Double Tapping

I know the theory behind double tapping a direction to do an action...by setting an event timer, I just dont know the actual script code, can anyone help?

here is a rough idea there will just be a small delay for one click

integer click;
default
{
    touch_start(integer num)
    {
        llSetTimerEvent(0.5);//time between clicks
        if (click)
        {
            llSetTimerEvent(0.0);
            click = FALSE;
            //code here for double
            llOwnerSay("double click");
        }
        else click = TRUE;
    }
    timer()
    {
        llSetTimerEvent(0.0);
        click = FALSE;
        //code here for single click
        llOwnerSay("Single click");
    }
}

There's an example under llGetAndResetTime in the sripting wiki (the old wiki at techrealms and rpgnet ... not sure its on the new wiki) that can be adapted without too much effort; also I think somebody's already posted a doubleclick script either here or in the library - search it out!

default
{
    touch_start( integer total_number )
    {
        float elapsed = llGetAndResetTime();
        float deadline = 10.0;

        if ( elapsed >= deadline )
            llWhisper( 0, "I'm sorry, you were too slow: " 
                          + (string)elapsed 
                          + " seconds" );       
        else 
            llWhisper( 0, "Yay!  You beat the deadline by " 
                          + (string)(deadline - elapsed)
                          + " seconds" );
    }
}

I was looking for double tapping a direction, not double clicking :/ Ill try to use this, should work the same way, but I would still appreciate a soling script code if anyones feeling generous
