Solved Enchantment Glow !

Hi,

How would I put enchantment glow on a item without having to enchant it ?

Any help is appreciated

Best wishes - Jace_OiO ​

 

You can use NBT to add the "ench" tag to the item, but this is not recommanded, there is also a way using ProtocolLib, but for BackPacks++ I just created a new Enchantment that does nothing...

 

CaptainBern Thanks for the quik answer

But, how would you create a Enchantment that does nothing ..?

- Best wishes Jace_OiO

 

In BackPacks++ I did it like this:

Code:

try{
try {
Field f = Enchantment.class.getDeclaredField("acceptingNew");
f.setAccessible(true);
f.set(null, true);
} catch (Exception e) {
e.printStackTrace();
}
//
try {
ench = new BPEnchantmentWrapper(69); //< this is your custom wrapper (a class that extends an EnchantmentWrapper with the needed stuff and returns, 69 is the id I choosed (lawl)
EnchantmentWrapper.registerEnchantment(ench); //<this is used to register the enchantment.
} catch (IllegalArgumentException e){
 
}
}catch(Exception e){
e.printStackTrace();
}

 

CaptainBern - thanks alot for the code :=)

So basicly after I wrote this code I could create a itemstack and do
item.addEnchantment(ench, 2); ??

 

yes.

 

Cool, thanks ill just try it out

CaptainBern Would would be needed in the BPEnchantmentWrapper class ?

You can change the name but it's imprtant you let it extend EnchantmentWrapper and then add the methods it says...In my case that looked like this:

Code:

package me.captainbern.backpack.utils;
 
import org.bukkit.enchantments.Enchantment;
import org.bukkit.enchantments.EnchantmentTarget;
import org.bukkit.enchantments.EnchantmentWrapper;
import org.bukkit.inventory.ItemStack;
 
public class BPEnchantmentWrapper extends EnchantmentWrapper {
 
    public BPEnchantmentWrapper(int id) {
        super(id);
    }
   
    @Override
    public boolean canEnchantItem(ItemStack item) {
        return true;
    }
 
    @Override
    public boolean conflictsWith(Enchantment other) {
        return false;
    }
 
    @Override
    public EnchantmentTarget getItemTarget() {
        return null;
    }
 
    @Override
    public int getMaxLevel() {
        return 2;
    }
 
    @Override
    public String getName() {
        return "BackPack";
    }
 
    @Override
    public int getStartLevel() {
        return 1;
    }
}

 

Ok thanks,

time to test !

 

No problem! (Note: I think you still need to use addUnsafeEnchantment(); if you left the enchantmentTarget return null

 

CaptainBern
It gives me a red line under ench in ench = new BPEnchantmentWrapper(69);
Maybe I should do like this ?
BPEnchantmentWrapper ench = newBPEnchantmentWrapper(69);

 

Jace_oio If it says it can't be resolved to a variable then yes.

 

Oh yes, I did it like that because I made BPEnchantmentWrapper ench; a static that can be altered by Main.ench;

 

Okay well time to test XD

CaptainBern Im not getting the glow effect or any enchantment

Code:

ItemStack kit = new ItemStack(Material.BOOK);
        ItemMeta meta7 = kit.getItemMeta();
        try{
            try {
            java.lang.reflect.Field f = Enchantment.class.getDeclaredField("acceptingNew");
            f.setAccessible(true);
            f.set(null, true);
            } catch (Exception e) {
            e.printStackTrace();
            }
            //
            try {
            ench = new BPEnchantmentWrapper(69); //< this is your custom wrapper (a class that extends an EnchantmentWrapper with the needed stuff and returns, 69 is the id I choosed (lawl)
            EnchantmentWrapper.registerEnchantment(ench); //<this is used to register the enchantment.
            } catch (IllegalArgumentException e){
           
            }
            }catch(Exception e){
            e.printStackTrace();
            }
        meta7.setDisplayName(ChatColor.AQUA +  ""  + ChatColor.ITALIC +  "Diamond sword and full iron armor kit");
        lore14.add(lore13);
        meta7.setLore(lore14);
        kit.addUnsafeEnchantment(plugin.ench, 1);
        kit.setItemMeta(meta7);
        shop.addItem(kit);

and then
static BPEnchantmentWrapper ench; in the top

Jace_oio If you are just wanting to add a glow effect to the ItemStack then use this,

Code:

    public static ItemStack addGlow(ItemStack item) {
        net.minecraft.server.v1_5_R3.ItemStack nmsStack = CraftItemStack.asNMSCopy(item);
        NBTTagCompound tag = null;
        if (!nmsStack.hasTag()) {
            tag = new NBTTagCompound();
            nmsStack.setTag(tag);
        }
        if (tag == null)
            tag = nmsStack.getTag();
        NBTTagList ench = new NBTTagList();
        tag.set("ench", ench);
        nmsStack.setTag(tag);
        return CraftItemStack.asCraftMirror(nmsStack);
    }

 

Hmm, does it print any errors?

edit: Use the way GodOfMadness said, (I use my way to check if an item is a backpack)

 

Okay ill try it out

GodzOfMadness how would I use your code if I wanted enchantment glow on a book ?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Jace_oio The code I've given you should add the glow on the book.
EDIT:
The addGlow method returns an ItemStack so you would have to set the ItemStack that the addGlow method returns.

 

Ok Ill test

But how can I make sure its the book I wanna add into the shop ???

Jace_oio Which way do you want to check if it's the certain book? Through the DisplayName/Lore?
If so then just get the ItemMeta of the ItemStack before you use the addGlow method and if it doesn't equal null(same for lore) then compare to one another. If all the checks go well then use the addGlow method.

 

If you want to use NMS you can use this:

PHP:

public static ItemStack addGlow(ItemStack item) {
        net.minecraft.server.v1_5_R3.ItemStack nmsStack = null;
        CraftItemStack craftStack = null;
     
        if (item instanceof CraftItemStack)
            craftStack = (CraftItemStack) item;
        else
            craftStack = CraftItemStack.asCraftCopy(item);
     
        nmsStack = CraftItemStack.asNMSCopy(craftStack);
     
        NBTTagCompound tag = null;
        if (!nmsStack.hasTag()) return item;
        tag = nmsStack.getTag();
        tag.add("ench");
        nmsStack.setTag(tag);
     
        return CraftItemStack.asCraftMirror(nmsStack);
    }

Instead of 1.5.R3 you could use some reflection.

 

TheTinySpider thanks for the reply, what is NMS code ?? and how to use ?

EDIT: hehe im guesing its net minecraft server ?

 

Jace_oio NMS = net.minecraft.server

 

hehe thanks even though I figured it out

But still how do I use NMS code ?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Jace_oio You're using it if you still have that addGlow method that I've given you.

 

GodzOfMadness hehe XD but how would I use it in general ?

- every line of code is easyer to use if you know the meaning of it.

 

Jace_oio Here is the github for craftbukkit. You can always look through their classes and see how it works and how you can manipulate it. Like creating a custom entity. Like make a mob AI. You can say extend EntityZombie and takes it's methods and add/remove some of it's path finder goals to make it do what you want it to do.

 

You use it whenever you use an object or method that belongs to the 'net.minecraft.server' packages.

CraftPlayer, CraftWorld, etc. are methods of Craftbukkit, not bukkit. Bukkit alone can not do this

 

GodzOfMadness & TheGreenGamerHD Thanks for the usefull replies

CaptainBern, GodzOfMadness, TheTinySpider and TheGreenGamerHD
