1.8 Invisibility bug?

[Notifyz]

Hey,

so recently me and my friends found out that on server(1.7.10 spigot/paper/bukkit version) if player has invisibility potion active and you join through 1.8 you do not see player but you do see his nametag, so 1.8 clients can see users which are invisible.

Nope. There is no way if your main version is 1.7

LOL, you can check what version they are using and deny login based on that factor. It's very very simple code.

thats for protocolsupport ........ protocolsupport is for 1.8+ ... o my god

lmao sure.

Used it myself, works fine.

then help him

To what code a fix to stop the nametag issue or disallow certain players to join the server? The first one is just to send a packet to all clients that aren't in the players Faction or allied factions to remove the players PlayerInfo (PacketOutPlayerInfo), then when the invis goes away resend the packets. Probably would take some messing with to get working perfectly. The other one is to get the CraftPlayer's playerConnection and get their client version from there, not hard. Just really depends on what you want to do, disallow 1.8 with the problems it brings (a percentage of hacked clients are 1.8, this nametags bug) or have someone fix your scoreboard to patch this bug. I'm not gonna 'spoon feed' anyone but here's the general idea of what to do, if you know Java and the various apis related with mineman coding it's pretty simple.

It is simple as you said but I do not want to block users playing on 1.8.
Oh and by the way I tried getting version and I think this is what you meant right?
Player player;
if (((CraftPlayer) player).getHandle().playerConnection.networkManager.getVersion() >= 47) {

You're not a developer then.[DOUBLEPOST=1498803928][/DOUBLEPOST]If you lack the ability to think logically about this little task I feel sorry for you wasting your time.

May I ask what problems do you have?
So if I cannot get something working you have to start trashing I am not developer and that I cannot think logically?
You think that reply you wrote touched me?
Try helping and stop acting like a dickhead.

@EventHandler
public void onLogin(PlayerLoginEvent event) {
  CraftPlayer player = (CraftPlayer) event.getPlayer();
  int version = player.getHandle().playerConnection.networkManager.getVersion();
  if (version < 4 || version > 5) {
    event.disallow(Result.KICK_BANNED, "Sorry, your client version is not supported by our server.\nPlease consider using Minecraft 1.7.");
  }
}
