Code COMMUNITYBOARD - RankingSystem (Top 15 PVP/PK)

[SweeTs]

@StinkyMadnessofc 1h delay is NOT a shit, you could even make it update once a day. Its like saying olympiad ranking is shit bcs it updates only once, at the end. Plus, there is shit load of connections happening here and there and you care for one more, mhm, okay

The lack of knowledge in this topic is monstrous.

Nobody said that its something super heavy to update it each one hour.
The point is to update as quick is possible (as if you are the only person that visit that page last 1 minute you will see it directly updated).

The point of timestamps its that works and player can see more updated statistic than waiting 1 hour for an info he is looking right away avoiding as many useless connections.. that's all.

Then, I got another idea. Make a thread pool for each 1min, even 1min and add a new variable flag. Like boolean updateRequested. As long as it's false, there is no update. Once player visit community board set flag to true and on next loop, update the link. So, you got control for "unnecessary connections" and "update on demand".

 

You eat cookie and still got cookie.

@StinkyMadness another approach to that if u want the real time update and not using threadpools every x seconds is to store the pvp's,pk's in a temp List holder. Whenever a player gets a pvp,pk  you update/store his incremented value along with his player info to the list. If user exists update his pvp or pk score with the new one ++ (pvp/pk) or add a new entry.

 

On server start: Feed the List with the first top x players from the database.

On requestbypass sort the list by highest values. If u want to avoid that u can use a sort algorithm and sort the list when adding new data and then u show the first x from the List as it is.

 

I dont know how stressful this might be for the server.

I don't see why its so complicated and have 3 pages on how should be.. every Raking system shared until today was ThreadPool + Connection each X minutes. I just shared one different approach to avoid as many useless task and mostly be updated each time player reach it.. that's all

There can be boolean for _requestToView and avoid update as far its false.. but its way more simple with one timestamp I guess.

You have to feed the CHM with all kills information's.

That's how its was one of my previews systems but this one its way more simple I think...

Even tho you're not my favorite person to talk with i have to admit that i agree with you and that all who comment here have limited programming skills regarding this language.

 

The way you made the code is not the proper in terms of  "synchronization". If you wanted make it like that use an AtomicReference, AtomicBoolean or work like CopyOnWriteArrayList which copy the content upon modification to avoid concurrent problems. Yet the whole topic's answer is a joke.

 

So please to stop this 3-4 pages spam, if anyone has better code than this share it. Here's is share section no general discussion. Thats the way this guy is coding. If you want teach him DM him or go in general discussion section.

BTW this is one year ago code, I share it because I updated mine, just aCis still not using JDK14+ to share my new version. Anyway.. its just one share to show one other way on statistic systems, can be improved can be worst than this share..

Simple and Nice

[xRelic]

i adapt it to my server,verry nice gj.
