light

The standard light tube fixture

Vars
brightness_range	Light range (Also used in power calculation)
bulb_emergency_colour	The colour of the light while it's in emergency mode
deconstruct_type	What light construct type to turn into when we are deconstructed
extinguished	Was this light extinguished with an antag ability? Used to ovveride flicker events
fitting	Type of light bulb that goes into the fixture
flickering	Is the light currently flickering?
light_type	Item type of the light bulb
lightmaterials	Materials the light is made of
nightshift_allowed	Allowed to be switched to night shift mode?
nightshift_enabled	Currently in night shift mode?
nightshift_light_color	The colour of the light while it's in night shift mode
nightshift_light_range	Light range when in night shift mode
on	Is the light on or off?
rigged	Is the light rigged to explode?
status	Light fixture status (LIGHT_OK \| LIGHT_EMPTY \| LIGHT_BURNED \| LIGHT_BROKEN)
switchcount	How many times has the light been switched on/off? (This is used to calc the probability the light burns out)
turning_on	Is the light currently turning on?
Procs
_turn_on	The actual proc to turn on the lightbulb.
flicker_event	Flicker routine for the light. Called by invoke_async so the parent proc can return immediately.
update	Updates the light's 'on' state and power consumption based on /obj/machinery/light/var/on.

Proc Details

proc
_turn_on
(trigger, play_sound)

The actual proc to turn on the lightbulb.

Private proc, do not call directly. Use /obj/machinery/light/proc/update instead.

Sets the light power, range, and colour based on environmental conditions such as night shift and fire alarms. Also handles light bulbs burning out and exploding if trigger is TRUE.

proc
flicker_event
(amount)

Flicker routine for the light. Called by invoke_async so the parent proc can return immediately.

proc
update
(trigger, instant, play_sound)

Updates the light's 'on' state and power consumption based on /obj/machinery/light/var/on.

Arguments:

trigger - Should this update check if the light will explode/burn out.
instant - Will the lightbulb turn on instantly, or after a short delay.
play_sound - Will the lightbulb play a sound when it's turned on.
