Guys, my english is very bad but whatever... Here's the thing, i want to make a new sword(done) that will do more damage against endermans, i tought to do that with EVENTS, when the player hits a mob it will check if the player is holding the correct item and if the target's a enderman... Until here everything is fine but how do I do damage to an entity and the damage must be like the player's hitting!! Here's my code:

 

MotherClass

package com.enderutilities.mainpackage;

import java.net.Proxy;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.item.Item;
import net.minecraft.util.DamageSource;
import net.minecraftforge.common.MinecraftForge;

import com.enderutilities.EnderBlocks.BlockRegistry;
import com.enderutilities.EnderBlocks.PlatinumOre;
import com.enderutilities.EnderItems.ItemRegistry;
import com.enderutilities.EnderTab.EnderTabs;
import com.enderutilities.OreSpawn.WGeneration;
import com.enderutilities.library.EnderStrings;

import cpw.mods.fml.common.FMLCommonHandler;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.SidedProxy;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;
import cpw.mods.fml.common.registry.GameRegistry;


@Mod(modid = EnderStrings.MODID, version = EnderStrings.VERSION, name = EnderStrings.NAME)
public class MotherClass 
{
@SidedProxy(clientSide = "com.enderutilities.mainpackage.ClientProxy", serverSide = "com.enderutilities.mainpackage.CommonProxy")
public static CommonProxy proxy;

//Pre-inicialiçao
@EventHandler
public static void preLoad(FMLPreInitializationEvent event)
{
	ItemRegistry.itemMain();
	BlockRegistry.blockMain();
	MinecraftForge.EVENT_BUS.register(new EventControl());
	GameRegistry.registerWorldGenerator(new WGeneration(), 0);
	proxy.registerRender();
}
//Inicialiçao
@EventHandler
public static void load(FMLInitializationEvent event)
{

}
//Pós-inicialiçao
@EventHandler
public static void postLoad(FMLPostInitializationEvent event)
{

}

 

EventClass( I don't think the others classes will be necessary for now)

package com.enderutilities.mainpackage;

import javax.xml.transform.Source;

import api.player.client.ClientPlayerAPI;
import api.player.client.ClientPlayerConstructorVisitor;
import api.player.client.IClientPlayerAPI;

import com.enderutilities.EnderItems.ItemRegistry;

import net.minecraft.client.entity.EntityPlayerSP;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.monster.EntityEnderman;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Items;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.DamageSource;
import net.minecraftforge.event.entity.living.LivingAttackEvent;
import net.minecraftforge.event.entity.player.AttackEntityEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;

public class EventControl{
@SubscribeEvent
public void hitEndermanWithDagger(AttackEntityEvent event)
{
	EntityPlayer player = event.entityPlayer;
	if(event.target instanceof EntityEnderman)
	{
		if(player.getCurrentEquippedItem().getItem() == ItemRegistry.platinumDagger)
		{
			//DONT KNOW HOW TO DEAL DAMAGE TO THE ENDERMAN, TRIED A LOT :'(
		}
	}
}
}

I didn't read your code, BUT:

You don't need events for CUSTOM things, events are to change vanilla behaviour.

If you have your own sword class (which I assume you do) you can override a method hitEntity(ItemStack stack, EntityLivingBase target, EntityLivingBase attacker).

 

Oh, and since that doesn't answer your main question, here it is:

 

target.attackEntityFrom(source, amount)

Thx for answer me, but there's the problem.. the "target.attackEntityFrom(source, amount)"... it asks for the source, i dont imagine what i've to put there since there's no Damagesource in the method hit entity

Damagesource is damagesource:

target.attackEntityFrom(DamageSource.fall, 10.0F);

 

This will deal 10 fall damage.

 

You can use vanilla damagesources or make your own.

Dude have you any idea of how much i love you at this moment? <3
