Random.Range

Parameters

Description

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

Note that max is inclusive, so using Random.Range( 0.0f, 1.0f ) could return 1.0 as a value.

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);
    }
}

Parameters

Description

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

Note that max is exclusive, so using Random.Range( 0, 10 ) will return values between 0 and 9. If max equals min, min will be returned.

using UnityEngine;

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

    void Start() 
    {
        Application.LoadLevel( Random.Range( 0, Application.levelCount ) );
    }
}
