[Not solved but im done.]How to save integers to a file.

[deadrecon98]

I wanted to know how to save integers to a config file. Not like item id's but just a basic integer. And also how to get the integer from the config file.

[Mazetar]

Seriously go learn Java!!!

 

Or at least learn to google basic java questions..

This has little to do with the forge API and is purely a Java question, a basic such as well..

 

Here ya go anyways

Im trying my best here dude, no need to be rude. And I have googled that at least 6 different ways and nothing I try works.

[Mazetar]

I'm pretty sure that's about as non-rude as I could get..

And I also gave you the link which would answer your questions I believe?

 

If they didn't work, then why not mention what you tried and what failed, and since it's not within the scope of this board to do java basics why not use stackexchange or some other page which is made around dealing with basic/general java/programming questions?

 

The method in one of the top links using writer works I have used it before in some of my programs.

And this from another of the top hits also works fine:

http://www.java-examples.com/write-int-file-using-dataoutputstream

 

If you can't get them to work I suggest you open a new project and try to just get this function to work as you wish, then do the reading part as well, after that you should be able to open your modding project and do the same there

Or... you could do things the easy way and use Minecraft's Configuration class.

That's going to cause problems if you try to use it on a server. You don't want to save that in a Configuration; you want to use EntityPlayer.registerExtendedProperties().

There's a local server even when you are playing on SSP, so there's a server and a client anyways

I know that but is all I need it to do is save and load from a file. The rest I can do myself.

If a config won't work then a hashmap maybe?

Why do you need it saved to a file?? Oh right, you need some way of doing NBT saves.

 

Try doing something like so:

[urlhttps://github.com/ModderPenguin/MinePG/blob/master/source/minepg/rpg_common/rpg/playerinfo/PlayerInformation.java[/url]

That source code is a bust, its very hard to understand someone elses coding when it gets to that level. I need someone to explain this to me so that Im learning. Not being a scriptkitty, im trying to get out of that.

I also am not being rude, but you should never accuse anyone of being rude when asking for help through a text means... that is actually rude in itself, but forgivable as it is frustrating getting something to work. If you cannot be bothered reading other peoples code then no one will want to help you... I don't think that's what you meant at all but if you are seriously considering modding, then you'll need to read a lot of other peoples code, and it will sometimes be very long and complex but should be well documented with comments. This API is not official and it's very obscured still. I understand your need to learn to gain the satisfaction of progress however, as you probably know, we all cannot help as much as we might like as we are working on projects, feeding family, working, and doing other things important to our own progress. Keep that in mind first and foremost when asking a question. Also, give a very good indication of your current skills, knowledge, and exactly what it is you want to achieve in your code. Saving an int to a file is generic. It would help to know what the purpose of doing so is and think how that feature may evolve later.

 

It's good to want to get better but I'd have to know a lot more about your current knowledge of java and forge to help teach you something. Have you done all of the Basic tutorials? http://www.minecraftforge.net/wiki/Tutorials. Indispensable. If it becomes frustrating to follow just keep trying. You can teach yourself anything if you apply yourself and do not allow frustration to set in. I have a feeling if you have a decent enough base knowledge of java that following the basic tutorials will allow you to intuitively discover your solutions for quite sometime. I do understand the frustration that can come if you are just getting into things as a new coder. I guess the idea is that if someone does it for you you won't learn anything, but no one should have a problem if you don't understand a particular class, in giving you some ideas or help.

 

If you are simply wanting persistent data that saves and loads on a save game, you should grok the classes for NBTTagCompounds.  This is how Vanilla saves most of it's persistent/unique data when the game saves. If you have something else in mind that minecraft doesn't already do then you may need your own data file system... however I doubt it would be necessary. It does require knowledge of java's file input/output classes. If you don't understand them, I suggest you try a basic java app first then play with the classes. If your knowledge of java is up to snuff then I'd master all the knowledge gained from the Basic Tutorials then amaze yourself at how much can be learned with a bit of patience and persistence.

 

Also, let the vanilla source guide you. ctrl+H in eclipse will let you search for text in all the packages open in your project. It's probably done me more good than the tutorials...

 

Update:

I just remembered something important. I understand that you are making a SSP mod. It is important to understand that a client and server are running even in SSP. Not much gets sent to the Client but rendering data. Even the levels, skills, other info would be on the server and the server value would be passed to the client either through a datawatcher or packet. I think the concept works best mentally if you say that the client cannot be trusted. The server is the master in this case and does all the saving of data. It's probably less intuitive but things got easier for me when dealing with Server/Client relations when I thought of it that way. But that could just be me.

[deadrecon98]

Dude I've tried literally everything that I can think of. Hashmap's, NBT, FileWriter. But none of it seems to work for me. I've just never worked with these elements before and can't find anyone who knows or is willing to help me here. And btw I did read that guys code, actually I stripped it down and tried it then but it was still broken.

[Draco18s]

Step 1: get a reference to the player (object type EntityPlayer)

Step 2: get a reference to the player's NBT data:

player.getEntityData()

Step 3: write an integer to it:

nbt.setInteger("MiningLevel",lv);

Step 4: anywhere you need to reference the mining level, read it from the NBT:

nbt.getInteger("MiningLevel");

Step 5: if it changes, go to step 3.

Is there anything that I am missing here?

 public static void hashSaving(EntityPlayer player){
    	player.getEntityData();
    	map.put("MiningXp", MiningXp);
    	map.put("MiningLevel", MiningLevel);
    	map.put("SmithingXp", SmithingXp);
    	map.put("SmithingLevel", SmithingLevel);
    }
    
    public void getMiningXp(){
    	map.get("MiningXp");
    }
    public void getSmithingXp(){
    	map.get("SmithingXp");
    }

 

Note: I can change the integer values but they don't save.

[Flenix]

deadrecon, I don't suppose I could see the whole class could I? I'm trying to figure out the whole NBT on the player thing atm, can't quite figure it out...

Well you're kinda missing the entire read/write nbt parts...

Yes you may see it. If you need anything else just ask, I really want to get this done so that I can start working on the modding API for it

You don't need the hashmap though, if you're saving and getting from the NBT compound!

        MiningLevel = nbt.getInteger("MiningLevel");
        SmithingXp = nbt.getInteger("SmithingXp");
        SmithingLevel = nbt.getInteger("SmithingLevel");
    }

    }

    public void saveSmithingXpForPlayer(EntityPlayer player){
        NBTTagCompound nbt = player.getEntityData();
        nbt.setInteger("SmithingXp", SmithingXp);

But with nbt you cant load it from another class file wich is what I need to do.
