Profiler.BeginThreadProfiling

Parameters

Description

在调用此方法的线程上启用性能分析。

使线程在性能分析器时间轴视图中与其注册名称一同显示，并显示线程上每个样本的持续时间。 跨帧边界的样本会被切片并且可能为多个帧贡献时间。

Note: Calling this method on an internal Unity thread (such as main thread, render thread or job system threads) has no effect.

using UnityEngine;
using UnityEngine.Profiling;
using System.Threading;

public class ExampleClass : MonoBehaviour
{
    CustomSampler sampler;
    void Start()
    {
        sampler = CustomSampler.Create("MyCustomSampler");
        var thread = new Thread(MyThreadFunc) { IsBackground = true };
        thread.Start();
    }

    void MyThreadFunc()
    {
        Profiler.BeginThreadProfiling("My threads", "My thread 1");
        // Now samples will show up in the profiler timeline view
        for (int i = 0; i < 10; i++)
        {
            sampler.Begin();
            // ...
            sampler.End();
        }

        // Unregister the thread before exit
        Profiler.EndThreadProfiling();
    }
}

注意： 应始终在线程销毁之前调用 Profiler.EndThreadProfiling 来释放内部资源。
