Examples with EventHandler cn.nukkit.event.EventHandler used on opensource projects

Example 1 with EventHandler

use of cn.nukkit.event.EventHandler in project LuckPerms by lucko.

the class NukkitConnectionListener method onPlayerPreLogin.

@EventHandler(priority = EventPriority.LOW)
public void onPlayerPreLogin(PlayerAsyncPreLoginEvent e) {
    if (this.plugin.getConfiguration().get(ConfigKeys.DEBUG_LOGINS)) {
        this.plugin.getLogger().info("Processing pre-login for " + e.getUuid() + " - " + e.getName());
    }
    recordConnection(e.getUuid());
    /* Actually process the login for the connection.
           We do this here to delay the login until the data is ready.
           If the login gets cancelled later on, then this will be cleaned up.

           This includes:
           - loading uuid data
           - loading permissions
           - creating a user instance in the UserManager for this connection.
           - setting up cached data. */
    try {
        User user = loadUser(e.getUuid(), e.getName());
        this.plugin.getEventFactory().handleUserLoginProcess(e.getUuid(), e.getName(), user);
    } catch (Exception ex) {
        this.plugin.getLogger().severe("Exception occurred whilst loading data for " + e.getUuid() + " - " + e.getName());
        ex.printStackTrace();
        // deny the connection
        this.deniedAsyncLogin.add(e.getUuid());
        e.disAllow(Message.LOADING_ERROR.asString(this.plugin.getLocaleManager()));
    }
}

Example 2 with EventHandler

use of cn.nukkit.event.EventHandler in project LuckPerms by lucko.

the class NukkitConnectionListener method onPlayerQuit.

// Wait until the last priority to unload, so plugins can still perform permission checks on this event
@EventHandler(priority = EventPriority.MONITOR)
public void onPlayerQuit(PlayerQuitEvent e) {
    final Player player = e.getPlayer();
    // Remove the custom permissible
    try {
        PermissibleInjector.unInject(player, true);
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    // Handle auto op
    if (this.plugin.getConfiguration().get(ConfigKeys.AUTO_OP)) {
        player.setOp(false);
    }
    // Register with the housekeeper, so the User's instance will stick
    // around for a bit after they disconnect
    this.plugin.getUserManager().getHouseKeeper().registerUsage(player.getUniqueId());
    // force a clear of transient nodes
    this.plugin.getBootstrap().getScheduler().doAsync(() -> {
        User user = this.plugin.getUserManager().getIfLoaded(player.getUniqueId());
        if (user != null) {
            user.clearTransientNodes();
        }
    });
}

Example 3 with EventHandler

@EventHandler(priority = EventPriority.LOWEST)
public void onWorldChange(EntityLevelChangeEvent e) {
    if (e.getEntity() instanceof Player) {
        Player player = (Player) e.getEntity();
        this.plugin.getContextManager().invalidateCache(player);
        this.plugin.refreshAutoOp(this.plugin.getUserManager().getIfLoaded(player.getUniqueId()), player);
    }
}

Example 4 with EventHandler

use of cn.nukkit.event.EventHandler in project LuckPerms by lucko.

the class NukkitConnectionListener method onPlayerLogin.

@EventHandler(priority = EventPriority.LOWEST)
public void onPlayerLogin(PlayerLoginEvent e) {
    /* Called when the player starts logging into the server.
           At this point, the users data should be present and loaded. */

        return;
    }
    // Care should be taken at this stage to ensure that async tasks which manipulate nukkit data check that the player is still online.
    try {
        // Make a new permissible for the user
        LPPermissible lpPermissible = new LPPermissible(player, user, this.plugin);
