lsDialog
lsDialog is an universal notecard driven menu dialog system. lsDialog could be used in a HUD or rezzed objects, providing one prim dialog trees or multi prim button dialogs. You can restrict usage to owner, group, named avatars or everybody. lsDialog is using llSay or llMessageLinked to comunicate with other scripts.

Notecard: .lsDialog
The .lsDialog notecard defines the menu dialog tree. A typical simple notecard could look like:
# default is to ask repeating ... remove comment if #Dialog=Once #Dialog=Link # allow only one of the following #Allow=Owner #Allow=Group #Allow=All # and in addition several named avatars #Allow=Kephra Nurmi #Allow=Alez Ember [*] Reset=link 0 reset [Size] 90%=link 0 *,size,90 95%=link 0 *,size,95 100%=link 0 *,size,100 105%=link 0 *,size,105 110%=link 0 *,size,110 [Color] Lime=link 0 glass,color,Lime Ivory=link 0 glass,color,Ivory Cyan=link 0 glass,color,Cyan
This notecard will define a single prim dialog system with one top menu called 'Reset' and two sub menus called 'Size' and 'Color' with link action on channel 0 and default permissions. The object description defines the name for the top menu dialog. Each menu starts with a section header in brackets followed lines to define the dialog entries. Each entry has a name equal to an action, a channel and a string.
Possible actions are:
- say - llSay(ch,val);
- shout - llShout(ch,val);
- whisper - llWhisper(ch,val);
- region - llRegionSay(ch,val);
- root - llMessageLinked(LINK_ROOT,ch,val,id);
- link - llMessageLinked(LINK_SET,ch,val,id);
- this - llMessageLinked(LINK_THIS,ch,val,id);
The top of the notecard, before any sections in brackets start, defines the permission and behavior. The hash marks lines as comments. Uncommenting Dialog=Once will cause to ask only one once, and not repeatingly. Dialog=Linked would need a 4 prim object, with buttons named 'Reset', 'Size' and 'Color'. The Allow= statements change the default permissions.
