Random.value

Description

Возвращает случайное число между 0.0 [вкл] и 1.0 [вкл] (Read Only).

Both 0.0 and 1.0 may be returned by this property. This behaviour is different to that of many other random number generators which return a value less than but never exactly equal to 1.0.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        Color randomColor = RandomColor();
    }

    // Generate a random color value.
    Color RandomColor()
    {
        // A different random value is used for each color component (if
        // the same is used for R, G and B, a shade of grey is produced).
        return new Color(Random.value, Random.value, Random.value);
    }
}
