[SOLVED]Blacklisting of blocks chosen in the config.

Ok, so I've been trying for a good amount of time now to code that damn blacklisting of blocks you choose in the config. But it seem to fail everytime I try. I'll give you the codes:
SOLVED


Here's the BlockListener; onBlockPlace:

Code:java

    @Override
    public void onBlockPlace(BlockPlaceEvent event) {
        if (event.isCancelled())
        {
            return;
        }
 
        Player player = event.getPlayer();
        Block block = event.getBlock();
        Server server = player.getServer();
 
 
 
        List<Object> blocks = plugin.config.getList("Place.Blacklist");
        if (blocks == null) {
            System.out.println("Theres no objects in the placement blacklist.");
            return;
        }
        for(Object i : blocks){
            Material material = Material.valueOf((String)i);
            if( material == null ){
                System.out.println("Invalid object ID: "+(String)i);
                continue;
            }
            if (blocks.contains(i)) {
                event.setCancelled(true);
                player.sendMessage(ChatColor.RED + "You cannot place "+ block.getType());
                break;
            }
        }

Here's the code in the main class:

the statement/declartion (don't know wich :S)

Code:java

List<Object> BlockPlace = new ArrayList<Object>();
    String[] PlaceList = {"1", "46", "7"};

And heres the config; loadConfig()

Code:java

        config.addDefault("Place.Blacklist", Arrays.asList(PlaceList));
        BlockPlace = config.getList("Place.Blacklist");
        this.getConfig().options().copyDefaults(true);
        saveConfig();

The error in the console:

Code:

And how the config list looks:

Code:

Place:
  Blacklist:
  - '1'
  - '46'
  - '7'

Also tried:

Code:java

Object[] PlaceList = {"1", "46", "7"};

instead of:

Code:java

String[] PlaceList = {"1", "46", "7"};

:/

Someone know what I'm doing wrong?

Im pretty sure that Material.valueOf() wants words, not numbers. Soooo you can either change the config to the *upper case?* worded version of the material, or you can check that if(event.getBlock().getTypeId == blablabla

 

So you mean that I should chane all objects to strings and the material type from ID to name?

Cant edit my text from android so i quote u from this one instead.. @theguynextdoor

Have you checked out the source in WorldGuard to see how they do blacklisting? They have a fairly indepth blacklist integrated...might be worth a gander.

 

Well

Code:

 if(config.getList("bla.moreBla").contains(blockID)){

blockID being event.getBlock().getTypeId();

 

@Mukrakiish wg's to complicated for me, and im coding more leightweight
@theguynextdoor thank you, I'll test it tomorrov when i get on my computer.

@theguynextdoor LOL, I just found the worlds most easy code for a simple blacklist, thank you; cause it includes some of your advice xD
