Your rectangle to display the image in has an area of 0.
Try something more like (0,0,500,500), that gives you a rectangle 500x500

Also, what you're doing by the looks of your code is calling draw (which will draw the image for one frame only) and then removing it straight away. So basically it will never show up for more than a tiny split second i should think.
You need to draw it in a loop, for example you may want to time it to draw for a certain number of seconds or something.

its works now , i add a other code .
this code is for allegro , you need allegro SDK
Code: Select all
BITMAP *my_pic = NULL; //Declare a BITMAP called my_pic
my_pic = load_bitmap("screens\\Loginscreen.bmp", NULL);
blit(my_pic, screen, 0,0,0,0,1280,1024); //Draw from 0,0 to 50,50 on the screen at (0,0)
blit(my_pic, screen, 50,50,100,100,150,150); //Draw from 50,50 to 150,150 on the screen at (100,100) release_screen();
release_screen();
rest(2000);
/* and then shut down. */
destroy_bitmap(my_pic); //Release the bitmap data

Yeah for that code, but it's not necessary. I presume Allegro is an extra library or something. Irrlicht can do it just fine, all you need is the right understanding and code to do it.

Hmm, that code shows a bitmap for 2 seconds in Allegro, not how to make a loading screen in Irrlicht.
for drawing a 2D bitmap, you could simply read the tutorials-
http://irrlicht.sourceforge.net/tut006.html
For a true loading screen, I'd do something like this
Code: Select all
bool finishedLoading = false;
s32 count=0;
while ( !finishedLoading)
{
// update the loading screen by drawing a bitmap like in tutorial 6
...
// load the next thing
finishedLoading = loadNextThing(count);
count++;
}
obviously you'd need to make your own loadNextThing function and have it load stuff up

its dont works with the Irrlicht code .
Code: Select all
bool finishedLoading = true;
s32 count=0;
while ( !finishedLoading)
{
// update the loading screen by drawing a bitmap like in tutorial 6
video::ITexture* images = driver->getTexture("Loginscreen.bmp");
driver->makeColorKeyTexture(images, core::position2d<s32>(0,0));
// finishedLoading = loadNextThing(count);
count++;
}

You should place Loading_Img->draw(); inside beginScene and endScene and not in the place you load the image.

does it schould be like this ?
Code: Select all
gui::IGUIImage * Loading_Img;
Loading_Img = guienv->addImage(rect<int>(0,0,0,0));
Loading_Img->beginScene( driver->getTexture(" testscreen.bmp));
Loading-Img->endScene( driver->texture(" eindescreen.bmp));
Loading_Img->draw();
Loading_Img->remove();

No, it has to be drawn before ending the drawing of the scene:
Code: Select all
driver->beginScene(true, true, SColor(0, 128, 128, 112));
Loading_Img->draw();
driver->endScene();
And remove the image first when the whole loading process is done...
