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(true,true,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));
}
//Activate camera4
smgr->setActiveCamera(camera[3]);
//Draw scene
smgr->drawAll();
driver->endScene();
/*
As you can probably see, the image is rendered for every
viewport seperately. That means, that you'll loose much performance.
Ok, if you're aksing "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 arround 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)
{

core::stringw tmp = L"Irrlicht SplitScreen-Example (FPS: ";

device->setWindowCaption(tmp.c_str());
}
}
//Delete device
