Summary

Function: llRequestPermissions( key agent, integer permissions );

Ask agent for permissions to run certain classes of functions.

• key agent – avatar UUID that is in the same region
• integer permissions – Permission mask (bitfield containing the permissions to request).

Script execution continues without waiting for a response. When a response is given, a run_time_permissions event is put in the event queue.
Constants Action Category Granter Automatically granted when…
PERMISSION_DEBIT 0x2 take money from agent's account Money Owner
PERMISSION_TAKE_CONTROLS 0x4 take agent's controls Control Anyone sat on, attached
PERMISSION_TRIGGER_ANIMATION 0x10 start or stop Animations on agent Animation Anyone sat on, attached
PERMISSION_ATTACH 0x20 attach/detach from agent Attachment Owner or Anyone attached
PERMISSION_CHANGE_LINKS 0x80 change links Link Owner
PERMISSION_TRACK_CAMERA 0x400 track the agent's camera position and rotation Camera Anyone sat on, attached
PERMISSION_CONTROL_CAMERA 0x800 control the agent's camera
(must be sat on or attached; automatically revoked on stand or detach) 		Camera Anyone sat on, attached
PERMISSION_TELEPORT 0x1000 teleport the agent Teleport Anyone
PERMISSION_SILENT_ESTATE_MANAGEMENT 0x4000 manage estate access without notifying the owner of changes Estate Owner
PERMISSION_OVERRIDE_ANIMATIONS 0x8000 configure the overriding of default animations on agent Animation Anyone attached

Caveats

  • A dialog is presented to the agent to grant these permissions except when granted automatically as shown in the table above.
  • If object is attached to agent, "automatic" permissions are granted without notification upon request.
  • Permissions persist across state changes.
  • Regardless of whether granting is automatic, you should always use the run_time_permissions event. Granting permissions takes time, and you shouldn't assume it's completed until the run_time_permissions handler gets invoked.
  • Permissions do not accumulate.
  • It is currently not possible to request no permissions at all (see Issues below); as a workaround llResetScript can be used.
  • Scripts may hold permissions for only one agent at a time. To hold permissions for multiple agents you must use more than one script.
  • The result of granting permissions affects the return of llGetPermissions and llGetPermissionsKey immediately, despite the run_time_permissions event being queued, or dropped if the object's event queue is full.
  • Permission request dialogs never time out.
    • If a script makes two permission requests, which ever response is last is considered the granted permissions.
  • The viewer limits permission requests from any agent to any other agent to 5 dialogs in 10 seconds

Examples

Request permission to animate an avatar 

default
{
    touch_start(integer num_detected)
    {
        key id = llDetectedKey(0);
        llRequestPermissions(id, PERMISSION_TRIGGER_ANIMATION);
    }
 
    run_time_permissions(integer perm)                                  
    {
        if (perm & PERMISSION_TRIGGER_ANIMATION)
        {
            llStartAnimation("sit");
            llSay(PUBLIC_CHANNEL, "Animation will end in 5.0 seconds.");
 
            llSetTimerEvent(5.0);
        }
    }
 
    timer()
    {
        llSetTimerEvent((float)FALSE);
 
        llStopAnimation("sit");
    }
}

To request two (or more) different permissions at the same time you can using the bitwise OR (|) or precompute the value. 

llRequestPermissions(AvatarID, PERMISSION_TAKE_CONTROLS | PERMISSION_TRIGGER_ANIMATION);
 
integer perms = PERMISSION_TAKE_CONTROLS | PERMISSION_TRIGGER_ANIMATION;
llRequestPermissions(AvatarID, perms);

Notes

When an agent grants a script non-automatic permissions they will receive a notification (in chat) of - The name of the object that contains the script that has been granted perms, The name of the owner of the object, The location of the object in the order - Region name at position - and a statement of what permissions were granted. If the script that holds the permissions is in a child prim the name will be that of the child prim (not the object (root)) and position will be its local position (relative to its root).
