[1.15.2] How do I create a crafting recipe which damages an item?


superminerJG

Recommended Posts

I have three items involved: a sledgehammer, copper ore and copper dust.

When you craft the sledgehammer and the copper ore together (shapeless), it should give you copper dust.

However, the sledgehammer stays on the crafting grid and loses 1 durability.

 

Can this be done through JSON, or do I have to code it in to get it to work? If I do have to code it in, how?

Your hammer needs to overrhide hasContainerItem and getContainerItem. In the second take in the passed stack, tryDamage it, and return it.

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.

Look at the bucket. Yes it doesn't damage the item, but t does override the relevant method.

That might be the Forge bucket. Look for the MilkBucket.

However, do you have an example (maybe from an existing mod) that I can look at?

This should work:

@Override
public boolean hasContainerItem()
{
  return true;
}

@Override
public ItemStack getContainerItem(ItemStack itemStack)
{
  ItemStack stack = itemStack.copy();
  if(stack.attemptDamageItem(1, random, null))
  {
    stack.shrink(1);
    stack.setDamage(0);
  }
  return stack;
}

 

 

EDIT: And of course set the max damage in your item's properties. (maxDamage)

Please don’t post copy-pasta code like this in the future. Others will just copy it without learning anything.

Some tips:

Spoiler

Modder Support:

Spoiler

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

4.

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:

Spoiler

1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

I totally agree with you. I thought in this case it's fine because the code isn't complex at all and there is no real vanilla reference to look at. ^^

Why not just return a copy of ItemStack.EMPTY instead of setting count to zero and resetting damage?

Functionally an itemstack with a size of zero is the same as an empty stack. So do what you like.

    • They were already updated, and just to double check I even did a cleanup and fresh update from that same page. I'm quite sure drivers are not the problem here. 
    • i tried downloading the drivers but it says no AMD graphics hardware has been detected    
    • Update your AMD/ATI drivers - get the drivers from their website - do not update via system  
    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
