Using two states can sometimes be an elegant solution to on/off.

  • Original framework 04-16-08 by Toady Nakamura
  • Light call modified from Simon Kline's classes "Scripting from Scratch"

<lsl> vector color = <1.0, 1.0, 1.0>; float intensity = 1.000;// from 0.0 up to 1.0 float radius = 10.000;// from 0.0 up to 20.0 float falloff = 0.750;// from 0.0 up to 2.0

default { 

   on_rez(integer start_param)
   {
       llResetScript();
   }

   touch_start(integer num_detected)
   {
       llSetLinkPrimitiveParamsFast(LINK_THIS,
           [PRIM_POINT_LIGHT, TRUE, color, intensity, radius, falloff,
           PRIM_FULLBRIGHT, ALL_SIDES, TRUE]);

       state lightOn;
   }

}

state lightOn { 

   on_rez(integer start_param)
   {
       llResetScript();
   }

   touch_start(integer num_detected)
   {
       llSetLinkPrimitiveParamsFast(LINK_THIS,
           [PRIM_POINT_LIGHT, FALSE, color, intensity, radius, falloff,
           PRIM_FULLBRIGHT, ALL_SIDES, FALSE]);

       state default;
   }

} </lsl>
