Hi guys i have a game where you collect money, and then a menu, where i want all your money to be shown. I have a var called money, and a var called totalmoney. And i want to store all the money that i gain playing in that variable. For example, i play the game and i collect 20 money. And then this money has to be shown on the menu screen, well thats easy, in the menu screen you create a text saying:

game.add.text(128, 0, money+'$')

and the money will be shown, but what if i want to play again? I cant do the same thing because the money gained will overwrite the actual money, so guys any idea about what can i do?

I see. You should store the money in the web storage. That way it will be saved for your next session (if you don't delete the data of course).

Example: 


// That game session money should be stored on your global var money so just do:

var money (the one that contains your temp money)

if(localStorage.money == undefined) { // for the first save ever
   localStorage.setItem("global_money", money);
}
else {localStorage.global_money+= money}

Then just load the value of global_money when you need: var global_money = localStorage.global_money;

For the moment i only want to store it for one session, im not very experienced programmer and i dont really know how to implement that code you put above in my code :/, i would like to but i dont even understand what the code does, i mean i know what you want to do, but i've never used something like that before, and i preffer to dont use things that i dont know for what they're.  But i apreciate the help, this will be usefull for me in the future.

I don't think I understood the problem... Which one of these do you want:

  • .You play the game. You score 20. Then a menu appears saying "Money: 20$". You start the game again and you play and you score 15 this time. Then a menu appears saying "Money: 15$".
  • Or you play the game and you score 15. A menu saying "Money: 15$" appears. Then you start the game again and you play and you score 10. Then a menu appears saying "Money: 25$" (which is 15+10). The money adds to the previous game instances.

Is it any of these?

The second one is exactly what i want, but just for one session ;)

If you don't leave your game, like if you don't close your browser window, you just have to set a outer global var. Declare your var money right in the beggining of everything like "var money = 0;" and then just play with it as you want. When you init your game money is 0 but as you play and play and score you can add more money to it like money += money; Then you just access it. It has a global scope.

Anyway If you want to store money value "forever" (even if you close your browser window and reboot etc) you must add it to browser localStorage.
