How to calculate the distance between array gameObject? - arrays

Question

How to calculate the distance between the generated cubes. The assigned script on the dice only specifies a different speed. How is the distance between the individual instantiate cubes calculated?
Sorry for the bad English, I'm using google trnslator. I'm attaching the code, and I'm a beginner in the unit
public class vehicless : MonoBehaviour
{
[SerializeField] private GameObject[] vehicle;
[SerializeField] private Transform spawnPos;
[SerializeField] private float minTime;
[SerializeField] private float maxTime;
int randomInt;
// Use this for initialization
void Start ()
{
StartCoroutine(SpawnVehicle());
}
// Update is called once per frame
void Update ()
{
}
private IEnumerator SpawnVehicle()
{
int i=1;
while(true)
{
randomInt = Random.Range(0,vehicle.Length);
yield return new WaitForSeconds(Random.Range(minTime,maxTime));
GameObject myPrefabInstance = Instantiate(vehicle[randomInt],spawnPos.position,Quaternion.identity);
var red = myPrefabInstance.gameObject.name; //NAME OBJECT
var namecube = red + i ;
Debug.Log("Name object:"+namecube ) ;
i++;
}
}
}
// float dist = Vector3.Distance(----------);
Thanks for help

If you need to quickly find the distance between 2 objects i suggest you to stock the distance in a dictionary with Tuple Key = (GameObject, GameObject) and Value = float:
Dictionary<(GameObject, GameObject), float>()
public Dictionary<(GameObject, GameObject), float>() calculate(GameObject[] objs)
{
var distanceArray = new Dictionary<(GameObject, GameObject), float>();
for (int i = 0; i < objs.Length; i++)
{
for (int j = i; j < objs.Length; j++)
{
if (i == j)
{
//distance between same obj is 0f
continue;
}
else
{
distanceArray.Add((objs[i], objs[j]), Vector3.Distance(objs[i].transform.position, objs[j].transform.position));
}
}
}
return distanceArray;
}
After you could quickly find the distance between 2 object like this:
if (distanceArray.ContainsKey((obj1, obj2)))
{
distance = distanceArray[(obj1, obj2)];
}
else if (distanceArray.ContainsKey((obj2, obj1)))
{
distance = distanceArray[(obj2, obj1)];
}
else if (obj1 == obj2)
{
distance = 0f;
}
else
{
//Error
}
Your question is not very easy to understand, i just add the way to calculate the distance after each new spawned vehicle:
GameObject myPrefabInstance = Instantiate(vehicle[randomInt],spawnPos.position,Quaternion.identity);
for (int i = 0; i < vehicle.Length; i++)
{
var distance = Vector3.distance(myPrefabInstance.transform.position, vehicle[i].transform.position);
Debug.Log($"Distance: {distance}");
}

I imagine that the cubes have different speeds, objects can be a lot, for example 10.15 cubes and a cube that will have a higher speed to slow down in front of a cube that has a slower speed.
