knowing blocks locations

I want to do a plugin where u have a machine textured skull block that when clicked with right button open an inventory, but i tried to use metadata to put a "ismachine" data inside the block but then i discovered that metadata is gone when u restart the server, what could I do to differentiate the blocks from other skullblocks ?

Thanks

As for the block location(s), make a local variable, initialize it as the block you want the location of, then use #getLocation().

 

but i want to put and take machines, if i initialized it would only show the same location

 

@victot21
When you break the skull that is in the location, remove it from the location and turn the drop into a machine item.

 

if I use a Location variable, when i restart the server it shouldn't go back to default ?
and if so how i'm going to put it back on the list ?

 

@victot21
Store the locations in a list in the config. When you reload/in the onEnable, set the list to be equal to the list in the config.

 

i tried to save the strings in the config and to read them saving works but reading doesn't and it does not tell me any errors

        float locy = Integer.parseInt(block[2]);

                   }

       }
        player.openInventory(inv);
    
               }
        }
    }

 

Code:

        if (getConfig().getString("Location")!=null){

This will always return null because there is no string at just Location. You need to also provide a number (Or, better yet, just get the keys for that configuration section.)

Code:

        if(e.getClickedBlock().getLocation() == blockl) {

Also, this will never be true. By creating a new instance of Location for the check, the instances will never be the same as the clicked block's location. Instead, use .equals()
