I call SaletRoom.exit every time the player exits to another room.
|
|
Unlike @after this gets called after the section is closed.
|

It's a styling difference.

###
|
|
I call SaletRoom.enter every time the player enters this room but before the section is opened.
|
|
Unlike @before this gets called before the current section is opened.
|
|
It's a styling difference.
|
|
|
|
The upstream Undum version does not allow you to redefine @enter function easily but allows custom @exit one.
|
|
It was renamed as @entering to achieve API consistency.
|
|
###
|
|
enter: (character, system, from) =>
|

return true
|
|

|
###
|
|
Salet's Undum version calls Situation.entering every time a situation is entered, and
|
|
passes it three arguments; The character object, the system object,
|
|
and a string referencing the previous situation, or null if there is
|
|
none (ie, for the starting situation).
|
|
|
|
My version of `enter` splits the location description from the effects.
|
|
Also if f == this.name (we're in the same location) the `before` and `after` callbacks are ignored.
