That's a good idea, I'll try that at some point,
 but the rest of this week is going to be pretty packed.
Finals are upon me.
I have no idea how this will work out.

[Alexhans]

crap man... I feel I'm missing when my nephew starts walking... Those pics look awesome...

I'll be here... soon... I promise... 

[Outcast Orange]

We are waiting for you Alex. This place is where we all belong.
Bay12 is our ship, on this ocean of dooms.

Also, migraine.

[Outcast Orange]

Tomorrow is a definitive day.

If tomorrow is a bad day,
things will collapse, and I very well may cease to be Orange.

If tomorrow is a good day,
I will have 3 weeks of free time to enjoy programming my game.

I guess you guys can cross your fingers,
 but at this point I'm very nervous.

I hope it all works out.

[Outcast Orange]

Okay, nothing is nearly as bad as I first thought.
Tomorrow's the last day I'll be busy for a long time,
 so after that, I should be free to work on my game without issue.

Ooh, I can't wait to get it all together.

Sounds good, looking forward to it!

[Outcast Orange]

I cannot wait for tomorrow evening!
I will be completely, completely free!

I'll have to try and get my MSN working before then I guess.  I may have to set it up on my PS3 though, I've only got my dad's laptop in the morning and afternoon, while he's working.  Once he get's back he usually needs it for school stuff...

[Jack_Bread]

Huzzah! Awesome!

I've started work on my game again, but things are going slowly.
The problem with saving and loading maps,
is all of it is a big headache, since you basically have to juggle all the info in and out of the save files,
which at the moment are only 78 KB height maps, and the bugs are so vague and confusing.

I feel like I'm drowning in my game.
The bugs will suffocate me dead.

[timmeh]

Stick with it!  What kind of bugs, anything I (or anyone else here) could help with?

[Outcast Orange]

You would only be able to help if you were willing to dive deep into a headache tarantula soup.

The problems are mostly to do with having tons of functions that all allow you to specify parameters,
but the parameters are all different systems,
 and nothing is consistent, and saving and loading are difficult to test.

I'll feel better about it later.
I just need a fresh head to think about all of this clearly.

For some reason I thought today would be all roses and crayons.

I've made a couple more tiny steps in the right direction, but massive issues all around.
I don't even know where to start. I suppose I'll keep poking the parts of the code that aren't working,
until I learn enough about the issue to resolve it.

Until then, I can't do any of the fun stuff that is to be added next.
I am getting very impatient and aggravated.

The current problem is very vague.
When a new map tile is explored, it is supposed to check if a save of that map already exists, and if so,
just load the save.
Too bad it doesn't work, and I have no idea where the problem lies.

The most likely issue is that the detection of the existence of files is not working.
Here's the code that deals with that:

Spoiler (click to show/hide)

Code: [Select]

    stringstream awayfile;
    awayfile << "Away" << " " << worldx << " " << worldy << " " << worldz << ".bin";
    ifstream myFile;
    bool hasloaded = false;
    myFile.open(awayfile.str().c_str(), ios::trunc | ios::in | ios::binary);
    if(myFile){
        myFile.read((char*)&myaway, sizeof (AwayData));
        myFile.close();
        hasloaded = true;
    }


The overall issue is that it isn't detecting the maps present, and is creating a new map on top of the old one.

The other place the issue could be is in the translation of coords in my map transfer function.
Basically, if the game is moving the world map around incorrectly, it could be picking up empty spaces there.
I would have to identify and fix that problem on my own, as I have been attempting to do for a while.

Basically, if you want to help, proof-read that code, and tell me if it makes sense to you.

It all looks like it should work to me.  If checking for the file's existance is the issue though, here's the code I use in my game for it:

Code: [Select]

/**file_exists(string filename)
Returns true if the file exists
Uses 'sys/stat.h', hopefully multiplatform
'fileinfo' can be used to get more information if I need it later.**/
bool file_exists(string filename)
{
    struct stat fileinfo;  //A variable to hold the more complicated result of stat()

    if( stat(filename.c_str(), &fileinfo) == 0 )  //If stat() returns 0 then the file exists
    {
        return true;  //so return true
    }
    else  //If it returned anything else, then the file can't be access for some reason, it may not exist.
    {
        return false;  //so return false
    }
}
Just make sure you include sys/stat.h and it should work just fine.  If you Google 'stat() C++' you can probably figure out more about the 'fileinfo' variable.  From what I remember it'll let you know exactly what happened when it tried to open the file somehow.

You could use the C file system, since it only returns a valid file pointer if the file exists(IIRC), and then close the file and use the C++ method, now knowing that the file exists...

What does ios::trunc mean? Could it imply being able to write to the file?

Yes, it appears so!

"ios::trunc: If the file does not exist, a new empty file is created. If the file exists, its content is deleted and it is treated as a new file. "

The issue is the ios::trunc.
