I''m pretty new to open gl and c++, so if you can keep it simple. I decided to try making a flashlight program, and I want a specular light source to point out the end of my flashlight (pretty obvious), but I''m not to sure how to do it. If anyone wants to take a look at this code, I''d appreciate - thanks: #include // Header File For Windows #include // Header File For Standard Input/Output #include // Header File For The OpenGL32 Library #include // Header File For The GLu32 Library #include // Header File For The Glaux Library HDC hDC=NULL; // Private GDI Device Context HGLRC hRC=NULL; // Permanent Rendering Context HWND hWnd=NULL; // Holds Our Window Handle HINSTANCE hInstance; // Holds The Instance Of The Application bool keys[256]; // Array Used For The Keyboard Routine bool active=TRUE; // Window Active Flag Set To TRUE By Default bool fullscreen=TRUE; // Fullscreen Flag Set To Fullscreen Mode By Default bool lp; // L Pressed? bool fp; // F Pressed? bool sp; // Spacebar Pressed?

This may be incorrect, but try changing the 4th item in the lightpos array to 0.0f, this will make it a directional light rather than an omniLight
