Pass a GameObject to a DLL

Questions & Answers
1

Hey,I have a DLL that I use to save the player’s position, but when passing the parameters I can only pass Floats created by me, but I want to pass the entire GameObject to the DLL.
This is my code in the DLL;

using System;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

namespace SaveXML
{
    public class MyXML
    {

        public void Save(float lx, float ly, float lz)
        {
            XmlDocument xmlDoc = new XmlDocument();
            XmlNode rootNode;
            string filename = "MiPrimerXML.xml";

            if (System.IO.File.Exists(filename))
            {
                xmlDoc.Load(filename);
                rootNode = xmlDoc.SelectSingleNode("Game");
            }
            else
            {
                rootNode = xmlDoc.CreateElement("Game");
                xmlDoc.AppendChild(rootNode);
            }

            XmlNode userNode = xmlDoc.CreateElement("GameObject");
            XmlAttribute attribute = xmlDoc.CreateAttribute("name");
            attribute.Value = "Player";
            userNode.Attributes.Append(attribute);
            rootNode.AppendChild(userNode);

            XmlNode Vector = xmlDoc.CreateElement("Vector");
            XmlAttribute x = xmlDoc.CreateAttribute("X");
            x.Value = lx.ToString();
            XmlAttribute y = xmlDoc.CreateAttribute("Y");
            y.Value = ly.ToString();
            XmlAttribute z = xmlDoc.CreateAttribute("Z");
            z.Value = lz.ToString();

            Vector.Attributes.Append(x);
            Vector.Attributes.Append(y);
            Vector.Attributes.Append(z);
            userNode.AppendChild(Vector);

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Encoding = new UTF8Encoding(false); // Falso = no escribir BOM
            settings.Indent = true;
            XmlWriter writer = XmlTextWriter.Create(filename, settings);
            xmlDoc.Save(writer);
        }
    }
}

And this is my code in Unity

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using SaveXML;
public class Save : MonoBehaviour
{
    private SaveXML.MyXML savedll;
    private GameObject Jugador;
    // Start is called before the first frame update
    void Start()
    {
        savedll = new MyXML();
        Jugador = GameObject.FindGameObjectWithTag("Player");
    }

    // Update is called once per frame
    public void SaveXML()
    {
        float x = Jugador.transform.position.x;
        float y = Jugador.transform.position.y;
        float z = Jugador.transform.position.z;
        savedll.Save(x, y, z);
    }
}

Hello, you should probably rewrite the question because it has nothing to do with DLL, you are asking if it is posible to serialize a GameObject and the simple answer is no, you cant serialize a full gameobject that would require serializing all the componentes and even meshes, what you can serialize are your own classes llike a class Player with your needed properties

I found the solution, I had to export the Dll called UnityEngine.CoreModule.dll.
And I just had to create a GameObject as if it were in Unity itself.
