Editing flight assist script.

I would like to use the flight assist script someone kindly pointed me in the direction of, but as I know little about scripting, is there a way to hide or remove the "Release Keys" tab that appears at the bettom of my SL window? Is there a certain part of the code I remove?

//
// Flight Assist Example
//
// Highlights:
//    - altitude-based assist (lower altitude == less assist, higher == more)
//    - horizontal movement gets relatively less assist than vertical.
//    - HUD color indication of movement mode
//      - brown: not flying (i.e. earth)
//      - green: flying w/ assist
//      - white: hovering w/ assist
//      - black: assist disabled


// gAssistParams enables altitude-based flight assist.   Lower altitudes
// will get less momentum assist so that the client updating overhead
// is less likely to harm controllability.  Plus it's a pain to collide
// with a building at high speed in a damage-enabled area.
//
// see increaseMomentumAssist() for more info
//
list    gAssistParams = [ <1.1, 100, 200>, <1.25, 1000, 800>, <1.4, 10000, -1> ];

float   gMass;      // current mass (assuming it's constant; can imagine a variable mass assist tho :-) )
integer gMotor = FALSE; // Indicates whether momentum assistance is on
integer gAgentInfo; // A bitmask of the agent/avi current state
integer gReqKeys;  // A bitmask of the control keys required to operate
integer gReqPerms; // A bitmask of the required permissions to operate
key     gWearer;   // UUID of the avi who is wearing this attachment

Thank you in advance for any help you can give.

That tab is a necessary evil.

For the script to work, it needs to 'take controls' from you...and whenever a script does that in SL, that little 'release keys' button appears.

Unfortunately thats what I thought the answer would be. Oh well, I'm sure I can put up with it!

Ok, a different question on the same script....

If I want to use a menu (which luckily I have worked out) to turn on the flight script or release keys, I know I use the:

listen( integer channel, string name, key id, string message )
{
    if ( message == "Flight On" )

But at what point in the script do I use these for both a "flight on" and "flight off" message?

I hope you understand what I mean. Just to clarify I'm not using this as the intended HUD attachment, but in an item of apparel. I'm sure you can tell I'm new to this!

Thanks again.

you would put it that area

if (message == "Flight On"
{llWhatever call activates the flight assist;}
else if (message == "Flight Off"
{llWhatever call deactivates the flight assist;}

I think that is what you where looking for.

Let me know in game if it didn't help
