Hey guys,

I'm working on a big mod here, wrote about 10 custom mobs, 10 custom blocks, but when the items occur, i get stuck

I want to give a player a custom written book with some pages of text in it but I can't seem to get it working.

 

I've tried writing some NBT tags but that didn't seem to work (Or i messed up)

Is there a way to let the player get an item from the creative menu (so really a custom item) and when the rightclick executes, it opens up a hard-coded text?

the item itself is already added to the menu etc. but i want it to have the text in it...

 

can you guys help me out?

 

thanks

Well, you'd need to do the NBT data on the ItemStack correctly.

 

Unfortunately I cannot locate the documentation regarding this, but it would be available by looking at the WrittenBook item class.

i tried to, but it didn't seem to work for some reason so either i used the wrong method, OR i used the wrong tags, OR i messed up somewhere else... i tried an example from another mod [1.7] but the WrittenBook class is no longer a thing

I've tried the method of this classes: https://github.com/rockysims/fortressmod/tree/master/src/main/java/com/newyith/fortressmod/items but since they are form end-2014 i didn't expected much. so either i messed up somewhere, or this method doesnt work anymore.

(considering the fact that the WrittenBook.Class no longer exists )

this is my current item class:

package nl.JKCTech.fnaf.items;

import java.util.ArrayList;
import java.util.List;

import com.google.common.collect.Lists;

import net.minecraft.block.BlockContainer;
import net.minecraft.block.material.Material;

import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.StatCollector;
import net.minecraft.world.World;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

public class Manual extends ItemBook {

@SideOnly(Side.CLIENT)
    public boolean hasEffect(ItemStack stack)
    {
        return true;
    }

@Override
public void onUpdate(ItemStack itemstack, World world, Entity entity, int metadata, boolean bool)
{
	System.out.println("FIRED Update");
    if (itemstack.getTagCompound() == null)
    {
    	System.out.println("IF = Y");
    	itemstack.setTagCompound(new NBTTagCompound());
    	itemstack.getTagCompound().setString("author", "JKCTech");
     	itemstack.getTagCompound().setString("title", "Test");
    } else {
    	System.out.println("IF = N");
    }
}

public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
{
	System.out.println("FIRED onRIghtClick");
	par3EntityPlayer.displayGUIBook(par1ItemStack);
	return par1ItemStack;
}
}

 

i've added some debug stuff as well, when receiving the item, the console outputs:

 

when i right-click, the event also fires.

 

but just nothing happens...

i'm getting really confused.

 

i also checked the nbt data of both items, the data IS written, but it just doesn't get recognised as a book....

the only difference between the 2 is the item ID, and the fact my item doesn't contain pages (yet) since i don't exactly now how to do that... (Would also be of help)

Its not recognized as a written book because it's not an ItemWritableBook.

do you mean it has to be the exact item? because i tried to extend the ItemWritableBook Class but still the same result, and if it has to be the ItemWritableBook item, how do i create a custom dupe?

You can just create a new ItemStack of the ItemWritableBook instance (check the

Items

list) and apply the correct NBT tags.

 

You can now clone and distribute this itemstack however.
