Hello there,
-- First of all, I don't know whether the vector can be called as a "global vector" if I declared it under a namespace, but not in a class or function. --
I'm now writing a simple Irrlicht (http://irrlicht.sourceforge.net) wrapper for my game to make things simpler and easier, but recently I got an "Access violation reading location" error when trying to push_back a vector declared in the global scope.
Here is my code so far:
irrwrap.cpp:
namespace irrw
{
//.........
IrrlichtDevice *device;
IVideoDriver *driver;
irr::core::array<irr::video::ITexture*> TextureCollector;
vector<int> TextureConnector;
//.........
}
//..............
void irrInit(int iGraphicsDriver, int iWindowWidth, int iWindowHeight, int iScreenDepth, bool bFullScreen)
{
E_DRIVER_TYPE drvT;
if(iGraphicsDriver == GD_SOFTWARE)
drvT = EDT_SOFTWARE;
else if(iGraphicsDriver == GD_D3D8)
drvT = EDT_DIRECT3D8;
else if(iGraphicsDriver == GD_D3D9)
drvT = EDT_DIRECT3D9;
else if(iGraphicsDriver == GD_OPENGL)
drvT = EDT_OPENGL;
//..............
irrw::device = createDevice(drvT, dimension2d<u32>(iWindowWidth, iWindowHeight), iScreenDepth, bFullScreen);
irrw::driver = irrw::device->getVideoDriver();
//..................
}
void irrLoadImage(irr::core::stringc szFileName, int iID, int iTextureFlag)
{
//........
irrw::TextureCollector.push_back(irrw::driver->getTexture(szFileName)); // the call stack pointed to this line
irrw::TextureConnector.push_back(iID);
}
main.cpp:
//.........
INT WINAPI WinMain(HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT)
{
//.........
irrInit(GD_OPENGL, 800, 600, 16, false);
irrLoadImage("picture.jpg", 100, 1);
//.........
}
and the error:
Unhandled exception at 0x692804d6 in Game.exe: 0xC0000005: Access violation reading location 0x00000558.
Now I really got no idea on how to fix the problem.
Any kind of help would be appreciated :)
Here are some prototypes:
virtual ITexture* getTexture(const io::path& filename) = 0;
typedef core::string<fschar_t> path; // under 'io' namespace
typedef char fschar_t;
typedef string<c8> stringc;
typedef char c8;
Just FYI, I am using MSVC++ 2008 EE.
(CODE UPDATED)
