I am using 1.5. This issue made me crazy. I tested it in the helloword example. It doesn't work. see below:
Code: Select all
smgr->addCameraSceneNode(0, vector3df(0,30,-40), vector3df(0,5,0));
SMaterial m;
m.Lighting = false;
driver->setMaterial(m);
driver->setTransform(video::ETS_WORLD, core::matrix4());
driver->draw3DLine(vector3df(-100,5,0),vector3df(100,5,0),video::SColor(255,255,255,255));

Doesn't work means what ?
Is the line drawn wrong, or is it not drawn?

how/when do you call it ???
it works for me this way:
Code: Select all
SMaterial m;
m.Lighting = false;
while(device->run()){
driver->beginScene(true, true, video::SColor(0,0,0,0));
smgr->drawAll();
guienv->drawAll();
driver->setMaterial(m);
driver->setTransform(video::ETS_WORLD, core::matrix4());
driver->draw3DLine(vector3df(-100,5,10),vector3df(100,5,10));
driver->endScene();
}

}
I call it before the loop.

That's wrong. You need to call it between
