Builders Buddy v1

Builder's Buddy

This is a repost of the current Builder's Buddy scripts, as originally released on the prior LSL wiki. There are two scripts; One goes in a "base" prim, which is the piece that is moved/rotated/etc. The component script goes into each linked set that makes up the rest of the large build. In short, only one base script, many component scripts. Got it?

Note to Sellers!

Due to a number of people confused by the copyright wording, here's a recap: Use this script any way you want. SELL IT EVEN! Just make sure I am given credit as the creator. That's the only restriction.

//  Script Purpose & Use
//
//  Functions are dependent on the "component script"
//
//  QUICK USE:
//  - Drop this script in the Base.
//  - Drop the "Component" Script in each building part.
//  - Touch  your Base, and choose RECORD
//  - Take all building parts into inventory
//  - Drag building parts from inventory into Base Prim
//  - Touch your base and choose BUILD
//
//  OTHER COMMANDS from the Touch menu
//  - To reposition, move/rotate Base Prim choose POSITION
//  - To lock into position (removes scripts) choose DONE
//  - To delete building pieces: choose CLEAN

//  History
//
// v1.0 - 20060328 - Newfie Pendragon
//      - Original Version
// v1.1 - 20060331 - Kalidor Lazarno
//      - Added a Dialog Engine to the base script
// v1.5 - 20060612 - Androclese Antonelli
//      - Added a random number generator to the dialog engine to elimintate
//        problems with multiple BB boxes cross-talking
//      - Added a timer to the listen command to put it asleep after 10sec.
//      - Added a Menu Description
//      - Added n "creator" flag so the owner could use the same object with full
//        menu options and only a single flag change
//      - Added an "ingroup" flag to enable/disable the same group use function
//      - Non-Admin usage cleans the inventory items as they spawn
// v1.6 - 20060624 - Newfie Pendragon
//      - Added active repositioning (building moves as the base piece moves)
//      - Added "Reset" Option to unlink parts from base temporarily
//      - Modified creator flag to automatically set based if owner is creator
//      - Minor changes to improve code readability (for those learning LSL)
// v1.8 - 20070429 - Newfie Pendragon
//      - Added a variable to allow a user to tweak how long a listener is open,
//        and changed the default to 30 seconds.

///////////////////////////////////////////////////////////////////////////////

// INSTRUCTIONS
//  This is the *Component Piece* half of the Builders' Buddy system.
//  Drop it into each 'piece' of the building.  Drop the Base Prim Script
//  into the prim  that will be the container/box that will be used to
//  store the building once completed.  It can be in each individual
//  prim, but if you link as much as possible (and put the script in the link
//  set), it'll be much more neighbourly and less strain on the sim.
//
// QUICK USE:
//  - Drop this script in the Base.
//  - Drop the "Component" Script in each building part.
//  - Touch  your Base, and choose RECORD
//  - Take all building parts into inventory
//  - Drag building parts from inventory into Base Prim
//  - Touch your base and choose BUILD

// v1.6 - 20060624 - Newfie Pendragon
//      - Added active repositioning (pieces move as the base piece moves)
//      - Pieces use WarpPos technique to instantanetly move large distances
//        - Pieces no longer move until the the "Record" option has been used
//        at least once
//      - Pieces will not move if base is not same owner as the pieces
//      - Pieces no longer 'bounce' when hitting the ground
