I'm playing around with openGL but when I call glLight() it always puts the light in seemingly the same spot no matter what I put the values at. I am assuming the float array is [x, y ,z, ?] I'm not sure what the last value is either. Could someone give me some clarification?

void glLightf( GLenum light, GLenum pname, GLfloat param);

Oh sorry, you were looking for the values in the 'param'. ughh. I should probably learn not to post and regret 5 seconds after posting.

I do not see glLight on the reference...

I'm using lwjgl if it makes a difference (but it shouldn't). Here is what I'm doing atm. glLight(GL_LIGHT0, GL_POSITION, (FloatBuffer) BufferUtils.createFloatBuffer(4).put(x).put(y).put(z).put(1.0f).flip()); x, y and z are the positions of the camera. I've tried pushing the matrix. not pushing the matrix, everything and it always seems to be in the same spot. The light also seems to light a huge area. And yes the light I'm creating is Light0.

You shouldn't be using the fixed-function renderer.

I'm still learning how to openGL.
