I can't get lighting to work

I have a 3d maze with collision detection but i want to add some lights (I''m using OpenGL MFC). I used this code in InitGL(): glLightfv(GL_LIGHT1,GL_AMBIENT,ambient); glLightfv(GL_LIGHT1,GL_DIFFUSE,diffuse); glLightfv(GL_LIGHT1,GL_POSITION,position); glEnable(GL_LIGHT1); glEnable(GL_LIGHTING); But it still doesn''t work, what could be wrong?

for(int i=0;iglEnable(i);
}

The maximum amount of lights you can get in OpenGL 1.1 is 8. So
if you will #define LIGHTS 100 it won''t help you.

Yes but i''m sure i''m not drawing over 8 lights at the time. This is too confusing for me, got to check some tutorials for portals i think...

Also, you need to use the offset from GL_LIGHT0 when you enable your lights. So, instead of:

glEnable(i)

use:

glEnable(GL_LIGHT0+i)
