BreakEvent, WorldEdit, NotWork

I break don't wall block.
So not work...

I use WorldEdit Plugin (API).

Config:

Code:

game:
  arena1:
    x: 160
    y: 61
    z: 216
  arena2:
    x: 146
    y: 200
    z: 230

Code:

Code:

public class onBreakEvent implements Listener {

    private Main instance;
    public onBreakEvent(Main instance) {
        this.instance = instance;
    }

    @EventHandler
    public void BreakEvent(BlockBreakEvent e) {
        FileConfiguration config = instance.getConfig();
        World world = e.getPlayer().getWorld();
        Location loc = e.getBlock().getLocation();

        Vector play_arena1 = new Vector(config.getInt("game.arena1.x"), config.getInt("game.arena1.y"), config.getInt("game.arena1.z"));
        Vector play_arena2 = new Vector(config.getInt("game.arena2.x"), config.getInt("game.arena2.y"), config.getInt("game.arena2.z"));
        CuboidRegion region_play = new CuboidRegion(play_arena1, play_arena2);
        for (BlockVector block : region_play) {
            Location playloc = new Location(world, block.getBlockX(), block.getBlockY(), block.getBlockZ());
            if (playloc.equals(loc)) {
                e.setCancelled(false);
            }
            else {
                e.setCancelled(true);
            }
        }
    }
}

↓ picture (black): don't break area

 

You made it so if the block is in the arena you can break it, if not then you can't
