Share data across the games

hi, everybody

in my project a large amount of minigames. and because there are too many of them, project became heavy, and loading time is slow. so i decided to create a launcher. the problem is how to transfer variables across minigames. for example Music On/Off, users progress, ets.

i googled that two pages share the same local storage if their origin (domain) is the same. but cant really make it happen...

launcher

minigame

in google chrome i can see the "path" key is stored, but i can't reach it...

here you can try the result https://youthful-turing-643bff.netlify.app/

here is capx files. 0 - launcher, 1 - minigame https://dropmefiles.com/B1DEk

any help will be appreciated

I believe you can only access local storage data from another game if it's on the same domain, and if it has the same app ID.

If you need to use different app IDs in your minigames, then they'll not be able to share local storage. You will have to send data to services like Firebase, Playfab, or store it on your own web server.

thanks, i'll give it a shot

Turned out I was wrong about the app ID. Seems like there is a "uniqueId" tag in .c3proj file, which is probably generated when you create a new project, and which works as a storage identifier.

Try setting the same uniqueId for all your minigames and see if they can share Local Storage after that.

It's odd that this feature is undocumented..

dop2000 this is a bit of a revelation! I'm building a similar setup to OP, currently passing URL params back and forth which is fine, but not exactly convenient.

Ashley can you comment on this "hack"? Obviously undocumented features should be avoided at all costs, but are there any issues or caveats you foresee if one were to use this method to share data across apps?
