Lag reduced by approx 30% (0.5 seconds of total 1.5 on my system). Some air alarms on the map copypasted from toxins one, with its special settings. Added list of used frequencies and HOW IT WORKS section to communications.dm. Sorry for some engrish. git-svn-id: http://tgstation13.googlecode.com/svn/trunk@895 316c924e-a436-60f5-8080-3fe189b3f50e

Every cycle, the pump uses the air in air_in to try and make air_out the perfect pressure.
|
|
|
|
node1, air1, network1 correspond to input
|
|
node2, air2, network2 correspond to output
|
|
|
|
Thus, the two variables affect pump operation are set in New():
|
|
air1.volume
|
|
This is the volume of gas available to the pump that may be transfered to the output
|
|
air2.volume
|
|
Higher quantities of this cause more air to be perfected later
|
|
but overall network volume is also increased as this increases...
