Crossed() is a byond builtin which is called automatically when two movable atoms overlap (as a side effect of Move(), but not when loc or x/y/z is changed). Previously, turf/Entered() iterated through all objects in the turf in order to tell them an object had entered; with this change, HasEntered() becomes redundant and can be eliminated.
This may reduce lag when a large number of objects are moving in a small space (singularity, mining conveyors, etc) but should cause no changes to functionality at all.
* Replaced "fire" with SPAWN_HEAT. You will have to use it in conjunction with SPAWN_TOXINS to spawn fire.
* Added flags for HEAT, COLD, TOXINS, OXYGEN, CO2, NITROGEN, N2O, FUEL and AIR.
Adds anomalies, special effects which tie into the event system.
Ports bholes into an anomaly, cleans up their code.
Adds new gravitational anomalies. Imagine a trampoline.
Flux event is now an anomaly.
Adds a new pyro anomaly.
Makes trail_holder a child of cleanables instead of blood (this is to
allow add_blood turf proc to spawn blood splatter on blood trails, also
other kinds of blood effects), also cleaned up the blood code a bit.
Big props to Aranclanos, Cheridan, Pewtershmitz and all other coders on
#coderbus for making this happen.
--DO NOT MERGE STILL WIP--
Makes blood trails use overlays, the overlays are contained in a holder
object. DNA is now properly added to them.
todo: redo light, xeno light and xeno heavy trails. help of spriters is
welcome.
The blood trails now follow the path the body has taken and players can
very easily make out said path.
Heavily damaged corpses will have a much thicker blood trail than
corpses with some brute damage. At the moment, trails overwrite
eachother and a placeholder icon set is used for alien heavy blood
trails.
Changed atom's bullet_act to call the projectile's on_hit, and changed
most bullet_acts to call on_hit as well. Removed some now-unnecessary
snowflake code.
These changes will make projectiles which should effect non-mobs, such
as the gyrojet and the ion rifle, work properly. Inanimate objects can
now be empulsed with the ion rifle, whose projectiles used to dissipate
on hitting anything but a mob. Gyrojets now explode on most objects, as
opposed to just on walls and mobs, and the snowflake code that made them
work on walls is no longer necessary. The code for pulse rifles'
breaking walls has been moved from a check in turf to a check in pulse
beams, and has been expanded to include structures, allowing them to
(slowly) break girders. For coders, it means that on_hit is a reliable
proc for the effect of a bullet's hitting an object.
