Description

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 System;
using System.Diagnostics;
using UnityEngine;
using Object = UnityEngine.Object;
using Debug = UnityEngine.Debug;

public class ResourcesPerformanceLogger : ResourcesAPI { [RuntimeInitializeOnLoadMethod] static void OnRuntimeMethodLoad() { ResourcesAPI.overrideAPI = new ResourcesPerformanceLogger(); }

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

protected override Shader FindShaderByName(string name) { Stopwatch timer = new Stopwatch(); timer.Start(); Shader result = base.FindShaderByName(name); timer.Stop(); Debug.Log($"FindShaderByName({name}) Time: {timer.Elapsed}"); return result; }

protected override Object[] LoadAll(string path, Type systemTypeInstance) { Stopwatch timer = new Stopwatch(); timer.Start(); Object[] results = base.LoadAll(path, systemTypeInstance); timer.Stop(); Debug.Log($"LoadAll({path}, {systemTypeInstance}) Time: {timer.Elapsed}"); return results; } }
