gas_mixture

Procs
add	Simpler version of merge(), adjusts gas amounts directly and doesn't account for temperature or group_multiplier.
adjustGas	Takes a gas string and the amount of moles to adjust by. Calls updateValues() if update isn't 0.
adjustGasWithTemp	Same as adjustGas(), but takes a temperature which is mixed in with the gas.
adjustMultipleGases	Variadic version of adjustGas(). Takes any number of gas and mole pairs and applies them.
adjustMultipleGasesWithTemp	Variadic version of adjustGasWithTemp(). Takes any number of gas, mole and temperature associations and applies them.
adjustThermalEnergy	Adds or removes thermal energy. Returns the actual thermal energy change, as in the case of removing energy we can't go below TCMB.
checkTileGraphic	If check_vacuum is TRUE, if one of the mixtures is a vacuum, return FALSE until both are or neither are. Rechecks the gas_mixture and adjusts the graphic list if needed. ///Two lists can be passed by reference if you need know specifically which graphics were added and removed.
compare	Checks if we are within acceptable range of another gas_mixture to suspend processing or merge.
copy	Returns a gas_mixture datum with identical contents.
copyFrom	Copies gas and temperature from another gas_mixture.
divide	Divide all gas amounts by a factor.
equalize	Used to equalize the mixture between two zones before sleeping an edge.
getBreathPartialPressure	Takes the amount of the gas you want to PP as an argument So I don't have to do some hacky switches/defines/magic strings eg: Plas_PP = get_partial_pressure(gas_mixture.plasma) O2_PP = get_partial_pressure(gas_mixture.oxygen) getBreathPartialPressure(gas_pp) --> gas_pp/get_moles()breath_pp = pp getTrueBreathPressure(pp) --> gas_pp = pp/breath_ppget_moles()
getByFlag	Returns the amount of gas that has the given flag, in moles..
getGroupGas	Returns the volume of a specific gas within the entire zone.
getGroupMoles	Returns the volume of the entire zone's gas contents.
getHeatCapacity	Returns the heat capacity of the gas mix based on the specific heat of the gases.
getThermalEnergyChange	Returns the thermal energy change required to get to a new temperature
getTileOverlay	Inlined getTileOverlay(g) End inline
getTrueBreathPressure	inverse
get_volume	LINDA COMPATABILITY PROCS
hasGas	Returns TRUE if the given gas has a volume equal to or greater than the given amount in one group share of gas.
isEqual	Compares the contents of two mixtures to see if they are identical.
merge	Merges all the gas from another mixture into this one. Respects group_multipliers and adjusts temperature correctly. Does not modify giver in any way.
multiply	Multiply all gas amounts by a factor.
remove	Removes moles from the gas mixture and returns a gas_mixture containing the removed air.
removeByFlag	Removes moles from the gas mixture, limited by a given flag. Returns a gax_mixture containing the removed air.
removeRatio	Removes a ratio of gas from the mixture and returns a gas_mixture containing the removed air.
removeVolume	Removes a volume of gas from the mixture and returns a gas_mixture containing the removed air with the given volume.
returnPressure	Returns the pressure of the gas mix. Only accurate if there have been no gas modifications since updateValues() has been called.
setGasMoles	Sets the given gas id's mole count to the specified amount.
shareRatio	Shares gas with another gas_mixture based on the amount of connecting tiles and a fixed lookup table.
shareSpace	A wrapper around share_ratio for spacing gas at the same rate as if it were going into a large airless room.
specificGroupEntropy	Returns the ideal gas specific entropy of the whole mix. This is the entropy per mole of /mixed/ gas.
subtract	Simpler version of remove(), adjusts gas amounts directly and doesn't account for group_multiplier.
updateValues	Updates the total_moles count and trims any empty gases. DO NOT USE. USE AIR_UPDATE_VALUES(air)!!!
