How to make darkness and light source in 2D Unity game?

Question

Unity

It is necessary to make complete darkness on the stage.
It has a character who will play the role of a lantern (Point Light).
Played with Window > Lighting > Scene, made the character a light source, but nothing works. What am I doing wrong and what should I do?
Unity version: 5.6.4

Answer 1

Window > Lighting > Scene
are ambient settings, realtime lighting generation (shadows and all) and light baking. where did you "make the character a light source"??
take the scene, remove all light sources. in the lighting settings - remove Ambient and other global illumination, if not needed. (read the description in the documentation of who is responsible for what)
add a light source to the character.
don't forget to make the light Realtime and the environment it interacts with - shouldn't be static baked already.
start with a simple empty scene with cubes. no matter 2d or 3d
and do not forget that there are versions in the unit - which are very different, so either indicate yourself or a screenshot of the editor (you can usually see it if you do not cut the window frame)
