| /datum/bodypart_overlay/dirt_skin | A limb's skin mess: one container image at DIRT_SKIN_LAYER holding the limb's baked image, so a limb adds one overlay
to its person whatever the splats. It lies under the underclothes, the genitals and everything worn. The masks are
its carrier's, clipped to the pixels the limb shows, fading out beside what's worn over them. |
|---|
| /datum/bodypart_overlay/dirt_underclothes | A person's mess on their underclothes: one container image on the chest at DIRT_UNDERCLOTHES_LAYER, over the
underclothes and under the uniform, holding the baked image of each piece worn and shown, already kept to the pixels
it shows. |
|---|
| /proc/dirt_skin_zones | Returns the body zones of the limbs skin mess draws on: the head, the chest and the legs, where aimed mess lands. You
should NEVER modify it. |
|---|
| /proc/dirt_skin_besides | Returns the body zones whose sprites a limb skin mess draws on checks besides its own (ready_skin_masks()): for the
chest the arms, which bring their hands and which no limb skin mess draws on draws (the chest checks the eyes too);
for the rest none. You should NEVER modify it. |
|---|
| /proc/dirt_eye_reads | Returns what a body's eyes and its human head are drawn from as dirt_zone_sources_match() reads them against zone
sources: list(the head, its limb_id, whether it draws eyes, the eyes, their sheet, their state). |
|---|
| /proc/dirt_eyes_unchanged | Returns whether a body's eyes and its human head are drawn from what they were when dirt_eye_reads() read them, read
as it reads them without making a list. |
|---|
| /proc/dirt_mess_baked_image | Returns an image of a surface's baked mess, drawn as it is: its colours and alpha are in its pixels
(dirt_baked_icon()). |
