Application.LoadLevelAsync 异步加载关卡

static function LoadLevelAsync (levelName : string) : AsyncOperation

Description描述

Loads the level asynchronously in the background.

在后台异步加载关卡,也就是说,在后台非同步加载新的场景。

Unity will completely load all assets and all objects in the scene in a background loading thread. This allows you to load new levels while still playing the current one, show a progress bar or create a completely streaming world where you constantly load and unload different parts of the world based on the player position, without any hiccups in game play.

Unity将在后台线程完整加载场景所有资源和物体。这允许你加载一个新的关卡,同时当前的关卡仍在播运行,显示进度条或者创建一个完整的流世界,在那里你不断的加载和卸载基于程序位置不同的部分,在游戏中不会有任何的中断。

isDone variable from the resulting AsyncOperation can be used to query if the level load has completed. The result of a LoadLevelAsync can also be used to yield in a coroutine.

isDone变量来自AsyncOperation异步操作的结果,可以用于如果关卡加载完成的查询。

When building a player Unity automatically optimizes assets in such a way that LoadLevelAsync will load them from disk linearly to avoid seek times. Note that background loading performance in the Unity Editor is much lower than in the web player or standalone build. In the Editor you might also get more loading hiccups than in the player.

当编译一个游戏Unity自动优化资源,LoadLevelAsync将从硬盘以线性加载它们避免从磁盘寻道时间。

注意,背景加载优先级在Unity编辑器远远低于网络播放器或独立版编译。在编辑器你或许也得到比播放器更多的加载中断。

public class example : MonoBehaviour {
	IEnumerator Start() {
		AsyncOperation async = Application.LoadLevelAsync("MyBigLevel");
		yield return async;
		Debug.Log("Loading complete");
	}
}
function Start () {
	// Load the level named "MyBigLevel".
	//加载名为MyBigLevel的场景
	var async : AsyncOperation = Application.LoadLevelAsync ("MyBigLevel");
	yield async;
	Debug.Log("Loading complete");
