Hypothermia And Human Heat Transfer

SUMMARY:

HEAT TRANSFER:

removes useless variables heat_protection & cold_protection as these were in 99% of circumstances the exact same as body_parts_covered
added a new variable, heat_conductivity to all items, determining how fast they conduct heat away from you
added new procs to humans, sweat() & burn_calories() - Now whenever you use up nutriment, you generate heat, but can also expend nutriment to decrease heat.
refactored how heat transfer away from humans worked ( see above)

added Mild Hypothermia (between 32-35C) - this results in shivering, minor slowdown and messages informing the player that they are cold.
added Moderate hypothermia (between 28-32C) - Shivering stops, slowdown increases, may slur/stutter words, chance of dropping items in hand and collapsing temporarily, as well as a 25% chance of "forgetting how to use machines" like when braindamaged
added severe hypothermia (24-28C), shivering stops, player is unconcious, pulse decreases to 30BPM and has a 25% chance of taking 5 oxygen damage, which decreases over time as you are still breathing.
added profound hypothermia (<24C), pulse stops, player has a 25% chance of taking 5 oxygen damage, does not decrease over time as they are not breathing.

(these are only the ones I can remember, I may have missed something out.)

coldingtons,
cryokinesis,

chemicals which chill people DISCLAIMER: Foam Fire Extinguishers were not changed.

added space blankets to a first aid kit.
you can make an advanced space blanket by applying a bear pelt to one, this looks bitching.
space blankets do not conduct heat away from humans, allowing them to heat up, but it slows them down.

You can now construct a ghetto space suit with a space blanket, a fire coat and some wire.
You can now construct a ghetto space helmet with a space blanket, a gas mask, some wire, & a fire helmet.

Stabilises body temperature to 37C.
When a person is dragged in, it will automatically begin stabilising, there is no need for more buttons to be pressed
Takes 5 seconds to heat/cool someone to 37C, which works out as quicker than shaking someone up.
Can be emagged to allow for three extra settings - this process is extremely visible, and there is a different sprite for when an emagged function is used
Can reenable security features to quickly unemag the device
Can bring the device to an emergency stop.
Rare: The person inside turns into soylent green - 50 seconds
Medium: The person inside turns into burned mess - 60 seconds
Well done: The person inside turns into ash. - 70 seconds

Cryo now releases someone at 23C instead of -12C (or 25C if they manually eject)
Manual eject time brought down from 2 minutes to 30 seconds to make it time-neutral
This means that, as the person is ejected below profound hypothermia, they will not breathe until they heat up a wee bit further. This is a positive change, as vox & plasmamen will no longer die from toxin damage/fire immediately after leaving cryo.
People inside a cryo cell do not suffer from hypothermia until leaving.
