BODYTEMP_AUTORECOVERY_DIVISOR

This is the divisor which handles how much of the temperature difference between the current body temperature and 310.15K (optimal temperature) humans auto-regenerate each tick. The higher the number, the slower the recovery. This is applied each tick, so long as the mob is alive.

BODYTEMP_AUTORECOVERY_MINIMUM

Minimum amount of kelvin moved toward 310K per tick. So long as abs(310.15 - bodytemp) is more than 50.

BODYTEMP_COLD_DAMAGE_LIMIT

The body temperature limit the human body can take before it starts taking damage from cold. This also affects how fast the body normalises it's temperature when cold. 270k is about -3c, that is below freezing and would hurt over time.

BODYTEMP_COLD_DIVISOR

Similar to the BODYTEMP_AUTORECOVERY_DIVISOR, but this is the divisor which is applied at the stage that follows autorecovery. This is the divisor which comes into play when the human's loc temperature is lower than their body temperature. Make it lower to lose bodytemp faster.

BODYTEMP_COOLING_MAX

The maximum number of degrees that your body can cool in 1 tick, due to the environment, when in a cold area.

BODYTEMP_HEATING_MAX

The maximum number of degrees that your body can heat up in 1 tick, due to the environment, when in a hot area.

BODYTEMP_HEAT_DAMAGE_LIMIT

The body temperature limit the human body can take before it starts taking damage from heat. This also affects how fast the body normalises it's temperature when hot. 340k is about 66c, and rather high for a human.

BODYTEMP_HEAT_DIVISOR

Similar to the BODYTEMP_AUTORECOVERY_DIVISOR, but this is the divisor which is applied at the stage that follows autorecovery. This is the divisor which comes into play when the human's loc temperature is higher than their body temperature. Make it lower to gain bodytemp faster.

BODYTEMP_HEAT_WOUND_LIMIT

The body temperature limit the human body can take before it will take wound damage.

BODYTEMP_HULK_COLD_DAMAGE_LIMIT_MODIFIER

The modifier on cold damage limit hulks get ontop of their regular limit

BREATH_PERCENTAGE

Amount of air to take a from a tile

BREATH_VOLUME

• liters in a normal breath. note that breaths are taken once every 4 life ticks, which is 8 seconds
• Addendum for people tweaking this value in the future.
• Because o2 tank release values/human o2 requirements are very strictly set to the same pressure, small errors can cause breakage
• This comes from QUANTIZE being used in /datum/gas_mixture.remove(), forming a slight sawtooth pattern of the added/removed gas, centered on the actual pressure
• Changing BREATH_VOLUME can set us on the lower half of this sawtooth, making humans unable to breath at standard pressure.
• There's no good way I can come up with to hardcode a fix for this. So if you're going to change this variable
• graph the functions that describe how it is used/how it interacts with breath code, and pick something on the upper half of the sawtooth

COLD_SLOWDOWN_FACTOR

Humans are slowed by the difference between bodytemp and BODYTEMP_COLD_DAMAGE_LIMIT divided by this

EXCITED_GROUP_BREAKDOWN_CYCLES

Some further context on breakdown. Unlike dismantle, the breakdown ticker doesn't reset itself when a tile is added This is because we cannot expect maps to have small spaces, so we need to even ourselves out often We do this to avoid equalizing a large space in one tick, with some significant amount of say heat diff This way large areas don't suddenly all become cold at once, it acts more like a wave

Because of this and the behavior of share(), the breakdown cycles value can be tweaked directly to effect how fast we want gas to move number of FULL air controller ticks before an excited group breaks down (averages gas contents across turfs)

EXCITED_GROUP_DISMANTLE_CYCLES

number of FULL air controller ticks before an excited group dismantles and removes its turfs from active

MINIMUM_AIR_TO_SUSPEND

Minimum amount of air that has to move before a group processing can be suspended (Round about 10)

MINIMUM_HEAT_CAPACITY

I feel the need to document what happens here. Basically this is used catch rounding errors, and make gas go away in small portions. People have raised it to higher levels in the past, do not do this. Consider this number a soft limit If you're making gasmixtures that have unexpected behavior related to this value, you're doing something wrong.

On an unrelated note this may cause a bug that creates negative gas, related to round(). When it has a second arg it will round up. So for instance round(0.5, 1) == 1. I've hardcoded a fix for this into share, by forcing the garbage collect. Any other attempts to fix it just killed atmos. I leave this to a greater man then I The minimum heat capacity of a gas
