[SOLVED][1.6.4]Helmet that adds Infinity to Items Help


Clawx207

Recommended Posts

As the title says, i am trying to make this item. Here's my current code for it:

 

 

public void onArmorTickUpdate(World world, EntityPlayer player, ItemStack item)

{

        if (player.getCurrentItemOrArmor(4) != null)

        {

            ItemStack helmet = player.getCurrentItemOrArmor(4);

            if (helmet.getItem() == this)

            {

            if(player.getCurrentEquippedItem().getItem() instanceof ItemBow)

            {

                player.getCurrentEquippedItem().addEnchantment(Enchantment.infinity, 1);

            }

            }

        }

}

 

 

It "Kind of works". As it keeps enchanting the bow to the point where it looks like this then crashes:

 

infinity I

infinity I

infinity I

infinity I

infinity I

infinity I

infinity I

 

 

How would i make it so it only enchants the item once?

if(!player.getCurrentEquippedItem().hasEnchantment(Enchantment.infinity, 1))
{
     player.getCurrentEquippedItem().addEnchantment(Enchantment.infinity, 1);
}

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

You will also need to find a way to remove the enchantment when they're no longer holding it.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.

if(!player.getCurrentEquippedItem().hasEnchantment(Enchantment.infinity, 1))
{
     player.getCurrentEquippedItem().addEnchantment(Enchantment.infinity, 1);
}

 

.hasEnchantment does not exist...?

 

 

Edit:

 

Ahhh but this works:

 

if(!player.getCurrentEquippedItem().hasEffect(Enchantment.infinity.effectId))

Tip:

There are multiple ways to get rid of an item so it's no longer your active one.

Tip #2:

One of them involves Item Frames.  An item that goes into a frame ceases to exist with no function calls or events.  So unless your plan is to let the player have infinite* free infinity bows, this is an idea that is doomed to failure.

Tip #3:

The helmet no longer being worn / ceasing to exist will also need to be covered.

 

*Pun not intended, but enjoyed.  And only "inifinite-until-helmet-breaks" of course.

This is my updated code:

 

 

public void onArmorTickUpdate(World world, EntityPlayer player, ItemStack item)

{

int i;

        if (player.getCurrentItemOrArmor(4) != null)

        {

            ItemStack helmet = player.getCurrentItemOrArmor(4);

            if (helmet.getItem() == this)

            {

            if(player.getCurrentEquippedItem().getItem() instanceof ItemBow)

            {

            if(!player.getCurrentEquippedItem().hasEffect(Enchantment.infinity.effectId))

            {

                player.getCurrentEquippedItem().addEnchantment(Enchantment.infinity, 1);

            }

            }

            }

        }

}

 

 

"if(player.getCurrentEquippedItem().getItem() instanceof ItemBow)" is the line of code it is having issues with

Haha! One up to you good sir!

 

Changed some things around here's what i'm going with for right now!

 

 

public void onArmorTickUpdate(World world, EntityPlayer player, ItemStack item)

{

ItemStack itemstack = player.getCurrentEquippedItem();

 

        if (player.getCurrentItemOrArmor(4) != null)

        {

            ItemStack helmet = player.getCurrentItemOrArmor(4);

            if (helmet.getItem() == this)

            {

            if(itemstack != null && itemstack.itemID == Item.bow.itemID)

            {

            if(!itemstack.hasEffect(Enchantment.infinity.effectId))

            {

            itemstack.addEnchantment(Enchantment.infinity, 1);

            }

            }

            }

        }

}

 

 

Thank you guys! Much more responsive than the minecraft forums!
