1. Introduction

Master Studio Behavior Arrange (BA) files are text based -- you can open them in Notepad.   Each line starts with a character or word indicating what follows.   All parameters are separated by colon ( : ) characters.

Behaviors are organized into frames or pages.   A single behavior file can have dozens or hundreds of frames.   Behavior Arranger shows each frame on its own editor page.   Group boxes are used to reference frames within another, creating a hierarchy of sorts.   Frames always have a single entry point, but can have multiple exit points (or none at all).

A Action Block.  Contains lists of commands for AIBO to perform.  It's parameters are as follows:
  1. Block Number
  2. Block Name (quoted)
  3. Block horizontal workspace coordinate in grid units
  4. Block vertical workspace coordinate in grid units
  5. Block horizontal size in grid units

  10. Optional.  Path to background bitmap file (quoted)
Zero or more optional lines of R-Code commands can follow, which start with ">" continuation characters.   The R-Code commands are composed of:
  • Two colon seperated keywords (the second if which can be blank)
  • Five operands (variables, numbers, etc...).  Unused operands are blank.
  • A field that's always 0
  • Comment
Example:
A40003:"STAND":200:110:100:60:40002,99999999,99999999,99999999:0:
>PLAY:ACTION:STAND:::::0:

  • Variable
  • Operator (=, <>, >, >=, <. <=, or Bit)
  • Variable or Number
  • Name of connected block
  • Two blank fields

Zero or more optional lines of return statements follow, which start with ">" continuation characters.   The branch statements are composed of:
  • Name of exit terminal (from called frame)
  • Three blank fields.

>Head_OFF:::::::10002,99999999,60,99999999:
> Continuation line.   Used by Action, Branch & Group blocks (see above).
//
 Program comments.
[ Platform model & language.  ie: [ERS-210(E)]  (AMS 1.1 only)

Any line not starting with one of the above is ignored.


3.  Connections

Connections between blocks are tracked by block numbers  -- the value immediately following a start-of-line character.   For example, the connection below means jump to block number 10001.
10001,99999999,99999999,99999999
The three comma seperated values following the block number are Behavior Arranger guide information for drawing connection lines.   All 9's means use the default routing.   Click-n-drag a connection line, and these values get initialized.

The three values are:
  • Vertical distance from bottom of starting block (in grid units), for a horizontal line.
  • Horizontal distance from center of starting block (in grid units), for a vertical line.
  • Vertical distance from top of ending block (in grid units), for a second horizontal line.
For example, the image (to right) shows the connection:  "10002,20,80,-40"
