I'm new and i have problem. I try to load my pk3 file, but i see only grey window. It's code:

#include <irrlicht.h>

using namespace irr;
using namespace core;
using namespace scene;
using namespace video;

int main()

{ 
  IrrlichtDevice* device = createDevice( EDT_OPENGL, dimension2d<s32>(800, 600),
  32, false, false, false, 0);
	IVideoDriver* driver = device->getVideoDriver();
	ISceneManager* smgr = device->getSceneManager();
 
	device->setWindowCaption(L"Test");//nagłówek okna


	device->getFileSystem()->addZipFileArchive("test.pk3");
	IAnimatedMesh* mesh = smgr->getMesh("test.bsp");
    ISceneNode* node = 0;
        
        if (mesh)
                node = smgr->addOctTreeSceneNode(mesh->getMesh(0), 0, -1, 1024);
              node = smgr->addMeshSceneNode(mesh->getMesh(0));
	  smgr->addCameraSceneNodeFPS(); 
	      device->getCursorControl()->setVisible(false); 
	  
	 int lastFPS = -1;

        while(device->run())
        {
                if (device->isWindowActive())
                {
                        driver->beginScene(true, true, SColor(255,200,200,200));
                        smgr->drawAll();
                        driver->endScene();

                        int fps = driver->getFPS();

                        if (lastFPS != fps)
                        {
                                stringw str = L"Irrlicht Engine - Quake 3 Map example [";
                                str += driver->getName();
                                str += "] FPS:";
                                str += fps;

                                device->setWindowCaption(str.c_str());
                                lastFPS = fps;
                        }
                }
                else
                        device->yield();
        } 

	}

In consol is somthing like this:Needed 0ms to create OctTree SceneNode.(0 nodesm o polys)

Sounds like it loaded correctly, it may be that it didn't load the textures or that the model is offscreen.

I used textures form GTKRadiant(specifically-quake3), but i haven't they in my pk3. May it's problem?(i thought, in pk3 must be only myself textures)

Btw. what is 4th argument in " node = smgr->addOctTreeSceneNode(mesh->getMesh(0), 0, -1, 1024);"

Posted: **Sat Mar 06, 2010 6:59 pm**

minimalPolysPerNode. Every part of the oct tree has to have at least that many I'm guessing, so if you lower it there will be more sections.

Ok, but what can i do this scene load correctly? You said code is ok.
When i compiled test.map into bsp(by Q3Map2, 11th option) i get tes.:
bsp,bak,prt and srf. I have these files in Maps(Script are empty). I did zip file and changed name into pk3. Something wrong? Why this not working

Did you try loading it in example 09 (meshviewer) or example 21 (Quake3Explorer)?

Posted: **Mon Mar 08, 2010 6:14 pm**

Yes, but i can't compil it. There are always some errors :/
For example(02.Quake3Map):I have error in

Code: Select all

IrrlichtDevice *device =
		createDevice(driverType, core::dimension2d<u32>(640, 480));

When i write

Code: Select all

IrrlichtDevice *device =
		createDevice(driverType, core::dimension2d<s32>(640, 480));

There is new error(129 'class irr::scene::ISceneManager' has no member named 'addOctreeSceneNode' ).In

Code: Select all

	node = smgr->addOctreeSceneNode(mesh->getMesh(0), 0, -1, 1024);

Go to bin\win32-visualstudio, there are precompiled binaries in there

It should be "OctTree" instead of "Octree", assuming you're using an older version of Irrlicht like 1.6... Newer versions call them "Octree"

Always use the examples which come with the Irrlicht download. The sources are in the examples folder and the Windows executables are,as ent1ty mentioned, in the bin folder.

But i used it! I have Irrlicht 1.7 and this code is from example/

May it's dev cpp fault

Posted: **Tue Mar 09, 2010 8:56 am**

Yes, example is correct. However, you're using 1.6 or older headers. This won't work ever.

Posted: **Tue Mar 09, 2010 5:24 pm**

Uh, sorry i forget i have two verison of irrlicht. In dev i have instaled 1.4 and example is from 1.7. My fault, sorry.

So i used exemaple 2 feom irrlicht 1.4. My application run but again there is only grey window.

Maybe wrong paths, incorrect dlls, or whatever. Without a proper information we cannot judge this from here.
