[Kronos] Removing Forum Login, Fixing Friends Chat and Clan Chat, Password Saving

As the title says, this is for Removing Forum Login, Fixing Friends Chat and Clan Chat and adding Password Saving.

Lots of people asked for this so I thought I would release.

Do not use the old thread I made about removing forum login and UNDO any changes that you made.
It is recommended that you re-download Kronos if you used that tutorial.

Server must have offline mode set to FALSE

The purpose of this is to use central server (friends/clan chat) without using forum settings.

If you don't have mysql databases set up you must comment out or delete these lines in [io.ruin > Server.java] (kronos-server files)

Code:

---

            siteDb = new Database(properties.getProperty("database_host"), "kronos", properties.getProperty("database_user"), properties.getProperty("database_password"));
            gameDb = new Database(properties.getProperty("database_host"), "game", properties.getProperty("database_user"), properties.getProperty("database_password"));
            forumDb = new Database(properties.getProperty("database_host"), "community", properties.getProperty("database_user"), properties.getProperty("database_password"));

            DatabaseUtils.connect(new Database[]{gameDb, forumDb, siteDb}, errors -> {
                if (!errors.isEmpty()) {
                    for (Throwable t : errors)
                        logError("Database error", t);
                    System.exit(1);
                }
            });

Step One: Removing Forum Login

REQUIRED FOR FIXING FRIENDS CHAT AND CLAN CHAT

This is for removing forum login so you can use the central server or else you wouldn't be able to use the central server features (Clan/Friends chat).

Go to io.ruin.central.model.world > WorldLogin.java (kronos-central-server)

Replace everything with this:

Code:

}

---

Now go to io.ruin.model.entity.player > PlayerLogin.java

Find this:

Code:

---

  private void send() {
        if(OfflineMode.loadPlayer(this))
            return;
        CentralClient.sendLogin(info.ipAddress, info.name, info.password, info.email, info.macAddress, info.uuid, info.tfaCode, info.tfaTrust, info.tfaTrustValue & 0xff);
    }

---

Replace with:

Code:

---

private void send() {
        info.name = info.name.replaceAll("_", " ");
        if(OfflineMode.loadPlayer(this))
            return;
        CentralClient.sendLogin(info.ipAddress, info.name, info.password, info.email, info.macAddress, info.uuid, info.tfaCode, info.tfaTrust, info.tfaTrustValue & 0xff);
    }

---

Now go to io.ruin.central > Server.java

Find:

Code:

---

   
    public static boolean isOnline(int userId, String name) {
        int limboWorld = Limbo.get(userId);
        if (limboWorld != -1) {
            System.err.println(name + " is in limbo on world " + limboWorld + "!");
            return true;
        }
        for (World world : worlds) {
            if (!world.hasPlayer(userId)) continue;
            System.err.println(name + " is online in world " + world.id + "!");
            world.sendOnlineCheck(userId);
            return true;
        }
        return false;
    }

---

Replace it with:

Code:

---

public static boolean isOnline(int userId, String name) {
        int limboWorld = Limbo.get(userId);
        if (limboWorld != -1) {
            System.err.println(name + " is in limbo on world " + limboWorld + "!");
            return true;
        }
        for (World world : worlds) {
            if (!world.hasPlayer(name)) continue;
            System.err.println(name + " is online in world " + world.id + "!");
            world.sendOnlineCheck(name);
            return true;
        }
        return false;
    }

---

Now go to io.ruin.central.model.world > World.java

Add these 2 methods:

Code:

---

    public Player get(String name) {
        for (Player player : this.players) {
            if (!player.name.equalsIgnoreCase(name)) continue;
            return player;
        }
        return null;
    }

    public boolean hasPlayer(String name) {
        return this.get(name) != null;
    }

---

Now go to io.ruin.central.network > WorldSender.java

Replace sendOnlineCheck method with this

Code:

---

    public void sendOnlineCheck(String name) {
        OutBuffer out = new OutBuffer(5).sendFixedPacket(4).addString(name);
        this.write(out);
    }

---

Now for changing player saving usernames instead of userids (You must do this):

Go to io.ruin.central.model > Player.java

Replace load, save, and getSaveFile methods with these:

Code:

---

    public static String load(String username, World world) throws IOException {
        File file = Player.getSaveFile(username, world);
        return file.exists() ? new String(Files.readAllBytes(file.toPath())) : "";
    }

    public static boolean save(String username, World world, String json) {
        try {
            File file = Player.getSaveFile(username, world);
            Files.write(file.toPath(), json.getBytes(), new OpenOption[0]);
            return true;
        }
        catch (IOException e) {
            Server.logError(e.getMessage());
            return false;
        }
    }

    private static File getSaveFile(String username, World world) throws IOException {
        File folder = new File(System.getProperty("user.home") + "/Desktop/Kronos/_saved/players/" + world.stage.name().toLowerCase() + "/" + world.type.name().toLowerCase());
        if (!(folder.exists() || folder.mkdir() || folder.mkdirs())) {
            throw new IOException("Failed to make player saves folder for world: " + world.id + " (" + world.activity + ")");
        }
        return new File(System.getProperty("user.home") + "/Desktop/Kronos/_saved/players/" + world.stage.name().toLowerCase() + "/" + world.type.name().toLowerCase() + "/" + username + ".json");
    }

---

Now go to io.ruin.central.network > WorldDecoder.java

Find:

Code:

---

if (opcode == 3) {

---

Replace that whole if statement with this:

Code:

---

        if (opcode == 3) {
            int userId = in.readInt();
            int attempt = in.readUnsignedByte();
            String json = in.readString();
            Player player = Server.getPlayer(userId);
            if(player == null) {
              return;
            }
            if (!Player.save(player.name, world, json)) {
                return;
            }
            if (attempt != -1) {
                world.sendSaveResponse(userId, attempt);
            }
            return;
        }

---

Forums should now be fully removed and you can use the central server freely without any issues.

Step Two: Fixing Friends and Clan Chat

To save time we are just going to replace everything in these 7 class files:

And that's all you need to do for Friends and Clan chat to work.

Step Three: Password Saving (Do This AFTER Friends and Clan Chat fix to avoid bugs/errors)

Go to io.ruin.model.entity.player > PlayerLogin.java

Find:

Code:

---

        if (player == null) {
                deny(Response.ERROR_LOADING_ACCOUNT);
                return;
            }

---

Right below that add:

Code:

---

            if(player.getPassword() != null) {
                if (!info.password.equalsIgnoreCase(player.getPassword())) {
                    deny(Response.INVALID_LOGIN);
                    return;
                }
            }

---

Now go to io.ruin.model.entity.player > Player.java

Find

Code:

---

    private String password;

---

Change it to

Code:

---

    @ Expose private String password;

---

Your accounts will now be password protected

If you ever get this error, ignore it, it won't impact anything:

Code:

---

I've followed the tutorial, and noticed a bug with the clan chat. If you make a clan channel, and join that it'll work fine. But once you logout, turn off the servers and back on, then re-login again it will say "you're already in a channel", but you're not in a channel when you login..

Also, this snippet may need to be updated now for the new changes that was made from this. [Only registered and activated users can see links. Click Here To Register...] Since, we're not using OfflineMode, anymore.

Can you make thread how to switch to ips forum?

Do not use the old thread I made about removing forum login and UNDO any changes that you made.
It is recommended that you re-download Kronos if you used that tutorial.

I followed everything u posted here, and have no errors, but i'm afraid if still getting bugs from ur old thread bro, also the clan chat still doesn't work and the pms still showing me "Loading friends/Ignore list.. Please wait"

Good job with this. Thanks for contributing.

Should you not recompile right away? Cuz the first bit already giving me issues.
