Goblins don't seem to be able to make bronze (bismuth or regular). Is this by design? They probably should be able to imho since they have the ability to smelt iron.
Actually it seems to be any sort of bar involving more than one material. Steel I can understand the removal of.
Also, Goblins can manufacture bolts and crossbows as well as having the marksman skill, but cannot use them.
i perhaps should add in the reactions for bronze. by default, goblins only seem to use copper, silver, or iron.
it seems reasonable that goblins understand the alloying of bronze if they can manage weapons grade iron.
they dont use crossbows? i'll admit i mainly tested that they used bows. have you made sure your crossbow squads are set to use bolts of ammo? are you only using the default "ranged weapon of choice" option, or specifying crossbows? did the goblins in question have hunting, mining, or woodcutting enabled?
i've been working on this only intermittently, i'll have to test for myself later tonight.... my test fortress isnt quite up to producing any kind of weaponry right now, been focusing on cooking and dining ares to test that aspect. i seem to remember them working fine on my last test tower, but that might have been an overflow of bows. looking at the raws, goblins have the use of both crossbows and bows, with the correct ammo, enabled by default.
adding the bronze should be easy - just add this to entity_default in goblins if you dont want to wait for a new upload (i'm accumulating a few changes and fixes first).
[PERMITTED_REACTION:BRONZE_MAKING]
[PERMITTED_REACTION:BRONZE_MAKING2]add this to the main raws, and any already generated worlds. should not require a regen, as adding both jewelcrafting and the ability to make coke did not.
please note, goblins in worlds generated with this setting could come armed with bronze when playing as dwarves. another reason to make your goblin fortress worlds apart from worlds where you play as other races, much like having goblins only active in winter.
