Creating an item, that has the function of a shield?

[MikeZ]

Hi!

I want to make an Item, that if it's in your hand it's like a shield (less damage).

Please give me some tips for that.

 

Thanks,

Mike

Check if the player is holding the shield, then use LivingHurtEvent to lower damage taken.

Thanks for your answer

At the moment I'm learning Java so i need some more help

Could you say me, how I can check if the player is holding the item?

 

Thanks,

Mike

Ok, thanks.

My code should like this:

If player.getCurrentEquippedItem() == OwnItem {

(How can I use the LivingHurtEvent to reduce dthe damage?)

 

Thanks,

Mike

Here is an example well it will add potion effect ressisstence for some seconds when you are holding the specific item.The seconds will not decrease until you dont have that specific item in hand

Its using ClientTickHandler

 

see here how to make 1. 

 

In the video he is using server proxy if you are using client proxy change do it in client proxy.

 

Then in TickHandler Class add this

 

package com.Flockshot.UltraDaimond.Proxy;

import java.util.EnumSet;

import net.minecraft.block.Block;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.potion.Potion;
import net.minecraft.potion.PotionEffect;
import net.minecraft.world.World;
import cpw.mods.fml.common.ITickHandler;
import cpw.mods.fml.common.TickType;

public class ClientTickHandler implements ITickHandler {

@Override
public void tickStart(EnumSet<TickType> type, Object... tickData) {

if(type.equals(EnumSet.of(TickType.PLAYER)))
{

	onPlayerTick((EntityPlayer) tickData[0]);

}

@Override
public void tickEnd(EnumSet<TickType> type, Object... tickData) {


}

@Override
public EnumSet<TickType> ticks() {

	return EnumSet.of(TickType.PLAYER, TickType.CLIENT);

}


@Override
public String getLabel() {

	return null;
}


private void onPlayerTick(EntityPlayer player){

	if(player.getCurrentItemOrArmor(0) != null){

		ItemStack hand = player.getCurrentItemOrArmor(0);

		if(hand.getItem() == Your item here ){ //Your item here

			player.addPotionEffect(new PotionEffect(Potion.resistance.getId(), 10, 0 ) );

		}



	}

}



}

@Override

if(type.equals(EnumSet.of(TickType.PLAYER)))
{

	onPlayerTick((EntityPlayer) tickData[0]);

}

@Override
public void tickEnd(EnumSet<TickType> type, Object... tickData) {


}

@Override
public EnumSet<TickType> ticks() {

	return EnumSet.of(TickType.PLAYER, TickType.CLIENT);

private void onPlayerTick(EntityPlayer player){

		ItemStack hand = player.getCurrentItemOrArmor(0);

		if(hand.getItem() == Your item here ){ //Your item here

			player.addPotionEffect(new PotionEffect(Potion.resistance.getId(), 10, 0 ) );

		}



	}

}



}

 

Ok, I added the code. But, if I hold the Item in my hand the potion effect is displayed but it has no effect

An if the potion effect is at 0 there is always the displayed potioneffec with duration 0

 

What should I do?

Either use the event as coolboy suggested, there is a tutorial on the wiki, or override Item#onUpdate(ItemStack, World, Entity, int, boolean) in your item.

The PotionEffect isn't going to work if you keep it on the client.
