Struggling with Multiblocks for 1.12.2

[MayusYT]

Hi, there! I want to create my own multiblock in Forge 1.12.2. The thing I struggle with is the pattern recognition. I already searched the Forum, but couldn't find what I wanted. Either it was outdated or it was not solved.

 

So I want to create a 3x3 hollow master-slave multiblock. The following problem is what i stumbled upon:
Assuming the yellowish rectangle is the controller, it is facing to north here. I want to get the facing on its left, that would be "West" in the picture.

But when the Controller is e.g. facing to the east, the block on its left is on the north facing:

My question is now: How can I get a facing RELATIVE to the blocks direction?
Thanks in advance.

EnumFacing#rotateY(rotateYCCW for rotating counter-clock wise)

Thanks for your reply. Unfortunately, the controller still can't determine the blocks correctly.

See this picture - the small arrows on the controller point to the direction they're facing to:

currentPos = currentPos.add(0, -1, 0);
currentPos = currentPos.offset(EnumFacing.byIndex(world.getBlockState(currentPos).getBlock().getMetaFromState(world.getBlockState(currentPos))).rotateYCCW());

^ that's the code I currently have. currentPos is the controller's position at first, then I subtract 1 on the y axis and rotate the facing counter-clockwise. I placed the stone block where currentPos is. As you can see, the block isn't always at the same position relative to the controller.

 

I have trouble with fixing this, any help will be appreciated!

Oh holy mother jesus christ, what the fuck is this garbage?

 

Why the ever loving crap are you calling getMetaFromState?

 

currentPos.offset(world.getBlockState(currentPos).getValue(FACING).rotateYCCW());

haha no need to get aggressive  That was just a quick hacky way how I did this and I already fixed it.

 

At the moment it works fine, so this can be closed now.

Draco is not being aggressive; he is just expressing his "WTF why" in a straightforward way

I'd say "read my signature" but I'm not sure those even exist any more. :V

 

Something something, "apparently I'm a jerk who just likes to make your life miserable."

You know, not everyone who asks something here is an expert. Beginners like me don't get everything right the first time, and I think that's okay. Feel free to just tell it me in a normal tone, but I have zero understanding for persons being that aggressive, unpleasant or unhelpful. Statements like these don't help the person who asked the question nor do they help the conversation. If that is a "straightforward way" for you, then I'll consider asking on the MMD discord in the future.

Of course it's alright to not get everything right the first time.

I think the problem here is that you are misunderstanding Draco18s' tone. Draco is a fun and helpful person who spend a lot of his time on the forum answering others' question. His occasional sarcasm keeps the conversation in a light mood, but might sometimes appear to be unfriendly (which is definitely not his intention) to people who are not used to his way of speaking, in which case all I could say is "don't take it personally; he doesn't mean that; he is trying to help you".

 

As for your problem, you should not directly use the meta of a blockstate to get the direction it is facing, as the meta of a blockstate might not directly convert to its corresponding EnumFacing (some blocks stores more than just an EnumFacing value in its meta). Instead, you should use the FACING property of the blockstate, which, if exists, always directly tells you the facing of the block. It is also faster and more readable.
