Airstrikes...why did I not yet use that to smash enemies?
Only thing I did was dig out the ground below certain big towers and making them collapse... !
By the way - engraving floors and wall:
I always found it a bit sad that I couldn't engrave constructed floors or walls, since it said "Can only do it on hard materials".
So I went and looked up why that message comes even though I was trying to work on a stone (block) floor, and it seems like it only sees it as a "CONSTRUCTION", not what material that construction is made of. So I added "df.tiletype_material.CONSTRUCTION" to the set against which the tile material is checked. (function IsHardMaterial, line #391)
Constructed floors and walls should now be engravable. It has downsides though, as you can engrave all constructed floors or walls, even those made of "non-hard" material, like wood, the floor/wall will not show as (for example) "*Detailed* granite floor" instead still showing as "Granite Block floor", and when masterfully engraving a constructed floor tile it says "Engraved on the wall[...]" ... so, heh, it's not really working I'd say, maybe even the construction of the wall/floor itself is not working correctly. Overall I just wanted to make all floor tiles look the same ... and get rid of all the damn moss that grew while I hadn't build the roof over my new vulcano workplace (bogeyman kept spawning, trying to kill me while I was working...).
