Creating a cube

[zapakitul]

Hey guys, i went over some Irrlicht tutorials and decided to try and write a small app that displays a cube on the screen. The code i have written compiles but the cube isn't displayed, and even though i tried changing it's position the screen goes eighter black, or stays blue.... Any idea where the problem could be?

Code: Select all

 #include <Irrlicht.h> 
#pragma comment(lib, "Irrlicht.lib"); 


 using namespace irr;
 using namespace core;
 using namespace scene;
 using namespace video;
 using namespace gui; 


int main()
{

 IrrlichtDevice *device = createDevice(EDT_OPENGL);
 IVideoDriver* video = device->getVideoDriver();
 ISceneManager* smgr = device->getSceneManager();

 ISceneNode* cube = smgr->addCubeSceneNode();
 cube->setPosition(vector3df(0,0,0));
 

 while(device->run() && device)
 {
  video->beginScene(true, true, video::SColor(255,0,0,255));
  smgr->drawAll();
  video->endScene();
 }

} 

Also, i have just moved to Irrlicht from DarkGDK and i am eager to port my project. Right now i am trying to get a hand on the basics and then work on it. My first question would be, how do i get an object position on the X, Y or Z scale? In GDK it was

Code: Select all

dbGetObjectPositionX(objectNumber);

in Irrlicht i position the object using cube->setPosition(vector3d(x,y,z)), but how do i get it's position? Thank you.

You are not seeing the cube in your window because you have not created a camera to look at your cube.

Also to get position you do it exactly like you set...

Code: Select all

vector3df cubepos = cube->getPosition();

then to set the position based on what you got...

Code: Select all

cube->setPosition(cubepos);

Ups silly me, forgot the camera!
Btw what if i want to get the X position, and then position the cube like
Cube Position X+1, cube Position Y, Cube Position Z?

Remember that Vector3df is a class containing 3 arguments so to specify either the X, Y, or Z you can access the subclass by using the

Code: Select all

campos.X

for the X coordinate and so forth

Code: Select all

vector3df cubepos=getPosition();
cube->setPosition(vector3df(cubepos.X+1, cubepos.Y,cubepos.Z));

thank you alpha.
