I don't know how to display character names in dialogues.
And I also don't know how I can make the dialogue change according to the
character's name change.
Like...
???? - Hi
NPC - What is your name?
???? - [input]
[input] - [input]
NPC - So [input] is your name?
Well, \n[ID] will print the name of the actor with that ID.
