http://forums.nanotrasen.com/viewtopic.php?f=16&t=12096 > UpdateAffectingLights() is a bit less silly. It now uses oview() to find lights which could be shining on it. It only searches a maximum of LIGHTING_MAX_LUMINOSITY_STATIC-1 away from itself, as this is all it needs to do (reducing the number of atoms it searches/lights it updates). > UpdateAffectingLights() is called more sensibly, generally it will only be called when opacity actually changes on a lit turf (or something in a lit turf), as opposed to before where it would be called simply if something was opaque. > Fixes a typo in cheap_hypotenuse(), it will now work correctly. > Added circular lighting (using cheap_hypotenuse, a cheap linear approximation of pythagoras theorem). Old square lighting is toggable by commenting out #define LIGHTING_CIRCULAR > Wall-fixed lighting will break when Move()ed. This means their lighting will not be updating whilst the singulo is on a rampage (which would cause lots of lighting updates). This should help reduce lighting updates a fair bit in such circumstances. Also the lord of darkness actually creates darkness! omg >Halved the theoretical number of calls to UpdateAffectingLights() by turfs being deleted/created (aka replaced), by moving relevant code from New/Del into ChangeTurf(). Tidied ChangeTurf up a little. >SpaceVines now update opacity correctly (this somewhat worries me though) >Reduced the range of dynamic lighting effects for most objects. Fixed the bug where mob luminosity could try to go negative when dropping many held active flashlights. >Space area no longer uses dynamic lighting. (at request) >Fewer shades of darkness (reduced from 7 to 6) - means fewer shift_to_subarea calls and makes lower luminosity lights appear brighter >Turfs can be luminous, removed the warnings. capped luminosity effects of turfs to a radius of 1. >PDAS ARE NO LONGER SUNS! >ChangeTurf() no longer replaces turfs with turfs of the same type. This means that singulos will no longer replace space with space with space over and over and over every tick >there is a cpu-usage cap thingy on the lighting process(). It's currently set to (a ridiculously high) 98. This simply stops the process attempting to do any more work when the server is already dying. If you're feeling brave you could probably reduce further. git-svn-id: http://tgstation13.googlecode.com/svn/trunk@5650 316c924e-a436-60f5-8080-3fe189b3f50e
