//INSTRUCTIONS:  rename the script file to the name of your map, and place it in the same directory as your map.
//Along with your door, set up a nodraw brush, and convert it to atdm:mover_button.
//Create 2 atdm:target_callscriptfunction entities. give one a "call" "stateChange" key/val pair, 
//and the other "call" "stateCheck".  Give both your door and button a "target" spawnarg, and assign the value
//for it with the names of your atdm:target_callscriptfunction entities.
//the door target should correspond with the script entity with "call" "stateChange", and the button with the other.
//Make sure your door has spawnargs "trigger_on_close" "1", "trigger_on_open" "0", and "trigger_when_opened" "1".
//change the value of "snd_lockpick_pin_14" spawnarg of your door to the sound that you desire. (and make sure that your locks don't use pin14).
//set a "frob_peer" spawnarg on your door with the name of your button as its value.
//you are done!  note: additional functionality to stop the sound if door closing is interrupted may be added later :)
