I have used the method onBlockActivated so that if player rightclicked the block with an arrow, it turns the arrow into an diamond

But what I wanted to do is arrow, iron ingot and gold. This three item also can be changed into a diamond

What should I do?

 

I had tried

 

if(par5EntityPlayer.getCurrentEquippedItem().itemID != (Item.arrow.itemID && Item.ingotIron.itemID))

 

But not working, anyhelp?

 

Here's my code

 

@Override
public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9){	
	if(!par1World.isRemote){
		if (par5EntityPlayer.getCurrentEquippedItem() == null)//prevents npe exceptions (NullPointerException)
			return false;
		if(par5EntityPlayer.getCurrentEquippedItem().itemID != Item.arrow.itemID)
			return false;

		par5EntityPlayer.inventory.mainInventory[par5EntityPlayer.inventory.currentItem] = new ItemStack(Item.diamond.itemID, 1, 0);
		par1World.setBlockToAir(par2, par3, par4);
	}
	return false;

Your method return false.
