when injured/bleeding, engaged in melee combat, or if you shoot someone at VERY close range, your hands and clothes should be able to get covered in blood. having bloody clothes would make them get ruined/lose durability faster, but slightly reduce zombie aggro when walking around normally (they think you're one of them). stealth aggro would remain unchanged. they would also make you ever so slightly colder
a similar state would be dirty clothes. this would by a noticeable margin reduce aggro distance for all NPCs(zombies, animals, etc), but would increase durability loss somewhat faster than bloody clothing. you would get dirty clothes by moving around while prone, and especially fast while crawling near bodies of water (because mud). getting cut/injured with dirty clothes on would have a higher risk of getting an infection
both effects could be stackable, and would have a visual overlay on your clothes to accompany them. clothes would instantly get cleaned off if they get drenched/soaked (if you get in a body of water), but at a slight durability cost. to avoid losing more durability you would have to take the clothes off and use a "wash" action near water
if you have are missing an article of clothing and an action occurs which would usually trigger that article of clothing becoming dirty or bloody, your body will instead receive that effect and overlay (if you eviscerate an infected with a double barrel without a shirt on, for example, your torso would get covered in blood, or if you're naked and crawl around in some dirt near a body of water, you'd see you'd be covered in dirt). if you put on the article of clothing after getting the place where it would be worn dirty/bloody, that effect would slowly begin to transfer over to the clothing too. you would be able to clean/wash yourself near water or with a container of water. having blood on your body would have no negative effects other than clothing transfer, but having dirt on your body would double the chance of getting an infected wound, if injured there by any means at all (could be cutting your feet, getting shot, etc etc)
for player control it'd be nice if you could combine a blood bag with any article of clothing to be able to cover it in blood, if you intentionally wanna sacrifice durability to look like a badass, or to make yourself look injured when you really aren't (lotsa possibilities with this)
server owners should also be able to toggle the negative effects of being bloody/dirty to keep them solely cosmetic if they want to
would be cool overall and also adds a neat bit of realism. im getting hyped just imagining pummeling a guy with 12 gauge, and when coming up to his body, you'd see his clothing is ruined & covered in blood, or after beating a guy to death with a hammer and then seeing your hands and clothing covered in blood, along with his. adds more feedback to damage, and also just makes you look awesome. or scary. or both. imagine how terrifying cannibals would look like chasing you after cutting up a body, covered head-to-toe in viscera? hell yeah man
preferrably the blood overlays wouldn't be too exaggerated. more like just streaks, slight misty splatters, and several large soak/stain effects that only appear on bloody clothing and not on the body. better yet would be to randomize the rotation and size for these effects every time they're applied so it doesnt look too uniform.
this is a small detail but it'd be cool if, when headshotting a person with a helmet on, helmets could have the blood effect applied to them aswell (with no downsides though, just cosmetic. and you'd still be able to wash it off with water
