OOP guidance (for myself)

I'm having a real tough time grasping OOP for a project in school using Monogame, like I can't quite figure out how to reference variables / sprites and such from other classes, maybe i'm just being silly but I was looking for any in depth OOP guides, tips or even talks from people

i mean, tbh, the best way to understand and learn OOP is just through practicing i started with JS classes which helped me get some basic understanding and some intermediate as well right now i am doing C++ which is also kinda teaching me some

it would be much more helpful if you could provide help here, so others can learn from it too. I do feel the need to point out that if you're trying to sell anything by asking folks to DM you, and we get reports of this, it's considered a violation of #📝rules 7 If you're just being helpful (for free) and prefer one on one contact, that's fine

like I can't quite figure out how to reference variables / sprites and such from other classes,
make sure those varables are public. public methods and properties are accessible from outside the class by anyone. idk about c# but there is something called friend in c++ which can grant access to private props and methods as well in case if that helps u in cpp , classes has all methods and props private by default . which means 
class Vector {
  int x, y;

  Vector(int x, int y): x(x), y(y) {}
}
class Vector {
  int x, y;

  Vector(int x, int y): x(x), y(y) {}
}
here the x,y and even the constructor is private. so i have to make them public by doing 
class Vector {
public:
  int x, y;

  Vector(int x, int y): x(x), y(y) {}
}
class Vector {
public:
  int x, y;

  Vector(int x, int y): x(x), y(y) {}
}
so incase this is same for c# make sure to make them public

bro really went ahead and tried even though I just told him... you may want to block him

already done haha thanks yup theyre public, i guess it's my fault for starting to code in the main game1 folderi nstead of branching and making a class beforehand, i tried even making my new class a child of the main one and still couldnt grab certain aspects that i needed of it though

u can try searching up and see if others have faced same issues or not

for instance, i want to try get a hold of the gameState variable from the main program to make if conditions etc in the new class

also , since this is web dev focused server, it is less likely to get help here there are c# specific servers out there, you'll get better help from there
glutonium

if u just go here and search c# you'll see

unluqy
unluqy•3w ago
uhh
glutonium
glutonium•3w ago
is this inside the Game1 class?
unluqy
unluqy•3w ago
i defined it under my game1 class when naming the other attributes but since i made the screenManager a child of that, i shouldve been able to reference it yeah

unluqy
unluqy•3w ago
does not exist in current context
glutonium
glutonium•3w ago
i see that your Game1 is a public class while screenManager is internal class, could that be a problem?
glutonium
glutonium•3w ago
