Odor and smelling (This thread stinks!)

[Frank_Stein]

Was thinking about Spaceman senses and realized smell is under utilized. I think smell could add a lot flavor and spice up a few existing jobs and mechanics.

The way I envision smelling working is like this:

---

-Most organic things would emit an odor
-A sniff emote would be created that lets you smell the air when your hands are empty, or what you are holding when you have an item
-Detected smells show up in flavor text, with a description of said smell. Font color and style matching the severity of the smell
-Odors would have three levels of strength

• Weak - Needs special equipment or abilities to detect
  
• Mild - Can only be detected by manually sniffing
  
• Strong - Will be detected automatically
  

-Odors would have 6 levels of reaction

• Strongly negative - Causes severe reaction (Vomiting, stumbling, feinting)
  
• Mildly negative - Causes a unpleasant reaction (Gagging, vision blur, stamina loss rate increase)
  
• Neutral - No effect
  
• Mildly positive - Causes a pleasant reaction (Smile, Stamina regain rate increase)
  
• Strongly positive- Causes a beneficial reaction (Health regeneration, Harmful chem deplete rate increase) 
  
• Mix - Multiple effects (Positive reactions, but negative consequences and vice versa)
  

-Odors would have several degrees of potency that effect the range in which it's detected

•  Small - Effects the immediate tile the object is on
  
• Medium - The smell extends in a 3x3 radius
  
• Large - The smell extends in a 4x4 radius
  
• Lingering - The smell remains on tiles it's effected until it's cleaned or neutralized
  
• Pungent - The smell cannot be overpowered, and will remain detectable even if a stronger smell is present
  

-A weak odor can be overpowered by a mild one, and a mild one by a strong one. You'll almost always only notice the strongest scent
-Crewmen would have a weak, unique smell ID similar to fingerprints. This isn't noticeable to the average person, but a forensic scanner, animal, or someone with a smell enhancing mutation could pick it up.
-Chems would have different scents, similar to their appearance colors. While some would be similar, a suavy person could detect traces of poison in food or drink by sniffing it
-Likewise, some chems could have negative reactions if smelled. Think huffing bleach

So now that mechanics of smell are covered, here's some fun stuff that this could bring

1. A bunch of new items based around creating, detecting, and getting rid of smells
   
2. Security tracking people based on their smell ID
   
3. People masking their smell ID with more powerful smells, like cigarettes or cologne
   
4. Security tracking people based on if they smoke or wear cologne
   
5. Scratch and sniff cards
   
6. People sniffing markers
   
7. Dead bodies leaving a Strong Negative smell, meaning cleaning them up or preserving them would be needed more
   
8. Various forms of "aromatherapy" i.e. people hunting down and creating positive reaction smells
   
9. The Chef's food being a source of good smells
   
10. The Chef's food being a source of bad smells
    
11. People coming out of trash cans with a lingering bad smell, meaning they need to go shower to get rid of it
    
12. Some atmospherics stuff can take advantage of this
    
13. People smelling farts
    
14. People passing out from smelling a particularly bad fart
    
15. Sniffing up lines of coke
