Caveats

  • Permissions do not accumulate.
    • If a permission was requested with a previous call to this function and granted, then in subsequent call was not requested, that permission is released (lost).
  • Scripts may hold permissions for only one agent at a time. To hold permissions for multiple agents you must use more then one script.

Examples

Request permission to animate an avatar <lsl>default {

   touch_start(integer detected)
   {
       llRequestPermissions(llDetectedKey(0), PERMISSION_TRIGGER_ANIMATION);
   }
   run_time_permissions(integer perm)
   {
       if (perm & PERMISSION_TRIGGER_ANIMATION)
       {
           llStartAnimation("sit");
           llOwnerSay("animation will end in 5 seconds");
           llSetTimerEvent(5.0);
       }
   }
   timer()
   {
       llSetTimerEvent(0.0);
       llStopAnimation("sit");
   }
}</lsl>

Notes

A dialog is presented to the agent to grant these permissions except for a few cases:

  • If agent is sitting on object - Control and Camera tracking permissions are granted without notification upon request.
  • If object is attached to agent - Control and Attach permissions are granted without notification upon request.

Regardless if a dialog is displayed you should always use the run_time_permissions event instead of depending upon this quirk.
