I want my block to have 7 states, 1 for each direction and one meaning "no direction". What would be the best design choice?

 

• create a new Enum
  
• set the default as null (I'm afraid this would crash the game, not sure)
  
• something else (please, tell me what)
  

PropertyEnum

doesn't support

null

values. I think the best option is to create a new enum with the required values.

 

You'll probably want to include a method to get the corresponding

EnumFacing

for each enum value. Either mark it as

@Nullable

and use

null

for the "no direction" value or use

Optional<YourEnum>

as the return type and

Optional.absent()

(Guava) or

Optional.empty()

(Java for the "no direction" value.

 

Edit: Automatic smileys are annoying when talking about Java 8 in parentheses.

Create a new enumerated and have an explicit "unknown" or "none" value.
