Recently Goldie and I have been working pretty solidly on further filling out the Body system now that its underlying systems are in place, adding all the remaining parts and describing them via their various interfaces.
This includes lots of lengthy discussions about how we want certain things to behave. Given the nature of each part, most if not all require unique rules and attributes written for them. Testicles, for instance, are quite complex but not the most complicated bodypart. For now I’ve decided we only ever want one scrotum, but it can house any amount of testicles up to 20 pairs. Now, we know we want different types of cum, so the Fluid Type has to be attached to the penis rather than each testicle pair, to avoid indescribable situations with the character ejaculating something resembling Colgate toothpaste.
