Hello, i am trying to make a Pickaxe that can destroy multiples blocks an the same time, i try by seeing the parameter of Blockstate and the parameters of the Block, but still don‘t know how to achieve it. Need help!

You need to work with BlockPos objects to destroy blocks at other positions. The BlockState is just informant about the block at a single location. 

Thanks, now i know with what i should to start?.

 

 

 

 

 

@Draco18s, how big is a Minecraft block?

And how to get the Blockstate from a nearby Block? I don‘t have a idea on how to make this. The Block class have a getStateID(Blockstate) and a geetStateByID(int ID), but it don‘t help my very much. Can anyone help me?

Take the position of the block you destroyed with the tool, then use that as your reference point to get nearby positions. Then, use the world to get the states of the block positions you got.

Wow, thanks

I have tried but it don‘t work, why? The Github link: https://github.com/DragonGamerDevelopers/NewFantasyMod/blob/1.15.2/src/main/java/mod/dragonita/fantasymod/init/ModItems.java#L39

You're using super.onBlockDestroyed incorrectly, that's not how you break blocks. See how PlayerInteractionManager#tryHarvestBlock does it to make sure you do all of the necessary checks when breaking blocks, and how to actually break the blocks properly. (And no, don't actually called tryHarvestBlock, just use it as a reference.)

if only there was a better way to do it (hint: loop)

Ask dumb questions, get dumb answers. If you meant something else by that question, perhaps you should clarify.

Do you know a simple Method to get the ServerPlayer in my Item class? If it was possible, can i get the ServerPlayer from LivingEntity?

if you are on the server you can cast

What cast? Can you give more informations?

you have a LivingEntity in onBlockDestroyed check if the entity is a player and if you are on a server using !world.isremote

then you can cast

No, i not am on a server, normally i should update the client and the server, or not?

w/ server i mean logical/Physical server in a single player game is still a server running

I am new with Server and client things, does the server automatically update the client? If yes then i will try to use your method.

Ok, i not am very good with this things, and as i have see the tutorial of @TurtyWurty, i have found a thing that can work, but i not am very good with Blockpos in Minecraft. I have see the Github about the tutorialmod: 

https://github.com/DaRealTurtyWurty/1.15-Tut-Mod/blob/master/src/main/java/com/turtywurty/tutorialmod/tileentity/QuarryTileEntity.java

I would need help on reading, then i have some troubles with reading the code. Should i create a separate Topic or not? Anyway i first not understand why Turty is doing this:

Block.spawnDrops(blockstate, world, this.pos.add(0, 1.5, 0), tileentity, entity, ItemStack.EMPTY);

Normally we not need to spawn Blocks manually, or i am false? Then this:

world.playEvent(2001, pos, Block.getStateId(blockstate));

What does this code snippet make?

But am most i not understand why it should return a boolean, why onBlockDestroyed Event and other similar events do return a boolean and not something else?
