Your entity's getNameTag method must return a string

 

And this entity's getNameTag string() same or not my monster name string()？

 

Like this?
public function getName(): string{
return $this->getNameTag();
}

 

I try function :string is not useful

 

Idk how your class looks like, you'd need to send it here

 

And this mine entity zombie class , if need more class I can send.

PHP:

<?php

namespace pve\entity\monster\walking\WearableMonster;

use pocketmine\item\Item;
use pve\entity\monster\WearableMonster;

class AZombie extends WearableMonster{

 const NETWORK_ID = 32;

 public $width = 0.6;
 public $height = 1.8;
 public $eyeHeight = 1.62;
 
 public function getName() : string{
  return "Zombie";
 }
 
 public function getDrops() : array{
  if($this->rpg === []){
   switch(mt_rand(1, 3)){
    case 1:
    case 2: return [Item::get(367, 0, mt_rand(1, 3))];
    default: return [];
   }
  }else{
   return [];
  }
 }

}

 

I think it should be getNameTag, not getName

 

You mean like this?

PHP:

public function getNameTag() : string{
        return "Zombie";
    }

 

OK ！Thank you pay for time answer the mine question！I fix it ！And have a good time！

 

Or you can simply use the entity data value
