<lsl> // this script will add 1 to x every other time it is touched.

integer x = 8; // this makes an integer set to the value of eight when the script starts integer y = FALSE; // you can set integers to TRUE or FALSE too

                   // in this example, y is going to be used to see if the last time the object
                   // was clicked 1 was added to x.
                   // basically by setting y to TRUE and FALSE the script will be able to add one
                   // to x every other time

default {

   state_entry()       // we'll just have the script say the value of x when it loads
   {
       llSay( 0, "x has a value of: " + (string)x );
   }
       
   touch_start(integer total_number)
   {
       if ( y == FALSE )           // first time clicked y would be false so that's when 1 
                                   // should be added to x                                    
       {
           x = x + 1;              // adding one to x here

           llSay( 0, "1 added to x. x is now: " + (string)x ); 
                                   // this will make the object say the value of x.
           y = TRUE;               // since this started with y being FALSE, now it's time
                                   // to make it TRUE so the next time it's clicked it does
                                   // something different.
       }
       
       else if ( y == TRUE )       // do this stuff is y is TRUE
       {   // object says this
           llSay( 0, "nothing added to x this time. x is still: " + (string)x );

             y = FALSE;          // since nothing was added this time then set y back to FALSE
                               // so something gets added next time.
