Problem with random Range, returns always same number

Questions & Answers

well, as it says the title, ive made a small function to return a random vector3, but always returns the same values, not doing random.
It always returns 0.1,0.1,0.1

void RandomVector(Vector3 a)
{
float uno = Random.Range(0.05f, 0.15f);
float dos = Random.Range(0.05f, 0.15f);
float tres = Random.Range(0.05f, 0.15f);
    a = new Vector3(uno, dos, tres);
    Debug.Log(a);
}

The vector is correct the debug is just not showing the full float number change your debug for:

Debug.Log(a.ToString("F4"));

In order not to repeat a number twice you might try storing the value of the first number.
For example .

int [] array = new int[]{0,1,2,3,4,5,6};
 List<int>list = null;
 void Start(){
     list.AddRange(array);
 }
 int GetUniqueRandom(bool reloadEmptyList){
      if(list.Count == 0 ){
          if(reloadEmptyList){
              list.AddRange(array); 
          }
          else{
              return -1; // here is up to you 
         }
     }
    int rand = Random.Range(0, list.Count);
    int value = list[rand];
    list.RemoveAt(rand);
    return value;
 }

I hope it helps you.

It was a problem related to seeds and stuf, couldnt fix it, it always returned the same amount no matter what, but i found an easier way, ill put it here in case someone needs.

with only one sentence i could do all that shit.

vector3random = Random.insideUnitSphere * DistanciaMax;

Random.insideUniteSphere returns a random value inside a sphere of radius 1.
