Detecting a Double Click

Hi There.
This allows you to get double clicks from a user. makes interfaces a bit easier to create! warning.. in laggy areas this may not be too good to use.

Enjoy!

integer poke = FALSE; 
default
{
    touch_start(integer x)
    {
        if(poke){
             llSetTimerEvent(0);
                 poke = FALSE;
                 //double clicked
        }
        else{
             poke = TRUE;
            llSetTimerEvent(0.5);//change this depending on how fast you give them to click again
        }
    }
    timer()
    {
        llSetTimerEvent(0);
        poke = FALSE;
        //single clicked 
    }
}

I was using this code to flip a playing-card prim. It's mechanism goes between two states like the script originally posted does. This gives an option to handle a single, double, or triple click though... Don't know if that's useful or not.

integer clicks; integer flipped; rotation topward = <0,180,0,0>;
rotation backward = <0,0,0,0>;

handleflipping ()
{
            if (flipped==FALSE)
            {
                llSetRot (topward);  flipped = TRUE; return;
            }
             
            if (flipped==TRUE)
            {   
                llSetRot(backward);    flipped = FALSE;
            }
}

default
{  
    state_entry ()
    {
    }
    
    listen (integer chan, string name, key id, string mess)
    {
        if (chan==28)   // saying anything on channel 28 flips this card over.
        {
            handleflipping();
        }   
    }
    
    timer ()
    {
        clicks=0;
    }
    
    touch_start(integer total_number)
    {
        clicks++;
            if (clicks==2) {  // the double-click is determined by the 2, of course.
        if (clicks==2) { clicks=0; }      
        handleflipping();
        }
    }
}
