Point triggers have a forward direction (you can rotate them). There's a way in the editor to show their direction via an overlaid arrow, but I forgot how exactly (I think by right-clicking on one of the "show trigger" widgets).
After you move a character to the trigger, you can call CharacterLookFromTrigger(char, trigger) (Osiris) or CharacterLookFrom(trigger) (behaviour script) to make them look in the direction of the trigger.
