I am working on a block that when placed in a custom machine can allow the player to select blocks to change how the block acts in the world. My issue is how i would be able to get the block to store the chosen blocks. I have a tile entiry for the block for when it is placed and what not. Do i use nbt or some other method. Any help is welcome

If I understand correctly - you know how to store data in world - as TileEntity, but you don't know how to store data when block is held - as ItemStack?

 

Well - yes, you can simply store NBT inside ItemStack. Just note that they will not stack or something.

 

As to how to exhange that data between TileEntity and ItemStack - you use various methods inside your Block class - you override method of placing to get NBT from ItemStack and transfer it to TileEntity placed and other way around using breakBlock (or something...).

1.7.10 is no longer supported by forge, you are on your own.

Override Block#getDrops to create an ItemStack with the appropriate NBT for the existing TileEntity (the TE will still be intact at the time this method is called).

 

Override Block#onBlockPlacedBy to read information from the ItemStack NBT and set it for the TileEntity (which has already been created for you by this point).

The 

TileEntity

isn't usually intact when 

Block#getDrops

is called, look at Forge's patch to 

BlockFlowerPot

to see how it delays the removal of the 

TileEntity

until after 

Block#getDrops

has been called.

Isn't there a damage to drop method that we can override?

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

Block#damageDropped

is called from 

Block#getDrops

, so the 

TileEntity

won't be intact when it's called unless you delay its removal. This method doesn't have 

World

or position arguments, so you can't use the 

TileEntity

anyway.

      Getting Holder<Enchantment> from RegistryKey in GLM

      By Orichalcum · Posted

      I know that this may be a basic question, but I am very new to modding. I am trying to have it so that I can create modified Vanilla loot tables that use a custom enchantment as a condition (i.e. enchantment present = item). However, I am having trouble trying to implement this; the LootItemRandomChanceWithEnchantedBonusCondition constructor needs a Holder<Enchantment> and I am unable to use the getOrThrow() method on the custom enchantment declared in my mod's enchantments class. Here is what I have so far in the GLM:   protected void start(HolderLookup.Provider registries) { HolderLookup.RegistryLookup<Enchantment> registrylookup = registries.lookupOrThrow(Registries.ENCHANTMENT); LootItemRandomChanceWithEnchantedBonusCondition lootItemRandomChanceWithEnchantedBonusCondition = new LootItemRandomChanceWithEnchantedBonusCondition(0.0f, LevelBasedValue.perLevel(0.07f), registrylookup.getOrThrow(*enchantment here*)); this.add("nebu_from_deepslate", new AddItemModifier(new LootItemCondition[]{ LootItemBlockStatePropertyCondition.hasBlockStateProperties(Blocks.DEEPSLATE).build(), LootItemRandomChanceCondition.randomChance(0.25f).build(), lootItemRandomChanceWithEnchantedBonusCondition }, OrichalcumItems.NEBU.get())); }   Inserting Enchantments.[vanilla enchantment here] actually works but trying to declare an enchantment from my custom enchantments class as [mod enchantment class].[custom enchantment] does not work even though they are both a ResourceKey and are registered in Registries.ENCHANTMENT. Basically, how would I go about making it so that a custom enchantment declared as a ResourceKey<Enchantment> of value ResourceKey.create(Registries.ENCHANTMENT, ResourceLocation.fromNamespaceAndPath([modid], [name])), declared in a seperate enchantments class, can be used in the LootItemRandomChanceWithEnchantedBonusCondition constructor as a Holder? I can't use getOrThrow() because there is no level or block entity/entity in the start() method and it is running as datagen. It's driving me nuts.

      Help resolving the root cause for Exception: Item id not set

      By socrates3992 · Posted

      Hi here is an update. I was able to fix the code so my mod does not crash Minecraft. Please understand that I am new to modding but I honestly am having a hard time understanding how anyone can get this to work without having extensive programming and debugging experience as well as searching across the Internet, multiple gen AI bots (claude, grok, openai), and examining source code hidden in the gradle directory and in various github repositories. I guess I am wrong because clearly there are thousands of mods so maybe I am just a newbie. Ok, rant over, here is a step by step summary so others can save the 3 days it took me to figure this out.   1. First, I am using forge 54.1.0 and Minecraft 1.21.4 2. I am creating a mod to add a shotgun to Minecraft 3. After creating the mod and compiling it, I installed the .jar file to the proper directory in Minecraft and used 1.21.4-forge-54.1.0 4. The mod immediately crashed with the error: Caused by: java.lang.NullPointerException: Item id not set 5. Using the stack trace, I determined that the Exception was being thrown from the net.minecraft.world.item.Item.Properties class 6. It seems that there are no javadocs for this class, so I used IntelliJ which was able to provide a decompiled version of the class, which I then examined to see the source of the error. Side question: Are there javadocs? 7. This method, specifically, was the culprit: protected String effectiveDescriptionId() {      return this.descriptionId.get(Objects.requireNonNull(this.id, "Item id not set"));  } 8. Now my quest was to determine how to set this.id. Looking at the same source file, I determined there was another method:  public Item.Properties setId(ResourceKey<Item> pId) {             this.id = pId;             return this;   } 9. So now, I need to figure out how to call setId(). This required working backwards a bit. Starting from the constructor, I stubbed out the variable p which is of type Item.Properties public static final RegistryObject<Item> SHOTGUN = ITEMS.register("shotgun", () -> new ShotgunItem(p)); Rather than putting this all on one line, I split it up for readability like this: private static final Item.Properties p = new Item.Properties().useItemDescriptionPrefix().setId(rk); Here is was the missing function, setId(), which takes a type of ResourceKey<Item>. My next problem is that due to the apparent lack of documentation (I tried searching the docs on this site) I could not determine the full import path to ResourceKey. I did some random searching on the Internet and stumbled across a Github repository which gave two clues: import net.minecraft.resources.ResourceKey; import net.minecraft.resources.ResourceLocation; Then I created the rk variable like this: private static ResourceKey<Item> rk = ResourceKey.create(Registries.ITEM, ResourceLocation.parse("modid:shotgunmod")); And now putting it all together in order: private static ResourceKey<Item> rk = ResourceKey.create(Registries.ITEM, ResourceLocation.parse("modid:shotgunmod")); private static final Item.Properties p = new Item.Properties().useItemDescriptionPrefix().setId(rk); public static final RegistryObject<Item> SHOTGUN = ITEMS.register("shotgun", () -> new ShotgunItem(p)); This compiled and the mod no longer crashes. I still have more to do on it, but hopefully this will save someone hours. I welcome any feedback and if I missed some obvious modding resource or tutorial that has this information. If not, I might suggest we add it somewhere for people trying to write a mod that doesn't crash. Thank you !!!

      Help resolving the root cause for Exception: Item id not set

      By socrates3992 · Posted

      I will keep adding to this thread with more information in case anyone can help, or at the very least I can keep my troubleshooting organized. I decided to downgrade to 54.1.0 in the hopes that this would fix the issue but it didn't. At least now I am on a "recommended" version. The crash report did confirm my earlier post that the Exception is coming from effectiveDescriptionId(). I'll continue to see if I can find a way to set the ID manually.   Caused by: java.lang.NullPointerException: Item id not set         at java.base/java.util.Objects.requireNonNull(Objects.java:259) ~[?:?]         at TRANSFORMER/[email protected]/net.minecraft.world.item.Item$Properties.effectiveDescriptionId(Item.java:465) ~[forge-1.21.4-54.1.0-client.jar!/:?]         at TRANSFORMER/[email protected]/net.minecraft.world.item.Item.<init>(Item.java:111) ~[forge-1.21.4-54.1.0-client.jar!/:?]         at TRANSFORMER/[email protected]/com.example.shotgunmod.ShotgunItem.<init>(ShotgunItem.java:19) ~[shotgunmod-1.0.0.jar!/:1.0.0]         at TRANSFORMER/[email protected]/com.example.shotgunmod.ModItems.lambda$static$0(ModItems.java:15) ~[shotgunmod-1.0.0.jar!/:1.0.0]         at TRANSFORMER/[email protected]/net.minecraftforge.registries.DeferredRegister$EventDispatcher.lambda$handleEvent
