Uobject begin play() equivalent

[anonymous_user_7069a375]

The are right. UObject doesn’t know is World exist. When you create your UObject dynamically with NewObject function, you should pass an Outer(basically “Owner”) - some actor in the world.

To make it work out-of-box:

1. Create your own BeginPlay() function

2. Override PostInitProperties() function(called after the C++ constructor) and call your BeginPlay() in it. But you should be carefull, this function is called in editor too, so you should first check, if World exist.

   void UMyObject::PostInitProperties()
   {
   Super::PostInitProperties();

    //Called in game, when World exist . BeginPlay will not be called in editor
    if(GetWorld())
    {
       BeginPlay();
    }
   

   }

3. Override GetWorld() function in your UObject

   UWorld* UMyObject::GetWorld() const
   {
   // Return pointer to World from object owner, if we don’t work in editor
   if (GIsEditor && !GIsPlayInEditorWorld)
   {
   return nullptr;
   }
   else if (GetOuter())
   {
   return GetOuter()->GetWorld();
   }
   return nullptr;
   }

Thats all, now you have BeginPlay() for your UObject.
Have a nice day)
