Help with Controls?

I'm new to scripting with LSL, and I wanted to make a remote controlled object using llTakeControls( ).

My problem: My "control( )" event is only getting called for CONTROL_FWD and CONTROL_BACK - the av keeps doing everything else.

Here's a simple test code I tried - control() is never entered except for those two cases. (I had more "if" cases for the other CONTROL_XXX level settings - I cut them out for brevity here. But the llWhisper in control() is only called for fwd and back inputs.)

    

default
{
    state_entry()
    {
        llRequestPermissions(llGetOwner(), PERMISSION_TAKE_CONTROLS); // get permission to take controls
    }

    run_time_permissions(integer perm) 
    {             // permissions dialog answered
        if (perm & PERMISSION_TAKE_CONTROLS )  
        {         // we got a yes
            integer conts =  CONTROL_FWD | CONTROL_BACK | CONTROL_LEFT | CONTROL_RIGHT | CONTROL_LBUTTON;

            llWhisper(0, "Grab controls " + (string)conts );
            
            llTakeControls( conts, TRUE, FALSE ); 
        }
    }
    
    control(  key name, integer levels, integer edges )
    {
        llWhisper(0, (string)levels + (string)edges );
        if( levels & CONTROL_FWD )
        {
            llWhisper(0, "released");
            llReleaseControls( );
        }
    }
}

Can anyone point out what I'm doing wrong here?

If you include the following piece of code:

if( levels & CONTROL_LEFT )
        {
            llWhisper(0, "released");
            llReleaseControls( );
        }

in your program then the program does report released when the CONTROL_LEFT key is pressed. The CONTROL_LEFT key is shift-left-arrow, not just left arrow, assuming you are not in mouselook. To react to a plain left arrow the constant that should be used is CONTROL_ROT_LEFT.

The LSL Wiki, at http://secondlife.com/badgeo/wakka.php?wakka=HomePage, is fairly clear on this subject, just look up llTakeControls and the control event.

Questions about scripting would be better placed in the scripting forum instead of the building forum.
