Is there a way to illuminate the floor/tiles in a 2d platformer?

Hi all,

I have a small issue, I'm wondering if it's at all possible to light up the floor underneath the player character?

At the moment I have a very simple circle gradient which is on the layer behind the player and tiles. This is fine and looks nice enough, but I'd prefer to light up *only* the floor, if that's possible?
I was looking around for any shaders that could potentially ignore one layer and appear on objects on a different layer, for example, but I'm not sure something like that exists.

I've cheesed it in the video clip to show what I mean, although you can obviously see the problem with doing it that way:pacman:

Yeah I suppose something like that could work, and maybe having a proximity sensor to adjust the semi transparency. At the moment I've gone with this, not sure how viable it'll be in the long run, but I've placed the bottom part of the floor on a different layer so it overlaps the light: Please login to see this attachment.

Ah I do have a subtract layer, dark grey object for the screen and an object with a hole to create that flashlight effect already but like you said, it creates holes rather than lights.

The add effect is what I've used in that screenshot, but with a slight blend coefficient. I do kind of like having a bit of light behind the player too.

I would use an object that only covers the floor but I'm not sure how to go about doing it because, the tiles vary alot in shape and angle, so I think eventually it would "clip" somewhere and break the illusion. Hence why Ive just blocked it completely by using the layer on top.
