Summary

Hello all. I'm trying to see if anyone can help me realize a small project, and one of the aspects I very much want to implement is gradual discovery of the map tile by tile with a fog of war style thing.   (For quick reference, imagine Etrian Odyssey but playing directly on the minimap. Each step discovers your immediate surroundings). I found the script that would have wonderfully...but for Ace. Here it is in all its glory by Theo Allen: And a video showing it in action:

Hello all. I'm trying to see if anyone can help me realize a small project, and one of the aspects I very much want to implement is gradual discovery of the map tile by tile with a fog of war style thing.

I found the script that would have wonderfully...but for Ace. Here it is in all its glory by Theo Allen:

And a video showing it in action: 














Requirements:


+Must be able to set at least a visibility range of 1 tile in main four directions, but I'd also like to be able to control the visibility range via a simple variable. 


+Must be compatible with variable resolutions (Yanfly Core for resolution)


+Once uncovered it should stay that way (do not carry a circle of light with you, discovered cells stay discovered)


+(Optional) A way to "reset" the cover on a map so it returns to being dark. Not too crazy about this one so if it's fiddly forget it.


In effect each "map" will be a small and snug (think causal mobile games like Dungelot or similar click to discover tile games) where not being able to see whats ahead is exactly the point, or visibility being very limited. 


In theory, each map starts completely dark and you slowly discover it one or two tiles at a time, finding enemies and treasure and so on. A very, VERY loose idea of the kind of stuff I mean when I say small and "minimap" like below. 


Thanks for your time, hope someone can help me with this. I'm willing to trade mapping if you'd like. (And this definitely doesn't have to be custom for me, open use is perfectly fine).
