{SOLVED} [1.12.2] Game crash when right-click on earhBlock with Seeds

[IlTosaerba]

I everybody,

 

I'm making a mod and I'm following shadowfacts' tutorial.

 

Today I wanted to da a simple crop, so following this tutorial I made my corn crops.

 

Everythink work except for one thing. When I righ-click on a block with my seeds the game crash.

 

My project: https://github.com/IlTosaerba/Minecraft-1.12.2-WLLC-Mod/tree/IlTosaerba-WLLC-1.12.2]-Mod   (The "resource/assets" has been exploded 'cause GitHub don't permit the upload of +100 files and I don't understand how to create folders and so on)

• Blocks.CROP_CORN is null at this point. You cannot pass null for that parameter though.

@diesieben07 We should have this problem in the common problems list. I vaguely recall trying to ping you about it before.

How do you want to add it? "Don't pass null to things that should not be null"?

This issue is only ever a problem "when someone is creating crops" (90%+). Usually it's someone passing an item to a block constructor, but only about 60-40.

I'd write it as...

"Do not pass items to block constructors, if passing blocks to items, insure blocks are initialized first. This is a very common issue when making crops and seeds. Use the debugger to verify your references are not null."

Or

"When passing block and item references to constructors, insure correct order of operations. Use the debugger to verify your references are not null. Blocks should be initialized before items."

The specific issue you are describing is solved if you comply with the recommended approach of creating your blocks and items in the registry events (block registration fires first).

Yes, I agree. But even so I still see people doing this wrong. Like I said, I've seen people pass their item reference to their block (heck I once saw someone do both: item ref to the block and the block ref to the item!). Literally every time I see a thread with the word "crop" or "seeds" in the title I know what the problem is, and it's this problem. The registry events have (somehow) not made this common issue go away.

Maybe the static initializer should be added to the code style parts...? 

There are still far too many people doing that...?
