Solved Played time

Hello people,

I am making a plugin which makes use of the played time of a player.
But the problem came early:
- I can't use the stats of mc itself because these will be deleted when players re-install mc.
- I thought that I couldn't use a scheduler for it either, because it would become laggy if there are a ton of players on the server.

Does somebody know how this works, and help me out?

 

@Just_Jitse

1. Create a HashMap with UUID and Long
2. When they log in, store their UUID and System.currentTimeMillis()
3. When they log out, use their UUID to grab their login time
4. Subtract the login time from a new System.currentTimeMillis()
5. Now you have how long they played!
6. Store that info somewhere(yaml or database) and add to it next time you reach step 5!

 

How do I do that @Gamecube762?

 

@Just_Jitse Well where are you at and what do you need help doing?

 

@Just_Jitse

If you know what you're doing, it will not be laggy. This would actually the best way, and the way that uses the least amount of memory if done correctly.

 

It would not be the best way... Why would you want to run a bit of code every x amount of time when you could just store the time they log on, and the time they disconnect, and then get the time online from that?

 

@Just_Jitse offlineplayer has an option getFirstPlayed

 

@caderape Unless the player will stay online 24 hours everyday, this will not give their play time, but the time since they joined for the first time.

 

@Just_Jitse

What don't you understand about this? It's really quite specific.

 

@Just_Jitse Using what @Gamecube762 said would look like this: (I didn't use an IDE so forgive any mistakes)

Code:

HashMap<UUID, Long> time = new HashMap<UUID, Long>();

//event
@EventHandler
public void onLogin(PlayerLoginEvent event) {
    time.put(event.getPlayer().getUniqueId(), System.currentTimeMillis());
}

//other event
@EventHandler
public void onLeave(PlayerQuitEvent event) {
    Player player = event.getPlayer();
    long t = System.currentTimeMillis() - time.get(player.getUniqueId());
    // t is now their time in milliseconds that they have been on.
}

 

@567legodude #SpoonFeedingIsNotRecommended

 

@nverdier That makes it too easy. You think I would know about all this if someone just said "do this" and didn't explain any of it. No, I learn each part and how it works, then combine the parts to make the whole.

 

It's still spoonfeeding and it's still not recommended.

 

@567legodude It's the job of the one who is learning to figure out how to code, not the ones trying to teach it. If he never learns how to create the code himself, how will he ever make something new?


If you must create code, use pseudo code("Not" code). Pseudo is fake code used to develop understanding and is not copy-able(to an extent). A computer will not be able to read pseudo code since its not real code, which will make it so it can't be copy/pasted.

Example:

Code:

Public void giveMeCookies(Player, amount)
if (player.inventory.contains(Cookie)) then Player.tell("You already have a cookie!!!")
else Player.inventory.add(Cookie, amount)
end

 

@nverdier @Gamecube762 That's my point, you can't learn that way so you don't do it.

 

Then why'd you do it??!!?

 

ow, okay. Got it.
Thanks all!
