These are dark days indeed
I was hoping there was some reaction somewhere (with a flammable mineral being submerged in magma, something..) that resembled an explosion.. I'm assuming if it hasn't already been modded by now then it can't be at all.. which would make Toady's condoning it for modding somewhat difficult, I'd think
Also uranium is at least twice as crazy as what I was thinking, which was: add some saltpeter/sulpher to make generic gunpowder with, use metal pots or barrels as bomb containers ((theoretically stronger explosion based on size of container)), add a cloth wick/fuse soaked in fat or tallow if you wanted to be fancy, toss in some lever-based detonation, call it done)
It'd be hard to code, I suppose, especially if you wanted a realistic shockwave effect that would push things away from the explosion center and damage entities properly (from concussion, shrapnel, potential fire, impact from being propelled into things).. And then one realism calls for another, concerning flammable or explosive materials being exposed to fire or magma (which would probably cause explosions/cave-ins underground upon arrival on new maps)..
Still, I'd have too much fun blasting things if it ever became a reality :| Just pen/pasture the 100 excess cats flooding your fort into a tiny room and then detonate a small bomb on them
Some high-heat non-explosive bombs would be great, too, for areas where you don't want any solid blocks destroyed (in this instance it'd just bake the cats).. Then you could add a 'char' effect that blackened exploded or burned stone surfaces.. Okay, I've got to stop, bahahaha.. Tis good to dream, though.. Toady is apparently a fan of lightning, at least :>
