- DESCRIPTION
- Hi everyone, I hope this script helps you for your Virtual World Presentations!
- To use, simply place this script into an Opensim Primitive Object, along with your textures.
- Once clicked, you will get a menu that allows you to:
- RESET - resets the scripts
- Set Timer - Set a timer (in seconds) and start the timer to automatically advance the slides
- Start Timer - Start the timer if it is stopped
- Stop Timer - Stop the timer if it is currently started
- Next - advance to next slide
- Previous - go to previous slide
- lock/unlock - lock/unlock the presenter so only the owner can use
- Messages on / Messags off - turn messages on or off to give textual feedback to all users when moving to a new slide etc
- /
