Update 3/24/17
Added 2017-03-24 22:15:09 +0000 UTCI've decided to do updates whenever I make significant progress. For a while they may be daily, but who knows.
After getting a lot of background code done for things like the auto healing, damage causing, and general spanking event processes, I ended up with a system involving 12 different states possible that indicate butt damage. These states are reachable in a 100 point system which starts at 0 and ends at 100. While I could have just had a 10 point system with the same results, 100 points means there can be minute changes of healing or damaging done without changing your state over time. I also made a system that automatically updates a value based on your underwear and doesn't require any custom changes to the actual spanking scenes for damage diluting. It also just gives a value based on the protection of the underwear. So it will now be possible to add many different types of underwear as long as they don't require any special treatment (like different colors of panties, having a thong being considered bare, etc.). Also added behavior and dominance stats. Both start at 50/100, while behavior will lower for naughty actions and rise for noble actions, and will change dialogue for characters if it rises or falls enough. Dominance works in a similar way, while rising for tough or commanding actions, and falling for weak and submissive actions. This stat however doesn't affect npcs in the same way. Instead, major npc's will have their own dominance stat which is based on their interactions with the player. The stat will start at different values if the npc is naturally sub or dom. The players Dom stat modifies the npc's initial impressions the character has of the player. Lastly, I've been working on a system I call "Familiarity" with npcs. Aside from their dom stat, npc's will also have their own personal familiarity stat which is based around how well they know the player. Some characters won't be interested in spanking talk or other things unless their familiarity with you is at a certain point. I'm having thoughts about adding a sort of gifting mechanic for the more important npc's, so you can give certain items to increase relation points, but since these last few are only in the planning stage I'll be thinking about adjustments along the way.
Currently, I've just had a eureka moment and have been working on the much anticipated spanking visual/gui. It's going to involve a lot of pictures being set up, and a lot of work.
This was over the course of a few days, so don't expect updates of this size every day.
