Help to increase reach attack in version 1.18.2

[Sokoly_]

Hi, I've been testing ways to increase the reach attack of a tool, but I still haven't found a way to implement it properly. I'd like your help.

[Sokoly_]

Could you tell me if there is an erro

why did you not read the posts in the thread, like I told you (as a reminder here)?

first of all you need to add the ForgeMod.REACH_DISTANCE to all EntityTypes that you want to have your Attribute,
then you need to create a Multimap with the Attribute itself and it's AttributeModifier, note this map must be lazy initialized, you can use Lazy.of for this
and last but not least you need to return the Multimap in Item#getAttributeModifiers, if you want to add the Attribute to a vanilla Item you need to use ItemAttributeModifierEvent

    @SubscribeEvent
    public static void onEntityAttributeModificationEvent(final EntityAttributeModificationEvent event) {
		event.add(EntityType.PLAYER, ForgeMod.REACH_DISTANCE.get());
	}

this is correct now you need to remaingin stuff

In the old thread I saw this way of doing it, but I think there is something wrong, could you tell me the fault

    public final Lazy<Multimap<Attribute, AttributeModifier>> LAZY = Lazy.of(() ->  {    
    	ImmutableMultimap.Builder<Attribute, AttributeModifier> builder = ImmutableMultimap.builder(); 
    	 builder.put(Attributes.ATTACK_DAMAGE, new AttributeModifier(BASE_ATTACK_DAMAGE_UUID, "Weapon modifier", damage, AttributeModifier.Operation.ADDITION));
         builder.put(Attributes.ATTACK_SPEED, new AttributeModifier(BASE_ATTACK_SPEED_UUID, "Weapon modifier", speed, AttributeModifier.Operation.ADDITION));
         
         if (ForgeMod.REACH_DISTANCE.isPresent()) {
             builder.put(ForgeMod.REACH_DISTANCE.get(), new AttributeModifier(ATTACK_REACH_MODIFIER, "Weapon modifier", reach, AttributeModifier.Operation.ADDITION));
         }
         builder.put(Attributes.ATTACK_KNOCKBACK, new AttributeModifier(ATTACK_KNOCKBACK_MODIFIER, "Weapon modifier", kb, AttributeModifier.Operation.ADDITION));
    	Multimap<Attribute, AttributeModifier> attributeModifiers = ArrayListMultimap.create();
    	attributeModifiers = builder.build();
    	return attributeModifiers;
    });

this should work but there are a few unnecessary code lines:

    	Multimap<Attribute, AttributeModifier> attributeModifiers = ArrayListMultimap.create();
    	attributeModifiers = builder.build();
    	return attributeModifiers;

you can just return ImmutableMultimap.Builder#build

And what about the Packet Handler I was referring to this

this is not necessary, since the Forge REACH_DISTANCE is already synced between server and client

[Sokoly_]

Well I will try to test, if there is an error I will come back later

[Sokoly_]

I've been testing it and nothing has changed

[Sokoly_]

I've been testing and I already added the reach distance, but still you can't hit from a distance

Edited May 19, 2022 by Sokoly_

[Sokoly_]

Good morning, I have been testing and I have managed to put the Forge REACH DISTANCE on the tool, but it still does not hit from a distance

[Sokoly_]

Any idea why that happens?

[Luis_ST]

show your code

you didn't do what i told you to do, why did you copy the code from this thread?

So the " public static void mouseEvent(InputEvent.MouseInputEvent event)" is unnecessary?

So please could you give me an example of how to make it possible to hit from a distance. I have seen other mods on github and most have the same process and I can't find another

[Luis_ST]

do you know basic java?

No. I'm actually new to creating mods.

[Luis_ST]

basic java is required before modding minecraft
you can take a look at this:
