enum index is out of range - Strange Issue With Custom Editor

Hi I have the following Enum:

Code (csharp):

1.  
2.     public enum ProtocolFamily : byte
3.     {
4.         Other                                               = 0,
5.         EntityInformationInteraction                        = 1,
6.         Warfare                                             = 2,
7.         Logistics                                           = 3,
8.         RadioCommunications                                 = 4,
9.         SimulationManagement                                = 5,
10.         DistributedEmissionRegeneration                     = 6,
11.         EntityManagement                                    = 7,
12.         Minefield                                           = 8,
13.         SyntheticEnvironment                                = 9,
14.         SimulationManagementwithReliability                 = 10,
15.         LiveEntity                                          = 11,
16.         NonRealTime                                         = 12,
17.         InformationOperations                               = 13,
18.         ExperimentalCGF                                     = 129,
19.         ExperimentalEntityInfomationFieldInstrumentation    = 130,
20.         ExperimentalWarfareFieldInstrumentation             = 131,
21.         ExperimentalEnviromentObjectInfomationInteraction   = 132,
22.         ExperimentalEntityManagement                        = 133
23.     }
24.  

and this in a custom editor:

Code (csharp):

1.  
2. // ProtocolFamily            
3.             protocolFamily.enumValueIndex = ( int )( ProtocolFamily )EditorGUILayout.EnumPopup( protocolFamilyLabel, ( ProtocolFamily )protocolFamily.enumValueIndex );
4.  

When I select ExperimentalCGF or above I get the error 'enum index is out of range'. Having experimented a bit it seems that if I set ExperimentalCGF to 18 it will work but 19 and above cause the error. It seems Unity is validating this value by assuming they are all numbered in order, e.g 18 items in my enum so if the value is above 18 then its BAD!!!
However this does not happen if i allow the default inspector view. The problem seems to be the SerializedProperty class (protocolFamily.enumValueIndex).

Does anyone know how I can fix this or get around it without using the default inspector?

Thanks

Karl


Edit:

Doh!
Of course its treating the enum values as an array, so 18 values!.
Fixed it by using

Code (csharp):

1.  
2. protocolFamily.intValue = ( int )( ProtocolFamily )EditorGUILayout.EnumPopup( protocolFamilyLabel, ( ProtocolFamily )protocolFamily.intValue );
3.  

 

I know C# is a lot more exacting in types, but what's wrong with:

Code (csharp):

1. protocolFamily = (ProtocolFamily) EditorGUILayout.EnumPopup( protocolFamilyLabel, (System.Enum) protocolFamily );

System.Enum is hopefully unnecessary, but *shrug*.

Edit: Yeah, System.Enum seems to be unnecessary.

 

Hi Louis. using serialised properties allows for changes to be recorded so you can do undo and redo operations. It's a nicer way of doing things than manually calling undo.register yourself.

Ah, I missed the part where you mentioned you were using SP (saw it now, derp). Glad you found a solution.

On a side note, is your undo working correctly? Even in very simple test classes, I can only undo to even-numbered steps.

 

What do you mean even numbered steps? It seems to be working. I have spent ages.getting it too work lol
