✅ Something is causing this to go into stack overflow

when I would run my code, it would always show a stackoverflow error and I narrowed down the problem to this file if I delete all the content of this class, the entire project runs fine But I can't figure out what's doing it

Presumably you can't delete that file without also removing the code which uses it?

Buddy•7mo ago

Are you using raylib?

AbOP•7mo ago

Yeah Sorry can you rephrase

canton7•7mo ago

Presumably you've got code which uses that GameManager class? So if you remove that class, the code which uses is needs to also be removed?

AbOP•7mo ago

I removed that code too The project builds fine as long as this file doesn’t have any code

canton7•7mo ago

Right, and are you sure it wasn't that code, which you haven't shown us, which was causing the issue?

AbOP•7mo ago

I doubt it because right now The project builds as long as the above code is gone. Or specifically I found every bit of it except int facing

canton7•7mo ago

There's nothing in the code you've shown which should cause a stackoverflow

AbOP•7mo ago

That doesn’t seem to cause an issue leaving it there

canton7•7mo ago

So I'm assuming it must be something in the way that code was being used, which you've had to change

AbOP•7mo ago

It’s possible but that would be even more confusing Because that code is gone now So how could it still be happening Should I just show the code left in the other file?

AbOP•7mo ago

this is the other file when all the code that references Game manager (except facing) is removed and this builds fine now as long asGameManager is cleared out

Buddy•7mo ago

What does call stack tell you? Call stack allows you to narrow down stackoverflow's

AbOP•7mo ago

how do I see it

Buddy•7mo ago

Run in debug mode From VS When the exception is thrown, it should break

AbOP•7mo ago

is this what you mean? I'm running in debug mode always

canton7•7mo ago

Oh, the Player constructor references GameManager?

AbOP•7mo ago

it shouldn't be

canton7•7mo ago

Oh, there we go public int X { get => X; set => X = value; } That's sugar for:

public int get_X()
{
    return get_X();
}
public void set_X(int value)
{
    set_X(value);
}

public int get_X()
{
    return get_X();
}
public void set_X(int value)
{
    set_X(value);
}

Properties acts basically like a proxy / middleman, it shouldn't set / get itself as that results in infinite recursion

canton7•7mo ago

If you want to write the getter/setter manually, you normally need a separate backing field:

private int _x;
public int X { get => _x; set => _x = value; }

private int _x;
public int X { get => _x; set => _x = value; }

So the getter/setter interact with the backing field, and the backing field actually holds the value. With what you have at the moment, the getter and setter just call themselves again and again You can also simplify the above to:

public int X { get; set; }

public int X { get; set; }

That tells the compiler to generate a hidden backing field for you, and implement the getter/setter as above

okay yeah this worked thank you so much that bug was mind boggling me to hell

The Rectangle can also be shortened to

public Rectangle Rectangle => new Rectangle(X, Y, 10, 200);

public Rectangle Rectangle => new Rectangle(X, Y, 10, 200);

oh sweet! good to know it's how I return collider info about the player

Buddy•7mo ago

Also this isn't Java, so you pretty much never need to use this. unless for certain cases. In that class it isn't needed except for the HP since the declared names are the same (case-sensitive).

AbOP•7mo ago

I'm trying to get out of the habit. It's just easier to visualize immediately class member variables by seeing "this" I know some people use underscore

canton7•7mo ago

Yeah, I like using this

Buddy•7mo ago

Conventions of using underscore in C# is only for backing fields, like this.

canton7•7mo ago

There are a ton of different conventions

Buddy•7mo ago

according to official Microsoft ones

canton7•7mo ago

You should try reading MS's own code -- there's a huge mix in there too

AbOP•7mo ago

yep turns out I did the same mistake in my Bullet class so every time the player fires, it spirals it again thanks again for the help!!
