INTRODUCTION
|
||
This Rooms Users Package provides a number of "touchy" buttons i.e. buttons that visually depend on the state of the world and change the state of the world when touched. Right now I provide three types of touchy buttons: includer, toggler, and once-only. You can make a touchy button by calling rooms::make-<touchy-type>. I will take suggestions for any others that people think may be useful since I'm trying to abstract the touchy technology.

BUTTON CONSTRUCTORS
|
||
(ROOMS::MAKE-INCLUDER ROOM-NAME) [Function]
|
||
Includers allow you to conveniently mixin or mixout rooms. For example, you can have "Notecards-Mixin" and "Programming-Mixin" Rooms and have includer buttons in your personal "Pockets." Then you can include these functionality traits whenever you need them no matter the room.
|
||
|
||
(ROOMS::MAKE-TOGGLER VARIABLE-NAME) [Function]
|
||
Toggle buttons allow you to toggle boolean variables. This should obviously be generalized to something that allows you to select or circulate through value settings.
|
||
|
||
(ROOMS::MAKE-ONCE-ONLY FORM INITIAL-TEXT FINAL-TEXT) [Function]
|
||
A once-only button evaluates a form exactly once in a sysout and then displays that it is exhausted. For Example:
|
||
(ROOMS::MAKE-ONCE-ONLY (IL:PROMPTPRINT "Hello, World") "Fire..." "Exhausted")
