Serializing MonoBehaviours

I’m sure this has been asked before but I was unable to locate an answer.

I would like to create a simple comment script. To allow an implementor to explain why/how the gameobject is constructed as it is.

Simple enough, but what I don’t want; Is for that component to be serialized with the gameobject when the project is built (Android/iOS/etc…).

The only info I could find was to wrap the class within #if UNITY_EDITOR. I would assume the component would still exist on the object but would have empty data? or a ‘missing’ component?

Unity - Manual: Conditional Compilationlink text

So for example if you attach this code to your Project :

public class PlatformDefines : MonoBehaviour {
  void Start () {

    #if UNITY_EDITOR
      Debug.Log("Unity Editor");
    #endif
    
    #if UNITY_IPHONE
      Debug.Log("Iphone");
    #endif

    #if UNITY_STANDALONE_OSX
    Debug.Log("Stand Alone OSX");
    #endif

    #if UNITY_STANDALONE_WIN
      Debug.Log("Stand Alone Windows");
    #endif

  }          
}

It will compile the code depends on the Build Settings. So for example if you build it Windows and check Assembly-Csharp.dll with reserved engineering Software the code would look like this :

using System;
using UnityEngine;
public class PlatformDefines : MonoBehaviour
{
	private void Start()
	{
		Debug.Log("Stand Alone Windows");
	}
}
