Random.rotation

説明

ランダムな Quaternion 型の値を返します（読み取り専用）

Randomize the x, y, z, and w of a Quaternion each to [-1.0..1.0] (inclusive) via Range and normalize the result. See also rotationUniform for a slower but higher quality algorithm.

using UnityEngine;

// Click the "Rotate!" button and a rotation will be applied

public class ExampleClass : MonoBehaviour
{
    void OnGUI()
    {
        if (GUI.Button(new Rect(10, 10, 100, 50), "Rotate!"))
        {
            transform.rotation = Random.rotation;
        }
    }
}
