I have been adding edge shadow options on a layer by layer basis to Dungeon Demon this week (as inspired by comments in this thread: http://forums.indiegamer.com/showthread.php?t=22369). Here are some first results, I'll be posting some continent maps as soon as I get a little more code working. I have given the designer control over interior and (soon) exterior edge shadows/glow effects. Here's a sample dungeon built with a floor layer and then a wall layer on top that has some alpha channel to create a drop shadow effect. Here is a before screenshot: and after a slightly green tinted shadow (I'm a programmer, color choice may not be optimal) has been been added with the new edge effects option to the floor layer: Any constructive feedback would be appreciated as I'm in the thick of the code right now. Thanks.
