Toon Tank Final challenge menu implementation

[Philx]

I try to implement menu and I’m not sure of the step!

I created a C++ UserWidget and a child widget blueprint and created a menu with a start game button to begin. In the TankGameModeBase I created a blueprint implementable event GameMenu() so I can call it in BeginPlay. So after these steps everythings work but I’m not sure what to do after do I create a reference to TankGameModeBase in my UserWidget to call the HandleGameStart function?
Here what I had done in my UserWidget:

#include "MainMenuWidget.h"
#include "Components/Button.h"
#include "ToonTanks/GameModes/TankGameModeBase.h"

bool UMainMenuWidget::Initialize()
{
	Super::Initialize();
	UWorld* TheWorld = GetWorld();
	if (TheWorld != nullptr)
	{
		//How do cast to Game mode?
		GameMode = Cast<ATankGameModeBase>(UGameplayStatics::GetGameMode(TheWorld));
		StartGame->OnClicked.AddDynamic(this, &UMainMenuWidget::StartButtonClicked);

		return true;
	}
	
}

void UMainMenuWidget::StartButtonClicked()
{
	UE_LOG(LogTemp, Warning, TEXT("button working"));	
}

Thank you for all your assistance and great thanks to GameDev.Tv for this course! The best I followed on Udemy!

Is that not working?

P.S. your Initialize function doesn’t return a value if TheWorld == nullptr

[Philx]

finally it was missing #include “Kismet/GameplayStatics.h”
still some beginner error
Is their another way to call the HandleGameStart() of TankGameModeBase?
Something like a blueprint event call or something like that. I will continue some tests and research! Thanks for your reply!

I finally got some results but I can’t remove my menu after opening a level.

I created a “plain” level for the main menu with a custom Menu Game Mode. I override it in the level detail. When I click on Start button it open level 1 with the tank but the menu is still visible.

I override the game level with the BP_GameModeBase but no change.

I add RemoveParent() function in c++ OnClicked button function, it work when I don’t add the open level function to the button in blueprint. I try to add it in blueprint to but still no difference.

Thanks for your help!

And if you remove it from parent before calling open level?

[Philx]

No same thing it do not hide the menu. Each time I click on start game it reload the level and I think the menu is reloaded with it but their is no call of it in the game mode of the open level! I will continue to test more things today!

Finally I erase my first User Widget and child and re code a new one with same pattern that work in blueprint. Finally got it! I made a Menu Game Mode and a blank Level with this Game Mode like I have done before.
My Menu header file:

#pragma once

#include "CoreMinimal.h"
#include "Blueprint/UserWidget.h"
#include "MenuMaster.generated.h"

/**
 * 
 */
UCLASS()
class TOONTANKS_API UMenuMaster : public UUserWidget
{
	GENERATED_BODY()
protected:

	virtual bool Initialize();

	UPROPERTY(EditAnywhere)
	FName LevelToLoad;
	UPROPERTY(meta = (BindWidget))
	class UButton* StartGame;
	UPROPERTY(meta = (BindWidget))
	class UButton* ExitGame;
	UFUNCTION()
	void StartButtonClicked();
	UFUNCTION()
	void ExitButtonClicked();
};

And my Menu cpp:

#include "MenuMaster.h"
#include "Components/Button.h"
#include "Kismet/GameplayStatics.h"


bool UMenuMaster::Initialize()
{
	
	Super::Initialize();
	if (StartGame != nullptr && ExitGame != nullptr)
	{
		StartGame->OnClicked.AddDynamic(this, &UMenuMaster::StartButtonClicked);
		ExitGame->OnClicked.AddDynamic(this, &UMenuMaster::ExitButtonClicked);		
	}
	return true;
}

void UMenuMaster::StartButtonClicked()
{
		UGameplayStatics::OpenLevel(this, LevelToLoad, true);
}

void UMenuMaster::ExitButtonClicked()
{
	GetWorld()->GetFirstPlayerController()->ConsoleCommand("quit");
}

It was a really big challenge

And thanks DanM for your dedication to the community! Your support encourage me to continue and I made it!
