For this use case you should make a custom GameInstance, and create your manager objects from there.
class MyGameInstance : public UGameInstance
{
private:
UPROPERTY()
UGameManager * GameManager ;
// UPROPERTY() is necessary to prevent from being garbage collected
}
You’ll also need to change the default GameInstance from Project Setting:
Edit->Project Settings->Maps & Modes->GameInstanceClass -> "MyGameInstance"
GameInstance don’t have Tick function, but you can achieve the same thing using a looping timer.
