Send the actual code and error

First error in the list anyways

[devout jacinth]

It's source engine btw

[cunning mirage]

you surely did int& instead of int* = nullptr; did you?

[devout jacinth]

nope

where would I have to put int& anyway

or int* = nullptr

into the declaration of the int or the reference from another class

[cunning mirage]

the reference from the other class

anyway show code please!

[devout jacinth]

I am doing the reference in the function if that helps

I just wan't to add 1 to the int everytime the function is called. And the int is in the other class than the function

You still haven't shared any code

Make a small example that reproduces the problem

[devout jacinth]

filefromclass1.h

Class 1 : public base
{
public:
  int xyz = 0
};

filefromclass2.cpp

#include "filefromclass1.h"
#include "filefromclass2.h"
#include "base.h"

void class2::create(void)
{
  xyz = xyz + 1;
  
  some other code here
}

And yeah. Idk how to make that thing in class 2 work
