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...
