Menu Level

说明

主菜单其实是个空关卡, 相对应的, 会需要关卡相关的类

-
STUMenuGameModeBase
STUMenuPlayerController
STUMenuHUD
STUMenuWidget

创建C++类和对应蓝图

创建文件夹

• Content/Menu
  
• Content/Menu/UI
  

名称	基类	路径	属性
STUMenuGameModeBase	GameModeBase	Menu	Public
STUMenuPlayerController	PlayerController	Menu	Public
STUMenuHUD	HUD	Menu/UI	Public
STUMenuWidget	UserWidget	Menu/UI	Public

C++类	蓝图	路径
STUMenuGameModeBase	BP_STUMenuGameModeBase	Content/Menu
STUMenuPlayerController	BP_STUMenuPlayerController	Content/Menu
STUMenuHUD	BP_STUMenuHUD	Content/Menu/UI
STUMenuWidget	WBP_Menu	Content/Menu/UI

可以不创建BP_STUMenuPlayerController

创建主菜单

1. 创建关卡, 命名为 MenuLevel

Content/Menu
   

2. 往关卡中添加指数级高度雾
   
   Exponential Height Fog
   

   设置颜色
   

   -
   Fog Inscattering Color > Hex Linear	0027CFFF

   

   
   

3. 设置编辑器和游戏默认载入关卡
   
   Edit > Project Settings.. > Project > Maps & Modes > Default Maps
   

   -
   Editor Startup Map	MenuLevel
   Game Default Map	MenuLevel

4. 设置关卡使用类型
   
   World Settings
   

   -
   GameMode Override	BP_STUMenuGameModeBase
   HUD Class	BP_STUMenuHUD
   Player Controller Class	BP_STUMenuPlayerController

   

   
   

设计WBP_Menu

1. 从WBP_PauseWidget拷贝整个 Canvas Panel
   

2. 在WBP_Menu中粘贴 Canvas Panel
   

3. 修改文本
   

   

   
   

4. 修改按钮文本
   

   

   
   

5. 修改按钮变量名
   

   

   
   

修改头文件搜索路径

ShootThemUp: ShootThemUp.Build.cs

Copy 1PublicIncludePaths.AddRange(new string[]
 2{
 3    "ShootThemUp/Public/Player",
 4    "ShootThemUp/Public/Components",
 5    "ShootThemUp/Public/Dev",
 6    "ShootThemUp/Public/Weapon",
 7    "ShootThemUp/Public/UI",
 8    "ShootThemUp/Public/Animations",
 9    "ShootThemUp/Public/Pickups",
10    "ShootThemUp/Public/Weapon/Components",
11    "ShootThemUp/Public/AI",
12    "ShootThemUp/Public/AI/Tasks",
13    "ShootThemUp/Public/AI/Services",
14    "ShootThemUp/Public/AI/EQS",
15    "ShootThemUp/Public/AI/Decorators",
16    "ShootThemUp/Public/Menu",
17    "ShootThemUp/Public/Menu/UI"
18});

实现STUMenuGameModeBase

添加构造函数, 设置PlayerController和HUD默认类型

public

ShootThemUp: Menu/STUMenuGameModeBase.h

Copy1ASTUMenuGameModeBase();

ShootThemUp: Menu/STUMenuGameModeBase.cpp

Copy1#include "Menu/STUMenuPlayerController.h"
2#include "Menu/UI/STUmenuHUD.h"
3
4ASTUMenuGameModeBase::ASTUMenuGameModeBase()
5{
6    PlayerControllerClass = ASTUMenuPlayerController::StaticClass();
7    HUDClass = ASTUMenuHUD::StaticClass();
8}

实现STUMenuPlayerController

覆写BeginPlay函数, 输入模式为UIOnly, 全程显示鼠标光标

protected

ShootThemUp: Menu/STUMenuPlayerController.h

Copy1virtual void BeginPlay() override;

ShootThemUp: Menu/STUMenuPlayerController.cpp

Copy1void ASTUMenuPlayerController::BeginPlay()
2{
3    Super::BeginPlay();
4
5    bShowMouseCursor = true;
6    SetInputMode(FInputModeUIOnly());
7}

实现STUMenuHUD

覆写BeginPlay函数, 创建窗口部件, 并添加到视口

1. 添加属性: 保存窗口部件类型
   
   protected

ShootThemUp: Menu/UI/STUMenuHUD.h
   

   Copy1class UUserWidget;
   2
   3UPROPERTY(EditDefaultsOnly, BlueprintReadWrite)
   4TSubclassOf<UUserWidget> MenuWidgetClass;

2. 覆写BeginPlay函数
   
   protected

ShootThemUp: Menu/UI/STUMenuHUD.h
   

   Copy1virtual void BeginPlay() override;

   ShootThemUp: Menu/UI/STUMenuHUD.cpp
   

   Copy 1#include "Blueprint/UserWidget.h"
    2
    3void ASTUMenuHUD::BeginPlay()
    4{
    5    Super::BeginPlay();
    6
    7    if (MenuWidgetClass)
    8    {
    9        const auto MenuWidget = CreateWidget<UUserWidget>(GetWorld(), MenuWidgetClass);
   10        if (MenuWidget)
   11        {
   12            MenuWidget->AddToViewport();
   13        }
   14    }
   15}

实现STUMenuWidget

覆写NativeOnInitialized, 注册按钮点击事件

1. 添加属性: 按钮
   
   protected

ShootThemUp: Menu/UI/STUMenuWidget.h
   

   Copy1class UButton;
   2
   3UPROPERTY(meta = (BindWidget))
   4UButton *StartGameButton;

2. 实现回调函数
   

   不要遗漏UFUNCTION宏
   
   private

ShootThemUp: Menu/UI/STUMenuWidget.h
   

   Copy1UFUNCTION()
   2void OnStartGame();

   ShootThemUp: Menu/UI/STUMenuWidget.cpp
   

   Copy1#include "Kismet/GameplayStatics.h"
   2
   3void USTUMenuWidget::OnStartGame()
   4{
   5    const FName LevelName = "DefaultMap"; /* StartupLevelName */
   6
   7    UGameplayStatics::OpenLevel(GetWorld(), LevelName);
   8}

3. 覆写NativeOnInitialized, 注册回调函数
   
   protected

ShootThemUp: Menu/UI/STUMenuWidget.h
   

   Copy1virtual void NativeOnInitialized() override;

   ShootThemUp: Menu/UI/STUMenuWidget.cpp
   

   Copy 1#include "Components/Button.h"
    2
    3void USTUMenuWidget::NativeOnInitialized()
    4{
    5    Super::NativeOnInitialized();
    6
    7    if (StartGameButton)
    8    {
    9        StartGameButton->OnClicked.AddDynamic(this, &USTUMenuWidget::OnStartGame);
   10    }
   11}
