Which way is better for organizing/easy access?

[lean crest]

Putting variables in batches according to their types, or their use cases?

1.
public float f,h,j; // Primitive types
float f1;
[HideInInspector]public float f2, f3;
public int f,h,j;
int f1;
bool brrr;

public Class1 fsa; // Self made classes here
public Class2 fdsln;

public Transform ffff; // Unity Components/behaviours
public GameObject fndsjfsd;

public Vector3 fsadas; // Unity Data types
public Quaternion fdsfs;

2.
float animationSpeed;
Animator animator;
string[] animationNames;
int[] animationIndices;
bool animationIsPlaying;

float cardSpeed;
Transform cardTransform;
Card cardScript;
bool isCardOut;

2. is the way I go about it
   Just looks clean both in code and in the Inspector

Looks even more organized when used with headers https://docs.unity3d.com/ScriptReference/HeaderAttribute.html

true but there are many times when you just need many individual variables

how to deal with them

[civic cobalt]

wrap them in a class if they are to be used multiple types
Serialize that class so you can get a collapsable element
You can also make a property attribute so it can done with a group of elements

oh

i didn't know you can even serialize classes for inspector

that's a really nice info

u can use [Header]

That was already suggested by UV: #1139558304251650069 message

[lean crest]

I've tried using headers but I don't really like em

serializing classes might be the one I would love to use tho

[unborn folio]

serializing ?

how

You can make the editor serialize (almost) any normal class by giving it the System.Serializable attribute.
