BS12 object based lighting system from VG, ported to TG by Unusual Crow with plenty of help from PJB.
|
|
*/
|
|
|
|
/*
|
|
Changes from TG DAL:
|
|
- Lighting is done using objects instead of subareas.
|
|
- Animated transitions. (newer TG DAL has this)
|
|
- Full colours with mixing.
|
|
- Support for lights on shuttles.
|
|
|
|
- Code:
|
|
- Instead of one flat luminosity var, light is represented by 3 atom vars:
|
|
- light_range; range in tiles of the light, used for calculating falloff,
|
|
- light_power; multiplier for the brightness of lights,
|
|
- light_color; hex string representing the RGB colour of the light.
|
|
- SetLuminosity() is now set_light() and takes the three variables above.
|
|
- Variables can be left as null to not update them.
|
|
- SetOpacity() is now set_opacity().
|
|
- Areas have luminosity set to 1 permanently, no hard-lighting.
|
|
- Objects inside other objects can have lights and they properly affect the turf. (flashlights)
|
|
- area/master and area/list/related have been eviscerated since subareas aren't needed.

Relevant vars/procs:
|
|
|
|
global: (uh, I placed the only one in lighting_system.dm)
|
|
- var/list/all_lighting_overlays; Just a list of ALL of the lighting overlays.
|
|
|
|
atom: (lighting_atom.dm)
|
|
- var/light_range; range in tiles of the light, used for calculating falloff
|
|
- var/light_power; multiplier for the brightness of lights
|
|
- var/light_color; hex string representing the RGB colour of the light
|
|
|
|
- var/datum/light_source/light; light source datum for this atom, only present if light_range && light_power
|
|
- var/list/light_sources; light sources in contents that are shining through this object, including this object
|
|
|
|
- proc/set_light(l_range, l_power, l_color):
|
|
- Sets light_range/power/color to non-null args and calls update_light()
|
|
- proc/set_opacity(new_opacity):
|
|
- Sets opacity to new_opacity.
|
|
- If opacity has changed, call turf.reconsider_lights() to fix light occlusion
|
|
- proc/update_light():
|
|
- Updates the light var on this atom, deleting or creating as needed and calling .update()
|
|
|
|
|
|
turf: (lighting_turf.dm)
|
|
- var/list/affecting_lights; list of light sources that are shining onto this turf
|
|
- var/list/lighting_overlays; list of lighting overlays in the turf. (only used if higher resolutions
|
|
- var/lighting_overlay; ref to the lighting overlay (only used if resolution is 1)
|
|
|
|
- proc/reconsider_lights():
|
|
- Force all light sources shining onto this turf to update
|
|
|
|
- proc/lighting_clear_overlays():
|
|
- Delete (manual GC) all light overlays on this turf, used when changing turf to space
|
|
- proc/lighting_build_overlays():
|
|
- Create lighting overlays for this turf
|
|
- proc/get_lumcount(var/minlum = 0, var/maxlum = 1)
|
|
- Returns a decimal according to the amount of lums on a turf's overlay (also averages them)
|
|
- With default arguments (based on the fact that 0 = pitch black and 1 = full bright), it will return .5 for a 50% lit tile.
|
|
|
|
atom/movable/lighting_overlay: (lighting_overlay.dm)
|
|
- var/lum_r, var/lum_g, var/lum_b; lumcounts of each colour
|
|
- var/needs_update; set on update_lumcount, checked by lighting process
|
|
|
|
- var/xoffset, var/yoffset; (only present when using sub-tile overlays) fractional offset of this overlay in the tile
|
|
|
|
- proc/update_lumcount(delta_r, delta_g, delta_b):
|
|
- Change the lumcount vars and queue the overlay for update
|
|
- proc/update_overlay()
|
|
- Called by the lighting process to update the color of the overlay
