machinery

Machines in the world, such as computers, pipes, and airlocks.

Overview: Used to create objects that need a per step proc call. Default definition of 'Initialize()' stores a reference to src machine in global 'machines list'. Default definition of 'Destroy' removes reference to src machine in global 'machines list'.

Class Variables: use_power (num) current state of auto power use. Possible Values: NO_POWER_USE -- no auto power use IDLE_POWER_USE -- machine is using power at its idle power level ACTIVE_POWER_USE -- machine is using power at its active power level

active_power_usage (num) Value for the amount of power to use when in active power mode

idle_power_usage (num) Value for the amount of power to use when in idle power mode

power_channel (num) What channel to draw from when drawing power for power mode Possible Values: AREA_USAGE_EQUIP:1 -- Equipment Channel AREA_USAGE_LIGHT:2 -- Lighting Channel AREA_USAGE_ENVIRON:3 -- Environment Channel

component_parts (list) A list of component parts of machine used by frame based machines.

stat (bitflag) Machine status bit flags. Possible bit flags: BROKEN -- Machine is broken NOPOWER -- No power is being supplied to machine. MAINT -- machine is currently under going maintenance. EMPED -- temporary broken by EMP pulse

Class Procs: Initialize()

Destroy()

update_mode_power_usage()
	updates the static_power_usage var of this machine and makes its static power usage from its area accurate.
	called after the idle or active power usage has been changed.

update_power_channel()
	updates the static_power_usage var of this machine and makes its static power usage from its area accurate.
	called after the power_channel var has been changed or called to change the var itself.

unset_static_power()
	completely removes the current static power usage of this machine from its area.
	used in the other power updating procs to then readd the correct power usage.


 Default definition uses 'use_power', 'power_channel', 'active_power_usage',
 'idle_power_usage', 'powered()', and 'use_power()' implement behavior.

powered(chan = -1) 'modules/power/power.dm' Checks to see if area that contains the object has power available for power channel given in 'chan'. -1 defaults to power_channel

use_power(amount, chan=-1) 'modules/power/power.dm' Deducts 'amount' from the power channel 'chan' of the area that contains the object.

power_change() 'modules/power/power.dm' Called by the area that contains the object when ever that area under goes a power state change (area runs out of power, or area channel is turned off).

RefreshParts() 'game/machinery/machine.dm' Called to refresh the variables in the machine that are contributed to by parts contained in the component_parts list. (example: glass and material amounts for the autolathe)

 Default definition does nothing.

process() 'game/machinery/machine.dm' Called by the 'machinery subsystem' once per machinery tick for each machine that is listed in its 'machines' list.

process_atmos() Called by the 'air subsystem' once per atmos tick for each machine that is listed in its 'atmos_machines' list. Compiled by Aygar

proc
use_power_from_net
(amount, take_any)

Attempts to draw power directly from the APC's Powernet rather than the APC's battery. For high-draw machines, like the cell charger

Checks the surplus power on the APC's powernet, and compares to the requested amount. If the requested amount is available, this proc will add the amount to the APC's usage and return that amount. Otherwise, this proc will return FALSE. If the take_any var arg is set to true, this proc will use and return any surplus that is under the requested amount, assuming that the surplus is above zero. Args:

amount, the amount of power requested from the Powernet. In standard loosely-defined SS13 power units.
take_any, a bool of whether any amount of power is acceptable, instead of all or nothing. Defaults to FALSE
