I have circular sprite near my player which has light white color. I want this sprite to behave as a light so that it affects my other sprite. I want all the sprites near it to light up and other sprites to be dark. If you have any ideas please help. THANKS IN ADVANCE
You can give that sprite a material with an additive blending mode, one of the particle shaders would work as a test. I think that's how Hollow Knight did most(all?) of their lighting. edit. to be clear this will only affect things *under the sprite, not near it.
It was mentioned on here, near the bottom. https://unity.com/madewith/hollow-knight I've tried it myself and it works quite well.
