RequestPermissions

llRequestPermissions

Summary

1/2 Bugs

Function: llRequestPermissions( key agent, integer permissions );

0.0	Forced Delay
10.0	Energy

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[1]
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
PERMISSION_RETURN_OBJECTS	0x10000	Used by llReturnObjectsByOwner and llReturnObjectsByID to return objects from parcels	Cleanup	Owner, Group Owner

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.
• The menu-option "Stop Animating Me" will release certain permissions (PERMISSION_TRIGGER_ANIMATION and PERMISSION_OVERRIDE_ANIMATIONS), if the script which holds these permissions is in the same region as the agent, and the script is not attached to the permission granter.
• 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).
  • To request two or more permissions at the same time, use the bitwise OR (|) operator, e.g.:

    llRequestPermissions(AvatarID, PERMISSION_TAKE_CONTROLS | PERMISSION_TRIGGER_ANIMATION)
    

• Permissions are requested and granted separately for each script, even if they are located in the same object.
• 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, whichever 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.
• Permission requests and changing state ...
  • Requesting a permission in one state, then changing state before the agent response, will cause run_time_permissions to be fired in the new state once the agent responds.
  • Requesting only auto-granted permissions in one state, then immediately changing state, will never fire run_time_permissions.

Examples

Request permission to animate an avatar

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");
    }
}

To request two (or more) permissions at the same time, use the bitwise OR (|) operator.

llRequestPermissions(AvatarID, PERMISSION_TAKE_CONTROLS | PERMISSION_TRIGGER_ANIMATION);

- or -

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).
