Random.value

説明

Returns a random float within [0.0..1.0] (range is inclusive) (Read Only).

Important: Both the lower and upper bounds are inclusive. Any given float value between 0.0 and 1.0, including both 0.0 and 1.0, will appear on average approximately once every ten million random samples.

See Random for more examples of how UnityEngine.Random may be different from other random number generators.

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);
    }
