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

説明

Return a random float number between min [inclusive] and max [inclusive] (Read Only).

Note max is inclusive. Random.Range(0.0f, 1.0f) can return 1.0 as the value. The Random.Range distribution is uniform. Range is a Random Number Generator.

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 int Range (int min, int max);

説明

Return a random integer number between min [inclusive] and max [exclusive] (Read Only).

Note max is exclusive. Random.Range(0, 10) can return a value between 0 and 9. Return min if max equals min. The Random.Range distribution is uniform. Range is a Random Number Generator.

using UnityEngine.SceneManagement;

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

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