Unity: Add Comments/Notes to a GameObject


Adding Comments/Notes to a GameObject

In order to add a note to a gameObject in Hierarchies window.

  • Create a script called “ThisIsComment”. Remove everything from the script and copy the following code to it:
using UnityEngine;
/// <summary>
/// Attach this script to any gameObject for which you want to put a note.
/// </summary>
public class ThisIsComment : MonoBehaviour
    public string Notes = "Comment here.";  // Do not place your note/comment here.
}                                           // Enter your note in the Unity Editor.
  • Attach this script to all of the gameObjects to which you want to add note (you can drag this script to the gameObjects or to use “Add Component” button in the corresponding Inspector window)

Note: Do not change the content of the script. To add your note, go to the Unity Editor and write your note there (not in the script!).

Obviously, each gameObject can have a different note with this method.

  • (Optional): To make your note stand out from the other components in the Inspector window, move the “ThisIsComment” script up. To do so, click on the script name and drag it below the Transform component.

Note: After moving the component up, Unity might warn you that “This action will lose the prefab connection. Are you sure you want to continue?”. Don’t worry. Select “Continue” and then click on the “Apply” button on the top-right of the Inspector in order to apply this change to it’s prefab.
