Declaration

public Unity.Profiling.Editor.ProfilerModuleViewController CreateDetailsViewController();

Returns

ProfilerModuleViewController Returns a ProfilerModuleViewController derived object that draws the module’s Details View in the Profiler window. The default value is a view controller that displays a list of the module’s chart counters alongside their current values in the selected frame.

Description

Creates a View Controller object that draws the Profiler module’s Details View in the Profiler window. Unity calls this method automatically when the module is selected in the Profiler window.

To present a bespoke visualization of your performance data when your module is selected, override this method. To do this, define a new ProfilerModuleViewController derived type, where the custom drawing can be implemented, and return a new instance of it in this method.
