LWJGL Lighting

[Skatty]

Hi

Can someone explain me this source code for lighting in LWJGL? Because now it works but when i rotate camera its lighter or darker. i dont want that. i changed light position but it dont work. its still the same. how i can use that code to emit a sunlights?

// ***********&*******************************LIGHTT***************************************************///
		initLightArrays();
		glShadeModel(GL_SMOOTH);
		glMaterial(GL_FRONT, GL_SPECULAR, matSpecular);				// sets specular material color
		glMaterialf(GL_FRONT, GL_SHININESS, 50.0f);					// sets shininess
		
		glLight(GL_LIGHT0, GL_POSITION, lightPosition);				// sets light position
		glLight(GL_LIGHT0, GL_SPECULAR, whiteLight);				// sets specular light to white
		glLight(GL_LIGHT0, GL_DIFFUSE, whiteLight);					// sets diffuse light to white
		glLightModel(GL_LIGHT_MODEL_AMBIENT, lModelAmbient);		// global ambient light 
		
		glEnable(GL_LIGHTING);										// enables lighting
		glEnable(GL_LIGHT0);										// enables light0
		
		glEnable(GL_COLOR_MATERIAL);								// enables opengl to use glColor3f to define material color
		glColorMaterial(GL_FRONT, GL_AMBIENT_AND_DIFFUSE);

	private static void initLightArrays() {
		matSpecular = BufferUtils.createFloatBuffer(4);
		matSpecular.put(1.0f).put(1.0f).put(1.0f).put(1.0f).flip();

		lightPosition = BufferUtils.createFloatBuffer(4);
		lightPosition.put(World.BLOCK_AMOUNT_AT_AXIS/2).put(60.0f).put(World.BLOCK_AMOUNT_AT_AXIS/2).put(0.0f).flip();
		
		whiteLight = BufferUtils.createFloatBuffer(4);
		whiteLight.put(1.0f).put(1.0f).put(1.0f).put(1.0f).flip();
		
		lModelAmbient = BufferUtils.createFloatBuffer(4);
		lModelAmbient.put(0.5f).put(0.5f).put(0.5f).put(1.0f).flip();
