This recipe will mostly be theories on different lighting types, but we'll also explore a way to easily control the movement of lights.
The four main types of lights that we can use to light up our world are as follows:
Ambient Light: This lights up everything in the scene evenly. It's good for avoiding anything to be in a pitch-black state, but it doesn't create any shadows or nuances. Adding a too bright ambient light will give the world a bland look, while giving it a touch of color can set the mood.
Directional Light: This shines from a particular direction with perfectly parallel rays and without any falloff. This is usually used to simulate a sun, a bright source of light located far away.
Point Light: This shines equally in every direction but with a falloff, meaning this will eventually stop illuminating the surroundings. Usually, this forms most of the light sources in a game scene.
Spot Light: This is exactly as it sounds...
