In this file atached you will learn how to Save your game and load from server and generate Unique IDS

How it works :

Start of layout will create a new and unique ID for your users if not created and saved before

using this api

uuidgenerator.net/api/guid

After this, the game will save the coins ( or your own data ) into localstorage

After this you will see a button export to server , when click it will create a file ( yourid.json ) in the server with the data from localstorage

you can modify it and create files like txt , csv , xml etc

so your data will be saved in the server with your unique id

after you export ( not before ) will be available a button " import from server " and on click it will call the file with your ID from server load it back into your array and save the new data into your game

so its a save and load system game

the button will be available only after exporting , because if dont and user try to import a file tha doesnt exist will give a error

if you understand how it works you will see that you can do a lot of things like give a user the ID and when the user uninstall the game and install again in other cellphone , pc etc .. he can put the id and load the data , dont need to create a login system

  • Thanks for important tutorial

    But if the player change his device how to check the same id (to import same number of coins for this player) ?

    because when he reload this page (uuidgenerator.net/api/guid)it generate a different id

    • abdalghani , Hi , yes this work like this , when reload it will be a different Id , because it generates unique ids, and the users only needs one ID and it saves in localstorage only once , for retrieve the data in the future you can send an email to the user with his Id , so you must make an request input from user to type his code if the user has one , and check into the server if its valid and retrieve the data

  • erorr on export, can you help?
