\*\*Get Widgets of Class

Ideal for UMG Level Transitions\*\*

I needed node for Solus and so I am now sharing it with you!

The was that I could not save a reference to my new widget because it is loaded and then a level change occurs which resets my HUD variables.

So I needed to access the widget after it was created dynamically, not relying on stored references within the HUD class.

I also did not want to have to store a reference to it in my Game Instance class cause then that leads to garbage collection issues.

I had to make the node for my own use and I have tested it as working in Solus!

\*\*Now you can retrieve an array of any type of user-made UMG widget that is currently in your game at any!  
\*\*

```auto

**C++ Code**

Here’s what my C++ for node looks like!

```auto

void UVictoryBPFunctionLibrary::GetAllWidgetsOfClass(UObject* WorldContextObject, TSubclassOf<UUserWidget> WidgetClass, TArray<UUserWidget*>& FoundWidgets)
{
	//Prevent possibility of an ever-growing array if user uses in a loop
	FoundWidgets.Empty();
	// ~~~~~~~~~~~~
	 
	if(!WidgetClass) return;
	if(!WorldContextObject) return;
	 
	UWorld* const World = GEngine->GetWorldFromContextObject(WorldContextObject);
	if(!World) return;
	// ~~~~~~~~~~~
	
	for(TObjectIterator<UUserWidget> Itr; Itr; ++Itr)
	{
		if(Itr->() != World) continue;
		// ~~~~~~~~~~~~~~~~~~~~~
		
		if(Itr->IsA(WidgetClass))
		{
			FoundWidgets.Add(*Itr);
		}
	}
}

```

```auto
