fish_evolution

Fish evolution datums

If present in a fish's evolution_types list, and other conditions are met in check_conditions() then there's a chance the offspring may be of a new type rather than the same as its source or mate (if any).

Vars
conditions_note	A text string shown in the catalog, containing information on conditions specific to this evolution.
new_fish_type	The obj/item/fish path of the new fish
new_traits	A list of traits added to the new fish. These take priority over the parents' traits.
removed_traits	If set, these traits will be removed from the new fish.
required_temperature_max	The maximum required temperature for the evolved fish to spawn
required_temperature_min	The minimum required temperature for the evolved fish to spawn
Procs
check_conditions	The main proc that checks whether this can happen or not. Please do keep in mind a mate may not be present for fish with the self-reproductive trait.
get_evolution_tooltip	Called by the fish analyzer right click function. Returns a text string used as tooltip.
register_fish	Proc called to let evolution register signals that are needed for various conditions.
