[1.11] TileEntity: adding an enum value to the NBTTagCompound?

[Kander16]

Hi,

 

I'm making a barrel which can contain a lot of fluids. In the tileentity of the barrel I have an enum variable (from the enum FluidTypes), with the value of the current type of fluid inside the barrel.

I was wondering if there was a way to write to and read from the NBT for this value?

 

Thanks.

You can save the Enum as a string.

 

Call

enum#name()

, to get a String representation of the enum.

To convert back, use

Enum__.valueOf(String)

.

 

Example:

String estr = EnumHand.MainHand.name();

Reverse:

EnumHand hand = EnumHand.valueOf(estr);

Of course, if an enum is not found for that string, it will be null, so be sure to null-check.

 

All you really need to do then is save the string to NBT.

Actually, Enum#valueOf() will throw an IllegalArgumentException if the string isn't known. Checking for null won't help; you need to wrap the call in a try/catch block.
