七、Debug与游戏设置控件

Debug

SlAiHelper.h

#pragma once

#include"CoreMinimal.h"
#include"Engine/World.h"
#include"Engine/GameEngine.h"

namespace SlAiHelper {
    
    

	//Debug
	FORCEINLINE void Debug(FString Message, float Duration = 100.f) {
    
    
		if (GEngine) {
    
    
			GEngine->AddOnScreenDebugMessage(-1, Duration, FColor::Yellow, Message);
		}
	}
}

通过CheckBox实现切换中英文

设置样式

/*
	* GameSet的背景
	*/
	UPROPERTY(EditAnywhere, Category = GameOption)
		FSlateBrush GameOptionBGBrush;
	
	/*
	* CheckBox的Brush被选中
	*/
	UPROPERTY(EditAnywhere, Category = GameOption)
		FSlateBrush CheckedBoxBrush;

	/*
	* CheckBox的Brush不被选中
	*/
	UPROPERTY(EditAnywhere, Category = GameOption)
		FSlateBrush UnCheckedBoxBrush;

数据类型

UENUM()
enum class ECultureTeam : uint8 {
    
    
	EN = 0,
	ZH
};

SlAiGameOptionWidget 主要是调整显示的样式画刷和调用切换中英文的方法。
单例类SlAiDataHandle 初始化文本的语言和定义切换中英文的方法。

//中文切换
			SAssignNew(ZhCheckBox,SCheckBox)
			//SLATE_EVENT( FOnCheckStateChanged, OnCheckStateChanged )
		.OnCheckStateChanged(this,&SSlAiGameOptionWidget::ZhCheckBoxStateChanged)

//英文切换
			SAssignNew(EnCheckBox,SCheckBox)
			.OnCheckStateChanged(this,&SSlAiGameOptionWidget::EnCheckBoxStateChanged)

void SSlAiGameOptionWidget::ZhCheckBoxStateChanged(ECheckBoxState NewState)
{
    
    
	//设置被选中的框
	...
	//告诉数据控制类转换为中文
	SlAiDataHandle::Get()->ChangeLocalzationCulture(ECultureTeam::ZH);
}
void SSlAiGameOptionWidget::EnCheckBoxStateChanged(ECheckBoxState NewState)
{
    
    
	//设置被选中的框
	...
	//告诉数据控制类转换为中文
	SlAiDataHandle::Get()->ChangeLocalzationCulture(ECultureTeam::EN);
}

void SlAiDataHandle::ChangeLocalzationCulture(ECultureTeam Culture)
{
    
    
	switch (Culture)
	{
    
    
	case ECultureTeam::EN:
		FInternationalization::Get().SetCurrentCulture(TEXT("en"));
		break;
	case ECultureTeam::ZH:
		FInternationalization::Get().SetCurrentCulture(TEXT("zh"));
		break;
	}
	//赋值
	CurrentCulture = Culture;
}

ECheckBoxState 有三种状态：
未勾选
勾选
既未选中也未选中
