Refactored encounters schema so HG/SS can work.
Conditions are now condition values; condition groups are conditions. Types are now terrain. Slots are first-class things. Encounters' condition values and slots' conditions have been broken off into their own tables, as HG/SS has several slots affected by multiple conditions.

Within a given area in a given game, encounters are differentiated by the
|
||||
slot they are in and a world condition.
|
||||
"slot" they are in and the state of the game world.
|
||||
|
||||
Groups of slots belong to encounter types; these are what the player is
|
||||
doing to get an encounter, such as surfing or walking through tall grass.
|
||||
What the player is doing to get an encounter, such as surfing or walking
|
||||
through tall grass, is called terrain. Each terrain has its own set of
|
||||
encounter slots.
|
||||
|
||||
Within an encounter type, slots are defined primarily by rarity. Each slot
|
||||
can also be affected by a world condition; for example, the 20% slot for
|
||||
walking in tall grass is affected by whether a swarm is in effect in the
|
||||
areas. "There is a swarm" and "there is not a swarm" are conditions, and
|
||||
together they make a condition group. However, since "not a swarm" is a
|
||||
base state rather than any sort of new state, it is omitted and instead
|
||||
referred to by a NULL.
|
||||
Within a terrain, slots are defined primarily by rarity. Each slot can
|
||||
also be affected by world conditions; for example, the 20% slot for walking
|
||||
in tall grass is affected by whether a swarm is in effect in that area.
|
||||
"Is there a swarm?" is a condition; "there is a swarm" and "there is not a
|
||||
swarm" are the possible values of this condition.
|
||||
|
||||
A slot (20% walking in grass) and single world condition (NULL, i.e. no
|
||||
A slot (20% walking in grass) and any appropriate world conditions (no
|
||||
swarm) are thus enough to define a specific encounter.
|
||||
|
||||
Well, okay, almost: each slot actually appears twice.
