Summary0000307: No announcements for blistering/charring, and other fire-related problems
DescriptionIn adventure mode and in the arena I noticed that I never got any warnings at all about heat like I did in the older versions. There was no blistering or charring, just a sudden message telling me that I am melting, followed shortly by me bleeding to death.
Steps To ReproduceGo to adventure mode, and light a tree on fire. then stand next to it for a while.
Additional InformationI'm pretty sure this applies to more then just dwarves but I haven't tested other races yet.

Looking over the raws, I believe this is because the fat has such a low melting point, compared to the rest of the bodies ignite point.

And I do remember seeing "dwarf grease" on the ground at some point when a dwarf came too close to some magma before running away bleeding all over. And grease seems to be what liquid fat is called in the material_template_default.txt file.

I don't see how my bug report involving mudmen is related to this one, other than possibly a temperature related thing.

I think my bug report has more to do with material that its made of.

yea, the melting point for fatty tissue is LOWER then the point for it burning or charring.

Changing those numbers around brings back combat messages I'd thought were lost!

If you lower the ignite point and the heatdam point for skin, fat and muscle to more reasonable levels, as well as raising the melting point for fat, then go fight a fire man or magma man (or a spirit of fire ported forward from 40d), you get exciting messages like "You are blistering! You are burning! You are on fire! You are incinerating!"

I'm wary that doing so may have undone the workaround for the melting rain bug though - the heatdam for living tissue might have been raised as a workaround. But I hope not! Have to embark in a scorching rainforest when I get the chance to test.

Tested by dropping magma in a gigantic panda in arena mode. I controlled it and got messages "You are in fire!You are melting!You are blistering" and in my description got body parts melted and burned. Nothing was modded.
Got the same for a human.
Got a human fighting a magma man, just got messages "You are melting".

To further clarify, the problem seems to be that nearly all of the various "solid" creature materials (including skin, fat, muscle, sinew, and all internal organs) have a COLDDAM_POINT of 9900 (-68°F) and a HEATDAM_POINT of 10250 (282°F).

Realistically, the COLDDAM_POINT of most tissues (especially skin) should probably be closer to 9990 (22°F - really, anything below 32° is dangerous for prolonged periods of time), and a HEATDAM_POINT of 10110 (142°F) would be much more realistic (enough that steam would cause significant damage, just like in real life).
