How to save position of 2D images from instantiate?

HappyGamer3194

So, I am making a game similar to the game called 'Idle Balls', how do I store the position of all the ball image gameobjects so that when the player closes and reopens the app, the balls are still there? The balls are a 2D image with the 2D rigidbody component and are instantiated from an original image of the ball. Any help is greatly appreciated. I tried using playerprefs but it would be time consuming to make a playerpref for each axis and position of each of the balls, especially if there were hundreds of balls. I would appreciate links and samples of code if applicable.

This game has been cancelled.

It actually isnt as time consuming as you think.

Just add a script to the ball prefab you are instantiating the add these methods

void Load() //this goes in the start method

{

if(PlayerPrefs.GetFloat("x")!=null)

{

transform.position = new Vector2(PlayerPrefs.GetFloat("x"), PlayerPrefs.GetFloat("y"));

}

}

void save() // this goes in the Update method

{

PlayerPrefs.SetFloat("x", transform.position.x);

PlayerPrefs.SetFloat("y", transform.position.y);

}

It is not working for me... is this script correct?

using UnityEngine;

public class Ball : MonoBehaviour

{

  public float xballcoords;

  public float yballcoords;

  void Start()

  {

    xballcoords = PlayerPrefs.GetFloat("x" + this.gameObject.name, 2.5f);

    yballcoords = PlayerPrefs.GetFloat("y" + this.gameObject.name, 5.5f);

    gameObject.transform.position = new Vector2(xballcoords, yballcoords);

  }

  void Update()

  {

    xballcoords = gameObject.transform.position.x;

    yballcoords = gameObject.transform.position.y;

    PlayerPrefs.SetFloat("x" + this.gameObject.name, xballcoords);

    PlayerPrefs.SetFloat("y" + this.gameObject.name, yballcoords);

  }

  void OnTriggerEnter2D(Collider2D other)

  {

    if (other.gameObject.tag == "DestroyBalls")

    {

      Destroy(gameObject);

    }

  }

}

It works. I just have no idea how to instantiate them at the awake function.
