Saving/Loading an ItemStack to a NBTTagCompound?

Posted October 27, 201311 yr

Is there a way to store an ItemStack into an NBTTagCompound with a String key?

Yes.

ItemStack has a writeToNBT function. Just pass in a new NBTTagCompound and you'll get the "stored" version back out. Then just add that tag to another tag.

All container objects do this to save their contents.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Am I doing this right? It doesn't save/load the item stacks at all.

package net.gloriarpg.inventory;

import net.gloriarpg.GloriaRPG;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.inventory.IInventory;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;

public class InventoryAccessories implements IInventory
{

public ItemStack[] slots = new ItemStack[7];
public EntityPlayer player;

public InventoryAccessories(EntityPlayer player)
{

	this.player = player;

	this.loadInventoryFromNBT(player);

}

public void loadInventoryFromNBT(EntityPlayer player)
{

	NBTTagCompound nbt = player.getEntityData();

	for(int i = 0;i < slots.length; i++)
	{

		if(slots[i] != null)
		{

			slots[i].writeToNBT(nbt);

		}

	}

}

public void saveInventoryToNBTTagCompound(EntityPlayer player)
{

	NBTTagCompound nbt = player.getEntityData();

	for(int i = 0;i < slots.length; i++)
	{

		if(slots[i] != null)
		{

			slots[i].loadItemStackFromNBT(nbt);

		}

	}

}

@Override
public int getSizeInventory()
{

	return 7;

}

@Override
public ItemStack getStackInSlot(int i)
{

	return slots[i];

}

@Override
public ItemStack decrStackSize(int i, int j)
{

	return slots[i];

}

@Override
public ItemStack getStackInSlotOnClosing(int i)
{

	return slots[i];

}

@Override
public void setInventorySlotContents(int i, ItemStack itemStack)
{

	slots[i] = itemStack;

}

@Override
public String getInvName()
{

	return "Accessories";

}

@Override
public boolean isInvNameLocalized()
{

	return true;

}

@Override
public int getInventoryStackLimit()
{

	return 1;

}

@Override
public void onInventoryChanged()
{

	this.loadInventoryFromNBT(player);
	this.saveInventoryToNBTTagCompound(player);

}

@Override
public boolean isUseableByPlayer(EntityPlayer player)
{

	if(!player.isDead && !player.worldObj.isRemote)
	{

		return true;

	}

	return false;

}

@Override
public void openChest()
{

	//dunno

}

@Override
public void closeChest()
{

	//dunno

}

@Override
public boolean isItemValidForSlot(int i, ItemStack itemStack)
{

	return true;

}

}

Hello,

This might help you (it's from a TileEntity):

NBTTagList taglist = par1nbtTagCompound.getTagList("Inventory");

	for (int i = 0; i < taglist.tagCount(); i++)
	{
		NBTTagCompound tag = (NBTTagCompound)taglist.tagAt(i);

	    byte slot = tag.getByte("Slot");

	    if (slot >= 0 && slot < inventory.length)
	    {
	    	inventory[slot] = ItemStack.loadItemStackFromNBT(tag);
	    }
	}

And for writing:

NBTTagList itemlist = new NBTTagList();

	for (int i = 0; i < inventory.length; i++)
	{
		ItemStack itemstack = inventory[i];

	    if (itemstack != null)
	    {
	    	NBTTagCompound tag = new NBTTagCompound();

	        tag.setByte("Slot", (byte)i);
	        itemstack.writeToNBT(tag);
	        itemlist.appendTag(tag);
	    }
	}

For the writing part, how would I write that NBTTagList to the player's NBTTagCompound with a String?

How to add my mob to another mod's biome in 1.20.1.

You can add mob spawns using Forge's Biome Modifiers feature. I won't go into details on how to use a data generator for them, but here's a simple example:
{ "type": "forge:add_spawns", // Required "biomes": "#namespace:biome_tag", // Accepts a biome id, [list of biome ids], or #namespace:biome_tag "spawners": { "type": "namespace:entity_type", // Type of mob to spawn "weight": 100, // int, spawn weighting "minCount": 1, // int, minimum pack size "maxCount": 4 // int, maximum pack size } }This JSON file would go somewhere like this: data/modid/forge/biome_modifier/your_biome_modifier.json

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?
