Accessing enum from editor script returns null

Question

 /// In script:
 enum city { London, New York, Toronto }
 
 /// In Editor script:
 function OnInspectorGUI
 {
        Debug.Log( target.city );
 }

It returns null, when I'm expecting it to return the enum.

An enum is like a type. You just declared it but your script is not using it.

What you need to do:

 /// In script
 enum City // use uppercase
 {
     London,
     NewYork, // you cannot use whitespace
     Toronto,
 }
 
 City myCityVariable = City.Toronto;
 
 /// In editor script
 function OnInspectorGUI
 {
        Debug.Log( target.myCityVariable );
 }

But if you want to log this enum as a type, you need to access it as a class-variable:

 Debug.Log( YourScript.City.ToString() );

where YourScript is the name of your script (in fact the name of the class defined in your script).

I have no problem getting a variable using the enum, but how can I get a list of the items in that enum?

Basically what I want to do is display a toolbar that will let me choose amongst the enum values, but the toolbar interface element requires a string array of the items, so I need to get all the enum values to be able to convert them into a string.

System.Enum.GetNames(typeof(YourScript.City))

See Enum.GetNames Method

Cool. I got it to work. Rather than using your example of referencing the enum, I needed to reference the variable instance of the enum, so…

System.Enum.GetNames(typeof(YourScript.myCityVariable))

Thanks Nicolas! :)
