Problem implimenting .cpp file.

[MasterM]

Hey all, what i am trying to do is make a manager.h to declare the driver settings and options and a player.cpp to add a Iscenenode...
but for some reason i get errors like :


Main.cpp

Code: Select all

#include "manager.h"

int main(int argc, char** argv)
{

    while(device->run())
    {
        driver->beginScene(true, true, SColor(0,200,200,200));

        smgr->drawAll();
        guienv->drawAll();

        driver->endScene();
    }

    device->drop();

    return 0;
}

Manager.h

Code: Select all

#ifndef MAN_H
#define MAN_H

#include <irrlicht.h>

using namespace irr;

using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;

 IrrlichtDevice *device =
        createDevice(EDT_OPENGL, dimension2d<s32>(640, 480), 32,
            false, false, false, 0);

    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
    IGUIEnvironment* guienv = device->getGUIEnvironment();

#endif

player.cpp

Code: Select all

#include "manager.h"

ISceneNode* mar=smgr->addSphereSceneNode();

but i get erros like :

obj\Debug\src\main.o||In function `_ZN3irr4core12irrAllocatorIcE12internal_newEj':|

||=== Build finished: 4 errors, 0 warnings ===|

and when i remove player.cpp everything runs fine...
Do you guys know what the problem is?Thanks.

ISceneNode* mar=smgr->addSphereSceneNode();

This line makes absolutely no sense outside of a function. You can only execute code within a function (and thus, have to call it from main() in some way).

I would advise looking at some tutorials on classes and functions

I readed it but dont know where to use it correctly, can you give me a smal example on how to achieve what i am trying to do?
Thanks

You should rethink your initialisation (starting from main() and adding function calls from there) and consider avoiding global variables completely.

Code: Select all

#include "manager.h"

ISceneNode* mar=smgr->addSphereSceneNode();

should be something like...

Code: Select all

#include "manager.h"

void CreatePlayerNode()
{
ISceneNode* mar = smgr->addSphereSceneNode();
}

*I just woke up, so cut me some slack if this is wrong.*

you should have a look on a C++ tutorial, dude.
i recommend this one: http://www.cplusplus.com/doc/tutorial/
good luck !

Hmm thank you and i had a read on classes and functions but it still dont get everything...
How do i declare something like smgr to create objects in other class cause i tried everything but did not work or can anyone point me in the right direction of passing smgr from one class to another..thanks.

I think you're looking for inheritance.
