Hiding or showing variables in inspector

Archived Forums Questions & Answers

I would like to ask if there is easy way to hide/show public variables in inspector depending on other variables.

Example:

if

public bool NeverFlees = true;

it would not show these options:

public int Morale = 100;
public int FleesOnMorale = 0;
public int FleesOnHealth = 10;

If there is no easy way of doing this, I think I could do something like this by extending the editor, right?

Unity recently added some attributes to help manage the inspector from inside the behaviour:

The attributes are still very poorly documented though.

As you correctly point out, you can extend the editor and have complete control of what gets shown, and when. For example:

[CustomEditor(typeof(MyBehaviourClass))]
public class MyEditorClass : Editor
{
    public override void OnInspectorGUI()
    {
        // If we call base the default inspector will get drawn too.
        // Remove this line if you don't want that to happen.
        base.OnInspectorGUI();

        MyBehaviourClass myBehaviour = target as MyBehaviourClass;

        target.NeverFlees = EditorGUILayout.Toggle("Never Flees", target.NeverFlees);

        if (target.NeverFlees)
        {
            // Draw the optional fields here
        }
    }
}

Thanks! And, thank you for the code sample too, I will be able to use it if the documentation isn't very good. (I should really look what could I do by extending the editor, but some why it looked scary for me all this time :D )

The documentation on basic editor stuff isn't too bad, but as things get more complex the documentation becomes less helpful.
