```
using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public GameObject prefab;
	void Start() {
		Vector3 position = new Vector3(Random.Range(-10, 10), 0, Random.Range(-10, 10));
		Instantiate(prefab, position, Quaternion.identity);
	}
}
```

```
// Instantiates prefab somewhere between -10 and 10 on the x-z plane
//在x-z平面实例化预设，-10～10之间

var prefab : GameObject;
function Start () {
	var position = Vector3(Random.Range(-10, 10), 0, Random.Range(-10, 10));
	Instantiate(prefab, position, Quaternion.identity);
}
```

• static function *Range* (*min* : int, *max* : int) :
int

*Description* 描述

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

返回一个随机整数，在 min（包含）和 max（包含）之间。（只读）

If max equals min, min will be returned. The returned value will never be max
unless min equals max.

如果 max 等于 min，将返回 min。返回值永远不会是 max，除非 min 等于 max。
