Title: Polymorph for Admin
Post by: BazookaRpm on June 02, 2025, 08:05:58 PM

Hi friends, I'm sharing this code that the administrator can use to change the appearance of a mob based on its ID.

Motivated to continue collaborating with free tier users.

The admin command can change your appearance to show it to other players.
For example: you use the following admin command //polymorph 29022
where the ID: 29022 corresponds to Zaken, then all other players will see you as Zaken, the same if you apply the ID: 25286 everyone will see you as the raid boss Anakim

First we are going to create two new methods in Java in the following path.
Route : dist\game\data\scripts\handlers\admincommandhandlers\AdminPolymorph.java
below is the code we will create.

return true;

Next we will add the following codes.We will update charInfo to show us the polymorph

Code: [Select]

// client radar
// TODO: This needs to be better integrated and saved/loaded
private final Radar _radar;

// polymorph
private final ObjectPoly _poly = new ObjectPoly(this);
also add in the same player.java

Code: [Select]

public ContactList getContactList()
{
return _contactList;
}

public ObjectPoly getPoly()  // polymorph test
{
    return _poly;
}

public boolean isPolymorphed()  // polymorph test

}

public String getPolyType()   // polymorph test
{
    return _poly.getPolyType();
}

public int getPolyId()
{
    return _poly.getPolyId(); // polymorph test
}

finally in WorldObjet.java
add.

Code: [Select]

import org.l2jmobius.gameserver.network.serverpackets.ServerPacket;
import org.l2jmobius.gameserver.model.actor.poly.ObjectPoly;


Code: [Select]
