You want your block to display in the inventory? It needs an inventory variant. QED

You don't have an inventory or normal variant in your blockstate file.

Yes. Read your error:

Yes

Well, that's wrong, obviously. You want to register with events? Write an event handler. http://mcforge.readthedocs.io/en/latest/concepts/registries/#registering-things

You're tracking a total amount of dust found, but you're returning it before every slot has been checked (or if a slot is the wrong item, returning 0).

What was the value of state.getBlock() and the value of blockIn?

Sooo...examine the variables at that point. Is the block the desired block? Is the event silk touch (or not)?

Set a breakpoint somewhere else, like at the top of the event handler method. Your goal is to get the program to halt and let you examine why it is NOT going into a specific path, not put the break inside the path you want and then complain on the forums that it didn't go there. We already knew that.

Yeah, the name changed. At least twice. EnumChatFormatting is the only one I remember.

Ah, yes, you can do it that way too. I did things the way I did things because it worked for me. I wanted to treat my codebase as "one mod" as they were all related to each other, but distribute as separate mods, so people could pick and choose. You should be able to, but I don't know how.

Ah, yes. You're correct. I saw the first return and missed that one

First item in the backpack is a rock. Not reagent item. Next! Second item in the backpack is a reagent item. int total = 0 + stack size. Return total! All done! (Hey...what about the 3rd, 4th, and 5th items?)

Pretty much. getSlots() tells you how many slots there are (0-indexed) and getStackInSlot(index) gets the stack in that slot.

Compiled things work just fine.

I don't? Seriously, inside Eclipse, I don't worry about it.

I never tried to put them inside my resources directory.

There's a lot of functions. They do things. To make it easier to perform OGL commands. You want to know HOW they work, you're going to have to open the class up and read...

I'm not sure :\

It exists, but it will be overwritten without notice.

All data is server side, the client merely maintains a copy. You want to change the data...? Change it on the server.

I'm not sure. I just know that what I have works. Show your folder structure and gradle.build file again?

Its a wrapper around OpenGL commands. That's it.

§c can be replaced with EnumChatFormatting.RED
