Project Crashes after Drawing the menu screen

[Zyinto]

I'm trying to draw a menu screen before loading the level of my game, The menu gets drawn and right after that the project crashes.

This is my main

Code: Select all

int lastFPS = -1;
const f32 MOVEMENT_SPEED = 15.f;
int inmenu =1;
 
int main(int argc, char** argv)
{
 
 
 
    IrrlichtDevice *device =
        createDevice(EDT_OPENGL, dimension2d<u32>(1280, 720), 16,false, false, false, &receiver);
 
    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
    IGUIEnvironment* guienv = device->getGUIEnvironment();
 
 
    guienv->addStaticText(L"Outer Space 2d! ",
        rect<int>(10,10,200,22), true);
 
 
   //driver->setFog(video::SColor(255,255,255,255),EFT_FOG_LINEAR , 5, 1, 0.01f, false,false);
 
    scene::IAnimatedMeshSceneNode* Tile[64][64];
    video::IImage* TileMapImage = driver->createImageFromFile("res/tiletest.png");
 
 
 
 
    for(int h = 0 ; h < 64; h ++ )
    {
        for(int w = 0; w < 64 ; w ++ )
        {
            video::SColor PixelColor = TileMapImage->getPixel(h,w);
 
 
                if (PixelColor == video::SColor(255,255,0,0)  )
                {
                    printf("found red\n");
 
                Tile[h][w] = smgr->addAnimatedMeshSceneNode(smgr->getMesh("res/walltile_1_180.X"));
                printf("tile loaded\n");
                Tile[h][w]->setPosition(core::vector3df(h*3,0,w*3));
                Tile[h][w]->setMaterialFlag(EMF_LIGHTING,false);
                }
 
                if (PixelColor == video::SColor(255,255,255,255)  )
                {
                    printf("found white\n");
 
                Tile[h][w] = smgr->addAnimatedMeshSceneNode(smgr->getMesh("res/floortile_1.X"));
                printf("tile loaded\n");
                Tile[h][w]->setPosition(core::vector3df(h*3,0,w*3-3));
                Tile[h][w]->setMaterialFlag(EMF_LIGHTING,false);
                }
 
                if (PixelColor == video::SColor(255,255,150,0)  )
                {
                    printf("found orange\n");
 
                Tile[h][w] = smgr->addAnimatedMeshSceneNode(smgr->getMesh("res/dungeondoor_1_180.X"));
                printf("tile loaded\n");
                Tile[h][w]->setPosition(core::vector3df(h*3,0,w*3));
                Tile[h][w]->setMaterialFlag(EMF_LIGHTING,false);
                }
        }
    }
 
 
 
    CameraLookAt = vector3df(0,2,0);
    CameraPos = vector3df(0,2,10);
 
 
 
    while(device->run())
    {
        do{
        TitelScreen(driver,smgr);
        if(receiver.IsKeyDown(irr::KEY_RETURN))
            {
            inmenu = 0;
            printf("Enter\n");
            }
        }while(inmenu==1);
 
        //core::vector3df nodePosition = node->getPosition();
 
        ICameraSceneNode * MainCam = smgr->addCameraSceneNode(0,CameraPos, CameraLookAt);
        MainCam ->setFarValue(40.f);
 
        player.Handle();
 
 
        // drawing of the scene
        //driver->beginScene(true, true, video::SColor(255,113,113,133));
 
 
 
        //smgr->drawAll(); // draw the 3d scene
        // hier staat de nieuwe image draw
 
 
 
        //driver->endScene();
 
        int fps = driver->getFPS();
 
        if (lastFPS != fps)
        {
            core::stringw tmp(L"Movement Example - Irrlicht Engine [");
            tmp += driver->getName();
            tmp += L"] fps: ";
            tmp += fps;
 
            device->setWindowCaption(tmp.c_str());
            lastFPS = fps;
        }
    }
 
    device->drop();
 
 
    return 0;
}
 

and this is my gamescreens with the function titlescreen which draws the menu.

Code: Select all

void TitelScreen(IVideoDriver* menudriver,ISceneManager* menusmgr){
    printf("Crash\n");
    video::ITexture* menu = menudriver->getTexture("Screens/menu.png");
    printf("Crash2\n");
 
 
    menudriver->beginScene(true, true, video::SColor(255,113,113,133));
    menudriver->makeColorKeyTexture(menu, core::position2d<s32>(0,0));
    menusmgr->drawAll();
    menudriver->draw2DImage(menu, core::position2d<s32>(0,0));
    menudriver->endScene();
 
}
 

and as I mentioned earlier the menu does get drawn but for some reason it crashes almost instantly after it has been drawn.

You are creating a new camera every frame

[jiangcaiyang]

Check for pointers, it often invokes methods with empty pointer. Be careful.

Because title screen is called in a loop and you create a new image inside title screen you are creating a new image every frame. Create the image only once and then use the single instance over and over in the loop. Same thing with the camera

Thanks this was indeed my problem fixed it now!
