Irrlicht Engine

If you add light to scene and want it to affect objects, this objects must have materials with lighting enabled; like: node->setMaterialFlag(EMF_LIGHTING, true);

I know, i set it true.

I have this:

ILightSceneNode* light = smgr->addLightSceneNode(0);
SLight sw;
sw.CastShadows = true;
sw.Position = vector3df(0, 0, 50);
sw.Direction = vector3df(0, 0, -10);
sw.Radius = 700;
sw.Type = ELT_DIRECTIONAL;
light->setLightData(sw);

But it doesn't work :/

How to program in C++
----------------------------
1] Use a lot of global varibles
2] Give them mysterious names such as: X67, i_gcl or Horace
3] Write everything in one big file. h
4] Implement the entire program at once.
5] Use macros, in order to emulate Pascal.
6] Assume that the compiler will ...

So what i have to do to get light from one side?

I don't want to make new topic so:

I want to add some light in my app. There is a code. My question is: why triangle is light from all sides? I changed position of light, but nothing happen.

Yea, now is ok. But if i will do some copies (like in code on this site )i can delete only last one. So how i can delete ALL(now i have this )
Btw. Why:

virtual bool IsKeyDown(EKEY_CODE keyCode){
bool rrrr = KeyIsDown[keyCode];
KeyIsDown[keyCode] = false;
return rrrr;
}
no:(that is in ...

#include <irrlicht.h>

bool start=false;
bool zeruj=false;

Nie, nie o to mi chodziło :/

Aek give me your Gygy number i'll explain what i want

I want to do a block rotation. I have model of triangle and i rotate it. But i don't get that i want. I want something like this:

i get this:

I solved the problem. In tutorial on irrlicht main site wasn't that one more thing you have to do. Now all's fine.

Btw.In this forum you always try to help. In polish forums it's harder to get help ;p

I have downloaded irrlicht 1.7 from main page. For path- I don't think so(in dev you have button to select path so all looks correct)(i you want i can do screen shots).

Yea

All was fine, but today i instaled dev with wxwidgets. After i uninstaled it and now i can't do new projects with irrlicht. Old ones compile and run fine, but now no. I get message like:
[Linker error] undefined reference to `_imp___ZN3irr12createDeviceENS_5video13E_DRIVER_TYPEERKNS ...

Well, i export to b3d and finally all works fine (without colors, but i will use textures)

Anyone help?
