How do i make a custom enchant

I have looked everywhere but i cant find anything that is usefull that can help me

 

I don't think anyone wants to sit here and explain every process of making a custom enchant, but I will because I'm nice enough to do that!!!!!!! :smile:


First step is to register your own enchantment.
This is how I did it to keep things organized!

1. Create Main class and CustomEnchantment class!

PHP:


use pocketmine\plugin\PluginBase;
// We'll use these later
use pocketmine\item\Item;
use pocketmine\nbt\NBT;
use pocketmine\utils\TextFormat as C;
use pocketmine\command\{
    Command, CommandSender, ConsoleCommandSender
};
use pocketmine\item\enchantment\{
    Enchantment, EnchantmentInstance
};
use pocketmine\nbt\tag\{
    CompoundTag, ShortTag, ListTag
};

class Main extends PluginBase{

    public function onEnable(): void{
        new CustomEnchantment();
}


Then go to CustomEnchantment.php file you created.

PHP:

use pocketmine\item\enchantment\Enchantment;
use HealthStealer;

class CustomEnchantment {

    public const HEALTHSTEALER = 100; // Enchant ID
    // repeat with different number to create more enchants

    public function __construct(){
        $this->init();
    }
  
    public function init(){
        Enchantment::registerEnchantment(new Enchantment(self::HEALTHSTEALER, "Health Stealer", Enchantment::RARITY_COMMON, Enchantment::SLOT_SWORD, Enchantment::SLOT_NONE, 5));
        new HealthStealer();
        // repeat. I'm pretty sure you know what to do now.
    }
}


Then create a file named HealthStealer.php which will work as our listener.

PHP:

use pocketmine\Player;
use pocketmine\event\Listener;
use pocketmine\event\entity\{
    EntityDamageEvent, EntityDamageByEntityEvent
};

use MainClass;

class HealthStealer implements Listener {

    public function __construct() {
        MainClass::get()->getServer()->getPluginManager()->registerEvents($this, MainClass::get());
    }

    public function onDamage(EntityDamageEvent $event): void {
        if($event instanceof EntityDamageByEntityEvent){
            $damager = $event->getDamager();
            $entity = $event->getEntity();

            if($event->isCancelled()) return; // Prevent CE working even when on attack cooldown.
            if($damager->getInventory()->getItemInHand()->getEnchantment(100)) { // Checks for the enchantment
                $chance = rand(1, 200); // You can add a simple activation chance using this!
                if ($chance === 198) { // You can add a simple activation chance using this!
                    $damager->setHealth($damager->getHealth() + 5 > $damager->getMaxHealth() ? $damager->getMaxHealth() : $damager->getHealth() + 5);
                    $damager->sendMessage("§7>> §cYou stole health from ".$entity->getName()."!");
                }
            }
        }
    }
}


Now let's display those enchantments!

Back to your main file!

PHP:

  
    public function onCommand(CommandSender $sender, Command $cmd, string $label, array $args): bool{
        if($cmd->getName() == "customenchant"){
            if(count($args) < 2){
                $sender->sendMessage("Usage: /ceenchant <player> <enchantment> <level>");
                return false;
            }
            if(!$this->getServer()->getPlayer($args[0])){
                $sender->sendMessage("Player ". $args[0] . " cannot be found.");
                return false;
            }
            $player = $this->getServer()->getPlayer($args[0]);
            $inv = $player->getInventory();

            if($inv->getItemInHand() === null){
                $player->sendMessage("You must hold an item to proceed.");
                $sender->sendMessage($player->getName() . " Is not holding an item!");
                return false;
            }
            if(is_numeric($args[1])){
                $enchantment = Enchantment::getEnchantment((int) $args[1]);
            }else{
                $enchantment = Enchantment::getEnchantmentByName($args[1]);
            }
            if($args[1] < 100 || !$enchantment instanceof Enchantment){
                $sender->sendMessage("That enchantment cannot be found.");
                return false;
            }

            $item = $inv->getItemInHand();
            $this->addEnchantment($item, new EnchantmentInstance($enchantment, (int) ($args[2] ?? 1)), $enchantment);
            $inv->setItemInHand($item);
        }
    }
    public function addEnchantment(Item $item, EnchantmentInstance $enchantment, Enchantment $e): void{
        if($item->hasEnchantment($enchantment->getId())){
            $lvl = $item->getEnchantment($enchantment->getId())->getLevel();
            $lore = $item->getLore();
            $name = array_search($e->getName() . " " . $lvl, $lore);
            unset($lore[$name]);
            $item->setLore($lore);
            $item->removeEnchantment($enchantment->getId());
        }

        $found = false;
        $ench = $item->getNamedTagEntry(Item::TAG_ENCH);

        if(!($ench instanceof ListTag)){
            $ench = new ListTag(Item::TAG_ENCH, [], NBT::TAG_Compound);
        }else{
            foreach($ench as $k => $entry){
                if($entry->getShort("id") == $enchantment->getId()){
                    $nbt = new CompoundTag("", [
                        new ShortTag("id", $enchantment->getId()),
                        new ShortTag("lvl", $enchantment->getLevel())
                    ]);
                    $ench->set($k, $nbt);
                    $item->setLore(array_merge($item->getLore(), [$e->getName() . " " . $this->roman($enchantment->getLevel())]));
                    $found = true;
                    break;
                }
            }
        }

        if(!$found){
            $nbt = new CompoundTag("", [
                new ShortTag("id", $enchantment->getId()),
                new ShortTag("lvl", $enchantment->getLevel())
            ]);
            $ench->push($nbt);
            $item->setLore(array_merge($item->getLore(), [$e->getName() . " " . $this->roman($enchantment->getLevel())]));
        }
        $item->setNamedTagEntry($ench);
    }
  
  
    public function roman(int $lvl): string{
        $string = "";
        $romans = [
            "C" => 100,
            "L" => 50,
            "XL" => 40,
            "X" => 10,

        ];

        while($lvl > 0){

Simplest way to create custom enchant!

 

I love you

 

woww, you are amazing. I didn't know how to do it, thank you!

 

No problem guys!

 

There's one more, easier way
You can use PiggyCustomEnchant as an API

 

True, but it can be confusing for noob developers >:[

 

hello could you help me? I wanted to make a Custom Enchant Plugin, but for version 0.15.10 or 1.1.5, DaPiggyGuy's api is very complex so I wanted to know if you could explain it to me ( in the versions I mentioned the enchantment api is different :/ )

Why I use such an old version? Performance and still have a good amount of players playing lol

 

I have no clue of what API it had back then.
Mind sending me a link to it?

 

Yes i can https://drive.google.com/file/d/1GYeQVURcME5WdaHga0ymG001NPg1aKFC/view?usp=drivesdk

Note: As I want to learn how to make the plugin described above , this version which I use is a pmmp fork do you have any problem with that ? because I haven't found an official version of pmmp for 0.15.10

 

Could you upload this as a github repo? I want to read the files without having to download it..

 

and no. As long as I can understand what the version is doing, I can help you through!
If you have discord, please add me: minijaham#3259

 

What bro don't use this version.
Use the latest version of pocketmine. :
https://github.com/pmmp/Pocketmine-MP/releases

 

I think you mistaken with the plugin version. The plugin version is different of the API version.

 

Bro I described above why I'm using an old version

 

I sent the request to Discord, https://github.com/GenisysPro/GenisysPro esta é a api que estou usando no momento

 

Got it. Ill help you in a moment…Schools suck :/

 

nah relax, i understand

 

I cannot test if the method works, since I'm unable to get on the version of minecraft, but here.

Simply register the enchantment first:

PHP:

const TYPE_WEAPON_ENCHANTNAME;

Enchantment::registerEnchantment(self::TYPE_WEAPON_ENCHANTNAME, "Vampire", Enchantment::RARITY_COMMON, Enchantment::ACTIVATION_EQUIP, Enchantment::SLOT_SWORD);
new CustomEnchantName();


Then, implement the enchantment:

PHP:

class CustomEnchantName implements Listener {
    public function __construct() {
        MainClass::get()->getServer()->getPluginManager()->registerEvents($this, MainClass::get());
    }
    public function onDamage(EntityDamageEvent $event) : void { // the event can vary depending on what you're trying to do
        if($event instanceof EntityDamageByEntityEvent){
            // code
        }
    }
}


Now, when you're trying to enchant the custom enchant:

PHP:

if($item->hasEnchantment($enchantment->getId())) { // If the item has this enchantment
      $level = $item->getEnchantment($enchant)->getLevel();
      $lore = $item->getLore();
      $name = array_search($enchant->getName() . " " . $this->convert($level), $lore);
      unset($lore[$name]);
      $item->setLore($lore);
      $item->removeEnchantment($enchant);
   }
   $item->setLore(array_merge($item->getLore(), [$enchant->getName() . " " . $this->convert($enchantment->getLevel())]));
   }
    public function convert(int $lvl) : string // converts the enchantment level to roman numeral
    {
        $string = "";
        $romans = [
            'M' => 1000,
            'CM' => 900,
            'D' => 500,
            'CD' => 400,
            'C' => 100,
            'XC' => 90,
            'L' => 50,
            'XL' => 40,
            'X' => 10,
            'IX' => 9,
            'V' => 5,
            'IV' => 4,
            'I' => 1
        ];

        while($lvl > 0){
            foreach($romans as $roman => $int){
                if($lvl >= $int){
                    $lvl -= $int;
                    $string .= $roman;
                    break;
                }
            }
        }
        return $string;
    }


Do something like this. I can't really figure out how I can make this work in this version :l

perhaps,...someone else can continue with this and help?

 

You should be able to figure out how to do things now :l
Just follow the general structure I made
