Instantiating Objects in pure C++? Constructor code not being called. But is having some effect

Question

I'm writing C++ code in order to practice and learn for myself only. But I am having trouble instantiating one of my custom objects.

I'll try to be brief in my explanation here (but also trying not to miss necessary details): Game is Text-Only. Dungeon class is the class I have trouble creating instance of. I also have a 'Game' class (when the Game class is instantiated, the results are as I expected).

In my Dungeon constructor I put a cout with some log info. But it never prints. However the initialization code within the same code block all appears to have happened. (I know this because if I call a function to print the value of one of its variables I can see that it has indeed been populated with the data).

(The line inside the Game() constructor which calls the Debug_PrintRaw() function, this gives the desired result which implies to me that the constructor Dungeon(string filename) is called, because the string is converted from the file at that moment and it has worked the full string (the contents of the file) are printed. But none of the LOG parts are printed. (I expected them to get printed as soon as the game starts, since at the moment Game is spawned, it should spawn a Dungeon also.

So the total project code isn't too large, its just started so I will post it all here (the code is probably very stupid and overblown because I don't always know what I am doing!):

(thanks for any help)

Answer 1

OK well the answer turned out to be simple. As per the comments I was clearing the screen and hence my outputs with "LOG: xxxxx" were being cleared with it. I was stupidly expecting to magically still see them.

So the simple fix was not to clear the screen, then I could see all the log.

But of course I want to be able to clear the screen also, so this highlights to me the need for some output 'log' file(s). So the simple fix becomes a new can of worms ;)

Well I am very much a noobie and this is just how I personally implemented that logfile output. This consists of (optionally) getting the date/time using ctime_s, as well as using #include <fstream>

In the Game.h I added this variable and function:

std::ofstream log_debug
void WriteToLog_Debug(std::string);

in Game.cpp they are implemented as follows:

Game::Game()
{
   log_debug = std::ofstream("give_it_any_file_name.txt");
   WriteToLog_Debug("Log file created");
}

void Game::WriteToLog_Debug(std::string message)
{
    time_t t = time(NULL);
    char timeStr[26];
    ctime_s(timeStr, sizeof(timeStr), &t);

    timeStr[sizeof(timeStr) -2] = '\0';
    log_debug << timeStr << ":    " << message << std::endl;
}

The function looks a little complicated but much of that is just getting the time, and then removing the newline char from that string it gives us.

I hope this might help someone who reads this some day. :D Have fun
