-A tutorial by Max Winkel.

-In this tutorial we'll learn how to use splitscreen (e.g. for racing-games)
-with Irrlicht. We'll create a viewport divided
-into 4 parts, with 3 fixed cameras and one user-controlled.

-Ok, let's start with the headers (I think there's

-There wasn't much new stuff - till now!
-Only by defining four cameras, the game won't be splitscreen.
-To do this you need several steps:
- - Set the viewport to the whole screen
- - Begin a new scene (Clear screen)
-
- - The following 3 steps are repeated for every viewport in the splitscreen
- - Set the viewport to the area you wish
- - Activate the camera which should be "linked" with the viewport
- - Render all objects
-
- - If you have a GUI:
- - Set the viewport the whole screen
- - Display the GUI
- - End scene
-
-Sounds a little complicated, but you'll see it isn't:
-*/
-
- while(device->run())
- {
- //Set the viewpoint to the whole screen and begin scene
- driver->setViewPort(rect<s32>(0,0,ResX,ResY));
- driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, SColor(255,100,100,100));
- //If SplitScreen is used
- if (SplitScreen)
- {
- //Activate camera1
- smgr->setActiveCamera(camera[0]);
- //Set viewpoint to the first quarter (left top)
- driver->setViewPort(rect<s32>(0,0,ResX/2,ResY/2));
- //Draw scene
- smgr->drawAll();
- //Activate camera2
- smgr->setActiveCamera(camera[1]);
- //Set viewpoint to the second quarter (right top)
- driver->setViewPort(rect<s32>(ResX/2,0,ResX,ResY/2));
- //Draw scene
- smgr->drawAll();
- //Activate camera3
- smgr->setActiveCamera(camera[2]);
- //Set viewpoint to the third quarter (left bottom)
- driver->setViewPort(rect<s32>(0,ResY/2,ResX/2,ResY));
- //Draw scene
- smgr->drawAll();
- //Set viewport the last quarter (right bottom)
- driver->setViewPort(rect<s32>(ResX/2,ResY/2,ResX,ResY));

- //Draw scene

- /*
- As you can probably see, the image is rendered for every
- viewport separately. That means, that you'll loose much performance.
- Ok, if you're asking "How do I have to set the viewport
- to get this or that screen?", don't panic. It's really
- easy: In the rect-function you define 4 coordinates:
- - X-coordinate of the corner left top
- - Y-coordinate of the corner left top
- - X-coordinate of the corner right bottom
- - Y-coordinate of the corner right bottom
-
- That means, if you want to split the screen into 2 viewports
- you would give the following coordinates:
- - 1st viewport: 0,0,ResX/2,ResY
- - 2nd viewport: ResX/2,0,ResX,ResY
-
- If you didn't fully understand, just play around with the example
- to check out what happens.
-
- Now we just view the current fps and shut down the engine,
- when the user wants to:
- */
- //Get and show fps
- if (driver->getFPS() != lastFPS)
- {
- lastFPS = driver->getFPS();
- core::stringw tmp = L"Irrlicht SplitScreen-Example (FPS: ";
- tmp += lastFPS;
- tmp += ")";
- device->setWindowCaption(tmp.c_str());
- }
- }
- //Delete device
- device->drop();
- return 0;
-}
-/*
-That's it! Just compile and play around with the program.
-Note: With the S-Key you can switch between using splitscreen
-and not.
