}
long startp = dstFile.tellp();
dstFile.write((char *)&gfxData, sizeof(GRAPHIC_DATA)); // temp - THIS IS WRITING 61 BYTES WHEN GRAPHIC_DATA is 60 ?!
// temp
// these should be equal, and they are for Potion, the one with a gdf file
// if you remove the gdf file it stops working and any you add one too
// start to work
// why does having a gdf file making it work and not having one break it
long tellpp = dstFile.tellp();
if (tellpp != sizeof(GRAPHIC_DATA))
{
std::cout << "ERROR: " << tempFileName << " [" << tellpp << " / " << sizeof(GRAPHIC_DATA) << "] : " << startp << std::endl;
while(1);
}
// end temp
dstFile.write((char *)image.getImageData(), image.getSize());
dstFile.close();
return tempFileName;
}
The problem is, the line
dstFile.write((char *)&gfxData, sizeof(GRAPHIC_DATA));
After calling this I check the the position with tellp and it ends up 1 position ahead of where it should be (i think).
The weird thing is, this write only goes 1 position past IF I have a .gdf file (just a basic file with some info).
The output ill get is
ERROR: temps/Attribute_Damage.tmp [61/60] : 0
And this error is for all files where ReadGDFFile doesnt open anything. Here is the source to that incase
void ReadGDFFile(const std::string & filename, int & frames, int & frameDelay, int & frameWidth, int & frameHeight)
{
std::string gdfFilename = filename;
size_t end = gdfFilename.find_last_of(".");
if (end == std::string::npos)
{
std::cout << "ERROR: Invalid file name" << std::endl;
while(1);
}
gdfFilename = gdfFilename.substr(0, end + 1) + "gdf";
std::ifstream gdfFile(gdfFilename);
if (gdfFile.is_open())
{
std::string option;
while (gdfFile.eof() == false)
{
gdfFile >> option;
if (option == "frameDelay")
{
gdfFile >> frameDelay;
}
else if (option == "frameWidth")
{
gdfFile >> frameWidth;
}
else if (option == "frameHeight")
{
gdfFile >> frameHeight;
}
else
{
std::cout << "Unknown GDF attribute name: " << option;
while(1);
}
}
gdfFile.close();
}
}
const int MAX_GFX_NAME = 32;
#pragma pack(push, 1)
struct GRAPHIC_DATA
{
char m_handle[MAX_GFX_NAME];
int m_frames;
int m_frameDelay;
int m_frameWidth;
int m_frameHeight;
int m_textureWidth;
int m_textureHeight;
int m_textureSize;
};
#pragma pack(pop)
The thing is Im not sure how anything changes how much data is written. sizeof(GRAPHIC_DATA) should always be the same.
Please ask if you need more info. I have attached the source.
To test, compile, then drag and drop the "files" folder onto the exe in the debug folder.
Thanks for any help.
