Unity - custom struct name in inspector based on struct' filed(s)

Question

I have a custom serializable struct stored in as a list elements. When only one field of a struct is public

[System.Serializable]
public struct MemoryMoment {
    float Importance;   //Subjective
    Person who;
    Room where;
    string when;
    string what;
    //string why;
    public string Descr;

    public MemoryMoment (float importance, Person who, Room where, string when, string what) {
        this.Importance = importance;
        this.who = who;
        this.where = where;
        this.when = when;
        this.what = what;
        //this.why = "UNUSED";
        this.Descr = where.Type.ToString () + " " + when + ", " + who.Name + " " + what;
    }
}

then this whole struct is named in inspector after that element

but when more than one field in struct is public

[System.Serializable]
public struct MemoryMoment {
    public float Importance;    //Subjective
    Person who;
    Room where;
    string when;
    string what;
    //string why;
    public string Descr;

    public MemoryMoment (float importance, Person who, Room where, string when, string what) {
        this.Importance = importance;
        this.who = who;
        this.where = where;
        this.when = when;
        this.what = what;
        //this.why = "UNUSED";
        this.Descr = where.Type.ToString () + " " + when + ", " + who.Name + " " + what;
    }
}

then the struct is named just "Element N"

How can I provide custom inspector name for my struct?

Ie something like this:

[NameInInspector]
string n = "(" + Importance.ToString() + ") " + Descr;

Answer 1

It's caused by how Unity serializes the MemoryMoment struct.

Basically, if there's a string as the first declared field in the struct, then Unity will use its content to "name" the Element of the list.

So, if you want to read the content of Descr instead of Element X you just need to move the declaration public string Descr; on top of all declarations:

[System.Serializable]
public struct MemoryMoment {
    public string Descr;
    public float Importance;    //Subjective
    Person who;
    Room where;
    string when;
    string what;
    //string why;

    public MemoryMoment (float importance, Person who, Room where, string when, string what) {
        this.Importance = importance;
        this.who = who;
        this.where = where;
        this.when = when;
        this.what = what;
        //this.why = "UNUSED";
        this.Descr = where.Type.ToString () + " " + when + ", " + who.Name + " " + what;
    }
}
