There is a ready to use script or plugin for spoiling food, unfortunately it also spoils non-perishables... Was planning to look into it later on.
I also know that even though the caste system is no longer implemented, it is readily accessible and I was under the impression that a lot of people use it for various mods. I know for a fact that DFMW does.
So Grimlocke, I was looking into your raws for the buildings for your mod, I was trying to figure out the name of the trip hammer for awhile now and wanted to thank you for giving me that info.
I also wanted to ask the people that I'm going to draw from and are going to help with this right now if its cool if we remove magma from our fuel sources where it wouldn't apply though. Even modern day geothermal magma chambers only reach a temp of 900 Celsius max while others barely make 500. These temperatures are not hot enough for everything and I feel like they are a bit cheaty because it allows for players to give up wood production. following this guide
http://www.blksmth.com/heat_colors.htm the finishing and regular forges could use the geothermal heat for preparing metals for work as well as melting borax and silver, but it wouldn't be enough to smelt with otherwise and it seems like a bad design as the air over magma is not necessarily the correct chemical composition. There is a power module in dfhack that we could use magma for the trip hammer, but I'm kind of just throwing ideas around and was wanting some feedback?
