The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.
The script has 19 facial expressions that can be chosen from a menu
- The expressions can also be chosen by random and they can be played in a loop
- The script can be used in a pose ball or in an attached (HUD)prim
- When used for a pose ball the camera position is saved for next session
The script features a JSON structured dialog-menu
- In this case the menu has one main page and three child pages
- The power of JSON shows where the menu is decoded and in the navigation between menus. See the first lines in the listen event handler
