Solved Check if Player is Line of Sign

So, I'm making a protection plugin, and people can protect land in a 25 radius using a sign. The problem is that people can still break in the 25 block radius from the sign. Help is appreciated!

Code:

@EventHandler
    public void onBreak(BlockBreakEvent event) {
        Player player = event.getPlayer();
        int radius = 25;
        Location loc= player.getLocation();
       
        for(int x = (int) (loc.getX() - radius); x < loc.getX() + radius; x++ ) {
             for(int y = (int) (loc.getY() - radius); y < loc.getY() + radius; y++ ) {
                 for (int z = (int) (loc.getZ() - radius); z < loc.getZ() + radius; z++ ) {
                     
                     Block block = player.getWorld().getBlockAt(x, y, z);
                     
                     if (block.getType().equals(Material.WALL_SIGN) || block.getType().equals(Material.WALL_SIGN) ) {
                         Sign sign = (Sign) player.getWorld().getBlockAt(x, y, z);
                         
                          if (sign.getLine(0).equals("§8[§9Protected§8]")) {
                              if (!player.getName().equals(sign.getLine(1))) {
                                  event.setCancelled(true);
                              }
                          }
                     }
                 }
             }
        }
    }

There is an error, but I don't know where it is, considering my class name isn't in it.

Caused by: java.lang.ClassCastException

I don't know if the loop is messed up, or the block itself.

 

Caused by: java.lang.ClassCastException
Error when Casting Sign sign = (Sign) player.getWorld().getBlockAt(x, y, z);

 

@justin_393

Thanks, but how do I make sure it's a sign though, and then read the name.

 

if (player.getWorld().getBlockAt(x,y,z).getType() == Material.SIGN_POST) {
//your code here
}

 

@justin_393

Sorry, I mean how do I make a variable since I already checked that its a sign post/wall sign, that I could use getLine() for.

 

I honestly have no clue, I've never messed with Signs :/
Maybe @nverdier would know?

 

@BrickBoy55 Once you've assured it's a sign, just cast the block to a sign.

 

@nverdier That's what he did, but it was throwing out a java.lang.ClassCastException exception

@BrickBoy55
Typo? if (block.getType().equals(Material.WALL_SIGN) || block.getType().equals(Material.WALL_SIGN) )

@justin_393 @BrickBoy55 Oh, you have to cast the block's state (i.e. Block#getState()) to Sign. Sorry for my forgetfulness, I suppose.

 

ah, that makes sense. I'll have to remember that if I ever mess with Signs.

 

@nverdier

Code:

Block block = player.getWorld().getBlockAt(x, y, z);
                     
if (block.getType().equals(Material.WALL_SIGN) || block.getType().equals(Material.WALL_SIGN) ) {
             Sign sign = (Sign) block.getState();

Would that work? I don't have anyone to test it with right now :/

I got it working:

Solution:

Code:

    @EventHandler
    public void onBreak(BlockBreakEvent event) {
        Player player = event.getPlayer();
        int radius = 25;
        Location loc= player.getLocation();
       
        for(int x = (int) (loc.getX() - radius); x < loc.getX() + radius; x++ ) {
             for(int y = (int) (loc.getY() - radius); y < loc.getY() + radius; y++ ) {
                 for (int z = (int) (loc.getZ() - radius); z < loc.getZ() + radius; z++ ) {
                     
                     Block block = player.getWorld().getBlockAt(x, y, z);
                     
                     if (block.getState() instanceof Sign) {
                         Sign sign = (Sign) block.getState();
                         
                          if (sign.getLine(0).equals("§8[§9Protected§8]")) {
                              if (!player.getName().equals(ChatColor.stripColor(sign.getLine(1)))) {
                                  event.setCancelled(true);
                              }
                          }
                     }
                 }
             }
        }
    }
