My tests determined that the key returned when an agent control is caught is not the key for that agent, but is the object owner's key. If more then one script is used in the same object to hold permissions for multiple agents simultaneously, control may be triggered in all scripts but there is no way to know which agent actually caused the trigger.

There are some bugs when you put two scripts in the same prim and call LlTakeControls(), the '''id''' may not be the intended one. See [http://jira.secondlife.com/browse/SVC-3187 SVC-3187].

Description

! Event: control( key id, integer level, integer edge ){ ; }
15 Event ID
0.05 Delay

Result of llTakeControls library function call and user input.

• key id – avatar UUID
• integer level – bitfield of CONTROL_* flags, non-zero while one or more keys is being held down.
• integer edge – bitfield of CONTROL_* flags, non-zero when one or more keys have been just pressed or released.
Constant Value Description
CONTROL_FWD 0x00000001 Move forward control (↑ or W)
CONTROL_BACK 0x00000002 Move back control (↓ or S)
CONTROL_LEFT 0x00000004 Move left control (⇧ Shift-← or ⇧ Shift-A [← or A in mouselook])
CONTROL_RIGHT 0x00000008 Move right control (⇧ Shift-→ or ⇧ Shift-D [→ or D in mouselook])
CONTROL_ROT_LEFT 0x00000100 Rotate left control (← or A)
CONTROL_ROT_RIGHT 0x00000200 Rotate right control (→ or D)
CONTROL_UP 0x00000010 Move up control (PgUp or E)
CONTROL_DOWN 0x00000020 Move down control (PgDn or C)
CONTROL_LBUTTON 0x10000000 Left mouse button control
CONTROL_ML_LBUTTON 0x40000000 Left mouse button control while in mouselook
(undocumented) 0x02000000 Avatar left rotation detected. Triggers llGetAnimation == "Turning Left"
(undocumented) 0x04000000 Avatar right rotation detected. Triggers llGetAnimation == "Turning Right"

Caveats

  • CONTROL_ROT_LEFT and CONTROL_ROT_RIGHT can be triggered when an object is selected or edited. If the user is running Viewer 2.0 and later, llGetAgentInfo will have AGENT_AUTOPILOT set in this case.
    • Sitting upon an object that takes control may also trigger CONTROL_FWD, CONTROL_BACK, CONTROL_DOWN and CONTROL_UP, depending on avatar position relative to the seat.
    • Autopilot control events can continue for a short time after AGENT_AUTOPILOT drops.
  • The 'levels' and 'edges' of the control() event both receive (CONTROL_FWD + CONTROL_BACK) (value 3) after teleport, effecting scripts that use this combination for faster movement. Calling llTakeControls() again after a llSleep(3) will filter this out.


Examples

default
{
    state_entry()
    {
        llRequestPermissions(llGetOwner(), PERMISSION_TAKE_CONTROLS);
    }
    run_time_permissions(integer perm)
    {
        if(PERMISSION_TAKE_CONTROLS & perm)
        {
            llTakeControls(
                            CONTROL_FWD |
                            CONTROL_BACK |
                            CONTROL_LEFT |
                            CONTROL_RIGHT |
                            CONTROL_ROT_LEFT |
                            CONTROL_ROT_RIGHT |
                            CONTROL_UP |
                            CONTROL_DOWN |
                            CONTROL_LBUTTON |
                            CONTROL_ML_LBUTTON |
                            0, TRUE, FALSE);
                            // | 0 is for edit convenience,
                            // it does not change the mask.
        }
    }
    control(key id, integer level, integer edge)
    {
        integer start = level & edge;
        integer end = ~level & edge;
        integer held = level & ~edge;
        integer untouched = ~(level | edge);
        llOwnerSay(llList2CSV([level, edge, start, end, held, untouched]));
    }
}

Notes

llGetRot in mouselook for an attachment returns the angle the avatar is looking in.

There are some bugs when you put two scripts in the same prim and call LlTakeControls(), the id may not be the intended one. See SVC-3187.
