Please Help me!

[BusyBeever]

If you have a request please add the version to it

[Draco18s]

I don't see anything wrong with your read/write NBT methods, but holy hell your class names are a mess.

ModBlockTileEntity.java

isn't the tile entity class as I first expected, then neither was

ContainerModTileEntity.java

The "best" naming convention will be one that everyone working on Minecraft is familiar with:

BlockWhatever

,

TileEntityThingamajig

,

ContainerWhatThing

, etc.

 

Also,

Class.java

?  Seriously?

[mattyj1231]

Do you know why its not working?
