💡 Hint

Common Mistakes

Using 'Record', 'Begin', or 'Start' causes a method not found error.

'Enable' is not the correct property name.

The correct property to enable the profiler in Unity is Profiler.enabled = true.

💡 Hint

Common Mistakes

Using 'ProfilerMarker' as variable name shadows the class.

Using 'MyMarker' (string literal) as variable name is invalid.

The variable name should be a valid identifier following conventions like myMarker. Using the class name shadows it; string literals are invalid.

💡 Hint

Common Mistakes

Using 'Pause', 'End', or 'Finish' are not valid Profiler methods.

'Stop' does not exist.

The correct property to disable the profiler in Unity is Profiler.enabled = false.

4fill in blank

hard

Fill both blanks to correctly begin and end a profiling sample with a custom marker.

Unity

var marker = new UnityEngine.Profiling.ProfilerMarker("Sample");
marker.[1]();
// code to profile
marker.[2]();

Drag options to blanks, or click blank then click option'

AAuto

CEnd

DStart

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'Auto' requires a 'using' statement and no manual End.

Using 'Start' is not a valid method on ProfilerMarker.

Use Begin() to start and End() to end the profiling sample with a custom marker.

5fill in blank

hard

Fill all three blanks to create a custom profiler marker and measure a code block.

Unity

UnityEngine.Profiling.ProfilerMarker [1] = new UnityEngine.Profiling.ProfilerMarker("[2]");
[1].[3]();
// code to profile
[1].End();

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'Start()' instead of 'Begin()' causes errors.

Using invalid variable names or string literals as variable names.

First, create a variable customMarker with the name CustomBlock. Then call Begin() to start profiling.
