Tera Shock Server Emu!!

[narcis96]

Hi guys,

I'll write here what I think the state of the TERA private server (emulator) dev community is.

So,
@Luciole working on a c# version, right?
@P5yl0 is working on a newer version of his emulator, if i it understand correctly
@wankers14 worked on a project, idk the state of hi's project atm.
@clofriwen tried to write a server in C, idk where he's at these days.
@narcis96 i'm working on my Skylake project , (as i have time)
@OtherTeraDevs sorry if a left anyone out.
@Anonymous <- there is an other guy i know who is working very hard for quite some time now on a private TERA server. I think he has the most potential, but idk about what hes gonna do with it when done (in terms of open source or eaven publishing a compiled verision.), we'll see.

In my endeavor with this project i've learned a lot about TERA and the requirements of making a private server (emulator) for it.
A LOT of data necessary for a successful server dev is missing from the TERA Client Data Center(DC).
This data is server side only and very hard to come by.
But luckily i've managed to gather most of the missing data , this data needs to be restored manually and that alone is a lot of work.
I have my own theories and ideas on the right architecture or language to write it with/in , but thats my opinion.

Atm i'm thinkg to make my src public, but idk...

Please let me know what's your thought on this subject.
@P5yl0 @Luciole @wankers14 @clofriwen @OtherTeraDevs

Thanks.

PS. Feel free to DM me for questions.

I think that the best thing is to make a discord and unite us all to make a stable and updated server. without stamina with the latest costumes, pet frames and most importantly, classes. What is the most important. a server where you can play both offline and online with friends in hamachi for example. to make dungeons
It is very boring to create a server without brawlers without ninjas without everything current. I promise to participate in some way in a project of tera because I love this game, what I hate are the original servers of enmasse or gameforge that already their economy is broken and it is difficult to get the things you want. that's why I would rather have my own server and enjoy it alone or with friends on a hamachi-type lan network.

Enter Game work now with client 9203 but we still need find someone who have this parsers to get last Data files!
We have parser but this will keep much time to update!

[gatitoxp]

We can divide the work, people who program the skills. others who compile what is missing. others to draw and make new artistic designs. and 3d modeling to create new clothes. A single person programming this is going to last a long time.

@narcis96 I'm working on a 27.07 (Classic server EU version) based on the Java version. A lot of changes have been made, i'll make a changelog soon when i'll have time.

I'm agree with things there:
- Make a TERA dev discord (or whatever) with only dev people inside, for help, share.
- A lot of data is missing from the client (NPC spawns, loots, ...)

[narcis96]

When i'm talking about missing data, i'm talking about missing files and missing fields.
For eg. this is the actual skill data structure, (server side form)

@narcis96 can you upload pls your files?

[narcis96]

My version is still under heavy dev. Its not playable.
If there are any c++ devs who want to collab dm me.

@narcis96 hi i'm still working on my project, updated regularly (dungeon, quest, guild, party, mail, broker, drops, and many other features i'm currently on skills)

some features :

[narcis96]

Good Job!
I have 2 questions:
-What would the benchmarks say about your code, in terms of speed?
-How many concurrent players will your server be able to support before hitting server created lag?

[wankers14]

@narcis96
So I develop on aion for 10 years I am inspired, the code is in Java, mysql database, the data in XML I optimize the code for speed. Starting on a machine with 4 cores 4 threads and 16gb of ram a hundred people can all play in perfect stability. I coded the channel system in play to help a lot with the stability I had no choice but to add the channel system (a channel contains these own mobs, players, gathers, game object, drops, servant. ..) moreover the channel system is used for the dungeons on tera hence the importance of having it in place. Just for dungeons I have an instance engine to script them.

some exemple :

for mysql DAO

@Override
    public void createPlayer(Player player) {
        WorldPosition pos = player.getWorldPosition();
        PlayerAppearance app = player.getPlayerAppearance();
        PreparedStatement st = DB
                .prepareStatement("INSERT INTO players(`id`, `name`, race, gender, class, level, exp, rested_exp, max_rested_exp, hp, mp, creation_time, last_online, description, settings, map_id, x, y, z, h, channel," +
                        " account_id, awaken_level, laurel, achievment_points, fatigue, world_map, world_guard, arena_id, delete_time, appearance, appearance2, details, shape, ban, ban_time, new_player, change_name) " +
                        "VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");

        try {
            st.setInt(1, player.getId());
            st.setString(2, player.getName());
            st.setString(3, player.getRace().toString());
            st.setString(4, player.getGender().toString());
            st.setString(5, player.getPlayerClass().toString());
            st.setInt(6, player.getLevel());
            st.setLong(7, player.getExperience());
            st.setLong(8, player.getCurrentRestedExperience());
            st.setLong(9, player.getMaxRestedExperience());
            st.setLong(10, player.getCurrentStats().getHp());
            st.setLong(11, player.getCurrentStats().getMp());
            st.setTimestamp(12, player.getCreationTime());
            st.setTimestamp(13, player.getLastOnlineTime());
            st.setString(14, player.getDescription());
            st.setBytes(15, player.getUserSettings());
            st.setInt(16, pos.getMapId());
            st.setFloat(17, pos.getX());
            st.setFloat(18, pos.getY());
            st.setFloat(19, pos.getZ());
            st.setInt(20, pos.getHeading());
            st.setInt(21, pos.getChannelId());
            st.setInt(22, player.getAccount().getId());
            st.setInt(23, player.getAwakenLevel());
            st.setString(24, player.getLaurel().toString());
            st.setInt(25, player.getAchievmentPoints());
            st.setInt(26, player.getGatherCraftPoints());
            st.setInt(27, pos.getWorldMapWorldId());
            st.setInt(28, pos.getWorldMapGuardId());
            st.setInt(29, pos.getAreaNameId());
            st.setTimestamp(30, player.getDeletionTime());
            st.setBytes(31, app.getAppearance());
            st.setBytes(32, app.getAppearance2());
            st.setBytes(33, app.getDetails());
            st.setBytes(34, app.getShape());
            st.setBoolean(35, player.isBan());
            st.setTimestamp(36, player.getBanTime());
            st.setBoolean(37, player.isNewPlayer());
            st.setBoolean(38, player.isNamechange());
            st.executeUpdate();
        } catch (SQLException e) {
            log.error("Can't inser player", e);
        } finally {
            DB.close(st);

I see. Great job!
Have you started on the skill system for TERA?
If so, how far have you gone?

[wankers14]

Just for the moment i have create all packets and i have create template

[narcis96]

The skill system along with the abnormality system makes TERA , TERA.
These 2 systems, specially the skill system, are the back bone of the server, they are involved in most of the design decisions as they are most of the CPU load, getting them right is crucial for a successful server.
Good Luck! And keep up the good work!

[karyzir]

We need discord server to coordinate tera stuff, works, not for money profit, right now Tera Emu`s in rudimentary state, we dont have client tools for modding, but we have leaked UE3 sources lol) I rly want make classic server(Browler included) but bored doing myself(
