[Solved] Saving data about a player

NuclearFej · March 25, 2013

How can you save data about a player?

For example, money.

I assume this would be done through NBTTagCompound but I can't find anything relevant about saving tags to players.

Thanks!

(Saving data to an external text file or the like would work as well, if that is possible.)

How, exactly? I can't find any information whatsoever on this interface.

Thanks!

Take a look at the IExtendedEntityProperties file which can be found inside the "minecraftforge.common" package or by pressing CTRL+SHIFT+T(in eclipse) and use the "Open Type" window to find it by entering IExtendedEntityProperties into the box.

Then take a look at the bottom of Entity.java inside "net.minecraft.entity" package.

The two last methods there are dealing with the extended properties.

I haven't seen it before now but it seems quite awesome,

Thanks diesieben07!

Can you give an example, if possible? It's still unclear exactly what I need to extend/override.

Thanks!

How does this look to you guys?

Thanks for all the help!

import net.minecraft.entity.Entity;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;
import net.minecraftforge.common.IExtendedEntityProperties;

public class DataSaver extends TileEntity implements IExtendedEntityProperties {

String testString = "";

@Override
public void saveNBTData(NBTTagCompound compound) {

	super.writeToNBT(compound);
	compound.setString("test01", testString);

}

@Override
public void loadNBTData(NBTTagCompound compound) {
	super.readFromNBT(compound);
	testString = compound.getString("test01");
	System.out.println(testString + " loaded.");

}

@Override
public void init(Entity entity, World world) {

}

public void writeString(String par1)
{
	testString = par1;
}

public String getString()
{
	return testString;
}

}

and when I need to access or save data...

((DataSaver)player.getExtendedProperties("FejProperties")).writeString("xyz");

For note these are new features that I have not reviewed fully as I have been out of town.

I can however tell you for a fact that these things WILL be changed when I get back from Sakuracon as they need cleaning. However, there has been the basic functionality to tag any entity with extra NBT info for a long, long time. So just use that.

NuclearFej · March 27, 2013

In that case, how would I save NBT tags to players, um, normally?

Thanks!

Much better question:

I assume I cannot attach a TileEntity to a player, as TileEntities have a fixed position in the world. So, then, I need to attach the NBTs to something else. What can I attach them to in order to have them attached to the player, and what method can I use to get the object from a EntityPlayer?

This is assuming I don't use IExtendedEntityProperties.

And when the TE is unloaded? Better off storing and writing to a custom nbt file. Just use event a packets and commands to tell where and when to send it

NuclearFej · March 28, 2013

How do you write to a custom NBT file? I can't find anything even similar to a filename in the NBT code. I'm probably missing something

Wow. That was so easy, especially compared to the IExtendedEntityProperties! Thank you so much!

I think I'll write a tutorial about it as well, as long as that kind of thing is wanted by the community.

the topic is 7 years old... either everything here is useless or you need to update. If you are on a supported version, create a new topic
