[aburt11]

hey there,
my irrlicht game engine is off to a bad start.
i dont understand why it is giving me an unhandeled exception at runtime. any thoughts?

main.h

Code: Select all

 
#ifndef MAIN_H_
#define MAIN_H_
 
#include <irrlicht.h>
 
using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;
 
 
//globals
 
class RedNovember
{
public:
        RedNovember();   // constructor
        void initIrrlicht();
        void renderScene();
        int shutdown();
        IrrlichtDevice* getDevice() { return device; }
private:
        IrrlichtDevice* device; 
        IVideoDriver* driver;
        ISceneManager* smgr;
        IGUIEnvironment* guienv;
 
        // every other global you would need can instead of being global just be put in here. 
          
};
 
 
#endif
 

main.cpp

Code: Select all

 
#include "main.h"
 
RedNovember* sys;
 
void RedNovember::renderScene()
{
        while(device->run())
        {
                driver->beginScene(true,true,SColor(255,100,101,140));
                smgr->drawAll();
                guienv->drawAll();
                driver->endScene();
        }
}
 
int RedNovember::shutdown()
{
        device->drop();
        return 0;
}
 
int main()
{
        sys->initIrrlicht();
 
 
        sys->renderScene();
 
        sys->shutdown();
 
}
 

initialize.cpp

Code: Select all

 
#include "main.h"
 
 
void RedNovember::initIrrlicht()
{
        device = createDevice(EDT_OPENGL, dimension2d<u32>(800, 600), 32,
                false, false, false, 0);
 
        device->setWindowCaption(L"Project: Red November");
 
        driver = device->getVideoDriver();
        smgr = device->getSceneManager();
        guienv = device->getGUIEnvironment();
 
}
 
please help :)

You never seem to create an object for your RedNovember class. So in your first call "sys->initIrrlicht();" you tell the compiler that sys points to a valid object, while in reality you never initialized sys and it only points into a random place in memory.

Classes are only descriptions of the structure. You still have to create actual objects in memory, for example with "new" to create it on the heap.

Error 1 error LNK2001: unresolved external symbol "class redNovember SYS" (?SYS@@3VredNovember@@A) C:\Users\adam\documents\visual studio 2010\Projects\RedNovember\RedNovember\main.obj

Code: Select all

int main()
{
        sys = new RedNovember();
        sys->initIrrlicht();
 
 
        sys->renderScene();
 
        sys->shutdown();
 
}

You declared but never implemented the constructor. So it's missing in the obj files.
