Hello there,

I am working on this RPG game in Unity and I’ve come to the point where I need to develop the system for handling events. The thing is, I have a class called “interactable”, and that class is supposed to serve everything from NPCs to treasure chests and doors. Programming the behaviour of each instance in the instance itself (in the case of Unity, in the prefabs’ scripts) is, however, definitely not the way to go. I would like a way to express how interactables should behave (NPC dialogue, items contained in chests, etc.) from an external file (probably a text file) and load the pertinent interactable data depending on the room (scene) I’m in. Any tips on how to start on that?

Moreover, I need a way to handle the events that these interactables will trigger. I’ve looked at this reference for event handlers in Unity with C#: http://www.everyday3d.com/blog/index.php/2010/10/04/c-events-and-unity3d/ , which already helped me a bit, but I’ve thought of basically two ways to implement this in a game-wide system: Either one event controller per scene, which would have information on the events that could happen on that scene and handles all of it (activates listeners, etc.); or a game-wide event controller (a singleton), with information about events from the whole game. Which do you think is better? Or would you rather go with another alternative?

Thanks in advance for the replies
