Application.backgroundLoadingPriority

Descripción

Prioridad del hilo de descarga en segundo plano.

Permite controlar cuánto tiempo se tarda en cargar datos de forma asíncrona frente al impacto de rendimiento en el juego mientras se carga en segundo plano.

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.

El hilo de carga del background utiliza backgroundLoadingPriority directamente.

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    void Example1()
    {
        // Load as much data as possible, as a result frame rate will drop.
        // Good for fast loading when showing progress bars.

        Application.backgroundLoadingPriority = ThreadPriority.High;
    }

    void Example2()
    {
        // Load data very slowly and try not to affect performance of the game.
        // Good for loading in the background while the game is playing.

        Application.backgroundLoadingPriority = ThreadPriority.Low;
    }
}
