This is more of an Eclipse thing, but on my new PC I've setup a dev environment and I'm writing a mod, start the game and the blocks and items are not there. I've registered them, but they're not showing. I go into Mod Options and the mod says "State: Available", but nothing. It couldn't be something in the code.

 

Thanks!

You'll find that a decomp workspace is more useful than the dev workspace, so I'd recommend that you do the set up again, replacing 'dev' with 'decomp'.

What do you mean, "not there"? Not where? Not in the creative menu? Not visible when summoned successfully? Unable to summon or give?

 

To appear in the creative menu, items must not only be registered, but they must set a menu-tab (which may sometimes be done by a parent class).

 

For blocks, each block needs to explicitly define its ItemBlock and register that too (or else it will never exist as an item, which is okay for some blocks such as lava and air).

It's probably something with the code.

OMG I LAUGHED SO HARD

Yeah, I do use a decomp workspace. And I cannot even /give the item. If I cannot do that, it's obviously not in the creative menu. I'll check my code again, but I got it from my other mods, which do work on my old PC.

Please post your code and the console log.

$10 says you registered a block using GameRegistry.Register(Block) and didn't also register an ItemBlock.  Ergo your block does not have an item form, cannot be held, does not show in the Creative inventory, and cannot be given.
