Hello and thanks for reading.

 

I'm trying to store nbtdata to see if a player has researched a item.

I'm now storing the nbtdata to an itemstack but that means everytime I get a new itemstack the player would have to research it again.

 

How would I set researched to "true" for every type of that item?

 

Thanks for your help!

Yeah I have seen something like storing the data per player using that

After a bit of fiddling around with nbt I noticed that you can't store a string array? are there any equivalent methods for this? setbytearray?

 

Or should i set everything in a large string? like: "grass,dirt,air"

I think that would be kinda slow because I'll have to iterate through the string if I want to check for a block. Because if I wouldn't split the string it could return true if it'll look for grass and I only have Grass Block for example

Performance should not be a problem. A comma-separated array should work just fine.

You could also have an NBT tag compound with the recipe name as the key, only storing simple booleans. To determine if something is unlocked, you would have to check if the NBT tag compound contains the key instead.

Ah well for anyone interrested heres my sourcecode:

 

playerclass:

package molecularscience.api;

import net.minecraft.entity.Entity;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;
import net.minecraftforge.common.IExtendedEntityProperties;

public class ExtendedPlayer implements IExtendedEntityProperties
{

public final static String EXT_PROP_NAME = "ExtendedPlayer";

private final EntityPlayer player;

private static String researches;

public ExtendedPlayer(EntityPlayer player){
	this.player = player;
}

public static final void register(EntityPlayer player){
	player.registerExtendedProperties(ExtendedPlayer.EXT_PROP_NAME, new ExtendedPlayer(player));
}

public static final ExtendedPlayer get(EntityPlayer player){
	return (ExtendedPlayer) player.getExtendedProperties(EXT_PROP_NAME);
}


@Override
public void saveNBTData(NBTTagCompound compound){	
	NBTTagCompound properties = new NBTTagCompound();
	properties.setString("researched", this.researches);
	compound.setTag(EXT_PROP_NAME, properties);
}

@Override
public void loadNBTData(NBTTagCompound compound){
	NBTTagCompound properties = (NBTTagCompound) compound.getTag(EXT_PROP_NAME);
	this.researches = properties.getString("researched");
}

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

public static void Research(String item)
{
	item = item + ",";
	researches = researches + item;
}

public static boolean IsResearched(String item){
	if(researches != null){
		String[] researched = researches.split(",");
		for(String p: researched){
			if(p.equals(item)){
				return true;
			}
		}
	}
	return false;
}
}

 

itemclass

package molecularscience.moditems;

import java.util.List;

import org.apache.commons.lang3.StringUtils;

import molecularscience.Config;
import molecularscience.MolecularScience;
import molecularscience.api.ExtendedPlayer;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;


public class ItemSample extends Item {

    public ItemSample()
    {
        super();
        this.setHasSubtypes(true);
        this.setCreativeTab(MolecularScience.Molecules);
    }
    
public void addInformation(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, List par3List, boolean par4) {

	String Itemname = par1ItemStack.getDisplayName();
	Itemname = StringUtils.removeEnd(Itemname, " Sample");

	Object Itemmolecule = null;
	String moleculesinitem = null;

	if(Config.Blockmolecules.get(Itemname) != null){
		Itemmolecule = Config.Blockmolecules.get(Itemname);
		moleculesinitem = Itemmolecule.toString();
	}

	if(ExtendedPlayer.IsResearched(Itemname)){
		if(Config.Blockmolecules.get(Itemname) != null){
			par3List.add( "This Sample consists of: " + Itemmolecule );
			if(moleculesinitem.contains(",")){
				String[] splitmolecule = moleculesinitem.split(",");
				for( int i = 0; i <= splitmolecule.length - 1; i++){
					par3List.add(Config.Moleculesatoms.get(splitmolecule[i]));
				}
			}else{
				par3List.add(Config.Moleculesatoms.get(Itemmolecule));
			}
		}
	}else{
		par3List.add("You have not yet researched this sample");
	}
}
}

Ah okay thanks.

 

1 more question is metadata still viable? since minecraft doesn't have ids anymore.

It could still be usefull for registering 5 items that are nearly the same like logs.
