将SlAiNewGameWidget插入菜单控件

//将SSlAiNewGameWidget插入ContentBox

处理存档名

初始化存档名为空
SlAiDataHandle.h

public:
//存档名
	FString RecordName;

SlAiDataHandle.cpp

SlAiDataHandle::SlAiDataHandle()
{
    
    
	//初始化存档数据
	InitRecordData();
}





void SlAiDataHandle::InitRecordData()
{
    
    
	RecordName = FString("");
	
}
