So make in advance enough cells in tables you "save"

    i only use tables to save data. So I can always decide to upgrade to save on a server (appformative)

    Yeah I'd recommend making quite a few blank columns of each type if you think you might need more columns at a later date. I throw in 2 or 3 blank columns of each type i.e. text, integer, boolean etc. While I've not experienced the loss of data due to updating tables I've read about it on the forums to not risk it (not that I really publish games)

    @BigDave @KevinCross So If I make extra columns of each type and then eventually add data into them several versions later will that not overwrite the contents of the table of the saved version on the device?

    Two suggestions.

    Table Migration

    When updating your game and adding columns to a table:

    • Make a new table with the new columns.
    • Change your games to use the new table.
    • Make an actor whose job is to copy data from the old table to the new one when the game starts. Maybe make a special "upgrading" scene.

    Online Storage

    • Store table data online.
    • Version your games in an attribute and make sure to send that version with the Load Table From Network request.
    • Your server code should return the correct table for the game version.
