❔ How to use a variable across an entire class

WWowItsKaylie3/1/2023

I'm wanting to use the client var (at the end of Awake) in the Enter key case, so I can post a status when I press enter without redefining the variables every keypress. https://paste.mod.gg/byljqcyiagkv/0

Class fields are what you want

public class MastodonMonkePostView : ComputerView
{
  private MastodonClient _client;

  private void Awake()
  {
    ...
    _client = new MastodonClient(instance.Value, accessToken.Value);
  }

  ...
}

class fields are:
- private
- usually prefixed with _ or m_

So, if you'd also want the authClient to be a field, then write it as: private AuthenticationClient _authClient

You have to specify the type of the field, var cannot be used.

class fields can be public:

public class MyClass
{
  public string MyNamePUBLIC;
  private string _myNamePRIVATE;
}

public class OtherClass
{
  public void Test()
  {
    var instance = new MyClass();
    instance.MyNamePUBLIC = "Some Name"; // OK
    instance._myNamePRIVATE = "Other name"; // Compile error
  }
}

However, it is strongly advised to avoid public fields, as you allow other classes to change something in your class without you knowing it.

That is where properties come in. It is a wonderful feature of C#, which allows you to:
- see who references a given property
- control who can read the property (get its value)
- control who can write to the property (set its value)
- run extra logic before the value of a property is read or written to, e.g., log, filter and validate values, execute more complex logic

And here is the official documentation of C# fields: https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/fields

Remember, reading documentation is an essential skill for any developer

(you really don't want to be dependent on StackOverflow

Yup the Mastonet authentication docs were actually pretty intuitive once I looked at it
