Random.rotationUniform

説明

ランダムな Quaternion 型の値を返します（読み取り専用）

Employs Hopf fibration to return a random Quaternion within a uniformly distributed selection space. Gives higher quality results compared to the more naive approach employed by rotation, though at a 40% performance cost.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Sets a random orientation for the object.
        transform.rotation = Random.rotationUniform;
    }
}
