ExecuteInEditMode Deciding when to update

This is the first time I try to write a script that runs in Edit Mode

What I can't wrap my head around is how to decide when to update without keeping a double for each flield like

Code (csharp):

1. private Int oldvalue;
2. public int newvalue

and Compare all my field values, which is very time consuming and overall inefficient.

Usually I would use properties like this

Code (CSharp):

1.     private bool changed = false;
2.     private int test = 0;
3.     public int Test {
4.         get
5.         {
6.             return test;
7.         }
8.         set
9.         {
10.             if (test != value)
11.             {
12.                 changed = true;
13.                 test = value;
14.             }
15.         }
16.     }

but unity does not display properties in the UI for editing

In the end I will need to destroy and recreate 100's if not 1000's of objects when an update is needed.

Will any of you point me in the right direction on how to this fast and effectively?

 

You can edit properties if you write your own editor that draws them. then you could also let the editor perform the update, removing the need for execute in editor.

 

is this what you are talking about?
