I've created an esm file for Four-Play: four_play_resources.esm. Like Four-Play itself it's a bit of a work-in-progress. It has keywords and magic effects for various purposes.

Blocking Keywords

These are intended for chastity belts, gags, and other items of apparel that block sexual access to various body parts. Currently we have:

• 4play_blocks_anal
• 4play_blocks_boobs
• 4play_blocks_hands
• 4play_blocks_oral
• 4play_blocks_vag
• 4play_blocks_penile
  

Hopefully the names are self-explanatory. These won't actually do anything until I set up the animation information so that the framework can tell which animations need access to what body parts. Still, the keywords are there and can be used

Locking Devices (Devious and Otherwise)

This tells Four-Play not to remove a particular item of apparel during sex. This currently works and has a demo of sorts; in the test cell, Dr. Li is wearing a Postman's Cap marked with this keyword.

• 4play_do_not_strip
  

Pregnancy

• 4play_creampie
  

This is set by a magic effect that lasts for a short while after vaginal sex.

Cum Effects

Keywords set by magic effects that last for a short time after sex. These are intended to indicate where cum effects should be applied.

• 4play_cum_anal
• 4play_cum_boobs
• 4play_cum_hands
• 4play_cum_oral
• 4play_cum_vag
• 4play_cum_penile
  

Active Sex

These are set by magic effects while a sex act is in progress and should be removed at the end. The body part list may seem familiar.

• 4play_sex_anal
• 4play_sex_boobs
• 4play_sex_hands
• 4play_sex_oral
• 4play_sex_vag
• 4play_sex_penile
  

Sexual Roles

These tell you something about the role an actor has in a sex act. There are flags for rapists and victims, and separately for dominant and submissive roles, which allows consensual BDSM scenes. Additionally there are keywords for solo sex acts and a keyword to flag participants in any sort of sex act in case you just need to find sex regardless of the nature of the act.

• 4play_sex_dom
• 4play_sex_sub
• 4play_sex_rapist
• 4play_sex_victim
• 4play_sex_solo ; next release
• 4play_sex_actor ; next release
  

Factions

Unless anyone major objections, I'm going to deprecate the magic effect/keyword mechanism for sex acts and sexual roles and replace them with factions. It's less work at my end and easier to write conditions for at the users. And possibly more robust too, in light of recent discoveries.

• 4play_sex_anal_fac
• 4play_sex_boobs_fac
• 4play_sex_hands_fac
• 4play_sex_oral_fac
• 4play_sex_vag_fac
• 4play_sex_penile_fac
• 4play_sex_dom_fac
• 4play_sex_sub_fac
• 4play_sex_rapist_fac
• 4play_sex_victim_fac
• 4play_sex_solo_fac
• 4play_sex_actor_fac
  

Blacklisting Actors

Two ways to do this - via a faction or a formlist. Ideally, if you create an NPC that shouldn't engage in sex you would add them to the blacklist faction. If the actor is defined outside of your mod and still needs to be blacklisted, there's a blacklist Formlist as well.

• 4play_blacklist_faction ; actors prohibited from sex acts
• 4play_actor_blacklist ; formlist of banned actors
  

Allowed Races

Races are blocked by default. Anything not explicitly in this list is going to be excluded. Currently only adult ghoul and human races are allowed.

• 4play_allowed_races
