Variables, Timers, and Events tutorial not working in 4.7.6

Using the sample code from

https://docs.unrealengine.com/latest/INT/Programming/Tutorials/VariablesTimersEvents/2/index.html

I was not able to reproduce the results shown when executing the code. The instance of the CountdownTimer has no root component according to the editor.

Hello, rogueyoshi

Sorry to hear about your problem.
Please make sure you have the following lines

UTextRenderComponent* CountdownText;

in Actor’s header and

CountdownText = CreateDefaultSubobject<UTextRenderComponent>(TEXT("CountdownNumber"));
CountdownText->AttachTo(RootComponent);
RootComponent = CountdownText;

in Actor’s constructor.

Also please note that after the best way to ensure that code changes have been applied correctly is to save the level, close the Editor and recompile the project.

Hope this helped!

Good luck!
