[1.8] BlockState use.

[Vebert]

Hi, I try minecraft forge for minecraft 1.8 with the new systeme of BlockState and I used it to save an integer.

 

So It's work well exept when the Integer is bigger than 15, in thoses cases my block save well but the block can only be destroyed on client side.

 

Finally I didn't understand two thing :

    - why it save the BlockState correctly when my Integer data is bigger than 15. (if it work as metadata in the past).

    - why the block block wasn't destroyed on the server side but work on the client side.

 

Sorry for my english (I'm french :'( )

Have a nice day, thank for your help.

a) BlockStates are still based on 4 bits. You cannot store more than 16 distinct values.

 

Uhm... no? Example:

Wasn't the whole purpose of BlockStates combining Block ID and metadata to one number to prevent wasting space on blocks w/o metadata usage?

Metadata is still only 4 bits.

States can hold more information then that, but metadata can only be 16.

If you want to store more use a tile entity.

It's one of those cases where Mojang.

Yes, you can have more BlockStates than 16. But only 16 of them can be based on metadata.

If you need more (like the fence) they need to be computed on the fly (getActualState in your Block).

 

Yeah, "powered" and "in-wall" look like two states that are gotten via looking at adjacent blocks or calling ancillary functions.  They're not going to be metadata stored.

 

Though, just looking at the documentation available on the wiki, it is unclear how the flower pot works (22 different states, one of which is 'empty').

Ahhh.  I wondered if it had gone TE.
