ProfilerUnsafeUtility.BeginSampleWithMetadata

매뉴얼로 전환
public static void BeginSampleWithMetadata (IntPtr markerPtr, int metadataCount, void* metadata);

파라미터

markerPtr Profiler marker handle.
metadataCount Metadata parameters count.
metadata Unsafe pointer to the ProfilerMarkerData array.

설명

Starts profiling a piece of code marked with a custom name that the markerPtr handle and metadata parameters has defined.

Code marked with BeginSampleWithMetadata and EndSample shows up in the Profiler hierarchy. Always use EndSample to close a started section of the instrumented code.
In the Timeline view of the Profiler Window the provided metadata is available in the tooltip message. Use HierarchyFrameDataView.GetItemMetadata to retrieve metadata programmatically.

Note: Both BeginSampleWithMetadata and EndSample are thread safe and can be used in jobified code.
The low level Profiler API is included in a Release Build.

static readonly IntPtr markerHandle = MakeMarkerWithIntMetadata("MyMarker", "Work Idx");

static unsafe void DoWork(int num) { var metadata = stackalloc ProfilerMarkerData[1]; metadata[0].Type = (byte)ProfilerMarkerDataType.Int32; metadata[0].Size = (uint)UnsafeUtility.SizeOf<int>(); metadata[0].Ptr = UnsafeUtility.AddressOf(ref num); ProfilerUnsafeUtility.BeginSampleWithMetadata(markerHandle, 1, metadata); //... ProfilerUnsafeUtility.EndSample(markerHandle); } }

Use Recorder to obtain per-frame timings in the Player for the specific marker name.
