Item attribute modifier API Library
Item Attribute API

This library offers you the opportunity to handle attribute modifiers on item stacks.

Background:
Attributes are properties of mobs and players ( http://minecraft.gamepedia.com/Attribute).
These attributes can be modified ( http://minecraft.gamepedia.com/Attribute#Modifiers).
These attribut modifiers can be deposited on items ( http://minecraft.gamepedia.com/Player.dat_format#Attribute_Modifiers).
This library allows to handle such modifiers on items.

Features:
For a detailed description of attributes and their modifiers see the MC wiki (Links above)

How to use:
This is not a plugin. Don't paste it into a plugins folder of a MC server.
Download the JAR and import it into your IDE.
How to Import a external library in Eclipse -> TUTORIAL
Code (Java):
import minecraft.spigot.community.michel_0.api.Attribute ;
import minecraft.spigot.community.michel_0.api.AttributeModifier ;
import minecraft.spigot.community.michel_0.api.ItemAttributes ;
import minecraft.spigot.community.michel_0.api.Slot ;

ItemStack item = /* ...some item you want to modify... */ ;

// First you need a new instance of ItemAttributes
ItemAttributes attributeModifiers = new ItemAttributes ( ) ;

// Then you need to define your modifiers
AttributeModifier speedModifier = new AttributeModifier ( Attribute. MOVEMENT_SPEED, "AdditionalSpeed", Slot. MAIN_HAND, 0, 1.0d, UUID. randomUUID ( ) ) ;
AttributeModifier attackModifier = new AttributeModifier ( Attribute. ATTACK_DAMAGE, "AdditionalDamage", Slot. MAIN_HAND, 0, 4.0d, UUID. randomUUID ( ) ) ;

// Next is to add these modifiers to the attribut modifiers set
attributeModifiers. addModifier (speedModifier ) ;
attributeModifiers. addModifier (attackModifier ) ;

// Finally apply it on a item stack
item = attributeModifiers. apply (item ) ;
