A Spotlight is a cone-shaped beam of light emitted from a point in one direction, similar to the light produced by a flashlight or stage lighting. Compared to other lights, spotlights have an additional
SpotAngle property, which is used to adjust the light range of the spotlight.
In the editor, one can clearly see the position, color and light range of the light as well as its spot angle, as shown in the following image. With the Transform Gizmos in the upper left corner of the editor, it is possible to adjust the position and direction of the spotlight.
See Adding Lights for how to add spotlights to a scene.
For the Spotlight component interface, please refer to SpotLight API.
