Differences between Class and Struct Object
Hello!
I have a quick question to you guys. Is there any difference between Object created from Struct and Class ? Any kind of performance differences ? I've noticed that EE uses Structs not Classes therefore I'm curious about this. Why Structs not Classes ? I've heard that I should use Structs for some kind of 'smaller' objects like struct Vec2 {}; and Classes for 'bigger' like class Player {}; - is that true ? Is there any 'C++ standard' for this ? wink

RE: Differences between Class and Struct Object
Usually, structs are used to store data (like Vec2 storing an X and a Y position).
You would use classes to create objects in-game (storing both variables and functions).

Technically, a class is a struct though. By default, a struct has its access set to public, a class to private.
I don't think there would be any noticeable performance difference.

that's what I thought. thanks for the fast reply smile
P.S. if I have a overloaded constructor and operators in struct Color should it be still struct or class then ?

struct is the same as class in c++ except that it defaults to "public" while class defaults to "private" members and bases.

I always stick to struct because I list public members first in the "struct/class declaration"

However in Code Editor I've made "class" work exactly the same as C++ struct.

there is one difference I've found:
when you CAST() it doesn't cast to classes only STRUCT
