Server side integer saving?

Recommended Posts

Why not?

 

Because the code I need cannot be used. Let me explain..

 

try{

compound = whatever;

}catch{

//Exception Here

}

 

I cannot use compound anywhere else except for the try/catch statement.

 

Initiliaze the variable outside of the try catch like this

NBT compound = null;

 

try{

compound = CompressedStreamTools.read(stream);

}catch(Exception e){//handle}

 

now you can access the compound variable anywhere.

 

compound.whatEverTheHellYouNeed();

 

*******

 

If it helps toss me a thank you.

 

Umm dude, it doesn't work...

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Dude I know basic java

 

then i suggest learning "advanced" java... or rethinking your definition of "basic". i remember your old thread and all you needed to know was already posted in it multiple times. people even posted code for you. the only thing stopping you from making your stuff work was.. well, not having a firm grasp of basic java..

Enough of this. If anyone can help me then reply, if not then do not even bother. I'm not trying to be rude but this is ridiculous.

"Doesn't work" isn't a precise enough description of your problem.

Try again.

 

I still don't get why you couldn't put your code in the try block by the way.

 

if(nbt != null) {

  nbt.setInteger("Test", nbt.getInteger("Test") + 1);

  entityplayer.sendChatToPlayer("" + nbt.getInteger("Test"));

}

You are still not describing your problem enough.

 

Where is NetherSpellBook.dat ? Did you put something in it ? How did you write it ?

 

Did you put any breakpoints while testing those lines ? What is each variable value at runtime ?

 

If you have an exception thrown, what is the offending line and the type of the issue ?

No no no, the file is yet to be created, is all it will be used for is to save data, it is not a config file.
