Making Light2D effects invisible if behind wall.

xRegnarokx

So, just started messing around with Light2D, seems like it could use some work in 4.0. However, what I am wondering is if there is a way to make PointLight2D not seen by player when they are behind a barrier. I have dungeon maps, and I don't want the lights revealing the room Before the player can see the room.

xRegnarokx LightOccluder2D or analogous functionality built into tilemaps.

xRegnarokx Well then disable the light unless there's an unobstructed line of sight between it and the player.

xyz That is what I was thinking would be the solution. I just didn't know if there was a better way to do it. Thanks, I'll just stick with my original thinking.

The only problem is you could walk around a corner and suddenly a light appears that should have illuminated some of the path before hand. Mmk, I guess there or restrictions with 2D if you aren't going to create custom code to control things like lighting. I could create maybe a CanvasModulate that covers the light, that isn't part of the light mask the light illumines. I don't know though if when my characters light reveals part if it would also reveal part of the light behind it or not.

xRegnarokx You can mask out everything that is not seen by the player using light occluder nodes.

xyz Yes, though the effect I am trying to duplicate is if you are in a room, you can't see the light emitted from the lamp in another room down the hall. Once you leave the room you can now see the light emitted into the hall, but you still can't see the room or the source of the light. If I just position light2D they will reveal their areas unless I somehow obscure them until the player would be able to see the effects of these lights.

xRegnarokx Your description sounds contradictory. Can you make an animated mockup?
