Hello, as you can see in the title I want to know how to change one block turn into another block by right clicking it with an item.

Also, it would be changing one custom furnace into another, maybe this changes how it works maybe not, but that's what I want to know.

if you want to do this with the item you can do

@Override
public boolean onItemUse(ItemStack par1ItemStack,
	EntityPlayer par2EntityPlayer, World par3World, int par4, int par5,
	int par6, int par7, float par8, float par9, float par10)
{
	if(!par3World.isRemote && par1World.getBlockID(par4, par5, par6) == myBlock.blockID)
	{
		par3World.setBlock(par4, par5, par6, myOtherBlock.blockID);
	}

	return super.onItemUse(par1ItemStack, par2EntityPlayer, par3World, par4, par5,
		par6, par7, par8, par9, par10);
}

 

if you want this in the block, similarly you can do:

@Override
public boolean onBlockActivated(World par1World, int par2, int par3,
	int par4, EntityPlayer par5EntityPlayer, int par6, float par7,
	float par8, float par9)
{

	if(par5EntityPlayer.getHeldItem().itemID == myItem.itemID)
	{
		par5EntityPlayer.getHeldItem().stackSize -= 1; //only if you want to use the item when you do this.
		if(par1World.isRemote)
		{
			par1World.setBlock(par2, par3, par4, myBlock.blockID);
		}
	}
	return super.onBlockActivated(par1World, par2, par3, par4, par5EntityPlayer,
		par6, par7, par8, par9);
}

 

 

EDIT:

This could cause some funky stuff with containers so make sure you think of a way to handle the inventory when you do this, Not going to do that for you, as it would take me too long and I've got stuff to do for my mod.

if you want to do this with the item you can do

@Override
public boolean onItemUse(ItemStack par1ItemStack,
	EntityPlayer par2EntityPlayer, World par3World, int par4, int par5,
	int par6, int par7, float par8, float par9, float par10)
{
	if(!par3World.isRemote && par1World.getBlockID(par4, par5, par6) == myBlock.blockID)
	{
		par3World.setBlock(par4, par5, par6, myOtherBlock.blockID);
	}

	return super.onItemUse(par1ItemStack, par2EntityPlayer, par3World, par4, par5,
		par6, par7, par8, par9, par10);
}

	{
		par5EntityPlayer.getHeldItem().stackSize -= 1; //only if you want to use the item when you do this.
		if(par1World.isRemote)
		{
			par1World.setBlock(par2, par3, par4, myBlock.blockID);
		}
	}
	return super.onBlockActivated(par1World, par2, par3, par4, par5EntityPlayer,
		par6, par7, par8, par9);
}

Okay, so I add this to my item class that I want to drop?

Oops, I was thinking this was posted in another topic

 

So, I add these files to both the block I want to change + the item I want to use to change to block?

not both, just one or the other

not both, just one or the other

Okay, that worked But, the item I right click doesn't go away when I right click it. I do want it to do that, how?

If you put the code in the block, use the line Yagoki put in there:

par5EntityPlayer.getHeldItem().stackSize -= 1; //only if you want to use the item when you do this.

If you put it in the item, you should be able to use the same code.

So where should I put this in the code? (I'm using it on an item)

Right after World.setBlock

Thanks! It worked
