[1.7.2] Store nbt data.[SOLVED]

Recommended Posts

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!

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

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.
