I created custom component class which is inherited from StaticMeshComponent.
Here’s my constructor and tick code.
UMyComponent::UMyComponent()
{
PrimaryComponentTick.bCanEverTick = true;
PrimaryComponentTick.TickGroup = TG_PrePhysics;
bAutoActivate = true;
bTickInEditor = true;
}
void UMyComponent::TickComponent(float DeltaTime, enum ELevelTick TickType, FActorComponentTickFunction *ThisTickFunction)
{
Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
GetWorld()->GetFirstPlayerController()->PlayerCameraManager->GetViewTarget();
}
Here’s my problem.
Everytime i reference ViewTarget in TickComponent function, when compile the code, Unreal editor crashes.
Error Log is here.
Access violation - code c0000005 (first/second chance not available)

TickComponent function works fine when the code that reference ViewTarget was removed.
What’s the matter with my code.
p.s. sorry about my bad English…
