I'm not looking for updates... if it still works, I don't think it needs more than that.

Well... the code still works. Although I think Lummox JR has moved on to other things.

Comments from a month ago? Awesome. I was just coming here to make sure this library was current/still functional. :)

One thing I've noticed is that it's faster to save or unload swapmaps if you delete the old swapmap file first:

if (fexists("map_[thisSwapmap.GetSwapmapID()].sav"))
        fdel("map_[thisSwapmap.GetSwapmapID()].sav")  // This is faster than having swapmaps do it.
In tests, it's about four or five times faster, depending on the map size.

I'm thinking the reason for this is probably because Swapmaps is performing some operation on the maps it unloads on if they already exist. If you watch the file while it does that, they deflate slowly before being rebuilt.

(Of course, even a cooler implementation than just flat out deleting the old swapmaps is to back them up first with fcopy() in case your game needs to revert to an earlier version to recover.)

Best library I know of for quickly and effectively managing dynamically generated maps.
