Hi there,

Another scripting newbie question... I'd like to make an Altimeter script for a flying object. Something that displays the height as text over the top of the object. I've got some code to display text but I'm not quite certain how to figure out the altitude. llGetPos?

vector pos = llGetPos();
llSetText("Current heigth: " + (string)pos.z, <1,1,1>, 1.0);

That should work.

That will give you your absolute height in the world, if you want your height above land you could use
CODE
float height()
{
    vector vPos = llGetPos();
    return vPos.z - llGround(ZERO_VECTOR);
}

or, if you wanted to get fancy and get your height above ground or water:
CODE
float height()
{
    vector vPos = llGetPos();
    if (llGround(ZERO_VECTOR) > llWater(ZERO_VECTOR))
        return vPos.z - llGround(ZERO_VECTOR);
    else
        return vPos.z - llWater(ZERO_VECTOR);
}

what if you wanted a tone at a user set altitude?

I would suggest
CODE

if (llGetPos() = whatever the height is)
{
    play sound
}



very nasty example code, I know... but I am only on my first cup of coffee!

you could also have the user set this height

have them say "setheight 1000" and that would set the comparison height for the if statement to 1000 meters.

perhaps after my 3rd cup, I will actually code this the right way!
