Fixing hidePlayer

I have made a plugin that runs "The Walls" with spectators. The spectators are invisible, not meant to interact with the terrain, or to harm players. Some issues with hidePlayer...

• Projectiles are stopped when a spectator is in the way
• Blocks cant be placed where a spectator is
• Spectators can push players off a ledge (not tested)

I think this could all be fixed by adding a check during PlayerMoveEvent by pushing a spectator away when a gamer is near them. How would I be able to do this without doing too many CPU intensive checks?

 

You could try something using PlayerVelocityEvent and check to see if a player is in the spot where the player previously was, to stop the pushing.

 

Thanks for the help! That is one solution to a small part of the problem and doesn't seem very practical. The pushing isn't the biggest issue, mostly the block placement. Any other help?

Perhaps, when a spectator is within 10 blocks of a gamer, push the spectator away from the gamer. Not sure how to accomplish this :/

 

You must post this at Bukkit Project and Community Feedback since they must fix this from the server file, not that you could try to fix it by any plugin because is useless.

 

I didn't have a fix for the player pushing, So heres my fix for the block placing.

Code:

 @EventHandler(priority = EventPriority.LOWEST)
  public void onInteract(PlayerInteractEvent event) {
    Player p = event.getPlayer();
    if ((!spectate(p) || plugin.buildMode.contains(p.getName()))
        && !event.isCancelled()) {
      // Check for entity
      Location sLoc = event.getClickedBlock().getLocation();
      BlockFace blockFace = event.getBlockFace();
      sLoc.add(blockFace.getModX() + 0.5, blockFace.getModY() + 0.5,
          blockFace.getModZ() + 0.5);
      for (Player player : Bukkit.getOnlinePlayers()) {
        if (spectate(player)) {
          Location loc = player.getLocation();
          if (sLoc.getX() + 2 > loc.getX() && loc.getX() > sLoc.getX() - 2
              && sLoc.getZ() + 2 > loc.getZ() && loc.getZ() > sLoc.getZ() - 2
              && sLoc.getY() + 2 > loc.getY() && loc.getY() > sLoc.getY() - 2) {
            loc.setY(loc.getWorld().getHighestBlockYAt(loc) + 5);
            player.teleport(loc);
            player.setFlying(true);
            player.sendMessage(ChatColor.GREEN + "Stay away from gamers!");
          }
        }
      }
    }
  }

This only works for invisible players.

As for players standing in front of projectiles.

In the end I just made them get banned from the rest of the game on contact.

I maintain a server called "Archergames"

If you want to see what I've done with it, Just google the name. You should be able to find it.
