Help with 3x3x3 Pickaxe

[Gamerframed(JavaTownOwner]

I am making a mod and for my pickaxe i would like it to mine a 3x3x3 if you have any ideas or you know the code please help! Here is my current code:

[embed=425,349]package com.idtech.item;

 

import com.idtech.BaseMod;

 

import net.minecraft.creativetab.CreativeTabs;

import net.minecraft.entity.EntityLiving;

import net.minecraft.item.ItemPickaxe;

import net.minecraft.item.ItemStack;

import net.minecraft.util.BlockPos;

import net.minecraft.world.World;

 

public class ItemGelPickaxe extends ItemPickaxe {

 

      public static final String name = "GelPickaxe";

   

         

   

     

    protected ItemGelPickaxe() {

        super(ItemMod.toolMaterialGel);

        // TODO Auto-generated constructor stub

        setUnlocalizedName(BaseMod.MODID + "_" + name);

        this.setCreativeTab(CreativeTabs.tabTools);

    }

 

 

 

     

     

    }

Thanks,

Damn, forum names should have length cap. Also - no need for titles (I know, I know, publicity).

 

Back to problem at hand:

1. What version?

2. What kind of 3x3x3 destruction are we looking at?

* Block can be destroyed from side (side of hit) and from rotation (relative rotation of player-block). So e.g you can very well be under block, but hit it from west side.

 

"Facing" destruction is as simple as getting block and destroying all 3x3x3 behind/around it (other side of face being hit).

Pros: easy AF.

Cons: Box-destruction (kinda fakeish)

 

"Rotation" destruction will require ray tracing to know at what rotation block has been hit and using some math to pawn blocks in given direction.

Pros: You can make destruction like this: (P = player, O = block)

P

OOO

  OOO

    OOO

Cons: Quite hard if you know nothing about java/math and especially minecraft.

1.) 1.8

2.) pickaxe (want to break north, east, sout, west)

Override Item#onBlockDestroyed and also destroy blocks around.

 

As to directions - I think I saw better approach, but if you won't find it:

In your Item#onBlockDestroyed use World#rayTraceBlocks to get block and face you pawned, then, as said before - destroy blocks behind it.

Big note - all is pure theory so idk if at the moment of block #onBlockDestroyed, the Block is still in world - if not, the rayTrace will return block behind it. You could probably use other methods to do ray tracing, but then you would proabably save result in e.g @Capability (something like "last block digged").

 

Does it mean you can place cobble near obsidian wall and destroy 3x3 obsidian by pawning cobble?

So yeah - you also can use plenty other methods to slow down digging speed based on surrounding blocks, but that will require hella lot more of knowledge.

 

Everything is quite advanced (tho there  might be better ways).

If you want to learn - look into source and callbacks and actually spend few hours READING code.

so no help?

 

BUMP

What help are you expecting? There are (probably) no tutorials on this. This is pretty advanced stuff if you want to make it properly and WILL require reading actual source code. If you know nothing about how internals work, even if we would write step by step actions, you wouldn't be able to apply them.

 

I told you where to look (but note that there might be other ideas), if you have questions - ask directly where you need help.

I Can't find the code any where i am trying to see if any one know it do you?

I Can't find the code any where i am trying to see if any one know it do you?

 

He gave you the outline of what you have to do, now you as the developer have to actually implement it in code.

 

There is no way around that.

If you're doing a simple 3x3x3 cube around the block being broken, you can do that with a dirt-cheap 3-layer for-loop.  One for x, -1 to 1, one for y, -1 to 1, and one for z, -1 to 1.
