The Functional Spec explains how a user interacts with a feature, and what results they can expect from the feature. Ideally, the UI will indicate what the user can expect to happen next. Use screenshots when appropriate.

General Description

What does this feature do? Allows the user to store items.

Interface Requirements

How does the user use/activate this feature? Clicking the Inventory button or hitting ctrl-i.

Performance Requirements

Will this feature affect:

  • Client FPS? YES. Large inventories take longer to draw. (perhaps this is fixed)
  • Simulator FPS? YES. Inventory is fetched from dataserver on the Simulator, so it may have a small effect on Simulator performance.
  • Database? YES. The dataserver fetches inventor from the Database.
  • Asset server? YES. Rezzing items reads from the Asset server. Creating invetory items writes to the Asset server.
  • Network load? YES. The inventory structure must be streamed to you. Rezzed or opened items must be streamed to you. Uploaded items must be streamed to the asset server.
  • Any other system? NO.

Design Constraints

  • Will this feature be unavailable on certain hardware? NO
  • Is this feature consistent (similar look & feel) with other features? PARTIAL. Inventory has it's own Menu which is not accessible from the keyboard.
  • Is this feature well integrated (accessible when you need it, and in the place(s) you expect to find it)? YES
  • Is this feature discoverable (newbie friendly)? PARTIAL. There's room for improvement.
  • Is this feature Safe, Predictable, and Responsive? YES.

Feature Dependencies

  • Features that this feature will affect

Attachments, Rezzing objects

  • Features that affect this feature

Upload Assets, Focus, Take, Take Copy


Security risks

  • Does this feature give access to something it should not?

NO

Feature Rules

The rules of the feature, organized in order of precedence. (eg. Rule 1 supersedes Rule 2, which supersedes Rule 3)

Object taken or returned into inventory go into their previous folder. Returned object that have no previous folder will be put in the Lost and Found folder.


Accepted or uploaded assets of a certain type (eg. Clothing, Script, Animation) will go into a system folder of the same type. Accepted categories will go into the Inventory folder.

Feature Usage

When appropriate, the feature will be laid out in chronological order, or in the order they are most likely to be used. (eg. Create a group, then add members, then deed land, ... kick members, leave group)
