So my step based engine thing...Think blobber-like or rogue-like

I want to have some kind of visibility thing, maybe 5 to 10 units out from the player.

I haven't tried anything yet, but my first idea was to place another block on top of all the "floor" tiles and have a cylinder object that follow/surrounds the player object , and deletes the added floor objects as collisions occur. I can already see some problems with this idea....so....

Any better technique than what I have thought of?

Of course, after you visited an area, that area is always visible to the player, but I don't think the built in "Fog" command will work that way.

It won't no.

You might try something like layered vertical plains, with decreasing alpha transparency (most transparent up front to most opaque at back) and a dark foggy/cloudy texture. Position these at your tile edges to line the unexplored area. You could even animate these with scroll object texture

Yes. Sounds like my block idea. I'll give it a go in the near future. Thanks.

That's how I started to do it in my RTS. It's not the nicest effect of FOW, but I've never come across a really good method for this in DBP.
