Unity has a spotlight object, is there something like this in Phaser?
All I can see in Google is this tutorial - Creating a Flashlight or Spotlight Effect in Phaser 3 @ Playful Game Developmet Blog by Ourcade - but I have no idea how I’d get the light to fade out over distance, or more importantly, how to intersect correctly with walls and doorways in my Tiled map.

that’s awesome exmaple, but my experience does not allow me to change this to such a level that the color is “light” and the shadows are translucent (as in the screenshot in the first post).
