Solved "Unbreakable" fake glass

So I'm creating a plugin that spawns glass walls around a certain region up to a certain height when a player, who's in combat, tries to enter the region. I'm using sendBlockChange() to spawn the walls just for that player and I've had no problem creating them and cleaning up afterward.

The issue I'm having is that the glass block isn't a real block so players could just break the block or simply even click it and their client updates the block and removes it. I can't find a way to make these blocks unbreakable while the wall is visible because (as mentioned above) the blocks aren't real so when the player interacts with them they don't fire any events.

If anyone has an idea of how to overcome this issue and make the glass blocks unbreakable I'd really appreciate your help.

James out!

 

Nope, there isn't a block being broken.

Thanks, I'll check it out.

 

Thanks for all the help I think I've found a solution.

 

Will do once I've tested it out

 

It's very messy and needs to be cleaned up but oh well... I'll do that later (maybe..)
When the combat ends you loop the wallLocations HashMap and send the player a block update of air at the locations in the Map.

Code (Text):

public class PlayerMoveEventHandler implements Listener {

    static HashMap<UUID, ArrayList<Location>> wallLocations = new HashMap<>();

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

    @EventHandler
    public void onMove(PlayerMoveEvent e) {
if (e.getPlayer().getWorld().getName().equalsIgnoreCase("world")) {
            RegionManager region = Utils.getWorldGuard().getRegionManager(e.getPlayer().getWorld());
            CombatTag tag = new CombatTag(e.getPlayer().getUniqueId(), instance);
            if (tag.isTagged()) {
                ProtectedRegion spawn = region.getRegion("spawn");
                Location min = new Location(Bukkit.getWorld("world"), spawn.getMinimumPoint().getBlockX(), e.getPlayer().getLocation().getBlockY(), spawn.getMinimumPoint().getBlockZ());
                Location max = new Location(Bukkit.getWorld("world"), spawn.getMaximumPoint().getBlockX(), e.getPlayer().getLocation().getBlockY(), spawn.getMaximumPoint().getBlockZ());
                List<Block> blocks = Utils.blocksBetweenPoints(min, max);
                List<Location> locs = new ArrayList<>();

                for (Block block : blocks) {
                    if (e.getTo().distance(block.getLocation()) <= 5.0) {
                        if (block.getRelative(BlockFace.DOWN).getType() == Material.BEDROCK) { //Only spawn glass on the bedrock blocks around spawn claim
                            for (int i = 0; i < 25; i++) {
                                locs.add(block.getLocation().add(0, i, 0));
                            }
                        }
                    }
                }

                    if (!locs.isEmpty()) {
                        for (Location loc : locs) {
                            e.getPlayer().sendBlockChange(loc, Material.STAINED_GLASS, (byte) 14);
                            ArrayList<Location> list = new ArrayList<>();
                            if (wallLocations.containsKey(e.getPlayer().getUniqueId())) {
                                list.addAll(wallLocations.get(e.getPlayer().getUniqueId()));
                            }
                            list.add(loc);
                            wallLocations.put(e.getPlayer().getUniqueId(), list);
                        }
                    }
     
            }
        }
    }
