Get the player's NBT object,

NBTTagCompound nbt = player.getEntityData();

then

nbt.set<OBJECTTYPE>("keyofobject", valueofobject);

and replace <OBJECTTYPE> with the type of object you want to store. (ie; Boolean, int, String)

 

 

So for a number (lets just say that the number is a float)

NBTTagCompound nbt = player.getEntityData();
nbt.setFloat("examplefloat", 1.3F);

That's all you need to set it. Then to get it, you simply use the player object again.

NBTTagCompound nbt = player.getEntityData();
float value = nbt.getFloat("examplefloat");

Lol I mean like nbt.getInteger("MiningXp" + 1); but that method just says that the left-hand side must be a variable and just using the int itself won't work. Any Ideas?

I'm toying around with the same kind of thing, but with an economy system, so I've been following this post :P

 

To add on to an existing int, I think it would be something like this:

 

public static void saveBalanceForPlayer(EntityPlayer player, World world) {

NBTTagCompound nbt = player.getEntityData();

nbt.setInteger("Balance", (nbt.getInteger("Balance") + moneyValue));

}

 

In my setup, "Balance" is the players balance as an NBT tag, and "moneyValue" is a static int defined in each of my different coins classes. You'd simply replace moneyValue with the amount of XP you want to add, but by doing something like that you can give different XP for different things relatively easily.

 

 

 

What I want to know; is A) how do we trigger this change (How do I say "You should now add moneyValue to the NBT"), and B) How can I see my current NBT value?

Whenever you change a value, you have to use nbt.setInteger instead of nbt.getInteger.

 

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

Use a command? An eventlistener for rightclick with a certain item? I don't know, you could use pretty much any event trigger... For current NBT value, it's just

Integer currentBalance = nbt.getInteger("Balance");

Ty, I just updated to 1.6 so I have to wait to be able to run it. the renderEngine.bindTexture is broken.. god dammit mojang

It's a really simple fix for that, take your old:

mc.renderengine.bindTexture("texloc/wherever/yours/is");

and edit them to be:

mc.func_110434_K().func_110577_a(new ResourceLocation("texloc/wherever/yours/is"));

 

lol ty. where do you find this stuff btw? it would help me in the future :3

It looks like you've got it all right and triggering it isn't much different and to see it just use a string + the int.

ummm dude. i updated to 1.6 and the nbt doesn't save anymore.

I was about to comment :P My NBT isn't saving. Here's the code:

 

    @Override
    public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int i, float j, float k, float l) {
    	TileEntity tileEntity = world.getBlockTileEntity(x, y, z);
    	NBTTagCompound nbt = player.getEntityData();
    	if (player.getHeldItem() != null) {
    		if (player.getHeldItem().getItem() == FlenixCities.debitCard) {
    			player.addChatMessage("Your Balance is: " + nbt.getInteger("Balance"));
    			player.openGui(FlenixCities.instance, 0, world, x, y, z);
    		}
    	}
    	if (player.getHeldItem() != null) {
    		if (player.getHeldItem().getItem() == FlenixCities.note1000) {
    			nbt.setInteger("balance", (nbt.getInteger("Balance") + ItemNote10.moneyValue));
    			player.addChatMessage(ItemNote10.moneyValue + " Deposited! Your balance is now " + nbt.getInteger("balance"));
    		}
    	}
	return true;
    }

 

As you can see, in the confirm deposit line, it gets the current NBT at what it is, and reports it's 1000 (which is correct) - however, when I use the debit card after which merely displays the balance, it's back to 0.

I got really excited when it said I'd deposited 1000 then really sad again after :(

I looked in the vanilla classes which used to use that bindTexture method, then checked what they had changed to when my methods no longer worked.

As for saving issues, I think it might have been a fault on my part... Try changing this:

NBTTagCompound nbt = player.getEntityData();

to this:

NBTTagCompound nbt = player.getEntityData().getCompoundTag(EntityPlayer.PERSISTED_NBT_TAG);

now I can't add to the nbt integer -_-

Meh, we're working early. Give it 3-4 weeks and there will be fixes in forge, and plenty of "how to fix this update bug" tutorials. I didn't update to 1.5.2 for a couple of months and minus the texture de-stitching that didn't take me long at all, coz I could just google any issues :P

 

Anyways. I added that extra bit to the code, still getting the same bug:

    @Override

    	TileEntity tileEntity = world.getBlockTileEntity(x, y, z);

Hmmm... Try using NBTExplorer and check if the NBT objects are actually created in the level.dat. The Balance key should be in saves/<worldname>/players/<playername> , let me know if it's not there.

 

Obviously I'm testing in the Forge environment so all of my .dat's are different. But, they all seem to have the same Balance of 1000. However, most times of logging in I tried to do it at least twice, so it's obviously still not adding properly else there would be some with 2000, some with 3000, some with 0 etc..

 

Screenshot if it's any help:

Lets try some console output debugging.

    @Override
    public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int i, float j, float k, float l) {
    	TileEntity tileEntity = world.getBlockTileEntity(x, y, z);
    	NBTTagCompound nbt = player.getEntityData().getCompoundTag(EntityPlayer.PERSISTED_NBT_TAG);
    	if (player.getHeldItem() != null) {
    		if (player.getHeldItem().getItem() == FlenixCities.debitCard) {
    			player.addChatMessage("Your Balance is: " + nbt.getInteger("Balance"));
    			player.openGui(FlenixCities.instance, 0, world, x, y, z);
    		}
    	}
    	if (player.getHeldItem() != null) {
    		if (player.getHeldItem().getItem() == FlenixCities.note1000) {
                                            System.out.println("Old balance is: "+nbt.getInteger("Balance"));
                                            System.out.println("Adding "+ItemNote10.moneyValue+" to total balance.");
                                            int newBalance = (nbt.getInteger("Balance") + ItemNote10.moneyValue);
                                            System.out.println("New balance is: "+newBalance);
    			nbt.setInteger("Balance", newBalance);
                                            System.out.println("Balance confirm:"+nbt.getInteger("Balance"));
   			player.addChatMessage(ItemNote10.moneyValue + " Deposited! Your balance is now " + nbt.getInteger("Balance"));
    		}
    	}
	return true;
    }

Try that a few times and check if the output is what it should be.

Everything printed twice but I cleaned it :P It seems like it's just not saving the balance after it confirms it's been added =/
