Set Maximum Delta Time between frames; helpful for debugging by t.OverrideFPS or UGameEngine::MaxDeltaTime

  • MaxDeltaTime is unusable in network games (look at UpdateTimeAndHandleMaxTickRate)

FixupDeltaSeconds(DeltaSecondsRealDeltaSeconds);

APawn::MoveIgnoreActorAdd()

* Handles game-specific networking management (cheat detection, bandwidth management, etc.).

Changing Component Ownership:#

  1. void RegisterTImelineWithActor(UTimelineComponent* Timeline, AActor* Actor)

  2. {

  3. // Might want to save this if it’s not the TransientPackage / World.

  4. UObject* OriginalOwner = Timeline->GetOuter();

  5. FString OriginalName = Timeline->GetName();

  6. // We can leave the name alone.

  7. Timeline->Rename( *OriginalName, Actor );

  8. Actor->AddInstancedComponent(Timeline);

  9. Timeline->RegisterAllTickFunctions(true);

  10. // At this point, you can perform any other setup / re-initialization needed on the

  11. // timeline. Also, GetOwner in the Timeline should now return the passed in

  12. // Actor.

  13. }

  14. void UnregisterTimelineComponent(UTimelineComponent* Timeline)

  15. {

  16. AActor* Actor = Timeline->GetOwner();

  17. // This will unregister tick functions.

  18. Timeline->Rename(*OriginalName, OriginalOuter);

  19. }
