class in Unity.IO.LowLevel.Unsafe

切换到手册

描述

A summary of the metrics collected for AsyncReadManager read operations.

Get a summary of the current metrics by calling AsyncReadManagerMetrics.GetCurrentSummaryMetrics. This function summarizes all metrics recorded since you started metrics collection or last cleared your metrics data. Get a summary of an existing set of AsyncReadManagerRequestMetric records by calling AsyncReadManagerMetrics.GetSummaryOfMetrics. You can get these records by calling AsyncReadManagerMetrics.GetMetrics. In both cases, you can filter the data with AsyncReadManagerMetricsFilters in order to focus the summary on the particular categories of data you want to analyze. See Also: AsyncReadManagerMetrics.

public class GetMetricsSummary : MonoBehaviour { #if ENABLE_PROFILER && UNITY_2020_2_OR_NEWER AsyncReadManagerMetricsFilters m_Filter; AsyncReadManagerSummaryMetrics m_Summary; public void Start() { // Create a filter for texture file reads that have been completed m_Filter = new AsyncReadManagerMetricsFilters(); m_Filter.SetStateFilter(ProcessingState.Completed); }

public void Update() { m_Summary = AsyncReadManagerMetrics.GetCurrentSummaryMetrics(m_Filter, AsyncReadManagerMetrics.Flags.ClearOnRead); Debug.Log($"Last frame bandwidth: {m_Summary.AverageBandwidthMBPerSecond} MB/s."); }
