Hi scitydreamer,
That sounds like a nice suggestion! I initially designed the fog of war to automatically reveal what the player sees based on the default top view. I can add a Plugin Parameter to let the dev decide whether to reveal based on top view or fixed number of tiles.
In the meantime, you can create a new plugin, give it any name, put it below Minimap, and write:
var MK = MK || { }; // Override MK.Minimap.fogOfWar.isSeen = function(x, y) { return MK.Minimap.fogOfWar.distance($gamePlayer.x, $gamePlayer.y, x, y) <= 3; }
Replace the number 3 with your desired range. Euclidian distance is used, so 3 may not be exactly "3 tiles", so you want to play around a bit.
