ResourcesAPI

描述

Derive from this base class to provide alternative implementations to the C# behavior of specific Resources methods.

The example provided logs the time taken to handle slower Resources APIs to the player or editor log.

using Object = UnityEngine.Object;
using Debug = UnityEngine.Debug;

public class ResourcesPerformanceLogger : ResourcesAPI
{
    [RuntimeInitializeOnLoadMethod]
    static void OnRuntimeMethodLoad()

    {

        timer.Start();
        Object[] results = base.FindObjectsOfTypeAll(systemTypeInstance);
        timer.Stop();
        Debug.Log($"FindObjectsOfTypeAll({systemTypeInstance}) Time: {timer.Elapsed}");
        return results;
