Interface and code

  • Web based?
  • AJAX?
  • Rails?

Brainstorming

  1. Have defined sections of the page for basic ways to interact with game
    • Room/environment view box
    • Inventory
      • Item view
    • Other characters/NPCs
      • separate from room? or basically like the room is a container and a subwindow that shows what's in the room--items, players, npcs. Things #an go in and out without changing the view of the environment.
    • Combat
    • Conversations
      • Include emotes here? basically, an action window?
      • Split between chat lines/tells/room actions? If we have chat lines/tells
  2. Obvious and non-obvious methods of interaction
    • Obvious methods (go north, wield sword, don armor, press button) as clickable links
    • Non-obvious methods not displayed, but given an empty text box to input commands
  3. Way to script things?
  4. Mobile site?
  5. Telnet option
    • Web interface a wrapper around all information given, but with traditional telnet interface of many lines coming at you?
    • Or telnet interface with a text-based browser style? Keep the different windows?

Database

Fact tables

Every fact table has a non-null primary key (not listed b/c I don't want to have to type "PK" over and over). If a column is a FK link to another table, it will be noted.

Table Columns Notes
Objects wizard_id (FK to wizards), creation date, mass, size_id wizard_id is id of wizard who created object
Sizes size_name, size_order
Room instance area, actions,
General room description columns
Items object_id (FK to objects)
Item personalization item_id (FK to items), character_id (FK to characters), new field name, description
Living creatures size, race_id (FK to races),
Characters
Races size limitations, stat modifiers, racial_adjustment_id (FK to racial adjustments),
Random monster generation parameters
Actions
Guilds
Skills
Areas
Item class
Actions
Spells
Status adjustments
Racial adjustments
Metadata table name, column name, PK_flag, FK_flag, FK_link (FK to metadata_id, self-referential) Can we have this auto-generate? Based on system tables?
Players user_id, object_id (FK to objects), password (encrypted?),
Character sort orders sort column, asc/desc
Wizards character_id (FK to characters), wizard_class_id (FK to Wizard Class), wizarding_start_date
Wizard Class class_name, permissions

Dimension tables

Where X and Y are items in different fact tables.

  • If X will have at most one of Y, then X should have a foreign key to Y's primary key (noted above)
    • If X will always have one Y, then that foreign key should be constrained to not null
  • If X can have many Y, and Y can have many X, then X and Y need a dimension table. Said table should consist of only two items: the primary keys of X and Y
X Y This represents ...
Characters Skills
Characters Guilds
Characters Status adjustments
Characters Racial adjustments
Actions Meta-table item
Items Item class
General room Room instance
Characters Spells
Items Spells
Player


Working tables

Temp tables to be used while player is logged in, dropped after/at reboot

  • Inventory? How to persist, write to more permanent table?
  • Status that wears off


Table brainstorming

  1. Everything as an object
    • Rooms are containers
    • Characters and Monsters/NPCs modeled the same, also containers
    • Object table includes very basic information common to all objects. PK/FK link to other tables
  2. All actions have common ties
    • Actions include spells and attacks, but also skills, emotes, buying, etc.
    • Any interaction with an object, including yourself. Leveling up is an action.
    • Not all actions can be called directly. Some can only be called by computer/other action. This flag can be one of the common ties
    • Actions PK/FK link to other tables to further define them
    • Are actions also items? Or can items have actions? Or can items have access to a class of actions?
  3. Classes of items/actions
    • Clearly defined definitions of items and actions. Adding a new item/action must go into one of these groups. Adding a new class rearranges the DB a bit.
    • Subclasses/Superclasses can be defined to combine/narrow things down. Probably superclasses are more likely, to make things have only one class?

Interaction

  • Modeling NPCs as computer-controlled PCs
  • Objects with built in calls for actions?
  • Characters as special kinds of items?
  • Rooms as special kinds of items?
