Alright, I've made a custom furnace before (but this was a while back) and what not, worked, yay, so I came back and decided to do something a little more complicated - only this time, two errors decide they want to exist (I did copy and paste the code from https://github.com/NealeGaming/nealecraft to save time).

 

This is the first error, in the BlockHydrogenSeparator code.

Here's the code for it: http://pastebin.com/gWMN5zzG (BlockHydrogenSeparator class)

 

Second error lies within this class, GuiHydrogenSeparator.

Here's the error: http://puu.sh/aJGZA/cef74319c3.png

Here's the code: http://pastebin.com/wyk5i2id

 

For reference, here's the container, tile entity and guihandler code:

Container class: http://pastebin.com/KxJEsdrc

 

Tile Entity class: http://pastebin.com/weQpWhE7

 

GuiHandler class: http://pastebin.com/nWf1JF1B

 

Any and all help is appreciated, thanks.

Look at your own line.

 

((TileEntity) world.getTileEntity(x,y,z).setGuiDisplayName(itemstack.getDisplayName());

 

Why are you casting an object of type TileEntity to TileEntity?

 

TileEntity does not have a method setGuiDisplayName(String name). You need to cast to your own TileEntity class (TileEntityHydrogenSeparator?). This is pretty basic java.

Thanks for the help.

 

What about the second error?

Again, really simple java (unless I'm mis-reading something completely).

 

You're trying to invoke a constructor for TileEntityHydrogenSeparator with InventoryPlayer and a TileEntityHydrogenSeperator as arguments.

 

Yet, in your your TileEntityHydrogenSeparator class you don't define any constructors, meaning you only have the default, no args constructor.
