Problems with widgets in Code

[VeyDlin]

I use this tutorial https://wiki.unrealengine.com/UMG,_Referencing_UMG_Widgets_in_Code

But every time I have error:

Error Only Local Player Controllers can be assigned to widgets.

I also have this problem with the code.
However, the program compiles without errors.

#pragma once

#include "GameFramework/PlayerController.h"
#include "CustomPlayerController.generated.h"

UCLASS()
class INDIGOPROJECT_API ACustomPlayerController : public APlayerController {
	GENERATED_BODY()

public:
	ACustomPlayerController(const class FObjectInitializer& ObjectInitializer);

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Widgets")
	TSubclassOf<class UUserWidget> MainHUD;
	
protected:
	virtual void BeginPlay() override;
	class UUserWidget* MainHUDWidget;
};

#include "IProject.h"
#include "CustomPlayerController.h"
#include "Runtime/UMG/Public/Blueprint/UserWidget.h"

ACustomPlayerController::ACustomPlayerController(const class FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer) { }

void ACustomPlayerController::BeginPlay() {
	Super::BeginPlay();

	if(MainHUD) {
		MainHUDWidget = CreateWidget<UUserWidget>(this, MainHUD);
		if(MainHUDWidget) {
			MainHUDWidget->AddToViewport();
		}
	}
}

The code error is just intellisense, it doesn’t work well with UE4. Just ignore intellisense errors.

I’m guessing you’re running this with multiple players? The player controller will exist on both the server and the associated client, but you only want to create widgets on each client.
In your BeginPlay method, wrap all the code creating the widget with if(IsLocalPlayerController()) { … }

void ACustomPlayerController::BeginPlay() {
	Super::BeginPlay();

	if(MainHUD && **GetNetMode()!=NM_DedicatedServer**) {
		MainHUDWidget = CreateWidget<UUserWidget>(this, MainHUD);
		if(MainHUDWidget) {
			MainHUDWidget->AddToViewport();
		}
	}
}

That won’t work. If you have a listen server, it will try to create a widget locally for every connected player since you have multiple player controllers on the server.
You need to use IsLocalPlayerController().

At the VS has tips on entering, they no longer work.
I find it difficult to work under such conditions

Thank you!

IsLocalPlayerController() worked.
