Quote from Alevice: Go

int and float are primitives, not classes tho (well, they are in c, java is more... complicated; and l;ets not get into javascript)

You're right, I was thinking of java where I pratically always use Integer in place of int :P However I think the galaxy editor Integer and Real are actually classes...

I think we can guess that the editor itself is a class, like pretty much everything within.

Pretty much the entire game I dare to assume... ;)

Yes of course the unit types are classes, they are like int, float, or rectangle.

A class is an object project. This object has many properties, called variables. This object can also do many actions, called methods.

Some methods and variables can be seen from outside, they are called public methods and variables. Some cannot, they are called private methods and variables.

A method is like a function, and a variable is still a variable, like the one you use normally also in the galaxy editor. Since it is a function, a method can use parameters and return values. Some method are used, for example, to set or get the value of private variables from the outside of the class.

The outside of the class is the rest of the world, in a simple example an int main(). You can define variables using a class, passing values or variables as parameter to an "inizialization" method, called constructor. Once a class is deleted, it invokes an other method, the so called destructor.

To clarify, a small example:

header.hpp:

class rectangle:
{
private:
   // Variables definition
   int x;
   int y;
   int height;
   int width;
public:
   // Methods definition: in order -> constructor, setter and getter
   rectangle(int h, int w, int pos_x = 0, int pos_y = 0);
   void setHeight(int h);
   int getWidth();
};

source.cpp:

#include <header.hpp>

// Constructor declaration
rectangle::rectangle(int h, int w, int pos_x, int pos_y)
{
   x = pos_x;
   y = pos_y;
   height = h;
   width = w;
}

void rectangle::setHeight(int h)
{
   height = h;
}
   
int rectangle::getWidth()
{
   return width;
}
