Intro

So just for the record: I'm a complete LSL n00b. So don't expect much from this page. 'Cause I love the Open Source concept, I'd like to share some of my scripts with other SL Residents =)

Simple Countdown

This script displays a hovering countdown above the item it's placed in.

Basic Notecard-Reader

This script reads notecards placed in the same prim as the script itself.

Teleport via Map

Set the description of the prim this script is attached to, to: SIMNAME/X/Y/Z
The script will read the description and open the map at the defined position in case it is clicked.
Click and hold the prim clicked for more then 4 seconds in order to re-initialize the script.

Buzzer

This script is supposed to be used during meetings so a speaker isn't interrupted by questions while people can still indicate that they would like to speak. Up to 8 people might leave their indication by clicking the item where the script is attached to. Every name will only be listed once.

Click and hold it clicked for more than 3 seconds to delete the upmost name.

Landmark Replacer

The following two scripts are supposed to be used by shop owners who are moving their store to a new spot. Since most owners box their items with a landmark to their shop, all these landmarks need to be updated after the move. Depending on the number of items, this can become an exhausting exercise. It will still remain an exhausting exercise, even with the use of these scripts, but it will at least make it a little faster. The first script zlLandmarkSender is supposed to be placed in a single prim, which contains the landmark to the new store. Alter the LM variable that way, that it's value equals the exact name of the landmark in the objects inventory. Afterwards, rez all your boxes and place the zlLandmarkCleaner&Replacer script inside them. This script will search for exisiting landmarks and remove them. Afterwards, it will ask the previously rezzed prim (server) for the uptated landmark. When you finished placing your scripts in the old boxes, you can click the initially rezzed serverprim and answer the upcoming question with yes in order to remove all zlLandmarkCleaner&Replacer scripts from the boxes and to de-rez the server prim.
