public static string logFile ;


Specifies the file to use when writing profiling data.

In addition to specifying a valid file path, you must set both Profiler.enabled and Profiler.enableBinaryLog to true in order to save profiling information. Specifying a new valid file path while Profiler.enableBinaryLog is true will save profiling information to that file instead. If a null or an empty path is passed Profiler.enableBinaryLog will automatically be set to false.

public class ExampleClass : MonoBehaviour { void Start() { Profiler.logFile = "mylog"; //Also supports passing "myLog.raw" Profiler.enableBinaryLog = true; Profiler.enabled = true; } }
