[1.10] Placing a block when a vanilla item is used

[cross-posted from Minecraft Forum]

I'm in the process of adding a firepit - to make it, you click on the ground with a stick. That part was easy enough. I'm using PlayerInteractEvent.RightClickBlock.

The only problem is, it doesn't account for blocks that can be activated, such as doors or containers. If you right click on a door, for example, it places the stick as a firepit. Is there a way to check and see if the block you're right clicking on can be activated?

Alternatively, is there a better solution to this than using the RightClickBlock event? I had to copy a chunk of code from ItemBlock.java, and I'd much rather use code that's already there, rather than duplicate it into my own code.

PS. This is my first Minecraft mod, but I'm a well-established software engineer.

Current code is as follows. It's a bit rough around the edges - I'm in hack mode.

  @SubscribeEvent
  public void onRightClickBlock(PlayerInteractEvent.RightClickBlock event) {
    if(event.getItemStack() != null) {
      Item item = event.getItemStack().getItem();
      
      if(item == Items.STICK) {
        if(event.getWorld().getBlockState(event.getPos()).getBlock() == ModBlocks.FIRE_PIT) {
          
        } else {
          //TODO: Don't do this if it's something you can interact with... door, container, etc.
          
          World world = event.getWorld();
          BlockPos pos = event.getPos();
          ItemStack stack = event.getItemStack();
          EntityPlayer player = event.getEntityPlayer();
          EnumFacing facing = event.getFace();
          
          IBlockState iblockstate = world.getBlockState(pos);
          Block block = iblockstate.getBlock();
          
          if(!block.isReplaceable(world, pos)) {
            pos = pos.offset(facing);
          }
          
          if(stack.stackSize != 0 && player.canPlayerEdit(pos, facing, stack) && world.canBlockBePlaced(ModBlocks.FIRE_PIT, pos, false, facing, null, stack)) {
            IBlockState iblockstate1 = ModBlocks.FIRE_PIT.onBlockPlaced(world, pos, facing, 0, 0, 0, 0, player);
            
            if(placeBlockAt(stack, player, world, pos, iblockstate1)) {
                SoundType soundtype = world.getBlockState(pos).getBlock().getSoundType(world.getBlockState(pos), world, pos, player);
                world.playSound(player, pos, soundtype.getPlaceSound(), SoundCategory.BLOCKS, (soundtype.getVolume() + 1.0F) / 2.0F, soundtype.getPitch() * 0.8F);
                
                event.setUseItem(Result.ALLOW);
            }
          }
        }
      }
    }
  }
  
  public boolean placeBlockAt(ItemStack stack, EntityPlayer player, World world, BlockPos pos, IBlockState newState) {
    if(!world.setBlockState(pos, newState, 3)) {
      return false;
    }
    
    IBlockState state = world.getBlockState(pos);
    if(state.getBlock() == newState.getBlock()) {
      ItemBlock.setTileEntityNBT(world, player, pos, stack);
      newState.getBlock().onBlockPlacedBy(world, pos, state, player, stack);
    }
    
    return true;
  }
