public static function Range(min: float, max: float): float;
public static float Range(float min, float max);

Parameters

Description

min (この値を含む) と max (この値を含む) の範囲のランダムな float 型の数を返します (読み取り専用)。

max は範囲に含まれるため、Random.Range( 0.0f, 1.0f ) は返り値として 1.0 を含みます。

no example available in JavaScript
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public GameObject prefab; // Instantiate the prefab somewhere between -10.0 and 10.0 on the x-z plane void Start() { Vector3 position = new Vector3(Random.Range(-10.0f, 10.0f), 0, Random.Range(-10.0f, 10.0f)); Instantiate(prefab, position, Quaternion.identity); } }

public static function Range(min: int, max: int): int;
public static int Range(int min, int max);

Parameters

Description

min (この値を含む) と max (この値を含まない) の範囲のランダムな整数を返します (読み取り専用)。

max は範囲から除外されるため、Random.Range( 0, 10 ) は 0 から 9 の間の値を返します。 maxmin が等しければ、min が返されます。

using UnityEngine;

public class ExampleClass : MonoBehaviour { // Loads a random level from the level list

void Start() { SceneManager.LoadScene( Random.Range( 0, SceneManager.sceneCount ) ); } }
