Check if trigger is active inside script

Hi!

Im sorry if this has been asked before, but I can not find the answer to this.

I am trying to make a script thats in a loop, terminate when a trigger is no longer active.

while {triggerActivated music} do {(playsound "prayer"), (player sideChat "test"), (sleep 210); if !(triggeractivated music) exitwith {player sidechat "bye bye"};};

As you guys can probably see, this will not work. So help would be appreciated
