How do I keep a Timer after the game is closed?

I thought about using phone's time but it's easily exploitable and I don't really know how to do that too. Are there any simple and practical way?

It's, in other words, a countdown that I need to keep track to unlock certain things in the game. Then if the player shutdown the game it won't get lost.

Thanks!

Edit:

I found this great plugin but is this exploitable? Like changing the phone's time?

Have you tried using web or local storages?

if you're talking bout keeping the time in accordance to the current time. try making a global variable for time then allow the user to input time. then try to store it in a storage.

Its like the top ten high scores. but try this video. But instead, use time.

I HOPE THIS HELPS!

Sure, machine time could be changed by user.

You might try get timestamp from a server ( rex_firebase_timer plugin, or rex_parse_timer plugin )

Is it reliable? Because using a server that is not yours is unpredictable and could have the service ended in the future, which would ruin the entire game.

Thanks, rexrainbow .

I was looking at it and I'm getting the time elapsed since logout. But how should I manage different items (which will be unlocked once their own timer end) from different players?

Situation:

Player A

items 1, 2 ,3

item 1 : timer X

item 2 : timer Y

item 3 : timer Z

Player B

items 1, 2 ,3

item 1 : timer X

item 2 : timer Y

item 3 : timer Z

Is this enough?

On start of layout

Define the Player ID to Player A.

Get Timer "item 1" of user ID: "Player A".

Blank condition> Start Timer "item 1" of user ID: "Player A" When Disconnected.

Also, this item would have to be different every time to avoid two items share the same timer. Then, whenever a player earns a new item, it's ID would be Last item ID + 1. Am I following a correct logic regarding to firebase and your plugin?

Yes, I though it is correct.

BTW, firebase was bought by google, but I could not promise it will be reliable, or not.

rexrainbow I think it's not a good idea rely on that for something really important to the game then. Aren't there any reliable online source to get the hour? It's just a simple thing you know? Get the time online instead from the phone and then, internally, I manage to know if it's time to unlock the item or not.

"reliable" is a cost issue.

Build your own server will have the best reliable I agree, but it needs a lot of effort, not only write a simple program, running at a host machine.

Firebase might reliable online in one or two years recently, it is enough for normal case, imo.

( Parse will be closed at 2017, fortunately it had released a open source server for us. I had built it on heroku server already. )

rexrainbow Thanks for the advice
