説明

バックグラウンドのスレッドの優先順位を設定します。

バックグラウンドで読み込んでいる間、「非同期的にデータを読み込むのにかかる時間」か「ゲームへのパフォーマンス的影響」のどちらを犠牲にするかを制御します。

Asynchronous load functions that load objects (Resources.LoadAsync, AssetBundle.LoadAssetAsync, AssetBundle.LoadAllAssetAsync), scenes (SceneManager.LoadSceneAsync) do data read and deserealization on a separate background loading thread and object integration on a main thread. Integration depends on an object type and for textures, meshes means uploading data to the GPU, audio clips prepare data for playing.

To avoid hiccups we limit integration time on a main thread depending on backgroundLoadingPriority value:
- ThreadPriority.Low - 2ms;
- ThreadPriority.BelowNormal - 4ms;
- ThreadPriority.Normal - 10ms;
- ThreadPriority.High - 50ms.
This is a maximum time all asynchronous operations can spend within a single frame on a main thread.

バックグラウンド ローディング スレッドは、直接、backgroundLoadingPriority を使用します。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Example() { Application.backgroundLoadingPriority = ThreadPriority.High; Application.backgroundLoadingPriority = ThreadPriority.Low; } }
