User:Dora Gustafson/JSON structure facial expression
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
