This tutorials are based on the irrlicht tutorial, show how to set up IDE for suing Irrlicht Engine. Let’s start with “Hello World”.
include the header file, and use irr namespace
#include <irrlicht.h>
using namespace irr;
To use the Irrlicht .DLL file, we need to link with the Irrrlicht.lib, you could do it easily in Visual Studio Property Linker, or you could do the following steps:
#ifdef _IRR_WINDOWS_
#pragma comment(lib, "Irrlicht.lib")
#pragma comment(linker, "/subsystem:windows /ENTRY:mainCRTStartup")
#endif
Then it’s our main part.
We create a device.
/* use EDT_SOFTWARE as device type, windows size is (640, 480), amount of color bits per pixel is 16. */
IrrlichtDevice *device =
createDevice( video::EDT_SOFTWARE, dimension2d<u32>(640, 480), 16,
false, false, false, 0);
if (!device)
return 1;
Set the caption of the windows
device->setWindowCaption(L"Hello World! - Irrlicht Engine Demo");
Get a pointer to the VideoDriver, the SceneManager and the graphical user interface environment
IVideoDriver* driver = device->getVideoDriver();
ISceneManager* smgr = device->getSceneManager();
IGUIEnvironment* guienv = device->getGUIEnvironment();
Add a hello world label to the window, using the GUI environment. The text is placed at the position (10,10) as top left corner and (260,22) as lower right corner.
guienv->addStaticText(L"Hello World! This is the Irrlicht Software renderer!", rect<s32>(10,10,260,22), true);
In order to get interesting, we use the mesh from the scene manager and then add a scenenode to display it with addAnimatedMeshSceneNode(). In the mean time, check it.
IAnimatedMesh* mesh = smgr->getMesh("../../media/sydney.md2");
if (!mesh)
{
device->drop();
return 1;
}
IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );
Change its material to make it nicer, We disable lighting because we do not have a dynamic light in here, and the mesh would be totally black otherwise. Then we set the frame loop, such that the predefined STAND animation is used. And last, we apply a texture to the mesh.
if (node) {
node -> setMaterialFlag(EMF_LIGHTING, false);
node -> setMD2Animation(scene::EMAT_STAND);
node->setMaterialTexture( 0, driver->getTexture("../../media/sydney.bmp") );
}
Place a camera into the position (0, 30, -40), target is at (0,5,0)
smgr -> addCameraSceneNode(0, vector3df(0, 30, -40), vector3df(0, 5, 0))
Let’s draw Everything.
while(device->run()) {
driver -> beginScene(true, true, SColor(255, 100, 101, 140));
smgr -> drawAll();
guienv -> drawAll();
driver -> endScene();
}
After we are done, we have to delete the Device and every object you created.
device -> drop();
return 0;
