Setup

Rez a object to serve as root, recommended as the menu-background of the UI.

new script, name as 'uiMaster'. This is the default basic setup: <lsl>

</lsl>

new scripts (4 total), name as 'uiSlave:0', 'uiSlave:1', 'uiSlave:2' and 'uiSlave:3', which serve to speed up feedback significantly of the pseudo dynamic graphics.

<lsl> integer x;

default{

   state_entry(){
       x = (integer)llList2String( llParseString2List( llGetScriptName(), [":"], [] ), 1 );
       state Main;
   }

}

state Main{

   link_message( integer sn, integer n, string str, key k ){
       if( n == x ){
           list t = llParseString2List( str, ["|"], [] );
           llSetLinkPrimitiveParams( (integer)llList2String(t,0), 
               [(integer)llList2String(t,1),
                (integer)llList2String(t,2),
                    (key)llList2String(t,3),
                 (vector)llList2String(t,4),
                 (vector)llList2String(t,5),
                  (float)llList2String(t,6)] );
       }
   }

} </lsl>

uiFunctions

Initialization

Initializes UI Elements into lists. Goes through all child prims to identify them as being a UI element by their prim description. And includes them into global lists of link number, name and their UI type for: use in other functions debug saving time from re-searching entire linksets again and; preventing objects having hard-coded scripts which would defy the point of flexibility. <lsl> uiInit(){ integer y = llGetNumberOfPrims(); while( --y-1 ){ list Dat = llGetObjectDetails( llGetLinkKey( y ), [OBJECT_NAME,OBJECT_DESC] ); string lDesc = llList2String( Dat, 1 ); if( llGetSubString( lDesc, 0, 2 ) == "UI_" ){ uiLnk = (uiLnk = []) + uiLnk + y; uiNm = (uiNm = []) + uiNm + llList2String( Dat, 0 ); uiType = (uiType = []) + uiType + lDesc; } } } </lsl> Process Description uiInit Initializes by assorting all the child prims By Nexii Malthus

Click and Drag
