rule "1":
  @Event eachPlayer
  #!define _condition eventPlayer.isAlive()
  @Condition _condition
  smallMessage(eventPlayer, "Alive")
  waitUntil(not _condition, 9999)
  smallMessage(eventPlayer, "Aliven't")

rule "2":
  @Event eachPlayer
  #!define _condition eventPlayer.getCurrentHero() == Hero.GENJI
  @Condition _condition
  smallMessage(eventPlayer, "Genji")
  waitUntil(not _condition, 9999)
  smallMessage(eventPlayer, "Genjin't")

Expected output:

rule ("1") {
    event {
        Ongoing - Each Player;
        All;
        All;
    }
    conditions {
        Is Alive(Event Player) == True;
    }
    actions {
        Small Message(Event Player, Custom String("Alive", Null, Null, Null));
        Wait Until(Is Dead(Event Player), 9999);
        Small Message(Event Player, Custom String("Aliven't", Null, Null, Null));
    }
}

rule ("2") {
    event {
        Ongoing - Each Player;
        All;
        All;
    }
    conditions {
        Hero Of(Event Player) == Hero(Genji);
    }
    actions {
        Small Message(Event Player, Custom String("Genji", Null, Null, Null));
        Wait Until(Not(Compare(Hero Of(Event Player), ==, Hero(Genji))), 9999);
        Small Message(Event Player, Custom String("Genjin't", Null, Null, Null));
    }
}

Actual output:

rule ("1") {
    event {
        Ongoing - Each Player;
        All;
        All;
    }
    conditions {
        Is Alive(Event Player) == True;
    }
    actions {
        Small Message(Event Player, Custom String("Alive", Null, Null, Null));
        Wait Until(Is Dead(Event Player), 9999);
        Small Message(Event Player, Custom String("Aliven't", Null, Null, Null));
    }
}

rule ("2") {
    event {
        Ongoing - Each Player;
        All;
        All;
    }
    conditions {
        Is Alive(Event Player) == True;
    }
    actions {
        Small Message(Event Player, Custom String("Genji", Null, Null, Null));
        Wait Until(Is Dead(Event Player), 9999);
        Small Message(Event Player, Custom String("Genjin't", Null, Null, Null));
    }
