I just begin to learn the plugin and following the youtube tutorial, I am very confused about something here:
At 3:25, it comes a [Run.] , I understand it is end of the dialog. But is it a language command or is it just a command from Dialog system??? Does it has some rules to write such command???
It's just dialogue text. A common convention in games is to put player actions in brackets to separate them from text that the player speaks. Within the context of this conversation, this means the player is choosing to run instead of saying something. It doesn't actually make the player's GameObject run away; it's just a text description.
