"Main" function?

Questions & Answers
1

I'm new to Unity! (though I'm getting the hang of it pretty fast!)

Anyway, in the past I have scripted many games in other languages and platforms, and I'm sure Unity is no exception here: Every game basically has a "Main" loop, where everything happens: Updating all the game objects, processing data like input etc...

I am wondering, where might I access the equivalent to such "Main" function in Unity? I am assuming each scene has its own Main or Update function, but I'm having trouble finding it.

I wish to do a few things when a scene loads.

Well, that's not a big problem for my project right now, because I could simply create a new GameObject and put those things in the Awake() function or something, and ta-da. But I was wondering if there is a more "official" way to do things on scene initialization.

There is no Main function in Unity; everything is component-based. Your solution (create an empty game object with a manager script attached) is the usual way of handling scene-wide initialization.

Having a Main() function would defeat the purpose of having an engine.

The engine is started by main and form there it calls the functions here when they are required:

If you are familiar with object oriented programming(which is in the best interest of all developers) understand that that for every script you make you also create a class by its name. When the engine calls update it calls MonoBehaviour.Update() in everyone of your classes.

How do you make a certian scene load first then?
