本文详细介绍了如何在Unity中使用DontDestroyOnLoad函数，使对象在加载新场景时不被销毁。该函数可以确保指定的游戏对象或组件在场景切换时保持不变，这对于跨场景保留状态非常有用。

static function DontDestroyOnLoad (target : Object) : void

Description

Makes the object target not be destroyed automatically when loading a new scene.

When loading a new level all objects in the scene are destroyed, then the objects in the new level are loaded. In order to preserve an object during level loading call DontDestroyOnLoad on it. If the object is a component or game object then its entire transform hierarchy will not be destroyed either.

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    void Awake() {
        DontDestroyOnLoad(transform.gameObject);
    }
}

Note though that you will need to call Object.Destroy() if you decide to load a new scene and do not need those objects around anymore, otherwise they will persist until the application dies.
