[1.10.2] Hammer 3x3x1

[DarkProd02]

Hi,

I tried to make a hammer for my mod ,i tried some code but they don't work .

 

Someone has an idea how?

Thanks ,

I believe you have to override the onBlockDestroyed method and destroy the 8 blocks around the one that the hammer itself broke. You need to know somehow what side did the player break this block from to determine in which direction you going to destroy the other 8. Back in 1.8.9 MovingObjectPosition was one way to do it. Not sure on 1.10.2 what works.

Yes i tried to do that but this doesn't work

[Matryoshika]

Call Item::rayTrace to gain access to a RayTraceResult, which can give you a block, and specifically the side of the block. Be sure to checkRayTraceResult#Type though. It might be nothing "MISS" or an entity "ENTITY".

 

I would call said rayTrace method in an override of Item::onBlockDestroyed, and verify that the result's blockstate equals the blockstate being destroyed.

Can you give me the code please?

If you just copy/paste, then what's the point of you making the mod?

No.
This forum is for helping people with their own code.
Giving out copy-paste-code is not helpful, neither to you, who won't learn what the actual code does, nor us, who'd have to write detailed tutorials on where, how, why and when the code does whatever it does.

I've told you how to gain access to a block that the player is looking at, and how to get the specific side as well (Item::rayTrace).
Now try and use it.
We can help you along the way. We will not send you off with a free ticket.

ok here is my code : 

public boolean onBlockDestroyed(ItemStack stack, World worldIn, IBlockState state, BlockPos pos, EntityLivingBase entityLiving)
  {
    if ((!worldIn.isRemote) && 
      ((entityLiving instanceof EntityPlayer)))
    {
      EntityPlayer player = (EntityPlayer)entityLiving;
      
      RayTraceResult raytraceresult = rayTrace(player.getEntityWorld(), player, true);
      if (raytraceresult != null)
      {
        BlockPos[] blockPosesNS = { new BlockPos(pos.getX() + 1, pos.getY(), pos.getZ()), new BlockPos(pos.getX() + 1, pos.getY() + 1, pos.getZ()), new BlockPos(pos.getX() + 1, pos.getY() - 1, pos.getZ()), new BlockPos(pos.getX(), pos.getY() + 1, pos.getZ()), new BlockPos(pos.getX(), pos.getY(), pos.getZ()), new BlockPos(pos.getX(), pos.getY() - 1, pos.getZ()), new BlockPos(pos.getX() - 1, pos.getY(), pos.getZ()), new BlockPos(pos.getX() - 1, pos.getY() + 1, pos.getZ()), new BlockPos(pos.getX() - 1, pos.getY() - 1, pos.getZ()) };

I'm sorry, but... and?
Your code doesn't actually break any blocks...
It just ends with "i have these blocks."

 

You are validating the block's materials, but nothing else... of course the blocks won't break.

At the end of your for-each blockpos loop, call ForgeHooks#canHarvestBlock (to make sure the player can break these blocks (in the case of protection plugins etc)) and if they can, call World::destroyBlock with true to make sure the block's drops actually drop.

[Matryoshika]

That is not what I said.
When someone states "call method x" you do not override it as you did here, and especially not in a class that is not an instance of the class using the original method...

What you did is re-create a method that blindly says "yes" whenever it is asked.
Calling a method means you actually call the method. Here that means running if(ForgeHooks.canHarvestBlock(Block, Player, World, BlockPos)){//run code here if player can break this block}

Yes, and no.
Never use null unless you are absolutely sure that it is harmless. Most of the time, using null with cause nullpointerexceptions, aka crash the game.
Use World::getBlockState::getBlock to get the block.

As I mentioned in my previous post, ForgeHooks::canHarvestBlock checks for you if the player CAN break the block. If it returns true, use World::breakBlock with true as the second argument to actually break the block.

Why you have the onUpdate ?

Can you do a Switch with the result of the raytrace instead of those if else statements? That will probably make things cleaner.

 

Also I think it's not breaking blocks, because when you actually call the worldIn.detroyBlock you passing "pos" and not "blockPos" that you using on the for loop.
