grow_belly command in the dialogue. i cant seem to figure how to make that one work. i only see one for grow breast. am i messing something?
is it not [GROW_BELLY_BY_<value>] ?
Breast sizes are included in the base game, so it's simple enough to add a dialogue-related trigger for them. And DrZombi has already
done so. The same applies to body-size changes.
However it's important to note that these effects are equivalent to
player action: they directly manipulate the sliders of the in-game menu.
@sby's breastExpansion mod is different, because it uses several simulated factors (such as stomach capacity and digestion) to "decide" on the appropriate size of the girl's body parts. And these sizes will tend to change constantly during gameplay, even when no dialogue is taking place.
It sounds like you're asking for a version of the breastExpansion mod which would respond to the dialogue writer's choices -- rather than being driven entirely by the player's actions (such as "spit or swallow"). If so then that's fine; it's possible to imagine dialogue triggers such as [ADD_CUM_IN_STOMACH_45] or [RESET_GROWTH_TO_ZERO]. But you'll need to
ask sby to include such features in his mod.
