It's pretty much what I said.
In my caves. I have a typical 'show picture' that's black with a transparent center to make them lantern effects.
However I'd like it if the image could be set to fade/change opacity as you go in deeper into the cave. So the image starts out at like 120 opacity or less, and as you go deeper it's opacity increases to make it seem the areas growing darker and all you can see is whats visible with your 'light'.
Like this.
You're near the start of the cave, it's a little dark, but you can still see alright.
Now your in a deeper section of the cave, it's darker and all you can see is whats around your light.
I again figured this to be done by sorting out the players X/Y placement to an 'control' event. That the closer you got to said event, the higher the images opacity got thus making things seem to be getting darker. But I can't sort out how to get it to change as you get closer. Plus if you want more then one area to be dark? How would that work?
