G'day,
One way would be to do it like this :-
In your init place
Code:
squad_timeout = True;
Publicvariable "squad_timeout";
In your trigger condition field put
and in your script put this at the start
Code:
if (!(squad_timeout)) exitwith {hint "You must wait for 5 minutes before you can call a new squad";};
squad_timeout = False;
Publicvariable "squad_timeout";
and this at the end of your script after your spawn code
Code:
sleep 300;
squad_timeout = True;
Publicvariable "squad_timeout";
Forgive any errors not at my Arma machine at the moment, but that should do the trick mate.
Cheers
Hendo
