Destroying an Actor using Destroy and a Timer

This recipe will reuse the GameMode from the previous recipe, so you should complete it first.

How to do it...

1. Make the following changes to the GameMode declaration:

   UPROPERTY()
   AMyFirstActor* SpawnedActor;
   UFUNCTION()
   void DestroyActorFunction();

2. Add #include "MyFirstActor.h" to the implementation file's includes.
3. Assign the results of SpawnActor to the new SpawnedActor variable:

   SpawnedActor = GetWorld()->SpawnActor<AMyFirstActor> (AMyFirstActor::StaticClass(), SpawnLocation);

4. Add the following to the end of the BeginPlay function:

   FTimerHandle Timer;
   GetWorldTimerManager().SetTimer(Timer, this, &AUE4CookbookGameMode::DestroyActorFunction, 10);

5. Lastly, implement DestroyActorFunction:

   void AUE4CookbookGameMode::DestroyActorFunction() ...
