[1.8][SOLVED] A few questions regarding server modding with 1.8

[Jacky2611]

I KNOW THAT MOST LIKELY SOME OF THIS QUESTIONS HAVE ALREADY BEEN ANSWERED BEFORE, BUT TO MY SURPRISE THE SEARCH FUNCTION COULDN'T FIND ANYTHING RELATED TO 1.8 MP.

I AM SORRY IF THIS IS A REPOST:

 

 

Hi!

 

We (=22 friends + me) recently started a HUGE hunger games/survival sort of thing in minecraft 1.8 on a private server.

However, it turned out that some player have a way too big advantage cause they are able too stay online longer than others.

Now i had the (not really) brilliant idea to write a server only (thats possible in 1.8, right?) mod to kick players if they are online for more than 1 hour a day.

But bevor i can start such a project there are a few questions:

 

1. Can I use Events on a server only mod (and are forge events already possible?)

2. How far is the deobfuscating process?(just for basic stuff, i hate strange names in my code)

3. Do the clients really need no forge?

 

4. I would use a living updated event and player nbt data to save the online time and to check wether a player should be kicked. However, i believe that this could turn out to be really resource intensive. Any better idea?

5. Should i kick them whenever they try to join or should i ban them once they used up their time and then tell the server to unban everyone at midnight?

6. Whats the best way to execute a class at a specific (real) time even if there are no players online?

7. Anything else i should know about server only modding?

 

 

Whoa, thats a lot of text. A quick answer would really be awesome, we want to reset our server asap. =D

And would such a mod be useful for other servers too? Not sure if i should add stuff like a config file or not.

 

Thank you very much for spending some of your time to read my post, have a nice weekend,

Jacky

 

 

(I am NOT asking for updates, pls just tell me whats already possible)

[Jacky2611]

Whoa, thx! That was fast!

 

6. Unban my players

 

7. Yeah i guessed so. Anything else?

[Jacky2611]

Just wondering. How much do dimensions require client stuff?

 

Nah, i don't really want to use threads. The last time i used them i got an extrem performance boost and an awesome matrix like time freeze effect. But this time i won't have to sync anything so i could give it a try. Will they be shut down together with my server? (As already said, i never really used them)

[Jacky2611]

Nah, I will just try it. The one major reason why i started modding was to improve my coding skills.

 

CHALLANGE ACCEPTED!

 

Btw, this is solved. Maybe i will post some experiment results here but my questions have all been answered.

Thx diesieben07, you helped me a lot.

Then you try it again and it works again. This is due to the nature of threads. If you don't know about these things you will have a hard time.

 

So true.  Due to the way some of the events I'm using interact with threads (that is, they're fired on different threads and my handler wants to use the same not-thread-safe object) I've had quite a bit of trouble squashing some concurrent modification crashes.  I think they're gone, now, though.

Just a bit of a tip - you can use newer mcp mappings to get better naming. Nearly everything has been named by now in the daily snapshots.

If you're going with multithreading, you will most likely have race conditions in your code if you're not careful.

 

If you don't know what race conditions are, I suggest you don't use multiple threads. Given their non-deterministic nature, they are one of the most painful things to debug.

 

Also, when dealing with threads, you can run into deadlock. These seem like infinite loops (i.e. the program won't move on), but they are caused when two threads are waiting for each other to finish before moving on to their next tasks. That is, thread 1 waits for thread 2 to do something, but thread 2 is waiting for thread 1 to do something else (which thread 1 can't do because it's waiting for thread 2... and so on). These are much harder to spot than infinite loops, since there's no exact line in the code that causes this. (An unfortunate thread execution order/race condition can result in deadlock.)

 

To actually improve your coding skills, start with a better understanding of the foundations first. Don't go head first into something complex like multi-threading, since that will only frustrate you when you run into problems and lack the foundations to reason through them.

I already did nearly everything expect more advanced threads and advanced reflection(already tried it a few times in other projects).

I have been using java for over a year and spend most of my weekends coding.

 

And how can i use newer mcp mappings?
