Problem with startPos

Hi there
I'm still a beginner in unity and need help. My problem is I want to restart my objects when they collide with another object but it only restarts one object. The CharacterCreation is there for me that I can change the characters at the button. My problem is that the characters are all in a different position when it comes to the start position. Here are my scripts.
Sorry for my bad english
Thx

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class BallController : MonoBehaviour
{
public Rigidbody rb;
private Vector3 startPos;
public float impulseForce = 5f;

// Use this for initialization
void Awake()
{
startPos = transform.position;
}

private void OnCollisionEnter(Collision other)

{
if (!other.transform.GetComponent<Goal>())
{
/*foreach (Transform t in other.transform.parent)
{
gameObject.AddComponent<TriangleExplosion>();

StartCoroutine(gameObject.GetComponent<TriangleExplosion>().SplitMesh(true));
//Destroy(other.gameObject);
Debug.Log("exploding - exploding - exploding - exploding");
}*/

}



{
DeathPart deathPart = other.transform.GetComponent<DeathPart>();
if (deathPart)
deathPart.HittedDeathPart();
}





rb.velocity = Vector3.zero;
rb.AddForce(Vector3.up, ForceMode.Impulse);

}

public void ResetBall() {
transform.position = startPos;
}
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GameManager : MonoBehaviour {

public static GameManager singleton;
public int best;
public int score;


private void Awake()
{
if (singleton == null)
singleton = this;
else if (singleton != this)
Destroy(gameObject);

// Load the saved highscore
best = PlayerPrefs.GetInt("Highscore");
}

public void NextLevel()
{
FindObjectOfType<BallController>().ResetBall();

}

public void RestartLevel()
{
Debug.Log("Restarting Level");
// Show Adds Advertisement.Show();
singleton.score = 0;
FindObjectOfType<BallController>().ResetBall();
//Reload the Stage
}

public void AddScore(int scoreToAdd)
{
score += scoreToAdd;

if (score > best)
{
best = score;
PlayerPrefs.SetInt("Highscore", score);
}
}


}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DeathPart : MonoBehaviour {

private void OnEnable()
{
GetComponent<Renderer>().material.color = Color.black;


}

public void HittedDeathPart( )
{
GameManager.singleton.RestartLevel();
}
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CharacterCreation : MonoBehaviour
{
private List<GameObject> models;
//Default Index of the model
private int selectionIndex = 0;

private void Start()
{
models = new List<GameObject>();
foreach(Transform t in transform)
{
models.Add(t.gameObject);
t.gameObject.SetActive(false);
}
models[selectionIndex].SetActive(true);
}

private void Update()
{
if (Input.GetKeyDown(KeyCode.A))
Select(4);
}

public void Select (int index)
{
if (index == selectionIndex)
return;

if (index < 0 || index >= models.Count)
return;

models[selectionIndex].SetActive(false);
selectionIndex = index;
models[selectionIndex].SetActive(true);
}

}

 

"My problem is I want to restart my objects when they collide with another object but it only restarts one object."
I really don't understand your problem.
Try to explain your game idea and maybe we can help you.

If it's only about a simple collision and reset all the objects.. then you have 2 options (maybe more)
1. Easiest, i don't recommend it (works for small applications) -> restart your level when your object collide. If your game starts in 20 seconds this is not an option
2. Make a method that reinitialize all the objects. Before that, maybe you need to store all the positions/rotations etc.. of all your objects and then just reactivate and move/rotate your objects in the positions saved before.

 

Please post code using CODE tags, as very few people will even attempt to read pages of unformatted code.
