Hello i'm trying to create a Custim item extending AxeItem and editing its attackdamage when breaking a block.

1. what method is the best to use in this case ?

2. how do i get the Custom item from an ItemStack?

3. how can i give the Player the modified item ?

 

I'm currently using forge 1.16.5. 

so i got this: 

 

@Override
	public Multimap<Attribute, AttributeModifier> getAttributeModifiers(EquipmentSlotType slot, ItemStack stack) {
		
		return super.getAttributeModifiers(slot, stack);
	}

	@Override
	public boolean mineBlock(ItemStack item, World w, BlockState state, BlockPos pos, LivingEntity entity) {
		PlayerEntity p = (PlayerEntity) entity;
		p.sendMessage(new StringTextComponent("test"), p.getUUID());
		return super.mineBlock(item, w, state, pos, entity);
	}

 

but how do i change the damage and the tooltip ?

Edit: i mean the attackdamage

return a map that contains the attribute modifiers that you are going to add to the weapon (check SwordItem), but instead of create a constant one you want to add the modifiers dynamically (based on the stack's nbt tag) in the method getAttributeModifiers.

Override addInformation to add tooltips.

Do you have an code example i have no idea how to exactly do this 

can anyone give me an example? I dont find any examples elsewhere.

I got those methods: 

	@Override
	public Multimap<Attribute, AttributeModifier> getAttributeModifiers(EquipmentSlotType slot, ItemStack stack) {
		
		
		return super.getAttributeModifiers(slot, stack);
	}

	@Override
	public boolean mineBlock(ItemStack item, World w, BlockState state, BlockPos pos, LivingEntity entity) {
		PlayerEntity p = (PlayerEntity) entity;
		p.sendMessage(new StringTextComponent("test"), p.getUUID());
		return super.mineBlock(item, w, state, pos, entity);
	}

but i have no idea how to set a AttributeModifier 

I looked it up but i didnt get how to get an Attribute the Method: stack.addAttributeModifier(Attribute., AttributeModifier, slot);

asks for an Attribute. 

and if that makes a difference my item class extends aceItem

Yea i know but how do i convert the uuid of the attribute to a Attribute object ?

this ?:

 ToolItem(float p_i48512_1_, float p_i48512_2_, IItemTier p_i48512_3_, java.util.Set<Block> p_i48512_4_, Item.Properties p_i48512_5_)

do you mean this: ?

 

Constructor Detail

ToolItem

protected ToolItem(float attackDamageIn, float attackSpeedIn, IItemTier tier, java.util.Set<Block> effectiveBlocksIn, Item.Properties builder)

 

i font know hat you mean can you please send me a link or something ?

where can i find this ?

 

alright got it. now i got this: 

@Override
	public Multimap<Attribute, AttributeModifier> getAttributeModifiers(EquipmentSlotType slot, ItemStack stack) {
	    stack.addAttributeModifier(Attributes.ATTACK_DAMAGE, new AttributeModifier(BASE_ATTACK_DAMAGE_UUID, "new", minedBlocks*0.2, AttributeModifier.Operation.ADDITION), slot);
	    return super.getAttributeModifiers(slot, stack);
	}

but why can you no longer see the item properties like dmage when you hover over the item ingame ?

now i got this: 

	@Override
	public Multimap<Attribute, AttributeModifier> getAttributeModifiers(EquipmentSlotType slot, ItemStack stack) {
		Multimap<Attribute, AttributeModifier> modifiers = super.getAttributeModifiers(slot, stack);
		modifiers.put(Attributes.ATTACK_DAMAGE, new AttributeModifier(BASE_ATTACK_DAMAGE_UUID, "Tool modifier", minedBlocks*0.2, 	AttributeModifier.Operation.ADDITION));
	    return modifiers;
	}

but this throws an "java.lang.UnsupportedOperationException". 

 

like this ?

@Override
	public Multimap<Attribute, AttributeModifier> getAttributeModifiers(EquipmentSlotType slot, ItemStack stack) {
		Builder<Attribute, AttributeModifier> builder = ImmutableMultimap.builder();
		builder.put(Attributes.ATTACK_DAMAGE, new AttributeModifier(BASE_ATTACK_DAMAGE_UUID, "Tool modifier", minedBlocks*0.2, AttributeModifier.Operation.ADDITION));
		return builder.build();
	}

 

no i want to keep the base stats and just modify them. 

I tried this: 

@Override
	public Multimap<Attribute, AttributeModifier> getAttributeModifiers(EquipmentSlotType slot, ItemStack stack) {
		Builder<Attribute, AttributeModifier> builder = ImmutableMultimap.builder();
		builder.putAll(super.getAttributeModifiers(slot, stack));
		builder.put(Attributes.ATTACK_DAMAGE, new AttributeModifier(BASE_ATTACK_DAMAGE_UUID, "Tool modifier", minedBlocks*0.2, AttributeModifier.Operation.ADDITION));
		return builder.build();
	}

 

but if you hover over the item ingame you are not able to see the damage and attackspeed

yes it is called.
