How to call this function only once?

Question

I have a Random.ColorHSV that randomizes, well, a color. The problem is , I have about 10 objects with this script running the Random.ColorHSV, so it randomizes 10 times. How can I have it randomized only once?

Thanks in advance!

If you mean you want to random the color once and share it within the 10 objects, you can have a super-class do the randoming and store it there for the 10 objects to just access it as a property.

EDIT: You can do it a couple of ways, an easy one is to make a new script and attach it to a gameobject in your scene that could be acting as a game manager (having functions to manage the game's state or so) and make it randomize the color at the start of the game.

 public Class GameManager : Monobehaviour {
     public static Color randomizedColor;

     void Start(){  //you can also use Awake here if the objects take their color in their Start method
         randomizedColor = Random.ColorHSV(0f, 1f, 1f, 1f, 0.5f, 1f);
    }
 }

And then in your objects you can call:

 currentObsColor = GameManager.randomizedColor;

Excuse my ignorance, but how exactly do I go about this? I tried my best but the result is the same.

Here's my class:

 public class RandomizeObstacleColor
     {
         public Color randomizedColor = 
         Random.ColorHSV(0f, 1f, 1f, 1f, 0.5f, 1f);
     }

And here is my reference:

 currentObsColor = new RandomizeColor.RandomizeObstacleColor().randomizedColor;

Thanks!
